Server crash : help !!!
Hello all, I already posted this message and got no response, I don't know how to manage this problem. I tried to upgrade to TSM 4.2.4.1 but it didn't change anything. I have a problem with my tsm server which crashes each morning during a script designed to analyse the server (different select to create a readable report) I have the following error : ANR7837S Internal error TBCOL989 detected. I am at level 4.2.3.4 on AIX 4.3.3 I tried an audit DB but I get the same error during the audit which crashes also Has anyone an idea of what's going on ?

Réf. : Accidentally issued delete volume ...
Hi, Sorry but you have deleted the files from the database. In fact, they are not erased from the the tape so a restore vol won't help. The only way I know would be to restore an old database backup, you could do it on another server if you can.

Re: retain incremental backups
Hi, I don't understand why the incremental backups should be expired if you set the backup copy group to retain data for 30 days. If you make that, you will keep all the backups for 30 days : 4 or 5 full backups and as much incremental backups than the file was modified. But I think you haven't understood one of the main caracteristics of TSM because you talk about backups like it was considered like one global entity, it's not true, each file is considered separately. If you backup filea and fileb on monday and filec and filed on tuesday, TSM won't group filea and fileb in one backup entity it will only keep the fact that their last backup date is monday. In fact, TSM will check the state of each file it has to backup. You could consider that TSM makes a full backup each day but to gain time and place, it doesn't backup again files that haven't changed, he only keeps track that the file was still there and unchanged at a precise date. The only advantage of full backup of TSM is to force it to rebackup all files in case they where not properly backed up the first time. If you wan't to keep several backups of the same file, for disaster recovery purposes, instead of backing them up again, you shoud only make copies within TSM with a backup stg command. TSM differs here from other softwares which need to backup a file again to have several copies on tape. One of the great advantages of that is that TSM uses far less tapes to backup the same amount of data with the same security level. Anyway, if you want to keep a point-in-time backup of a server in one single set of tapes, you can use the backupsets regards Etienne GUILLAUMONT e-mail : [EMAIL PROTECTED] RGB Technologie Parc d'Innovation, Bâtiment PYTHAGORE 11 Rue Jean SAPIDUS 67400 ILLKIRCH Tél : 03 90 40 60 60 Fax : 03 90 40 60 61 Richard Sims [EMAIL PROTECTED] Pour : [EMAIL PROTECTED] Envoyé par : cc : ADSM: Dist Objet : Re: retain incremental backups Stor Manager [EMAIL PROTECTED] RIST.EDU 26/06/2003 15:29 Veuillez répondre à ADSM: Dist Stor Manager We make a full backup on every Saturday and incremental backups on weekdays.

However, if I set the Backup Copy Group to retain the backups for 30 days, only the full backups will be preserved and the incrementals will be expired. Have anybody any idea? Sadly, your site is undermining the intent of the TSM product by using like a basic OS utility backup. Your company could save a lot of money by discontinuing use of TSM and just using a plain, old backup utility. TSM offers so much more in modern methods

Re: Can you use a manual tape drive for your copypool?
Hello, I did that at a customer's : One single drive LTO autoloader in which I have the primary backup pool and also the db backups and one single external DLT1 drive for offsite copies. Each day, I backup the primary pool to the DLT1. The main problem is that I had to write scripts in order to have the right tape in readwrite state and the other ones in offsite state . I found it a little tricky because it seems that TSM isn't able to check which tape is in the drive before choosing on which it will write. But as Nick wrote, the reclamation is not a real problem as if your tapes are in offsite state, TSM will use the primary tapes for reclamation.. Another possibility which have already been described in this list is to buy cheap big disks for the primary storagepools and to use the autoloader for the copypools only. But this may be expensive if you have big amounts of data to backup.

Re: progressive backup vs. full + incremental
It is right if you have 50 tapes in the tape pool. If you have only 20 tapes, TSM is fortunately not going to save 20 clients and let the others unsaved, it will put several clients on each tape. For example, I use TSM to backup several portable computers, each has about 2 gb to save, I wouldn't like to have one 40 GB tape containing 2 GB for each client. So, I don't see why collocation should use far more tapes than nocollocation. And as long as I know, It is the tape pool which is collocated and not the disk pool.

Re: progressive backup vs. full + incremental
Ok, now I understand what you meant. One solution would be to have two tape pools : one containing 20 tapes for you 50 clients, and one with 1467 volumes for the rest. If you don't want collocation for all your clients, it is the only solution I can imagine. But still it is not the diskpool which is collocated but the tape pool. But I still have a question : are your primary pools all on disk ? you are talking of copy pools. I don't think collocation is very usefull for copy pools as they are only used in case of the failure of the primary pools. So I think it is acceptable to have a slow restore time in this case as it is very unlikely (I mean having either your client and the primary pool having a problem at the same time) Etienne GUILLAUMONT e-mail : [EMAIL PROTECTED] RGB Technologie Parc d'Innovation, Bâtiment PYTHAGORE 11 Rue Jean SAPIDUS 67400 ILLKIRCH Tél : 03 90 40 60 60 Fax : 03 90 40 60 61 William Rosette [EMAIL PROTECTED]To: [EMAIL PROTECTED] JOHNS.COMcc: Sent by: ADSM: Subject: Re: progressive backup vs. full + incremental Dist Stor Manager [EMAIL PROTECTED] EDU 06/03/2003 20:56 Please respond to ADSM: Dist Stor Manager Now back to my original question of: How do you get a disk pool to go to a certain amount of tapes without the other disk pools messing them up?

Bill, If I am wrong, someone will surely correct me, but what I think happens is that when migrating the 50 clients from disk to tape, TSM will try to put each one on its own tape (as collocate says it should). So the first 20 clients each go to their own tape. Then, when client 21's turn comes around, TSM searches for a new scratch tape to hold this client. If one does not exist (because of MAX SCRATCH or simply out of scratch in the library) TSM will go back and re-use the least consumed tape
Re: progressive backup vs. full + incremental
85 to 90 backup 1 GB or less. What worries me is the smaller the backup the more nocollocated these tapes get, and more time to restore, and more time to do Backupsets, and the more go's on. I did a showvolumeusage xx on my clients in February of this year and found out that on average each node is (we call this the TSM scatter effect) spread over 121 tapes. What I see is a full restore on an average of 1 client will take 121 tape mounts (minimum). Now, we currently are nocollocate on Tapepool and Copypool (sorry about the disk pool misunderstanding) . I am trying to solve this issue without using an exorbent amount of tapes, but taking your example on the 20 computers, how long would it take for you to restore say 1 computer of the 20 like in a DR situation? and why if you don't mind explaining?

Re: progressive backup vs. full + incremental
I don't understand why collocation should use more tapes. Of course it would be probably better to have one tape by client but if you manage to backup for example 50 small clients on 20 tapes, you could use collocation without buying more tapes. The difference would be that instead of backing up each day all the clients on the last tape, resulting in each client having files on each tape, it will put 2 or 3 clients on each tape. In fact, at the end, you will probabbly have something like each client having files on 2 or three tapes. With full+incremental, depending on the regularity of your full backups, you could have a client on far more tapes, tipically 1 full per week + 4 incremental. With full+differential, you would have each client on 2 tapes, but the amount of data backed up would be bigger because a file modified just after the last full backup would be on each subsequent differential tape. And in fact, as long as I know, most software based on full+incremental are unable of collocation and use more tapes than TSM.

Re: LTO Reclamation
Hi, This performances may be normal as when you reclaim a tape, it does not read with full capacities of the drive, TSM search for the first file on the tape, reads it, search for the next file, reads it ... and so on. It's normal that the data throughput is less than the maximum of the tape because you have to add the search time to the read time.

I just checked my reclamation. A tape was being reclaimed and it took TSM 3:41:14 to do the job. The total amount of data being reclaimed was 104,711,564,841 bytes. That's about 7.8 Mb./sec.

Re: progressive backup vs. full + incremental
will be 5 tapes (4 M-Th nights, +1 for full) versus the possible maximum of 20 tapes is 20 tapes above. On the Differential/full, with full done weekly then the maximum possible tapes for restore is 2 tapes (last Differential + 1 for full) versus 5 and 20 above. Add minimum 3 minutes per tape (1 minute to load tape, 1 minute to dismount, 1 minute to locate) and I see a 2 tape restore take 30 minutes, 5 tape restore take 39 minutes and the 20 tape restore take 1 hour 24 minutes. This also depends on how the restore go's. That 3 minute per tape could be more if a tape is used more than once which I have seen happen depending which file is being restored. On the last item I disagree with the fastest way is 1 drive per computer. That means you can only restore the speed of the tape drive which might not be good if you have 1 TB of disk to restore. I think the TSM way is the best by splitting your resources. We have 10 tape drives that average 50 GB an hour per drive. If the Server and Client could handle it (which seems to be my most bottlenecks) I could go 500 GB per hour and that 1 TB would restore in 2 hours. What I can't get over is how at TSM classes they try to beat it into my head that Restores are #1 priority, why can't that be with TSM software?

Of course it would be probably better to have one tape by client but if you manage to backup for example 50 small clients on 20 tapes, you could use collocation without buying more tapes. The difference would be that instead of backing up each day all the clients on the last tape, resulting in each client having files on each tape, it will put 2 or 3 clients on each tape. In fact, at the end, you will probabbly have something like each client having files on 2 or three tapes. With full+incremental, depending on the regularity of your full backups, you could have a client on far more tapes, tipically 1 full per week + 4 incremental. With full+differential, you would have each client on 2 tapes, but the amount of data backed up would be bigger because a file modified just after the last full backup would be on each subsequent differential tape. And in fact, as long as I know, most software based on full+incremental are unable of collocation and use more tapes than TSM.

Re: Automatic checkin on a 3584?
Hello, You didn't say in what type of OS you where. If it is unix, no problem, you just have to add a sleep command. If you have a unix box within you clients, you can also install dsmadmc on it and make the script on unix which is far better for shell scripts and automations than windows. The other way is not to use a timing but to do exactly what you do manually : check for example the process before continuing.

The procedure: 1. Fill the I/O station(s) with brought back tapes to be checkin'd 2. Issue a 'checkin libvol library search=bulk status=scratch checklabel=barcode' 3. Wait a bit for a request to appear in the request queue 4. Issue a reply corresponding to what appears in 'q req' 5. Wait a bit for the whole checkin process to finish in search mode 6.

Issue a reply corresponding to what appears in 'q req' Manually, works great. My script parses all data just fine using dsmadmc in batch mode (with -id= -pass=...) and the command syntax is correct -- I know because it works fine by hand. I'm a little stuck in getting the exact timing *just right* for the delays as well as the best way to construct a while loop logic to get the timing right. It just runs through it so fast that it exits before it's got a chance to answer both requests. Detecting certain corner cases seems a little interesting when you throw in vagaries of timing, also. Alas, cheating by direct loading and using search=yes to avoid the requests isn't an option for the weekly tape swaps. ;) Does anyone happen to have a similiar script fragment or even just suggestions on how to construct the while loop 'just so'? :) Anything would be much appreciated!

Hello,
Here is what I use on AIX4.3.3 to make automatic checkin every morning, it
is done in ksh.
#!/bin/ksh
dsmadmc -id=admin -pa=admin checkin libv l20 search=bulk
checkl=barcode status=private
sleep 15
REQNO=$(dsmadmc -id=admin -pa=admin q req|grep ANR8373I| awk '{print
$2}'|tr -d ':')
dsmadmc -id=admin -pa=admin reply $REQNO
I hope it will help you.
I don't understand why you have to issue two checkin, one with
status=private and the other with status=scratch, but I am not sure I fully
understood this option and anyway, I only need the private status.
But if you need to issue both, I guess you can let TSM a long time to
finish the first checkin, something like 10 minutes. Usually, checkin of
new volumes is not that urgent.

Hi Dan,
I'm just about to do something like you, and I just have the following
idea.
From experience, a 10 sec. wait is enough for the request to be generated
in
tsm, so either a wait statement that waits 10 seconds, or creating a
for-loop that runs for about 10 seconds, and then continue.
Another idea, would be to (repeatedly) issue command q req, and on the
right
RETURN code (0), continue the script.
I can't remember how to catch the return code through dsmadmc, but I'm sure
someone else on the list can tell us. (or you could use the command with
the
outfile option, then parse the file for the info wanted.
My best choice would be to use a wait, that waits long enough for the
request to be created, just because it makes the script shorter (usually).
Rgds.

Re: Semote storage pool
I know but my customer want to do that. In fact, he bought two new servers, one with W2K and one with linux, and planned to install TSM on the linux server, but it is so complicated that we decided to install it on the W2K server. And we have 200 Gb on the Linux Server and 70 Gb on W2K So we would like to have a primary storage pool on the W2K machine and the next storage pool on the linux box. The storage on the linux box should be used very rarely. But in fact the real problem is that my customer doesn't want to tell his manager that he choosed the server a little bit too quickly and I don't wan't his manager to think that we let him make his choice too quickly. So if I can find a proper way to use what he bought without buying anything else, everything will be perfect. I realize that these reasons aren't very good reasons, but I must do it like that. I would have prefered to have someone listening to me and thinking a little bit before making his decisions, but it is not the case so I must do with that. And anyway, the performances are not very important for this customer, what he wants is to have a reliable backup system and for that, TSM is a good solution I think.

Sorry, I used before some of these softwares and except the fact that they don't use tape-tape copies, they aren't from my point of view better solutions than TSM, even for small companies. What I saw with another software is that each time I was not in office for some times (2 or 3 weeks), when I came back, there had always been a problem which had made the backup stop. With TSM, I can leave the office and not look at it for a month, when I look back, everythings is ok, except for hardware failures. And the point is : as Tivoli did it for a part of the software, why don't they do it for the whole software ? I would like to know what is the use of a disk reclaim storage pool when you have a three drives library. So if they did it for main pools, why don't they make it for copy pools. And why isn't there a possibility to have a next storage pool for a copy pool ? which would allow me to make a backup of my storage pool to disk and then back on a copy tape. What make me angry is that I think that the main functionalities of TSM are exactly what I look for, and only for a few small functionnalities that would probably be easy to add and that wouldn't cause any problem to other users, I can't use it in a lot of cases. And you tell me that I should buy a low level software ? It's a little bit like if I told you that I like Mercedes except for the ash tray which I prefer on a Fiat and you respond me : Buy a Fiat ! but the Fiat has everything I prefer on the Mercedes, except the ash tray !

Unless there is some critical functionality that TSM has that nothing else does, using TSM with a single drive library is kind of a square-peg/round-hole solution. There are better solutions for environments of this scale, specifically solutions that don't use tape-tape copies as part of their base functionality. Grandfather-father-son schemed backup utilities would probably be better.

From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED]]On Behalf Of GUILLAUMONT Etienne I hope you will excuse me to be so direct but I think that you last answer is stupid, Actually, I won't excuse you, and there's no need to be insulting. did you ever look at the price of a single drive library compared to a three drive library ? Indeed I have. I install and configure them for a living. And I don't talk of the fact that most 3 drives libraries require the advanced library TSM feature which multiplies the price of TSM by 4 ! But I think this is why you talk of a BIG favour, it is because the price is BIG. If you compare the whole solution, you will see that the whole solution has a price multiplied bye 4 or more which makes it unaffordable for most companies. I guess it all comes down to what's more important--the cost of a proper library vs. the ability to dependably make multiple backups of your valuable data. I completely agree with you that a three drive (or at least two drives) library is far more practical with TSM but it is very expensive. In addition, what is the use of buying a 2 or 3 Tbytes library when you need only 200 or 300 Gbytes. You buy a smaller, scaled-down library. I stated earlier that single-drive libraries were pretty much worthless. I should have said that they were pretty much worthless when used with TSM. I saw in this list some people saying that TSM is only for big companies and that if you can't afford a 2 drives library, you should'nt buy TSM. I don't ever recall anyone on this mailing list claiming that TSM is only for big companies. Is TSM expensive? Yes. But if I want to run a high-end computer game, I don't go out a buy a cheap video card, either. I also disagree with that, TSM has some functionalities which make it usefull also for small companies (I had another storage software before and for example, I saw that with TSM, I could reduce the number of tapes to buy, and then to manage by 2 or 3) Indeed it has. I think it wouldn't be a lot of work for Tivoli just to add a few functionnalities which would allow small companies to use it with a single drive or with a small library. And just how do you propose to use a single drive to run space reclamation on copy pool tapes? (This was the original question for this thread.) Copy pool reclamation uses files from the primary tape pool, and you just can't access two tapes at a time with one drive. If you're going to use a single drive, you're either going to have to forgo copy pools, or live with the fact that you can't run reclaims on them
Re: Off site copy with one drive???
The only small things I would need to be able to use TSM with a single drive library is to have the ability of having a next storage pool on a copy pool, I must be possible to do as it is already done on a backup storage pool. And the ability of using a disk reclaim storage pool for offsite copy pool reclaim. My solutions would be the following : A backup pool on tape in the library 1 or more copy pools in a vault with only one or two empty tapes in the library. Each day, I backup on tape and make a copy on one of the copy pools, if an offsite tape is to be reclaimed, TSM copies the files in the disk reclaim pool from the backup pool and then switch tapes to write to the copy pool tapes Except the fact that if my drive goes down, I must wait until it is repaired (with a three drives library, you will still have this problem if the whole library goes down), the functionalities would be the same than with two tapes. Except for performances but everyone don't need performances in backup and restore. But everyone needs reliability in backups and TSM is very good for that. I agree with you that if there is no other possibility, it's better to buy and expensive library than having unreliable backups. But TSM requires very few modifications to be fully usable with a single drive library. Don't forget that most other softwares work perfectly with a single drive library, and some of them must probably be as good as TSM or not far from it. Excuse me for having been insulting but each time I hear There's no way to do it it upsets me. (And my english is not that good, I probably could have found a more adequate word than stupid) Etienne GUILLAUMONT e-mail : [EMAIL PROTECTED] RGB Technologie Parc d'Innovation, Batiment PYTHAGORE 11 Rue Jean SAPIDUS 67400 ILLKIRCH Tél : 03 90 40 60 60 Fax : 03 90 40 60 61 Mark StapletonTo: [EMAIL PROTECTED] stapleto@BERcc: BEE.COM Subject: Re: Off site copy with one drive???

Don't forget that many companies uses only a single drive on each server and if you talk to them of the price of TSM with advanced library and a 3 drives library, they laugh. Anyway, the cheapest configuration which I use without buying a BIG library and which is practical with TSM is to add an external drive which I use for the copy pool. You just need to have a drive which can contain at least the amount of data you backup each day. It is not a real problem that you have to change the copypool tapes each day as it is what everybody make usually, even with a library. The only thing which is a bit annoying is that I still didn't find a best way than creating a script which set all the copypool tapes to writeonly except the tape which is intended to be used. And I have to modify the script each time I change a tape which is full. But I must admit I still didn't understand very well how TSM manages the use of a single external drive. Sometimes, I can put any tape and everything is ok, and some other times, I put in an empty tape and TSM asks me for another. This is why I had to create this script. But I still didn't spend the time I should have to solve this problem.

Re: Data in offsite pool that is not in onsite pool
Hello, I had once such a problem and I found that one of my drive had had problems with cleaning and TSM was unable to read the onsite Volume. The problem is that TSM had put the unreadeable tape to unavailable status. I just had to issue a upd vol X acc=readw and evrything was ok. If this is your problem, you can try this and if it doesn't work, restore the damaged volume. This is exactly what copy storage pools are made for.

What I would do is look at the actlog and see what vols reclaimation isn't able to continue on, and then do a restore vol VOLSER preview=yes on that volume. Most of the volumes that will come up as being needed will be the ones that you see in the actlog now as being needed, but are offsite. We brought the tapes from offsite, checked them in, restored vol without the preview option, and then checked the offsite vols back out. It took something like 80 tapes to restore 5 onsite tapes with bad data. it was a lot of fun! -ed [EMAIL PROTECTED] 2002/09/03 08:57:30 AM Our offsite pool reclamation process is calling for tapes that are listed as being in the vault (and they actually are).

Re: missing volumes
Why don't you just check the volumes whose access is offsite and whose status is empty ? This is what I do. And to be sure that all volumes present in library are in an readwrite status, I just put all the volumes of the copypool in offsite state and then all the volumes of the libvol in readwrite state. For that, I use a Shell script which is below. The only thing which is special is that I only have private volumes and all the volumes of my copy pool have a name starting with 'COP' But I guess it wouldn't be very difficult to make a check on the libvol volumes to select the ones which belong to the copy pool #!/bin/ksh LIBVOLS=$(dsmadmc -id=admin -pa=admin select volume_name from libvolumes where volume_name like 'C%' | grep COP) TOTVOLS=$(dsmadmc -id=admin -pa=admin select volume_name from volumes where volume_name like 'C%' | grep COP) for VOL in $TOTVOLS do dsmadmc -id=admin -pa=admin upd vol $VOL acc=offsite done for VOL in $LIBVOLS do dsmadmc -id=admin -pa=admin upd vol $VOL acc=readw done Etienne GUILLAUMONT e-mail : [EMAIL PROTECTED] RGB Technologie Parc d'Innovation, Batiment PYTHAGORE 11 Rue Jean SAPIDUS 67400 ILLKIRCH Tél : 03 90 40 60 60 Fax : 03 90 40 60 61 Henrik WahlstedtTo: [EMAIL PROTECTED] shwl@STATOILcc: .COMSubject: missing volumes Sent by: ADSM: Dist Stor Manager [EMAIL PROTECTED] RIST.EDU 29/08/02 12:45 Please respond to ADSM: Dist Stor Manager Hello, I would like to know how to compare volume names in volumes and libvolumes with a select statement.

Backing up of different filespaces on diferent storagepools
Hello, I would like to know the best way to backup different filespaces on the same server on different storagepools. Do I have to define 2 nodes for the server containing the filespaces or is there another way to associate 2 management classes to a single server ?
