Deleting an orphaned volume

[joshmo]

Hi,

I've recently upgraded the tape libraries on our TSM instalation as part of this I migrated the storage pools associated with the old tape library to new storagepools using the new tape library device class.

Have complete this operation I am left with one empty volume that is part of one of the old storage pools that I can't delete.

I've tried the folowing:

1: del volume hf6454l4 discard=yes

This fails with an error saying that the volume state is mountablenotinlib.

2: Tried the move media command to update the state above.

move media hf6454l4 stg=* wherestate=mountablenotinlib

This also fails with an error that the old library is not defined (I've already deleted the old library, may be a bad move in hindsight!)

Anyone have any other ways I can delete this volume reference. BTW this is stopping me from deleting the old storagepool this volume is in aswell.

Thanks!

Hi,

try to update the access to "readwrite"
upd vol HF6454L4 acc=readw
and then try to delete it again (in case it is empty it may be deleted immediately you change the access mode)
Show us the complete actlog part where you change the access and try to delete it - so we can see all the errors.
Attaching "q vol HF6454L4 f=d" would be helpful as well.

Hope it helps

Harry

When trying to delete.....

HF6454L4 (SESSION: 69890)

So try to change the volume state to mountableinlib by moving media...

Hi,

if I understand it correctly there is a stgpool VIRTUALVOLSOLD (is it primary or copy?) and it is defined using (old) device class HHH_LTO4. This device class does not point to any library now (as you said you have deleted it).
In that case it may be the root of the problem as the MOVE MEDIA does not process volumes in stgpools with no automated library

STGpool (Required)
Specifies the name of the sequential access primary or copy storage
pool that is used to select the volumes for processing. You can use a
wildcard character to specify the name. All matching storage pools
are processed. If the storage pool specified is not managed by an
automated library, no volumes are processed.

So I would try to update the old devclass with the new library (does not matter - ANY library should do the trick) and then use MOVE MEDIA again.

Really not sure if it helps - but seems we cannot break it more

Excellent idea...

Still didn't work tho.... Does the tape have to be in the library for this to work?

ANR0609I MOVE MEDIA started as process 1060. (SESSION:
71427, PROCESS: 1060)
ANR0610I MOVE MEDIA started by ADMIN as process 1060.
(SESSION: 71427, PROCESS: 1060)
ANR6682I MOVE MEDIA command ended: 0 volumes processed.
(SESSION: 71427, PROCESS: 1060)
ANR6691E MOVE MEDIA: No match is found for this move.
(SESSION: 71427, PROCESS: 1060)
ANR0611I MOVE MEDIA started by ADMIN as process 1060 has
ended. (SESSION: 71427, PROCESS: 1060)
ANR0985I Process 1060 for MOVE MEDIA running in the
BACKGROUND completed with completion state SUCCESS at
08:03:04. (SESSION: 71427, PROCESS: 1060)

Hi,

do not know - you may try it (checking the tape back in the library - the new one).
What about running
move media hf6454l4 stg=virtualvolsold
now, when the library is defined ....
If it does not help, try to check the tape in the library ... if possible.
