What is the result of typing an entry for the SUBNET variable into the
Serviceguard package configuration script?
Serviceguard package configuration script?
정답: B
Which tool monitors and reports any changes in the cluster?
정답: C
DRAG DROP
Given the following situation, order the steps to create a Serviceguard package that performs disk resource monitoring using EMS. When all paths to the package's shared disk are disabled, a package failover is triggered.
Situation:
- There are two nodes in the cluster.
- The shared volume group is vg01 with the following disks:
/dev/dsk/c0t6d0 with alternate path /dev/dsk/c1t2d0
/dev/dsk/c0t5d0 with alternate path /dev/dsk/c1t1d0
- The vg01 disk device names are identical on both systems.
- vg01 is already cluster-aware.
Assumptions:
- The package is stopped and started at the appropriate times
