How to Verify a Nonrolling Upgrade of Sun Cluster 3.1 8/05 Software

Perform this procedure to verify that the cluster is successfully upgraded to Sun Cluster 3.1 8/05 software.

Before You Begin

Ensure that all upgrade procedures are completed for all cluster nodes that you are upgrading.

Steps

1. On each upgraded node, view the installed levels of Sun Cluster software.

   # scinstall -pv

   The first line of output states which version of Sun Cluster software the node is running. This version should match the version that you just upgraded to.

2. From any node, verify that all upgraded cluster nodes are running in cluster mode (Online).

   # scstat -n

   See the scstat(1M) man page for more information about displaying cluster status.

3. If you upgraded from Solaris 8 to Solaris 9 software, verify the consistency of the storage configuration.

   1. On each node, run the following command to verify the consistency of the storage configuration.

      # scdidadm -c

      -c

      Performs a consistency check

      ---

      Caution –

      Do not proceed to Step b until your configuration passes this consistency check. Failure to pass this check might result in errors in device identification and cause data corruption.

      ---

      The following table lists the possible output from the scdidadm -c command and the action you must take, if any.

      Example Message	Action
      device id for 'phys-schost-1:/dev/rdsk/c1t3d0' does not match physical device's id, device may have been replaced	Go to Recovering From Storage Configuration Changes During Upgrade and perform the appropriate repair procedure.
      device id for 'phys-schost-1:/dev/rdsk/c0t0d0' needs to be updated, run scdidadm –R to update	None. You update this device ID in Step b.
      No output message	None.

      See the scdidadm(1M) man page for more information.

   2. On each node, migrate the Sun Cluster storage database to Solaris 9 device IDs.

      # scdidadm -R all

      -R

      Performs repair procedures

      all

      Specifies all devices

   3. On each node, run the following command to verify that storage database migration to Solaris 9 device IDs is successful.

      # scdidadm -c

      • If the scdidadm command displays a message, return to Step a to make further corrections to the storage configuration or the storage database.

      • If the scdidadm command displays no messages, the device-ID migration is successful. When device-ID migration is verified on all cluster nodes, proceed to How to Finish a Nonrolling Upgrade to Sun Cluster 3.1 8/05 Software.

Example 5–1 Verifying a Nonrolling Upgrade From Sun Cluster 3.0 to Sun Cluster 3.1 8/05 Software

The following example shows the commands used to verify a nonrolling upgrade of a two-node cluster from Sun Cluster 3.0 to Sun Cluster 3.1 8/05 software on the Solaris 8 OS. The cluster node names are phys-schost-1 and phys-schost-2.

(Verify that software versions are the same on all nodes)
# scinstall -pv
 
(Verify cluster membership)
# scstat -n
-- Cluster Nodes --
                   Node name      Status
                   ---------      ------
  Cluster node:    phys-schost-1  Online
  Cluster node:    phys-schost-2  Online
