Managing Disk Devices

4-6 Peripherals Configuration (R1001H) HP-UX version 11.00.01

9. Add the physical volume to the volume group by entering

vgextend vg_name pv_path

vg_name is the volume group name and pv_path is the block device file

name, for example, /dev/dsk/c0t1d0.

10. Do one of the following:

a. If you replaced a mirrored disk, reestablish the volume mirror by entering

lvextend -m 1 vg_name pv_path

Repeat for each logical volume.

b. If you replaced a nonmirrored disk, restore the missing data from your

backup archives (if available). See the Managing Systems and

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

11. Restore any volumes that were disabled by the failure. See the Managing

Systems and Workgroups (B2355-90157) for more information.

Replacing an Online Disk Drive

Use the following procedure to replace an online disk drive:

1. Log in as root.

2. Determine the location and state of the disk you are replacing by entering the

following commands:

ioscan -fn -C disk

ftsmaint ls hw_path

hw_path is the hardware path to the disk. Check the H/W Path, State, and

Status columns. See the “Administering Fault Tolerant Hardware” chapter

in the HP-UX Operating System: Fault Tolerant System Administration (R1004H)

for a description of the possible states. (There is substantial overlap between

the ftsmaint and ioscan commands, but the ftsmaint command does not

include the device file names and the ioscan command does not include the

Status information.)

3. Determine whether you are replacing a mirrored or nonmirrored LVM disk as

follows:

a. To determine the volume paths, enter

vgdisplay -v

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

path name is in the VG Name field.)
