Veritas Storage Foundation 5.1 SP1 for Oracle RAC Release Notes (5900-1513, April 2011)

corresponding CVMVolDg resource is taken offline. Set the value of this attribute
to 1 if you want the agent to deport the disk group when the CVMVolDg resource
is taken offline. The default value is set to 0.
You can set the attribute by running the following command:
# haconf -makerw
# hares -modify cvmvoldg_res CVMDeportOnOffline 1
# haconf -dump -makero
Verify the value of the attribute:
# hares -display cvmvoldg_res | grep CVMDeportOnOffline
Issuing Cluster Volume Manager (CVM) commands from the slave node
In previous releases, Cluster Volume Manager (CVM) required that you issue
configuration commands for shared disk groups from the master node of the
cluster. Configuration commands change the object configuration of a CVM shared
disk group. Examples of configuration changes include creating disk groups,
importing disk groups, deporting disk groups, and creating volumes. In this release,
you can issue commands from any node, even when the command changes the
configuration of the shared disk group. You do not need to know which node is
the master to issue the command. If you issue the command on the slave node,
CVM ships the commands from the slave node to the master node. CVM then
executes the command on the master node.
Note the following limitations for issuing CVM commands from the slave node:
■ The CVM protocol version must be at least 100.
■ CVM does not support executing all commands on the slave node. You must
issue the following commands only on the master node:
■ Commands that specify a controller name. For example:
# vxassist -g shareddg make sharedvol 20M ctlr:fscsi0
■ Commands that specify both a shared disk group and a private disk group.
For example:
# vxdg destroy privatedg shareddg
■ Commands that include the defaults file as an argument. For example:
# vxassist -d defaults_file
