Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

To reconfigure the LMX module
This section discusses how to reconfigure the LMX module on the node. For the
parameter changes to take effect, you must reconfigure the LMX module.
1
Configure the tunable parameter.
# /usr/sbin/kctune tunable=value
For example:
# /usr/sbin/kctune lmx_minor_max=16384
2
If you use Oracle RAC 10g or Oracle RAC 11g , stop Oracle Clusterware (if
Oracle Clusterware is not under VCS control) and verify that Oracle
Clusterware is stopped. You must also stop applications which are not under
VCS control.
3
Unmount the CFS mounts (if mounts are not under VCS control).
4
Stop VCS by entering the following command:
# /opt/VRTSvcs/bin/hastop -local
5
Check that this node is registered at gab ports a, b, d, and o only.
Ports f, h, u, v, and w should not be seen on this node.
# gabconfig -a
GAB Port Memberships
===============================================================
Port a gen ada401 membership 0123
Port b gen ada40d membership 0123
Port d gen ada409 membership 0123
Port o gen ada406 membership 0123
6
Restart the node by entering the following command:
galaxy> # /usr/sbin/shutdown -r
CFS mounts controlled by VCS are automatically remounted, but you must
manually remount CFS mounts which are not under VCS control.
Applications which are outside of VCS control must be manually restarted.
