How to change SMS

[John Mattson]

I just want to thank Lizette Kohler for the clear, concise yet detailed,
and patient answers.  I read thru this thread just to refresh myself on how
SMS works, and learned several things along the way. Many thanks for the
good answers.

Thanks again, Lizette, I had just read this in the IDCAMS manual as your
note popped in. I think I have it...

Thanks to all who answered, and have a great weekend!

Adding additional volumes so the file can expand and use them is 
easy. The hard part is to remove them again once they are no longer 
needed. This involves backing up the expanded file (assuming that it 
has been trimmed to remove the extra records) and deleting it. You 
then remove the extra volumes, redefine the file (now using only 3 
volumes) and restoring the backup.

Re: How to change SMS

[Bill Ashton]

OK, this is some education for me...I saw the count in the Dataclass and
thought I would have to only increase that. I will make sure the Dataclass
has the right count of vols, and will also be sure the SMS group has those
specific volumes defined.

Now to be sure I have the command right, since I have 3 vols, and am adding
3 vols, I would do ALTER dsn AVOL(* * *), right? The file will be deleted
at end of January, and a new one created, so I can do that after I take out
those 3 extra vols.

Thanks Lizette and everyone - I will let you know if I have further
questions.

How to change SMS

[Bill Ashton]

Hi friends! One of our users is working with a file that is currently
defined to a special Dataclass with 3 volumes (it is pretty full already).
They want to test an end-of-year process that will add a lot of data to
this file, and I would like to add another 3 volumes temporarily to this
class.

Can I just add the vols to the SMS dataclass, and the file will
automatically expand when she fills the 3 it had when defined, or would I
need to back it up and reallocate it again to pick up the new volumes?

She is the only user of this Dataclass, and this is only temporary (until
end of January). So I would need to know how to add the vols now, and then
back them out again in 3 months.

Thanks for your advice.

Is your data set in an SMS pool?

Or are these non SMS volumes?

Re: How to change SMS

The file is currently on 3 volumes that are SMS managed in a Dataclass that
has 3 volumes. We want to add 3 more volumes to this Dataclass and have the
file automatically pick them up. I will look at the ALTER AddVolumes...

Re: How to change SMS

[Lizette Koehler]

So,
You will need to add more volumes to the SMS Pool
Then go to the DATA Class and ensure you are not setting things like Volume 
Count or Dyna volume count to a number less then what you are providing your 
user.

And ALTER dsn VOL(* * * * * ) however many stars to reflect the number of 
volumes.
Also, do a LISTC ENT(dsn) ALL and see what the candidates look like before you 
make changes.

Also, remember that when the files allocate the new volume, You may wish to 
place them in QUINEW or something similar so you can get them back. Or is the 
user able to delete the file when you want the volumes back.

I am familiar with SMS storage groups.  I am not familiar with
dataclas that point to specific volumes without a storage group.
Please give me an example.

Re: How to change SMS

[Lizette Koehler]

As far as I know, the DATACLAS does not point to volumes.  Just number of 
volumes can be placed in the Dataclas.

A storage group could be set in the ACS code based on the Dataclas, maybe.  

But the environment might just be using the data class to set attributes of the 
file, and the use NON SMS volumes - i.e not using SMS POOLS.

Re: How to change SMS

[Lizette Koehler]

Remember

ADDVOLUMES(volser [ volser])
This provides the volumes that are to be added to the list of candidate 
volumes. You can use ALTER ADDVOLUMES to add candidate volumes to non-managed 
VSAM data sets and SMS-managed VSAM, non-VSAM, and generation data sets (GDS). 
Only nonspecific volumes can be added to SMS-managed, non-VSAM data sets and 
GDS data sets. If an ALTER ADDVOLUMES is done to a data set already opened and 
allocated, the data set must be closed, unallocated, reallocated, and reopened 
before VSAM can extend onto the newly added candidate volume. Adding a 
nonexistent volume to the list can result in an error when the data set is 
extended. Ensure that the volume exists and is online before attempting to 
extend the data set.

Restriction: This does not work with non-SMS non-VSAM.

SMS might not use candidate volumes for which you request specific volsers with 
the ADDVOLUMES parameter. Sometimes a user-specified volser for an SMS-managed 
data set results in an error. To avoid candidate-volume problems with SMS, you 
can have SMS choose the volser used for a candidate volume. To do this, you can 
code an * for each volser that you request with the ADDVOLUMES parameter. If, 
however, you request both specified and unspecified volsers in the same 
command, you must enter the specified volsers first in command syntax. The 
system does not allocate space on candidate volumes until VSAM extends to the 
candidate volume. This includes SMS-managed data sets with Guaranteed Space.
