Customers can set device IDs which are user-friendly names. User-friendly device identifiers can only be set for devices supporting the SET DEVICE IDENTIFIER and REPORT DEVICE IDENTIFIER SCSI commands. In this case, the identifier resides in non-volatile memory on the device and can be queried by all systems accessing the device. The alias is stored locally in the system registry. Therefore it must be set on each HP-UX system accessing the device (such as a cluster).

scsimgr -f set_devid -D /dev/rdisk/disk0 "Engineering"
scsimgr: Device Identifier successfully setTo display the device identifier assigned to disk device disk0:
scsimgr get_devid -D /dev/rdisk/disk0
