Remove Logical Drive LUN Mapping
This command removes the logical unit number (LUN) mapping.
Syntax
remove (allLogicalDrives | logicalDrive [logicalDriveName]|
logicalDrives [logicalDriveName1 ... logicalDriveNameN] | accesslogicalDrive)
lunMapping (host=”hostName”|
hostGroup=(“hostGroupName” | defaultGroup))
Parameters
Parameter Description
allLogicalDrives This parameter removes the LUN mapping from all of the
logical drives.
logicalDrive or
logicalDrives
The name of the specific logical drive that you want to
remove from the LUN mapping. You can enter more than
one logical drive name. Enclose the logical drive name in
double quotation marks (“ ”) inside of square brackets
([ ]).
accessLogicalDrive This parameter removes the access logical drive.
host The name of the host to which the logical drive is mapped.
Enclose the host name in double quotation marks (“ ”).
hostGroup The name of the host group that contains the host to which
the logical drive is mapped. Enclose the host group name
in double quotation marks (“ ”). The defaultGroup value is
the host group that contains the host to which the logical
drive is mapped. The HostGroup and Host parameters can
not be specifed together. You can specify either parameter
but not both at the same time.
Notes
The access logical drive is the logicalDrive in a SAN environment that is used for communication
between the storage management software and the storage subsystem controller. The access logical drive
uses a LUN address and consumes 20 MB of storage space that is not available for application data
storage. An access logical drive is required only for in-band managed storage subsystems.
Attention: Removing an access logical drive can damage your configuration – The agent uses the
access logical drives to communicate with a storage subsystem. If you remove an access logical drive
mapping for a storage subsystem from a host that has an agent running on it, the storage management
software is no longer able to manage the storage subsystem through the agent.
You must use the host parameter and the hostGroup parameter when you specify a non-access logical
drive or an access logical drive. The script engine ignores the host parameter or the hostGroup parameter
when you use the allLogicalDrives parameter or the logicalDrives parameter.
Remove Member Logical Drive from Consistency Group
This command removes a member logical drive from a an existing Enhanced FlashCopy consistency
group. Optionally, you can delete the repository logical drive members from the consistency group.
