Managing Disk Devices

HP-UX version 11.00.01 Configuring Disk Drives 4-11

13. If the newly located disk is not the root disk, you can mount it by entering

mount -a

If the newly located disk is the root disk, it has been mounted already by other

means.

14. Update any software application configurations that use the relocated disk

drive to make sure they use the new device files. See your software application

documentation for specific instructions.

For more information on the use of mirroring and associating and dissociating

disks with their volume groups, see the Managing Systems and

Workgroups (B2355-90157) and the “Mirroring Data” chapter in the HP-UX

Operating System: Fault Tolerant System Administration (R1004H).

Deleting a Disk Drive

Use the following procedure to permanently remove a disk drive from your

system:

1. Log in as root.

2. Back up the files on the disk drive to be deleted. See the Managing Systems and

Workgroups (B2355-90157) for instructions on how to back up data.

3. Display the contents of the active volume group(s), by entering

vgdisplay -v

Identify any logical volumes currently straddling the disk being moved and

another disk. Logical volume path names are in the LV Name fields. (The

volume group path name is in the VG Name field.)

4. Determine the mirror state of the logical volumes by entering

lvdisplay lv_name

lv_name is the path name (identified in step 3). Look in the Mirror copies

field for mirror information. Repeat for each logical volume.

5. If you find any straddled volumes in step 3, remove the logical volume(s).

– If the volume is not mirrored, enter

lvremove lv_path

lv_path is the block device path name of the logical volume.

– If the volume is mirrored, remove the mirroring by entering

lvreduce -m 0 lv_path

Repeat for all straddled volumes.
