Re: EVA 4000 - cache mirroring
Hi Thomas,
Thank you very much for your help. This hardware is not under AMC and HP is not ready to take this call. We asked to take this call per call basis but HP is demanding for AMC and they quoted very high price.
Can we enable write-through from write-back option? please help me....
Regards,
Kumar

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.

Hi Sebastian,
Thanks for your support. Sure as VM's are running in another controller and meantime we will try to get the replacement controller and replace it.

Kumar
