Error description
Volume mounts in a tape library which has a large number of drives may take a long period of time. This problem is most common in virtual tape libraries with more than 100 tape drives. - The time delay will be between the start of a client session, library sharing session, or any other operation which requires a volume mount until the volume is actually mounted: - ANR8337I LTO volume V00003L3 mounted in drive DRIVE1 (/dev/rmt192) - Note: The fix for this problem is for a specific condition related to tape drive selection performance. There are other possible problems that can affect volume mount performance which are not related to Tivoli Storage Manager server function. Tivoli Storage Manager Versions Affected: 5.4, 5.5, and 6.1 on all platforms Initial Impact: Medium Additional Keywords: TSM VTL
Local fix
Define 80 or fewer tape drives in the Tivoli Storage Manager library. If necessary, create multiple libraries with up to 80 drives until a fix is available.
