If you can configure SNMP traps to notify when the CAVA service stopped, you can issue a command to restart it.  Unisphere CLI provides this functionality:

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /net/nas/cava show

-- shows the state of the CAVA service on the VNXe

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! net/nas/cava -enabled yes

-- starts the CAVA service on the VNXe

If SNMP isn't option, you'll need to find another way to receive the notifications and act accordingly.

Let us know if that helps!

Hello Karl,

Thank your for your answer and your help (I ) .

The principal issue is that the VNXe doesn't generate alert when the Cava Service is stopped.

> When the "Shutdown" CAVA parameter is set to "viruschecking", the CAVA service is stopped and any event is sent.

Users can access to files but the CAVA service is not restarted automatically (never if you don't check the status yourself).

> When the "Shutdown" CAVA parameter is set to "no",  a log event is sent to the VNXe Shared Folder Server. But I don't know if this parameter stop the file access to users (impact on the production).

Is it possible to do a script that check the Cava service status and start it of Cava Status is "no" ?

Hello Brett@s,

Thanks for your answer. It is very helpfull. I will show that to my colleague to try to test it.

If you can use powershell this should work;

$cavacheck = (uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /net/nas/cava show)

if ($cavacheck -like "*Enabled = no*") {uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /net/nas/cava -enabled yes}

Schedule to run via Windows Task Scheduler as often as required.

It's a bit crude and basic, and you could add more functionality like email report if it wasn't started or if there's an error.

This is checking for the "Enabled = no" line in the /net/nas/cava show output. You could also check for the "State" information if that's more relevant.

If you want more detail let me know and I'll make something nicer
