a particular caveat. In the table, “O” indicates an open caveat and “R” indicates a resolved caveat.
Resolved Caveats
• CSCtj47693
Symptom: When the SME Tape feature is in use, the performance of the IBM LT03 device is lower
than when SME Tape is not in use.
Workaround: This issue is resolved.
• CSCtj56122
Symptom: The IPS processor does not compact IO packets whose compressed length is 256.
Workaround: This issue is resolved.
• CSCtj87140
Symptom: IOA does not work correctly for an IBM TSM backup application system that uses the
IBM A tape driver to communicate with an IBM LTO-5 drive. When IOA is introduced, the backup
fails. The underlying reason is that a vendor-specific command is sent by the driver to the LTO-5
tape drive and IOA does not recognize the command.
Workaround: This issue is resolved.
