Be wary of this... I had been told the same thing, and the
'latest-and-greatest' microcode didn't help a bit... Please let me know if
you have a different experience....

// Hi everyone...
// I and my IBM CE have been pulling our hair out on this one for almost a
// week...
//
// Whenever my 3494lib w/ 2x 3590 B1A drives mounts a tape (to do a
// migration, for example), it shortly produces a WRITE error (errorno=78),
// and marks the tape 'read-only'.  I'm running ADSM 3.1.2.40 on an H70
// running AIX 4.3.2 The atape, atldd, and 3590 microcode are to current
// levels.
//
// This problem started as intermittent on one drive, and now has progressed
// to the point where I can't write anything to tape anymore on either drive.
//
// We have tried replacing the 18m SCSI cables, re-routing the SCSI cables,
// replacing both SCSI adapters, both terminators, and both 3590 card packs,
// all with no change in results.
//
// IBM hardware support says it's a software problem, ADSM support says it's
// a hardware problem... Anyone have any ideas?  I'm sweating big time
// because I'll run out of disk space upon which to do my backups soon
// if I can't move the data off to tape! :-(
//
// Thanks in advance!
