PS6100 health status is critical but there is no error anywhere

Hello,

Our PS6100 had a battery (capacitors board) failure on the first controller, we replaced the board and put the controller back into the NAS. Everything works again, we also forced a switch between first and secondary controller to ensure both works and they do.

However, the NAS is still represented in critical state while I cannot find ANY error in group manager. Is it somehow a leftover from previous status (controlller removed to replace battery) and might vanish later ?

Any idea ?

Best regards, Adam.

It sounds like you've navigated through the challenges of the PS6100 hiccup smoothly by replacing the faulty board and ensuring both controllers are operational. The lingering critical state might be a residue from the prior controller swap, but given your thorough checks and successful controller switch, it's possible it'll resolve itself with time as the system syncs up. Keep an eye on here; glitches sometimes fade away like echoes from previous issues.

Hello Adam, 

 There are a coupe of things it might be, especially if you are using older firmware.   After a CM change there was a timing issue that prevented the error associated with CM removal from being cleared.   So removing it, wait a couple of minutes then reinsert it.    If that doesn't clear it could be the TOD coin cell battery on one or both of the CMs.  I would not expect the error to clear on its own   This CM does not have cache batteries that need charging, 

 Regards, 

Don

Hello,

Controller had been removed for one full day, to be able to replace the capacitor board on my desk so I guess it should have been offline long enough. Coin cell battery could be the issue for sure, but is there any way to check that ? (maybe ssh or telnet, right now all I have is the Java interface). Maybe next time I go there I'll do a preventive replacement of this battery, could you let me know which type it is ? Looks like CR2025 or CR2032...

Regards, Adam.

Here are two pictures of what I'm seeing (see the red cross in first screenshot window title bar)

@acecile​    Hello, 

 Sorry, no I meant you will have to remove it again, or attach a serial cable to it (making sure you are on the passive) and do a restart.  This issue is when you first removed it, it set the HW condition.  When you installed it with the C2F card, that error condition didn't get cleared.  

 Re: Coin cell   I don't know the CR number.    There's no easy way to check it, but that array is older so it's likely due.    

Regards,

Don

Ok, I'll go back to the data center next week and try to take care of this.

I'll let you know if I manage to fix it and will by a bunch of coin cell batteries of different types.

Thanks a lot already for the hint :)

@acecile​   Hello.  Did a little digging, it's a CR2032.

Got a pack of CR2032 and I'll get on site tomorrow. I'll let you know if I manage to fix it this time...

Hello,

I managed to get it green again, thanks to your information. Here is what I did:

1. Replaced cr2032 on the first controller (the one that had capacitors replaced and suspect for the ghost critical error), wait 10/15min before putting back

=> No change

2. Forced reboot to secondary controller

=> No change

3. Replaced CR2032 on second controller, wait 10/15min before putting back

=> No change

4. Full shutdown on Equalogic, wait for both controller to have act led off, pulled both power supply, wait a couple of minuted, plug it back

=> No change

5. At this point it was still running on secondary controller so I decided to pull primary controller again, leave it outside the San for 15 minutes and put it back

=> Critical defect vanished, healthy again

\o/

@acecile​ 

Hello, I am not going to lie that's very strange.  Definitely NOT the issue I thought it was.  

Glad you got it working!   I am glad I could help out.
