Disk Drive

This section explains how to replace a disk drive in a disk array that is under Sun™
StorEdge Volume Manager™ software administration (formerly known as Sun™
Enterprise Volume Manager™ software). Go to Appendix C if your disk array is
under Solstice DiskSuite™ administration.
Note – If you are installing a new disk drive, remove the disk drive spacer and then
go to Step 8.
The following is a summary of the steps for the disk replacement procedure:
Prepare the software on each host for disk replacement.
Use the luxadm remove_device command to remove the disk on each host.
Use the luxadm insert_device command to install the new disk on each host.
Notify the software of the new disk.
Note – For a disk in a multihost environment, the disk replacement procedure
should first be performed on the host that currently has ownership access to the
disk. Then the procedure can be performed in any order on the remaining host(s).
1. Identify all volumes or applications using the failed disk.
If the volumes are mirrored or RAID 5 protected, the disk can be replaced without
taking the volume down. Otherwise all I/O to the disk must be stopped using the
appropriate commands.
2. For disks under Sun StorEdge Volume Manager (volume manager) control, use the
vxdiskadm command to take the disk drive offline.
# vxdiskadm
Note – To replace a disk drive, choose option 4, "Remove a disk for replacement"
and then option 11, "Disable (offline) a disk device."
