We too did last weekend an upgrade from 3590B1A to 3590E1A and
everything worked like a charm:
Our Data:
OS AIX 4.3.2+
ADSM 3.1.2.42
Atape 4.6.2.0
atldd 4.0.1.0
3590 Microcode CA8E
3494 Microcode 522.08
Found exact information for move in README.SRV for 3.1.2.30:
- Using SMIT utility or manually, remove /dev/rmt0 device
example: rmdev -l 'rmt0' '-d;
- Using SMIT utility or manually, define the 3590E device
example: mkdev -c tape -t '3590' -s 'scsi' -p 'scsi0'
-w '0,0' -l 'rmt0';
- Run ADSM server (dsmserv);
- Issue ADSM command: UPDate DEVclass devclassname FORMAT=DRIVE
update devclass devclass_3590 FORMAT=DRIVE;
- Issue ADSM command: DELete DRive libname drivename
delete drive lib_3590 drive_3590;
- Issue ADSM command:
DEFine DRive libname drivename DEVIce=devicename
define drive lib_3590 drive_3590 device=/dev/rmt0;
- Update all previously written on 3590 drive volumes
to readonly mode
update volume volname access=readonly;
Hope this helps,
