Verification on OpenVMS¶

Boot OpenVMS and execute the appropriate command to see the devices used by the system.

To list the disk devices, issue SHOW DEVICES DK.
To list the controller devices, issue SHOW DEVICES PK.

For example:

$ SHOW DEVICES DK

Device                  Device           Error   Volume          Free  Trans Mnt
 Name                   Status           Count    Label         Blocks Count Cnt

DKA200:                 Online               0

$ SHOW DEVICES PK

Device                  Device           Error
 Name                   Status           Count
PKB0:                   Online               0
PKC0:                   Online               0
PKD0:                   Online               0
PKE0:                   Online               0
PKA0:                   Online               0

Note the unit number in the device names. It corresponds to the unit value in the XML configuration of your disk device. For the SATA disk devices, the unit number is converted to the nnn format, whereas for the Virtio-SCSI devices, it strictly corresponds to the unit number.

For example, 500 in DKD500: is the unit number in the nnn format specified in the XML configuration as follows:

<address type="drive" controller="3" bus="0" target="0" unit="5"/>

Execute the SHOW DEVICES device-name /FULL command to view the details on a particular device.
