If VCS upgrade fails on one or more nodes, HAD fails to start and cluster becomes unusable
This issue may happen in cases where you are upgrading a multi-node VCS cluster. If the upgrade succeeds on at least one node but fails on one or more nodes in the cluster, the VCSHigh Availability Engine (HAD) may fail to start on the nodes on which the upgrade has failed.
The VCS installer does not let you remove VCS from those nodes with an error that those nodes are part of a cluster. The VCS Cluster Configuration Wizard (VCW) does not let you remove those nodes from the cluster with an error that the nodes have a different version of VCS installed.
As a result, you cannot perform any operations on the cluster. (1251272)
Workaround: To get the cluster running, you must manually remove the nodes on which VCS upgrade failed, from the cluster. Then, use the cleanup scripts to remove VCS from the nodes on which the upgrade failed, reinstall VCS, and add the nodes to the cluster.
Perform the following steps to remove the nodes on which the VCS upgrade failed, from the cluster:
To workaround this issue
- Stop HAD and LLT on all the cluster nodes.
Type the following on the command prompt:
net stop had
net stop llt
- On a node on which VCS was upgraded successfully, open the file
llthosts.txt
and delete the entries of all the cluster nodes on which the upgrade failed.For example, consider a cluster with three nodes, N1, N2, and N3.
The
llthosts.txt
file contains the following entries:# This is program generated file, please do not edit. 0 N1 1 N2 2 N3
If the upgrade failed on N3, delete the last entry from the file.
So the modified
llthosts.txt
file should look like this:# This is program generated file, please do not edit. 0 N1 1 N2
The
llthosts.txt
file is typically located at C:\Program Files\VERITAS\comms\llt.Here C:\ is the drive on which VCS is installed.
- On the node on which you performed step 2, open the
gabtab.txt
file and modify the entry to reflect the exact number of nodes in the cluster.The
gabtab.txt
file contains the following entry:#This is program generated file, please do not edit. gabconfig -c -n <number of nodes in the cluster>
The <number of nodes in the cluster> should be the number of nodes on which VCS was upgraded successfully.
Considering the example in step 2 earlier, the
gabtab.txt
file contains the following entry:#This is program generated file, please do not edit. gabconfig -c -n 3
As the upgrade failed on one out of the total three nodes in the cluster, the entry should look like this:
#This is program generated file, please do not edit. gabconfig -c -n 2
The
gabtab.txt
file is typically located at C:\Program Files\VERITAS\comms\gab.Here C:\ is the drive on which VCS is installed.
- From the Windows Services snap-in, change the startup type of the Veritas High Availability Engine (HAD) service to Manual.
- Repeat step 2, step 3, and step 4 on all the nodes on which VCS was upgraded successfully.
- On one of the nodes on which VCS was upgraded successfully, open the VCS configuration file main.cf in a text editor and remove the entries of all the cluster nodes on which the VCS upgrade failed.
The
main.cf
file is located at %VCS_Home%\conf\config.The variable %VCS_HOME% is the default installation directory for VCS, typically C:\Program Files\VERITAS\Cluster Server.
- Start HAD on the node on which you modified the VCS configuration file in step 6 earlier.
Type the following on the command prompt:
net start had
You can remove VCS from the affected nodes using the cleanup scripts that are provided with the software. These scripts are .bat files located in the \Tools\vpi directory on the software DVD. Refer to the readme.txt
file located in the directory for details on how to use the cleanup scripts. After removing VCS, install VCS using the product installer and then add the nodes to the cluster.
