Re: Problem with 3494 / 3590 drives only partly seen by library

Works here.  (same environment, but direct FC attached)
Maybe your SAN DG needs to have its scsi rescanned.  You could try delete
the drives under TSM, rmdev -dl under AIX, rescan at the SAN DG, cfgmgr,
define the drives under TSM, and try again?
