Disk Replacement SVM

Hello,

Can someone advise the proper procedure for replacing a mirrored disk in SVM. I have checked the docs and various websites but the procedure seems to vary. This is what I would do...

1. Remove the db replicas from the bad disk.
2. Detach it from the mirror
3. Clear it with metaclear.
4. Replace the Disk
5. Copy the label from the good disk using prtvtoc and ftmhard
6. Create new db replicas
7. Create all the metadevices again then attach them which should start the resync?

Is this all necessary or can I just do a metareplace -e ?

I hope this is roughly right, What im not sure about is the need to use cfgadm to deconfig the failed disk then configure the new on back in, is this dependant on what hardware you are running?

Also, is a reboot required for any of this?

Many Thanks.

NAME
mkqdisk - Cluster Quorum Disk Utility WARNING
Use of this command can cause the cluster to malfunction. SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]] DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node. OPTIONS
-c device -l label Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough space to hold a UUID created with uuidgen(1). -f label Find the cluster quorum disk with the given label and display information about it. -L Display information on all accessible cluster quorum disks. -d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect. SEE ALSO
