a quick question:
I have one free disk plugged in the SAN Storage. It is not part of any array or hotspare coverage ( I have removed it from hotspare coverage -- )
Can I just remove the disk while the SAN is powered on and plugged into the failed disk ?
or
Do I need to shutdown the SAN Storage and remove the disk ?
--------------------
SOLUTION:
1) You can remove / unplug an ununsed powered Disk from the SAN STORAGE and use it in place of failed disk without powering off or anything
2) You can make the HOTSPARE a permanent disk provided this option is supported by the firmware level and software of DS4000

To summarize the problem: The "IBM FastT Storage Manager Client v8" shows that our Disk Farm is arranged into 6 logical drives each in a RAID 5 configuration. This software also shows that 5 of the 6 logical drives (from Disk Farm) are in a error state: "Failed Logical Drive - Drive Failure".... (1 Reply)

mkqdisk
mkqdisk(8) Quorum Disk Management mkqdisk(8)
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.
