4.7.2 Deleting an LU Dynamically
The LU deletion function automatically removes an LU from HDLM management
when all the paths to that particular LU are disconnected.
You can set up the LU deletion function by specifying the
dlnkmgr
command's
set
operation together with the
-rmlu on
parameter. You can also set up this function in
the Options window of the HDLM GUI. For details on the
set
operation, see
3.7.2 Setting Up the HDLM Functions. For details on the Options window, see the
HDLM GUI Help.
(1) Requirements to Delete the LU Dynamically
An LU is deleted when all the paths to that LU are disconnected. This means that an
LU is deleted when HLU is deleted.
When using the
dlnkmgr
command's
set
operation to dynamically delete an LU,
depending on the settings the following differences exist:
When the
-rmlu
on
parameter is specified, the LU is not removed from HDLM
management if the disconnected paths include a path in the
Offline(C)
status.
When the
-rmlu
on
-force
parameter is specified, the LU will be removed from
HDLM management, even if the disconnected paths include a path in the
Offline(C)
status.
(2) Checking that the LU or Path Has Been Dynamically Deleted
This section explains the two operations that can be used to confirm that the LU or path
has been deleted by using the LU deletion function. One operation is performed when
the user intentionally deletes an LU or path, and the other operation is automatically
performed when an LU or path is deleted because all the paths are disconnected.
When the user deletes the LU or path intentionally:
Use the disk administrator, HDLM command, or HDLM GUI to confirm that LU or
path has been deleted.
When an LU or path is automatically deleted due to all the paths being
disconnected:
If an LU is deleted because all the paths are disconencted, HDLM outputs the
KAPL05301-E message to the event log.
