[ADSM-L] Virtual Volumes & DB Backup
2007-11-14 17:26:48
I have two TSM 5.4 servers using SATA drives as their targets. (They are named
TSM3 and TSM4) I do not have any tape drives or libraries set up.
I want to backup the database on TSM3 to TSM4 and vice versa. (As described in
an operation suggested in IBM TSM for Linux: Administrator's Guide, ver 5.3,
pages 602-607.)
However, I get this error:
ANR0984I Process 91 for DATABASE BACKUP started in the BACKGROUND at 03:47:08
PM.
ANR2280I Full database backup started as process 91.
ANR1404W Scratch volume mount request denied - mount failed.
ANR4578E Database backup/restore terminated - required volume was not mounted.
ANR0985I Process 91 for DATABASE BACKUP running in the BACKGROUND completed
with completion state FAILURE at 03:47:09 PM.
My strategy was to set up source and target servers for virtual volumes. When I
defined the storage pool on the target server I specified the devclass as DISK.
As in " define stgpool sourcepool disk". However, on the source server the
devclass "targetclass" seems to want a sequential device. I am guessing that
this is why it seems to be attempting to mount a scratch volume.
Device Class Name: TARGETCLASS
Device Access Strategy: Sequential
Storage Pool Count: 0
Device Type: SERVER
I have not found a way to update the targetclass device from "sequential" to
"random" .
Is this the best way to achieve my goal?
Thanks,
Rob
