Enter the following command to allow HP-UX to ignore the disk authentication for the replacement disk.
fcmsutil /dev/device_file replace_dsk –l disk_loop_ID
For example, if you are replacing the disk drive installed in bay 5 in an enclosure with an ID 2
attached to HBA td1, enter:
fcmsutil /dev/td1 replace_dsk -l 4B
IMPORTANT:
You must run the fcmsutil replace_dsk command on all HBAs that can access the disk drive.
CAUTION:
Spinning media can make the disk drive difficult to handle. To avoid damaging the disk drive, wait
approximately 30 seconds for the media to stop rotating before removing the drive from the enclosure.
To remove a disk drive:
1. Push the ejector button ( Figure 34 -1) and pull the release lever ( Figure 34 -2) down to the full
open position.
