Platform: Linux

Automatically execute your customized script before or after upgrade

An interface is provided to automatically perform customized script before or after the upgrade. Put your executable script in the specified folder for the auto-execution.

If you want the script to be run before the upgrade

Create a folder /var/tmp/prestop on the master node.
Copy the script into the folder.

If the script exits with error (exit code of the script executing is not zero), you are prompted to confirm whether to continue the upgrade:

CPI WARNING V-9-0-0 Prestop script /var/tmp/prestop/test.sh failed \
to be executed on test_02, the return code is 2.
Do you want to continue? [y,n,q]

If you want the script to be run after the upgrade

Create a folder /var/tmp/poststart on the master node.
Copy the script into the folder.
If the script exits with error (exit code of the script executing is not zero), you can see a warning message similar to the following:
```
CPI WARNING V-9-0-0 Poststart script /var/tmp/poststart/test.sh \
failed to be executed on test_02, the return code is 2.
```

The script would be automatically copied to other nodes and executed on each node.

Note that there should be only one executable script in the /var/tmp/prestop or /var/tmp/poststart folder, otherwise the upgrade fails with the following error messages:

CPI ERROR V-9-0-0 Don't know how to execute prestop or poststart \
script, please check the scripts.
Only 1 script is supported and it should be executable.

Note:

Make sure there is no node rebooting operations in the customized script, because Veritas Access doesn't support node rebooting during upgrade.
