Replacing a Disk Drive
NOTE: Sometimes using the diskinfo and ioscan commands will produce cached data. To
resolve this, these commands should be run when the disk drive is removed.
1. Before installing the disk drive, enter the following command:
#diskinfo -v /dev/rdsk/cxtxdx
2. Enter the following command:
#ioscan -f
The response message after running this command is:
NO_HW
3. Be sure the front locking latch is open, then position the disk drive in the chassis.
4. Slide the disk drive into the chassis. Use a slow firm pressure to properly seat the connection.
5. Depress the front locking latch to secure the disk drive in the chassis.
6. Spin up the disk by entering one of the following commands:
#diskinfo -v /dev/rdsk/cxtxdx
#ioscan -f
#pvcreate
#vgcfgrestore
