How to Delete a LUN
Use this procedure to delete one or more LUNs. You might need to delete a LUN to free up or
reallocate resources, or to use the disks for other purposes. See the
Sun StorEdge RAID Manager
Release Notes
for the latest information about LUN administration.
This procedure relies on the following prerequisites and assumptions.
■
All data on the LUN that you delete will be removed.
■
You are not deleting LUN 0.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most
commands also have short forms. Except for the forms of the command names, the commands
are identical.
To perform this procedure, become superuser or assume a role that provides
solaris.cluster.read
and
solaris.cluster.modify
RBAC authorization.
From one node that is connected to the storage array or storage system, determine the paths to
the LUN that you are deleting.

If the LUN that you are removing is not a quorum device, proceed to
Note –
Your storage array or storage system might not support LUNs as quorum devices. To
determine if this restriction applies to your storage array or storage system, see
To determine whether this LUN is a quorum device, use the following command.
#

(A1000 Only)
If the LUN that you are removing is a quorum device, relocate that quorum device to
another suitable storage array.
For procedures about how to add and remove quorum devices, see your Oracle Solaris Cluster
system administration documentation. For a list of Oracle Solaris Cluster documentation, see
