HP Serviceguard Version A.11.19 Release Notes, October 2009

IMPORTANT: As of Serviceguard A.11.19, this capability requires Quorum Server
Version A.04.00. (It is also provided in a patch to Serviceguard A.11.18 with Quorum
Server Version A.03.00, but Quorum Server Version A.03.00 does not support an alternate
subnet with Serviceguard A.11.19.) See “Quorum Server Upgrade Required if You Are
Using an Alternate Address” (page 13).
About LVM 2.0
Logical Volume Manager (LVM) 2.0 volume groups, which remove some of the
limitations imposed by LVM 1.0 volume groups, can be used on systems running
HP-UX 11i v3 0803 Fusion or later with LVM version B.11.31.0809 and Serviceguard
A.11.19. (This support was first introduced in a patch to Serviceguard A.11.18.)
NOTE: You are not required to move to LVM 2.0 volume groups and everything will
work as before if you do nothing.
If you do use LVM 2.0 volume groups, you can still manage them with the same
commands as before, although you may have to make minor changes to any scripts
you use that parse the output of lvdisplay, vgdisplay, pvdisplay or vgscan, as
the output of these commands has changed slightly. In addition, new options are
available for some commands.
For more information, see the white paper LVM 2.0 Volume Groups in HP-UX 11i v3 at
docs.hp.com -> 11i v3 -> LVM Volume Manager. For information about all
other aspects of LVM on HP-UX 11i v3, see the Logical Volume Management volume
(volume 3) of the HP-UX System Administrator’s Guide, at the same address.
About olrad
You must remove a LAN or VLAN interface from the cluster configuration before
removing it from the system. You can do this without bringing down the cluster.
HP-UX 11i v3 provides a new option for the olrad command, olrad -C, to help you
determine whether or not an interface is part of the cluster configuration: run olrad
-C with the affected I/O slot ID as argument.
If the NIC is part of the cluster configuration, you’ll see a warning message telling you
to remove it from the configuration before you proceed. See the olrad(1M) manpage
for more information about olrad.
After removing the NIC from the cluster configuration, you can remove it from an
HP-UX 11i v3 cluster node without shutting down the system by running olrad -d.
See “Removing a LAN or VLAN Interface from a Node” in Chapter 7 of Managing
Serviceguard for more information.
