HP Serviceguard Metrocluster manual Svol

sub-clusters	Sub-clusters are clusterwares that run above the Serviceguard cluster and comprise only the nodes
	in a Metrocluster site. Sub-clusters have access only to the storage arrays within a site.
SVOL	A secondary volume configured in an P9000 and XP series disk array that uses Continuous
	Access. SVOLs are the secondary copies in physical data replication with Continuos Access on
	the P9000 and XP.
synchronous data	Each data replication I/O waits for the preceding I/O to complete before beginning another
replication	replication. Minimizes the chance of inconsistent or corrupt data in the event of a rolling disaster.
T
transparent	A client application that automatically reconnects to a new server without the user taking any
failover	action.
transparent IP	Moving the IP address from one network interface card (NIC), in the same node or another node,
failover	to another NIC that is attached to the same IP subnet so that users or applications might always
	specify the same IP name/address whenever they connect, even after a failure.
U-Z
volume group	In LVM, a set of physical volumes such that logical volumes can be defined within the volume
	group for user access. A volume group can be activated by only one node at a time unless you
	are using Serviceguard OPS Edition. Serviceguard can activate a volume group when it starts a
	package. A given disk can belong to only one volume group. A logical volume can belong to
	only one volume group.
WAN data	Data replication that functions over leased or switched lines. See also Continentalclusters.
