HP XP Racks - Manual (Page 295)

Parameters
-k
Specify this parameter to display the Reservation Key. The following
explains the items displayed when the -k parameter is specified:
Reservation Key
An asterisk (*) is displayed at the end of the Reservation Key for a
Reservation Key of another host.
If the Reservation Key is not set, [0x0000000000000000] is displayed.
Regist Key
The registered Keys are displayed.
Key Count
The number of registered Keys is displayed.
-c
Specify this parameter to clear the Reservation Key.
Note
• Do not use the -c parameter during normal operation. Once the
Reservation Key is cleared, the hdisk can be accessed from other
hosts, which may lead to data corruption.
Use the -c parameter only when you need to clear a Reservation
Key that was improperly retained.
• When the hdisk-name parameter is omitted, the Reservation Key
for the hdisks that makes up rootvg will not be cleared. In this
case, the KAPL10670-I message is displayed in the execution
result.
hdisk-name
Specify the hdisk for which you want to display or clear the Reservation
Key. You can specify more than one volume.
If you omit this parameter, the utility assumes all hdisks.
-a
When multiple hdisks are specified, even if an error occurs during
processing, the processing continues for all hdisks.
-h
Displays the format of the dlmpr utility.
Note
[0x????????????????] appears for Reservation Key if the destination
storage system does not support the persistent reservation or if a
hardware error occurs.
Example
To check the Reservation Keys, and then clear the Reservation Keys other
than those for the local host:
