Any way to restart web/management services without restarting the array?

[hux]

I have a Nimble CS700 that's no longer under support. Its web GUI is pretty much non-functional - as in, it will load but trying to do anything after that results in the red pop-up error about web services. At the CLI, most commands result in "Array management service unavailable. Operations may fail."

I deduce from this that certain services that need to be running aren't running. So is there a way to list/start/stop/restart services from the CLI?

From the CLI, do software --precheck

If no errors come back, then do failover
and the controllers will swap Active-Standby state. In the process it should start the GUI on the newly Active controller.

Hi Sheldon,

Thanks for the suggestion. I tried the first command but it failed with the same service error:

Nimble OS $ software --precheck
INFO: Failed to determine if local array is group leader.
ERROR: Update pre-check failed.
ERROR: Array '[my array]' pre-check failed: A service is not running or is not reachable. If the condition persists, contact Nimble Storage Support.

Given that result, I figured I'd better not attempt the failover.

No, we don't offer those commands for normal admin user.

To restart those backend service it requires speical login from support.

Wow! So basically, without maintaining a support contract, if anything goes wrong it's basically a brick?

That's really disappointing. Oh well.

I came across this post becuase I had a similar issue, although I have a support contract. My web GUI was not responding but I could still ping and putty into the array. My agent also said doing a failover will restart web services, but there is a less impactful process to try first. He went in and restarted a process called "jetty" which runs the web GUI. However, that process restarting command is locked behind the nimble support login. The only way to login to that support token is to decrypt the password key, which only support has access to.

 That probably doesn't help you any, unless you can charm your way into support giving you acccess to the support login token.

Best of luck.
