FIRST_CLUSTER_LOCK_PV,
SECOND_CLUSTER_LOCK_PV
The path on this node for the physical volume
within the cluster-lock Volume Group that will
have the cluster lock written on it (see the entry
for FIRST_CLUSTER_LOCK_VG and
SECOND_CLUSTER_LOCK_VG near the
beginning of this list). Used only if a lock disk is
used for tie-breaking services. Use
FIRST_CLUSTER_LOCK_PV for the first physical
lock volume and SECOND_CLUSTER_LOCK_PV
for the second physical lock volume, if any. If
there is a second physical lock volume,
SECOND_CLUSTER_LOCK_PV must be on a
separate line. These parameters are used only
when you employ a lock disk for tie-breaking
services in the cluster.
If you need to change the default entries, make
sure you enter the physical volume name as it
appears on each node in the cluster (the same
physical volume may have a different path name
on each node).
NOTE: If you used the -L lock_vg:lock_pv
option of cmquerycl (1m) to specify the cluster
lock disk, the correct node-specific paths will
already be in the file.
If you are creating two cluster locks, enter the
physical volume names for both locks. The
physical volume group identifier can contain up
to 39 characters (bytes).
For information about changing the configuration
while the cluster is running, see “Updating the
Cluster Lock Disk Configuration Online”
(page 364). See also “What Happens when You
Change the Quorum Configuration Online”
(page 66) for important information.
CAPACITY_NAME,
CAPACITY_VALUE
Node capacity parameters. Use the
CAPACITY_NAME and CAPACITY_VALUE
parameters to define a capacity for this node.
Node capacities correspond to package weights;
node capacity is checked against the
corresponding package weight to determine if
the package can run on that node.
