CBR5884I ARA initialization failed: mode unavailable for volume volser.
Explanation
An I/O error has occurred on an optical disk drive. The drive returned a fault code of X'91'. This fault code is reported as a result of any read or write in Auto ReAllocate (ARA) mode after the cartridge initialization sequence failed to determine the ARA Orphan Table or Spares Area state for volume volser. Since OAM is not using ARA mode, this is likely to be a microcode error.
System action
The I/O operation is stopped.
Operator response
Notify the service representative.
