Oracle HSM (SAM-QFS): How To Verify the Drive Order Configuration Is Correct for an ACSLS-Controlled Library (Doc ID 1005607.1)

Last updated on AUGUST 10, 2017

Applies to:

Oracle Hierarchical Storage Manager (HSM) and StorageTek QFS Software - Version 3.5 and later
All Platforms

Goal

Many library problems that occur, when archiving for the first time, are a result of drive ordering. The HSM (SAM-QFS) software and the library must be in synchronization, so care must be taken when defining the drives in the mcf file.

When the drive ordering is not in sync between the SAM software and the library, all kinds of unexpected failures can be seen, during both archiving (writing) and staging (reading) to /from the tape media because SAM will instruct the tape robotics to put a VSN into drive "A", thinking it's the drive with index "X"; once the library has mounted that VSN into drive "B" (because the order index is mismatched against what SAM has configured), SAM attempts to read drive "A", which might or might not have another tape media loaded.

Attention :
When the tape library is not ACSLS attached but direct attached
(via SAN, SCSI or direct attached cables), please consult the following document : How To Verify the Drive Order Configuration Is Correct for a Directly Attached Library (Doc ID 1006246.1)
