Veritas Storage Foundation 5.1 SP1 Cluster File System Release Notes (5900-1509, April 2011)

Note: The CVMVolDg agent takes a volume set offline if the file system metadata
volume in a volume set is discovered to be offline in a monitor cycle. However, if
the CFSMount resource goes offline and the file system on the volume set is
unmounted, the agent retains the online state of the volume set even if the
metadata volume in the volume set is offline. This is because the CVMVolDg agent
is unable to determine whether or not the volumes that are offline are metadata
volumes.
New attribute CVMDeportOnOffline
The CVMDeportOnOffline attribute setting enables the CVMVolDg agent to
determine whether or not a shared disk group must be deported when the
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
Changes related to Veritas Volume Manager
Veritas Volume Manager (VxVM) includes the following changes in 5.1 SP1:
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:
