1.) Freeze the service groups for VCS upgrade.
a) Make the cluster configuration read / write.
# haconf -makerw
b) Persistent freeze each and all cluster systems (perform this step for each cluster node).
# hasys -freeze –persistent
c) Save and dump the cluster configuration.
# haconf -dump -makero
 

2.) Upgrade the VCS portion of the product on all systems to 5.1SP1RP2.
a) Stop VCS while leaving the service groups online, running outside VCS.
# hastop -all -force
b) Verify on each node that port h (HAD - high availability daemon) is no longer running.
This is an example of an expected output:
# gabconfig -a
GAB Port Memberships
===============================================================
Port a gen 22590b membership 01
a) Update VCS only on all nodes of the cluster ( the update must be done for all cluster nodes at the same time, or the cluster nodes will not join due to version mismatch errors).
Should run on both nodes:
# cd /cluster_server
#./installer -upgrade_nonkernelpkgs nodeA nodeB
(enter cluster node name when prompted)
b) Update VCS only on all nodes of the cluster to 5.1SP1RP2
( the update must be done for all cluster nodes at the same time, or the cluster nodes will not join due to version mismatch errors).
Should run on both nodes:
# cd /cluster_server
# ./installrp -upgrade_nonkernelpkgs nodeA nodeB
(enter cluster node name when prompted)
Note that the installation script may indicate a reboot upon completion, but no reboot for any of the clustered systems is required at this point in time.

3.) Start VCS on all nodes to verify functionality and switch service groups to one node.
a) Start VCS on each node.
# hastart
b) Verify that the cluster nodes joined successfully by running the command on each node (port a, and h should have a single line in the output).
This is an example of an expected output:
# gabconfig -a     
GAB Port Memberships
===============================================================
Port a gen   22590b membership 01
Port h gen   225916 membership 01
c) Verify the status of the service groups in the cluster.
# hastatus -sum
 

4.) Switch all the service groups to one node (call this nodeA) and persistent freeze the systems.
a) Make the cluster configuration read / write.
# haconf -makerw
b) Persistent unfreeze each and all cluster systems (perform this step for each cluster node).
# hasys -unfreeze –persistent
c) Using the output from step 3c, switch all service groups from nodeB to nodeA.
# hagrp -switch -to
d) Persistent freeze each and all cluster systems (perform this step for each cluster node).
# hasys -freeze -persistent
e) Save and dump the cluster configuration.
# haconf -dump -makero
 

5.) Update VxVM and VxFS on nodeB and reboot.
At this time, VCS is updated on all nodes.
The product installation scripts will only update the lower versions of the installed products.
a) Update VxFS and VxVM on nodeB to 5.1SP1
# ./installer -upgrade_kernelpkgs nodeB
b.) upgrade to RP2:
# cd
# ./installrp -upgrade_kernelpkgs
c) Upon completion of the script, reboot is indicated.
# reboot
NodeB upgrade is now complete.
 

6.) Unfreeze the systems and then switch the service groups from nodeA to nodeB. Then persistent freeze the systems.
a) Make the cluster configuration read / write.
# haconf -makerw
b) Unfreeze the systems.
# hasys -unfreeze -persistent 
c) Switch all groups to nodeB.
# hagrp -switch -to
d) Freeze persistent all nodes.
# hasys -freeze -persistent
e) Save and dump the cluster configuration.
# haconf -dump -makero
 

7.) Update VxVM and VxFS on nodeA and reboot.
At this time, VCS is updated on all nodes.
The product installation scripts will only update the lower versions of the installed products.
a) Update VxFS and VxVM on nodeA to 5.1SP1
# ./installer -upgrade_kernelpkgs nodeA
b.) upgrade to RP2:
# cd
# ./installrp -upgrade_kernelpkgs
c) Upon completion of the script, reboot is indicated.
# reboot
NodeA upgrade is now complete.
 

8) Unfreeze and move groups (if desired) to their original locations.
a) Make the cluster configuration read / write.
# haconf -makerw
b) Unfreeze the systems.
# hasys -unfreeze -persistent
c) Switch any desired groups.
# hagrp -switch -to
d) Save and dump the cluster configuration.
# haconf -dump -makero
e) Verify all service groups are online.
# hastatus -sum
The upgrade is complete.

 

The purpose of this document is to provide an example of the steps required to update a 5.1SP1 on 2-node cluster to 5.1SP1RP2 with minimal downtime. The process given is an example only.
Different configurations / environment may require changes to the steps that are detailed below.
Additionally, this example does not take into account boot disk encapsulation.
During the update process, the Volume Manager and VxFS Filesystem components will remain at a lower level than VCS as the process is completed.
Storage Foundation with Cluster File System (CFS) and / or Oracle RAC require all Veritas product components to be at the same level. Therefore, this process does not apply to CFS or RAC installations.
The process may be modified for use with clusters that have more than 2 nodes.
