Sun Solaris Volume Manager (SVM) - Version 11.9.0 to 11.10.0 [Release 11.0] Oracle Solaris on SPARC (64-bit) Oracle Solaris on SPARC (32-bit) Oracle Solaris on x86-64 (64-bit) Oracle Solaris on x86 (32-bit)
The most commonly replaced hardware in any computer system is the disk drive. A failed disk will trigger many faults, by many monitoring utilities. Correct interpretation of these utilities is critically important to verify the following:
The disk is actually failed and needs to be replaced.
The correct location of the drive.
What needs to be done prior to the replacement.
What the actual replacement procedure will be.
In this article, we discuss some approaches to disk failures. Included are the internal disk drive (where the disk is resident inside the server) as well as externally-attached JBODs (just a bunch of disks).
This document is NOT intended for any disk being managed by a hardware RAID controller, either internal or external to the server.
All subsequent references to volume management software is for Solaris Volume Manager. This article does not discuss the volume management features of ZFS.
