HP Evolution II DDS/DAT drives: UNIX, Linux and OpenVMS configuration guide 19
3 HP (OpenVMS) servers and workstations
NOTE: Only SCSI tape drives and autoloaders are supported on OpenVMS.
Determining attached devices
After connecting the tape drive to your system, boot OpenVMS and check for the presence of the
new tape device. Execute the following commands.
$ sho dev mk
Device Device Error Volume Free Trans Mnt
Name Status Count Label Blocks Count Cnt
MKA400: Online 0
 use this value in the next command line
$ sho dev MKA400/full
Magtape MKA400:, device type HP C7438A, is online, record-oriented
device, file-oriented device, available to cluster, error logging
is enabled, controller supports compaction (compaction disabled),
device supports fastskip (per_io).
Error count 0 Operations completed 222530
Owner process "" Owner UIC [1,4]
Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G:R,W
Reference count 0 Default buffer size 512
Density default Format Normal-11
Volume status: no-unload on dismount, beginning-of-tape, odd parity.
Configuring an autoloader on OpenVMS and MRU
1. Find the name of the changer device by executing:
$ mcr sysman io auto/log
If the DAT tape drive is at device ID mka400, the changer device will be gka401.
The parts of the device name are as follows:
2. Enter the following, replacing gka401 with the changer device file you found in step 1:
$ mcr sysman io connect gka401: /driver=sys$gkdriver.exe/noadapter
$ define/system mru_robot gka401
To maintain these changes across reboots, edit the sys$startup_vms.com file to include
these two lines.
