Vmware Snapshot + App Consistency

pjagannathan — Thu, 05 Jun 2025 05:53:36 GMT

I have SC 4.0 installed and trying to do a VM snapshot. My goal here is to take a NetApp snapshot of the VM and also ensure application consistency. The application is not in the native plugin list and also not a community plugin.

I decided to use pre/post App quiesce comands which points to a Shell script to quiesce/unquiesce databases.

1. Is this the correct way to go about for databases thats not in the list?

2. I edited the config file and set the param PRE_APP_QUIESCE_CMD01=/usr/local/scAgent4.0.0/sctest.sh

the sctest.sh is a simple test file and has 755 permissions.

ls -l 1>1.out

########## PRE APPLICATION QUIESCE COMMANDS ##########

[192.168.x.x:9090 (4.0.0.1)] Executing Pre application quiesce command [/usr/local/scAgent4.0.0/sctest.sh] on 192.168.x.x

[192.168.x.x:9090 (4.0.0.1)] [agt-00011] Command [/usr/local/scAgent4.0.0/sctest.sh] is not allowed

3. Testing this on 8.2 CDOT lead to timeout errors. Is 8.2 CDOT supported?

Ok, I got past the pre/post script issue. Had to modify the agent.conf file and also move the script to a location outside the SnapCreator install dir.

But I'm still running into issues on CDOT 8.2 though.

Hi -

Just saw this thread. Glad you found the agent.conf setting.

ONTAP 8.2 is not supported with Snap Creator 4.0. It will be supported with Snap Creator 4.1.

That being said, many of us are running Snap Creator 4.0 on ONTAP 8.2 with no problems.

The caveat is that some features added to 8.2 such as SnapVault and CG will not work until Snap Creator 4.1 is released (est January 2014).

Can you post a log so we can get a better feel for where in the process you are hitting errors?

Thanks,

John

Thanks for the response. It pretty much fails right in the beginning of the Job when discovering the ONTAP
