Re: What happens in HSM when I change a Management Class

[Michael Watkins]

Even though virtual tapes are essentially tape images on DASD, if a virtual 
tape dataset is allocated to a job or user, another dataset on the same virtual 
tape volume cannot be mounted elsewhere for use by another job or user. 
However, many virtual tape systems allow the size of each tape to be the size 
of the dataset being written to tape. Unless you're constrained by the number 
of tape volumes, why not put each dataset on its own tape? There is no wasted 
space, as there would be on a physical tape. Recycles then become unnecessary.

With the relatively fast response of virtual tape, the recycle threshold can be 
set fairly high.
I recycled daily. Assuming sufficient number of drives, it won't interfere with 
recall unless coincidentally actively recycling the dataset requested by the 
recall.

Re: What happens in HSM when I change a Management Class

[Paul Feller]

Gadi, Mike has a good point.  Doing HSM tape recycles could help free up any 
tapes with a low number of datasets on them.  This is true for migration tapes 
and backup tapes.  Be warned that if you don't do tape recycles on a scheduled 
basis the process could possibly run for a long time.  As an example, I think 
that could then impact HSM process of recalls from tape.  I believe the place I 
last worked at did tape recycles every day.

Also, I should have mentioned the information I pasted in my earlier reply came 
from the "DFSMSdfp Storage Administration" manual for z/OS 2.5.  It can be 
found in "Chapter 8. Defining management classes".

You should be recycling tapes with a low percent of active datasets.
This copies the remaining active datasets to a new tape then marking this on as 
inactive.  You can manually issue a recycle command against a specific volume.

SMP/E can't find APAR

[Pommier, Rex]

Hello list,

I'm apparently having a senior moment.  I'm having trouble running an apply 
check on my 2.4 system with a missing shell script that exists.  In researching 
it, I found a similar situation and as part of it I found this on IBM's web 
site:

SMP/E APAR IO27985 has been created to address this issue.

I can't find hide nor hair of this APAR, except in the document that says to go 
look at it (of course without a link).  Any thoughts as to what/where I should 
look?  I looked for SMPE APAR 27985 without the letters.  

TIA for helping unrattled this old brain.

Rex

Re: Rexx numeric digits and scientific notation question

[Charles Mills]

And the answer is ... "The three numeric settings are automatically saved 
across internal and external subroutine and function calls."

I was setting numeric digits in an initialization subroutine, so Rexx helpfully 
unset it on return from initialization. I thought I had done it that way before 
but I guess I have not.

Putting in a SAY for DIGITS() showed that it was 9, and I tracked it down from 
there.

Thanks all for your patience and suggestions.

Re: What happens in HSM when I change a Management Class

[Gadi Ben-Avi]

Hi Paul,
Thanks for your detailed explanation.

I would like to delete extra copies of backups, backups that have been on HSM 
for more than a specified number of days, and as a result of that, tapes that 
become empty will be deleted.

The end result would be that every backed-up dataset that still exists could 
have more than one backup, and datasets that do not exist anymore would have 
only one backup.

Gadi, I have to ask.  Are trying to delete backups of individual datasets or
the actual tapes created during dataset backup processing?

If you are trying to manage the actual backups of individual datasets, have
you looked at the different management classes used for the datasets?

The following fields in the management class affect backups taken for an
individual dataset.

Retain Days Only Backup Ver:
 Indicates how many days to keep the most recent backup version of a deleted
data set, starting from the day DFSMShsm detects it has been deleted. This
attribute applies only when a data set no longer exists on primary (level 0)
or migrated (levels 1 and 2) storage. The default is 60. This field does not
apply to objects. Backup copies of objects are not retained when the
original object is deleted.

Retain Days Extra Backup Vers:
 Indicates how many days to keep backup versions other than the most recent
one, starting from the day backups were created. It applies only when more
than one backup version exists, and when a data set has low activity. This
attribute applies whether the data set has been deleted or not. The default
is 30. The number of extra versions is the number of backup versions minus
one. If you specify 1 for Number of Backup Vers, there are no extra
versions. For example, if you specify 3 for Number of Backup Vers (Data Set
Deleted), the number of "extra" versions for deleted data sets is 2. These 2
versions are managed according to the Retain Days Extra Backup Vers
attribute. Any other versions that may have existed when the data set was
deleted will be deleted the next time EXPIREBV is processed.

Number of Backup Vers:
 Specifies the maximum number of backup versions to retain for a data set.
The default is 2 if the data set still exists and 1 if it has been deleted.
 Creating a new backup version when the number of backup versions already
equals the value specified for the appropriate Number of Backup Vers
attribute (Data Set Exists) causes the oldest version of the appropriate
type to be deleted.
 The number of backup versions is used to determine whether OAM should write
one or two backup copies of the objects, when you activate the
SECONDBACKUPGROUP function for objects using SETOSMC in the CBROAMxx member
of PARMLIB. If the number of backup versions is greater than 1 and AUTO
BACKUP is Y, OAM will create two backup copies. When the original object is
expired or deleted, all backup copies are also deleted.

What happens in HSM when I change a Management Class

[Gadi Ben-Avi]

Hi
when reviewing our HSM configuration we found that the management class used 
for all SMS backups says:

Expire after Days Non-usage . . NOLIMIT (1 to 93000 or NOLIMIT)
Expire after Date/Days . . . . . NOLIMIT (0 to 93000, /mm/dd or
NOLIMIT)

Retention Limit . . . . . . . . . NOLIMIT (0 to 93000 or NOLIMIT)

As I understand it, this means that backups will remain forever.

If I change the values, will HSM start deleting backups?
Will it happen immediately, during nightly processing or do I have to tell HSM 
to do it?
