11.6 Verify the New Cluster Member

Finally, let's explore the newly added cluster member and verify that everything is configured and operational.

First, let's take a look at the cluster using the hwmgr(8) command.

 # /sbin/hwmgr -view cluster Member ID        State        Member HostName ---------        -----        ---------------     1            UP           molari.dec.com     2            UP           sheridan.dec.com (localhost)

Now let's see what file systems are mounted. As we can see, the new cluster member's boot_partition is mounted.

 # mount cluster_root#root on / type advfs (rw) root2_domain#root on /cluster/members/member2/boot_partition type advfs (rw) cluster_var#var on /var type advfs (rw) root1_domain#root on /cluster/members/member1/boot_partition type advfs (rw) cluster_usr#usr on /usr type advfs (rw) /proc on /proc type procfs (rw)

Finally, let's check the cluster configuration and see what it looks like. To examine the cluster configuration, we use the clu_check_config(8) command, which checks the majority of the TruCluster Server's individual subsystems. We have trimmed the output to show only member2's information.

As we can see from the clu_check_config output, this cluster looks like it is indeed configured and operational.
