Cache Plugin install

TIMOTHY_P_LANE — Thu, 05 Jun 2025 05:45:41 GMT

I am trying to get the SC server to recognize the CACHE plugin I have installed on an AIX server.

The SC Agent has the CACHE.pm file in the /usr/local/scAgent4.0p1/plugins/CACHE/ directory on the AIX box.

I restarted the SC Server and SC Agent. When I run discover I get the message:

Action started!

2 ########## Agent validation ##########

3 Agent validation completed successfuly for agent 10.255.4.80:9090

4 ########## Plugin validation ##########

5 Plugin validation file for plugin CACHE not found, skipping validation

6 Application auto discovery is not enabled skipping .

7 Validate volume is not enabled skipping validate volume task.

8 ########## Snap Creator Framework 4.0p1 finished successfully ##########

9 INFO: Snap Creator Framework finished successfully (Action: discover)

I saw a similar discussion thread but it didn't provide a solution.

Hello Tim,

With the CACHE plugin, I see only quiesce and un-quiesce operations implemented.

Could you please try quiesce and un-quiesce operation (basically backup) and report the debug logs here?

Thanks,
Siva Ramanathan

Hello Siva,

When I run the quiesce action I get the following output.

From the logs it looks like the quescing action is successful.

Please perform an unquiesce action as well, as you can't leave the backup in quiesce mode for long time.

From the Snap Creator GUI, you call only the "backup" operation.

It takes care of the quiesce->snapshot->unquiesce action.
