Replacing a disk drive
Before you begin
Always use proper antistatic protection as described in the documentation that shipped with your system.
Do not remove more than one disk drive or drive blank from an operating DS2500. Doing so impacts air
fl
ow of the enclosure, and may cause data loss.
HP recommends installing a disk of equal or greater capacity, or a drive blank, as soon as possible.
Prevent possible data loss by verifying that the disk to be removed is in a failed state.
IMPORTANT:
When the system boots, HP-UX retrieves the loop ID and WWN of each disk and stores the information
for disk authentication. When you replace a disk drive, the authentication fails because the WWN has
changed. You must use
fcmsutil
to instruct the FC driver to ignore the authentication.
Removing a disk drive
Record the loop ID of the disk drive to be replaced. Use
Table 13
to determine the AL-PA and loop ID
based on the enclosure ID and Li setting for the bay in which the disk drive resides.
