Re.:

MLNOMTL Volume does not reside in this Manual Tape Library.

and
MLNOTVR No TCDB TVR entry exists for this MTL volume.

Just to tie up the loose end, Peter informed me that there was some kind of 
typo in volume initialization.

Re: Virtual tape mount error

[Mike Baldwin]

Hi Peter,

The message IEC518I doc says: MLNOMTL Volume does not reside in this Manual 
Tape Library.

System programmer response
...System command D SMS,VOLUME(volser) will provide additional volume status. 

Programmer response
Report software error category to library subsystem administrator.

One of our customers reported this problem before:

Receive: IEC518I sfw err stat MLNOMTL 
...
I seem to have the MTL business working - had made an error 
defining the volume entries, and after I'd initialized the tapes, all
seemed fine. Thanks for your help.   
 
I had originally defined them using the following:   
 
CREATEVOLUMEENTRY (NAME(VMVS011) +   
   LIBRARYNAME(MTL3590) +
   STORAGEGROUP(MTL3590))
 
which actually gives a message, which I didn't notice, saying that the   
library name has been defaulted to SHELF, even though it's specified 
explicitly.  
 
When I changed it to:
 
CREATEVOLUMEENTRY (NAME(VMVS011) +   
   LIBRARYNAME(MTL3590) +
   LOCATION(LIBRARY) +   
   STORAGEGROUP(MTL3590))

the entries were correct.  Also, as I said, I made sure that all the
cartridges were initialized correctly.

EDG4020I
Explanation 
The specified volume cannot be used on this system because the volume   
prefix matches one or more REJECT prefixes defined for the installation.

It seems that RMM dislikes the volume serial that you've chosen, at least on 
this LPAR.
You could confirm with command RMM LC ALL, there may be something like:

Reject prefixes:  
Rack Prefix  Access type  
---  ---  
n*   NONE 

or you could check PARMLIB(EDGRMMxx) for REJECT commands.
BTW, IBM recommends converting REJECT to OPENRULE and PRTITION.

Some suggestions:
- Try running on a different LPAR that does not REJECT the volume serial prefix
- Update current LPAR EDGRMMxx to not REJECT your volume serial; recycle RMM
- Specify a different volume serial, since you're using BLP anyway; warn 
Operator

A totally different dance around RMM: Our partner used our TelTape for Windows
to MAP cartridges using SCSI/FC attached drives (No RMM on Windows!).
They had over 100,000 cartridges to map, though, and many platforms not just 
mainframe.
In particular, Map saves the Netbackup filenames, server names, creation dates 
in a spreadsheet.
Or if mainframe (SL), then DSN-17, creation date, etc.

"You do need a tape controller for physical tape. That's always been true"

Technically yes, although some (non-IBM) drives include a built-in controller.
Timothy, thank you for contributing that IBM considers TS7700 the new
tape control unit.  Otherwise we think IBM taketh away without THINKing.

Re: z/OS Data Set Encryption Now Generally Available

z/OS Data Set Encryption is a fantastic new feature, kudos to IBM, and I don't
mean to detract from its wonderfulness.

That's a good point, and I understand, if a new disk dataset is encrypted,
then copying it to tape will maintain encryption.  Very good, especially for 
HSM.
Mentioning 3390 makes the scope of support much clearer, thank you.

But...
The feature is called "Data Set Encryption", not "Disk Data Set Encryption",
so there is an expectation that it would (directly) apply to tape as well.
The FAQ "difference"s does not mention that this method is different
(from Encryption Facility) with respect to device type/class, i.e. 3390 yes, 
tape no.

There are many programs that write directly to device type 3490 (and 3590-1),
both of which can be virtual (not using TS11x0 hardware encryption).
Unknown whether they are copying data from disk, or not.
I looked at 10 medium-sized customer tape databases (RMM extract, etc.), and the
top 10 programs (other than HSM ADR* etc) were:
1  IEBGENER
2  DBUTLTY 
3  HASJES20
4  ICE*
5  NSX*
6  DSN*
7  IDCAMS  
8  SYNCSORT
9  FILEAID 
10 JHS*

and there are many others.
Tape data has moved from off-line, to near-line, to pretty close to on-line 
these days.
That is, it is very accessible, and I believe no less sensitive than data 
stored on disk.

Consider a job executing a program that writes a dataset, and the DSN resolves 
to a disk dataset.
The data could be encrypted - great!
In another job, same program but a different DSN that resolves to a tape 
dataset.
Not encrypted due to device type - not good.

It would be helpful to know if there is an intent to extend this feature to the 
tape device class,
or if customers need to differentiate between datasets written to disk 
(potentially
encrypted) and tape (needing a different encryption technique, or change to 
disk and
then backup to tape).
Also helpful would be support for EXCP access method.
Does IBM give any hints, Timothy?

Thank you!

Re: z/OS Data Set Encryption Now Generally Available

[Mike Baldwin]

Hi Timothy,

Thanks for this.

>BSAM, QSAM, and VSAM extended format data sets are all supported. 

The FAQ says "residing on disk", so datasets residing on tape (e.g. TS7700)
would not be supported.  (Even if accessed using BSAM/QSAM, and of course EXCP).
Is that correct, and do we expect it's a permanent restriction?

Re: OMVS Mass Reassign of File Owner

[Mike Baldwin]

Hi John,

Glad that worked for you.

I thought I'd add that there is a product.  It's called Superuser for z/OS,
and is mostly an ISPF application, although you can choose to run the generated 
commands in batch.
From the "Reports" menu, you would choose the "Free Search" option.
On the "Search Files" entry panel, you enter a Start Directory
(that directory and all of its subdirectories are searched),
an owner (UID) and/or group (GID),
and/or any optional attributes such as filename mask.
The "Query Result" panel displays the found directories and filenames.
You can choose "Global Change", and specify a new user (UID) and/or group (GID)
(permissions can also be changed).
The generated commands are presented, and you can choose to run them
either in batch, or 'online'.

Re: Sources for learing about state of the art Mainframe Virtual and physical tape?

[Mike Baldwin]

Hi Peter,

I hope you will be learning, not learing.   ;-)

Lizette provided a good list of options.
Additional virtual options include:
IBM TS7740, VTFM
Oracle VSM, VLE

Since the subject included physical tape,
IBM TS1140
Oracle T1D, 9840D

Russell's presentation is a good source.
Bear in mind that
it's 3 1/2 years old (maybe he has updated it since then).
So some things have changed, in particular
Bus-Tech was bought by EMC over 3 years ago.

HTH.
