Managing Disk Devices

HP-UX version 11.00.01 Configuring Disk Drives 4-5

b. To determine the mirror state of the logical volumes, enter

lvdisplay lv_name

lv_name is the path name (identified in step a). Check the field

Mirror copies for mirror information. Repeat for each logical volume.

4. Deallocate the logical volumes by entering

lvreduce [-m 0] lv_path pv_path

lv_path is the block device path name of the logical volume and pv_path is

the path name of the physical volume (the disk to be replaced). Use the -m 0

option if you replaced a mirrored disk; leave out this option if the disk was not

mirrored. Repeat this command for each logical volume.

NOTE

Because the disk is broken, you might see some error messages after

invoking lvreduce. You can ignore these error messages and proceed

to the next step.

5. Remove the disk from its volume group by entering

vgreduce vg_name pv_path

vg_name is the path name of the volume group (obtained in step 3) and

pv_path is the path name of the physical volume (the disk to be replaced).

6. Remove the disk drive and insert the new disk drive, following instructions

provided in the hardware documentation. See the HP-UX Operating System:

Continuum Series 400 Operation and Maintenance Guide (R001H), the HP-UX

Operating System: Continuum Series 400-CO Operation and Maintenance Guide

(R025H), or the HP-UX Operating System: Continuum Series 600 and 1200

Operation and Maintenance Guide (R024H) for instructions.

The green light on the disk will come on and its amber light will flash as the

disk drive goes through self-test and is brought online. When the drive is

online, the green light will go out.

7. Verify that the disk is operational by entering

ftsmaint ls hw_path

hw_path is the hardware path of the replaced drive. If the drive is not listed

as Online and its State listed as CLAIMED, contact the CAC.

8. Create a physical volume on the new disk by entering

pvcreate [-B] rpv_path

rpv_path is the character (raw) device file name for the new disk, for

example, /dev/rdsk/c0t1d0. Use the -B option if this is a boot disk.
