Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)

SmartTier in a High Availability (HA) environment
The DiskGroup agent brings online, takes offline, and monitors a Veritas Volume
Manager (VxVM) disk group. This agent uses VxVM commands. When the value
of the StartVolumes and StopVolumes attributes are both 1, the DiskGroup agent
onlines and offlines the volumes during the import and deport operations of the
disk group. When using volume sets, set StartVolumes and StopVolumes attributes
of the DiskGroup resource that contains the volume are set to 1. If a file system
is created on the volume set, use a Mount resource to mount the volume set.
The Mount agent brings online, takes offline, and monitors a file system or NFS
client mount point.
If you are using any of the SmartTier for Oracle commands in a high availability
(HA) environment, the time on each system in the cluster must be synchronized.
Otherwise, the scheduled task may not be executed at the expected time after a
service group failover.
