Re: EVA 4000 - cache mirroring
There is not much you can do right now except for restarting the controller and opening a call with HP.

Is this a system with older firmware? I see this code mentioned in some notes with improperly handled situations.

Hi Sabastian,
Thank you very much for your kind support, yes, even after restart also OCP is not displaying, find the below Controller backside LED indicators
Port - Controller A - Controller B
Inter Controller - ON - ON
CAB - ON - ON
DP1B - ON - ON
MP1 - OFF - OFF
FP1 - Amber - ON
FP2 - OFF - ON
MP2 - OFF - Amber
DP1A - OFF - ON
UID - OFF - OFF
Please let me know, if you understand anything from this information.
Regards,

Re: EVA 4000 - cache mirroring
The only thing you might try is a standalone bootup of the suspect controller.
1. Remove power from controller
2. Detach all cables including the interlink from the controller
3. Attach power and boot it up / see if anything changes
Doing so could help identify suspect cables. Usually the TEs will report faulty components.

Sebastian

Re: EVA 4000 - cache mirroring
Hi Sebastian,
Thank you very much for your continued support. Yes, we too feel, there may be Controller failure. Currently all our VM's are working in another Controller and I will try your suggestions on Sunday and update you.
But now our backup is running very slow, is this because of Controller failure or low free space in VM server or any other issues you suspect. Plz....
Thanks & Regards,
Kumar

LEDs alone will not help. Remove power from controller and wait about 2min before reattaching. If it does not go trough TEs and does not display anything in the OCP, you should have it replaced.

Re: EVA 4000 - cache mirroring
It's running slow because your one remaining controller now has the handle the load which was split amongst the two controllers. This is also most likely due to the fact that your write caching is now disabled, resulting in write through(writeback) mode, whereby all writes have to go directly to disk, instead of into cache, then into disk.
Open a call with HP immediately, and I would not recommend messing with cabling unless you know exactly what you are doing. One wrong move and you could take out the surviving controller, resulting in a full outage of storage.
Continuing to mess around with the failed controller could cause more problems than you want to even consider. Call the controller dead, and get HP involved.
