Unable to execute wide SCSI commands
Tape Library: Unable to execute wide SCSI commands. For example, the library
may respond to some, but not all SCSI commands. Typically indicates a bad
electrical connection on pins used for wide commands. Replace cables,
terminators, and devices located on the BUS where fault is located.
Data Protector Media Allocation Order
If receiving unexpected mount requests, or if it is confusing as to the order in
which Data Protector is using tapes in the tape library or media pools, the
following information should be helpful.
Solution
The sequence of media allocation is in the order of the following Data Protector
media sets:
1. Preallocated Media—Media named in the datalist device options
preallocation list. Preallocated media in “Poor” condition will not be used.
The pool policy can be Strict or Loose. This media set is not sorted.
Order of use: as specified in the datalist, provided that this will not break any
other rules such as those relating to protection and appendable media.
