Hi All ,

I have windows TSM sever where there are several drives and I need to understand where my data is being backed up . I have 2 almost full drives with identical space values on them . Also I have one more drive which also contains backed up data but i cannot identify from the > q stgpool command which pool is using which drive and why do I have that additional drive .

This is my qstgpool output . The thing is backups are failing with space issue and I am not sure if I can use the 19TB on the M: drive ( see pic above )

If you run "q devc filedev f=d" you will should see that your APP_DATA pool is using both of your K: and L: drives. This storage pool is full.

Output of "q stg app_data f=d" would be useful to see how much space can be reclaimed from there. It does look like you need more disk.

Any reason you are not using container pools?

Can you tell how can I use container pools ? How will it help me ? Also im unsure about the M drive . It has 19tb free and holds some of the backups . Can I reduce that and use it on K and L drives ?

Ok. K, L and M drives are used for your APP_DATA, APP_LOGS and OS_FILES storage pools. You have more space on disk than has been allocated to the storage pools. 87.3 TB disk is available but just under 68TB is usable by the storage pools.

From here I would increase the maxscratch for the APP_DATA storage pool by 380. "upd stg APP_DATA maxscr=<new_figure>"

After that, it would be best to run some reclaimation for the APP_DATA pool. That will clean up any volumes which it hasn't been able to reclaim as well as to help distribute the data across the K,L and M drives.

As for using container pools, that is something you can look at later. You will need the database to be on SSD disk and you will need more diskspace to do the conversion. The advantages are in deduplication and compression.

I notice all of your tape pools are showing as 0% utilized. Do you have any data on tape yet? Is this a new setup?

Once you have space in your FILE_TAPE_POOL the migration job should kick off automatically move data from the FS_DISK_POOL to FILE_TAPE_POOL.

You really need those scratch tapes. If you can't wait, you could allocate space to FS_DISK_POOL while you wait for the tapes to arrive. Or redirect the data to where you do have space although with all the separation that is setup here, I don't imagine that is an option.

The VE_DISK_POOL is close to having the same issue. It should also start migrating data to VE_TAPE_POOL with some scratch tapes.

How long before the scratch tapes arrive? Anyway to get these faster?

I don't really want to talk you through hacking up your config when scratch tapes should fix it.

Output from the following two queries would give more info on your tape usage.

SELECT volumes.stgpool_name, count(*) as "Number of Tapes" FROM volumes, libvolumes WHERE volumes.volume_name=libvolumes.volume_name GROUP BY stgpool_name

select library_name, count(*) as volumes, status, mediatype from libvolumes group by status,mediatype,library_name

Ok, it would be worth looking at the tapes and seeing how full they are. Do you have a lot of tapes with low utilization, lots in filling state? Commands below will help.

q vol stg=file_tape_pool

q vol stg=tdp_tape_pool

q vol stg=ve_tape_pool

Do you know if reclaimation is running? Are you sending tapes offsite and regularly receiving tape back onsite again?

yes , Reclaimination is running and daily activity we are sending only copy pool full tapes to offsite.Not sure we an send tape pool full tapes as well..
Need to know what is the use of keeping tape pool full tapes at onsite apart from restoration..
FRom one month am sending copy pool full tapes to offsite and alternate days i used to request for vault retrieve since it was showing in q drm..Now in drm i can tapes raraely

yesterday i tried movedata for onsite tapes with low utilization and got only one tape..

Ok. Your Full primary pool tapes really need to stay onsite in your library. These are used to do offsite reclaimation and things will get in a mess fast if you remove these from the library. However it looks like reclaimation may not be running against these pools as there are a number of Full tapes with low utilization.

Try running some reclaimation against your TDP_TAPE_POOL storage pool and you should be able to free up some tapes fast. I would use the following command.

reclaim stg TDP_TAPE_POOL th=60 du=180

This will run reclaimation for 3 hours against this pool and you should be able free up 4 or 5 tapes quite quickly. You will want to avoid running this while the backup or expiration is running and check you have available tape drives - probably just two required.
