I am confused now after going through the support document from tech-support. I know I can reopen the closed case but I want to discuss here before that..
Following is procedure suggested to me by support,
** 1. “Node A”.
Download patches.
** 2. “Node B”
Failover all services to “Node B”.
Make sure all service groups are frozen and non-critical.
# hastop –all -force
# hasys -freeze <SystemName>
** 3. ”Node A”
VCS should already be down on "A"
Copy /etc/llttab /etc/llthosts /etc/gabtab files to .SAV files and make a backup.
Unencaplulate root drives. ( You may be able to skip this step )
Load patches and reboot.
# hastatus sum
** 4. “Node B”
# hastatus sum
Unfreeze services on "B"
# hasys -unfreeze <SystemName>
** 5. “Node B”
Failover the services one at a time (review dependencies) to “Node A”
Verify all services are down on “Node B” and running on “Node A”
Make sure all service groups are frozen and non-critical.
# hastop –all -force
# hasys -freeze <SystemName>
** 6. ”Node B”
Repeat the upgrade process on “Node B”.
Unencaplulate root drives. ( You may be able to skip this step )
Load patches and reboot.
Reboot
# hastatus -sum
I am confused now, what I want to do is keep application(bb) running on nodeB-so that client side does not have problems and at that time patch Node1. I do not want the services go down for client. I think in step #2 if I freeze NodeB all service groups will be offline and then applications will go offline and clients can not access bb service group which is running blackboard.
1.Can someone modify the above to what I need to do to patch the nodes while appplications keep running on one node atleast.
2.Do I need to give commands below also which tech support has not given ...
hagrp -switch bb -to bbserver2 or bbserver1
3. what would be <system name> for step # 2, #4, #5
this is VCS summary at my end,
hastatus -sum
-- SYSTEM STATE
-- System State Frozen
A bbserver1 RUNNING 0
A bbserver2 RUNNING 0
-- GROUP STATE
-- Group System Probed AutoDisabled State
B ClusterService bbserver1 Y N OFFLINE
B ClusterService bbserver2 Y N ONLINE
B bb bbserver1 Y N OFFLINE
B bb bbserver2 Y N ONLINE
Also after patching node1 or nodeA I want to transfer all application service(bb) and cluster service to node A and try running it there. if users are satisfied then I want to patch nodeB or node2.
if you need more information I can give..
but please send me step by step way for patching..
