Just ran an microcode update out of the web-based system manager and needed two updates. One on my tape drive (rmt0) and the other on my raid card. The card worked perfect, but the tape drive one failed? Now I can no longer see my tape drive.
lsdec -Cc tape
rmt0 Defined 04-08-00-0,0 LVD SCSI Tape Drive
rmt1 Available 06-08-00-2,0 Other SCSI Tape Drive
Is there a way to undo the microcode on that tape drive?
The internal tape drive is a VXA 320
The server is a pseries model 520
Any help would be great.. Many, many thanks in advance.
