up a cluster configuration. In this case, this utility clears the Reservation Key
to cancel the persistent reservation.
Format
/usr/DynamicLinkManager/bin/dlmpr {{-k | -c} [hdisk-name] [hdisk-
name] ... [-a] | -h}
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.
If you set the reservation policy to PR_shared, the reservation for
all nodes that use the corresponding hdisk is cleared, so hosts that
did not share the reservation can now access the hdisk. This might
lead to data corruption. To clear only the reservation from an
execution node, use dlmrmprshkey Utility for Clearing HDLM
Persistent Reservation (Shared-Host Methodology) on page 7-31 .
If you set the reservation policy to PR_exclusive, data might
become corrupted because another host can now access the
specified hdisk.
• 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.
