Managing HP Serviceguard for Linux Ninth Edition, April 2009

pr_cleanup lun -v -k <key> [-f <filename_path> | <list of DSFs>]
• lun, if used, specifies that a LUN, rather than a volume group, is to be operated
on.
• -v, if used, specifies verbose output detailing the actions the script performs and
their status.
• -k <key>, if used, specifies the key to be used in the clear operation.
• -f <filename_path>, if used, specifies that the name of the DSFs to be operated
on are listed in the file specified by <filename_path>. Each DSF must be listed
on a separate line.
• <list of DSFs> specifies one or more DSFs on the command line, if -f
<filename_path> is not used.
Examples
The following command will clear all the PR reservations registered with the key abc12
on the set of LUNs listed in the file /tmp/pr_device_list
pr_cleanup -k abc12 lun -f /tmp/pr_device_list
pr_device_list contains entries such as the following:
/dev/sdb1
/dev/sdb2
Alternatively you could enter the device-file names on the command line:
pr_cleanup -k abc12 lun /dev/sdb1 /dev/sdb2
The next command clears all the PR reservations registered with the PR key abcde on
the underlying LUNs of the volume group vg01:
pr_cleanup -k abcde vg01
NOTE: Because the keyword lun is not included, the device is assumed to be a volume
group.
Replacing LAN Cards
If you need to replace a LAN card, use the following steps. It is not necessary to bring
the cluster down to do this.
1. Halt the node using the cmhaltnode command.
2. Shut down the system:
shutdown -h
Then power off the system.
3. Remove the defective LAN card.
4. Install the new LAN card. The new card must be exactly the same card type, and
it must be installed in the same slot as the card you removed.
