Maintenance and Service Guide

Replacing a disk drive

Disk drive hot swapping is supported under the circumstances described below.

Abide by the following rules related to disk drive removal and disk drive insertion

into HSG80 subsystems.

Note: If you submit the RUN CONFIG CLI command while a bad disk drive exists,

ACS skips the bad disk drive while running the RUN CONFIG command and reports

the following error:

DEVICE AT P1:T4:L0 failed initialization, Skipping

Device

Tip: Consider the following initialization and troubleshooting tips:

■ If you are initializing a disk, HP recommends that you initialize the disk without any

partitions prior to initially placing it into use. If you are adding a new disk to an

array, and it is presented to a Microsoft Windows or Windows NT host, add the

new disk to the array first, and then initialize the disk using the INITIALIZE

container-name DESTROY_MBR CLI command. Doing this prevents the

creation of more than one partition on a disk. Refer to the

HP StorageWorks

HSG60 and HSG80 Array Controller and Array Controller Software Command

Line Interface Reference Guide

for additional information about the INIT DEVIC

DESTROY_MBR CLI command.

■ If you have a disk that was initialized at the container or device level using the

SAVE_CONFIGUATION switch, you can submit the ASSIGN storageset

LUN_WWID=xx CLI command to remove the SAVE_CONFIGURATION attribute

and reassign the unit its original WWID.

■ If you need specific information regarding disks in a subsystem, you can submit the

SHOW DEVICE_INFO ALL or SHOW DEVICE_INFO Dxxxx

FMU

command.

This command provides details regarding the disk port number, target number,

model number, firmware version, serial number, device flags, metadata version,

and SAVE_CONFIGURATION status. Refer to the

HP StorageWorks HSG60 and

HSG80 Array Controller and Array Controller Software Troubleshooting Guide

for

additional information about the SHOW DEVICE_INFO ALL and SHOW

DEVICE_INFO Dxxxx

FMU

commands.
