Maintaining Disk Modules; Identifying And Verifying A Failed Disk Module - Silicon Graphics CHALLENGE RAID Owner's Manual

Identifying and Verifying a Failed Disk Module

Chapter 5

Maintaining Disk Modules

This chapter describes
• identifying and verifying a failed disk module
• setting up the workplace
• replacing a disk module
• installing an add-on disk module array
If you have determined that a module has failed by examining the cabinet
fault light or by using the raid5 getdisk or raid5 getcrus command, as
explained in Chapter 3 in this guide, you can replace the defective module
and rebuild your data without powering off the CHALLENGE RAID
storage system or interrupting user applications.
Caution: Removing the wrong drive module can introduce an additional
fault that shuts down the physical disk containing the failed module. Before
removing a disk module, verify that the suspected module has actually
failed.
