Managing Disk Devices

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

4. Verify that the new disk is configured into the system by entering the

following commands:

ioscan -fn -C disk

ftsmaint ls hw_path

hw_path is the hardware path to the disk. Confirm that the disk is present,

CLAIMED, and Online, and that device special files have been created for it in

the /dev/dsk and /dev/rdsk directories. (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.)

NOTE

Physically adding a disk does not configure it into a logical volume. See

the “Managing Disks Using the Logical Volume Manager (LVM)”

chapter in the Managing Systems and Workgroups (B2355-90157) and the

“Mirroring Data” chapter in the HP-UX Operating System: Fault Tolerant

System Administration (R1004H) for information about configuring a

new disk using the LVM.

Replacing a Broken Disk Drive

Use the following procedure to replace a broken disk drive:

1. Log in as root.

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

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 replaced a mirrored or nonmirrored LVM disk.

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.)
