The Celerra Management Service is not responding for task Query Data Movers All

Posted by Brajesh Panda on October 6, 2011

Model: VNX 5300

Unisphere: V1.1.0.1.0387

Control Station: Linux release 3.0

Nas Version: 7.0.14-0

Symptom: While browsing File Hardware details like Data Movers, File Network Details etc using Unisphere it didn’t render details & show a warning like “The Celerra Management Service is not responding for task Query Data Movers All

Data Movers looks good from ssh

Ran Health Check & Seems everything is good.

# /nas/bin/nas_checkup

Checked HTTP Daemons in Control Station

Checked NAS Daemons in Control Station

Restarted HTTPD daemon thinking Unisphere might not able to pull in details about data movers

Now Management Service Error gone – New Java webserver error popped up

Again Stopped & Started HTTPD daemon & it comes back to old state

So what is this error? Let’s reboot the control station & see how it is going πŸ˜‰

SSH as Root & reboot

It comes back to good state

However is there a service/daemon which can be recycled to fix this issue without rebooting control station? I will update this thread when I will get to know that πŸ˜‰

Spoke to EMC support, support guy told me – APL daemon was crashing which provides information to unishpere GUI window. Recommended way to restart the control station just to refresh all daemons. Just to note there will be no production downtime due to CS reboot.
