Disk drive loop ID
The EMU assigns a loop ID to each disk drive based on the enclosure ID and bay in which the disk is
installed. HP-UX stores the loop ID and WWN of each disk, and uses them to authenticate the disk.
Verifying the installation
Use IOSCAN to verify that the S/W state of the disks is CLAIMED.
Adding drives to an existing DS2500
You can add disk drives to an existing DS2500 without interrupting enclosure operation.
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper antistatic protection as described in the
