Replacement Procedure: DS2300 Disk Drive, 18GB-36GB-72GB

You can add or replace disks to increase storage capacity or eliminate faults. (See Chapter 4 of the

HP StorageWorks Disk System 2300 User’s Guide

for troubleshooting procedures.)

Disks must be Ultra-3 SCSI (LVD) and 3.5 inches wide but can vary in capacity.

For current information about supported disks, consult an HP sales representative.

You do not need to turn off the disk system to replace a disk or filler.

Caution

Do not remove hot-pluggable components until you have the replacement parts and are ready to

install them. An empty slot will cause uneven cooling and eventual overheating.

Preparation (HP-UX 11.XX)

Removing or replacing a disk has consequences for the file systems and logical volumes located on the disk.

Before removing or replacing a disk, complete the appropriate system administration for your environment

and configuration.

Instructions for determining physical volume status and reducing and recreating mirrored extents follow. For

additional information, refer to your HP-UX guide,

How HP-UX Works: Concepts for the System

Administrator

.

The LVM commands in the following instructions assume the following:

??

All of the extents of the disk in use belong to mirrored logical volumes created with the strict (-s)

option.

??

The replacement disk is of the same or greater capacity as the disk being replaced.

The correct set of instructions depends on whether the mirrored volume is active and attached, or

unattached.

First, follow the instructions to determine the volume status; then follow the instructions to replace the volume

depending on whether the volume is attached or unattached.
