MSA1000 Active/Active 7.00 Controller offline after enable write cache

MSA1000 Active/Active 7.00 Controller offline after enable write cache

If I leave cache set to 100% read 0% write our MSA runs without any noticeable problems for weeks(I only did the upgrade 6 weeks ago). If I change the cache to 90% read/10% write problems start. Within a day there will be a path failover and (so far) the Right controller will "reboot". The only way I have found to restore the controller connection is a disable/remove/re-insert(this may be by design).

Has anyone ever heard of this before? Could it be a cache module problem even though everything seems fine with 100% read cache?

Casey, Can you provide a show tech_support from the MSA cli.

My apologies, I thought I attached this log as a text file to the initial post. This was taken right after re-inserting the controller after an outage.

Hi Branislav, the firmware for the MSA1000 now is the same than for the MSA1500. If you look at the support_show above, it says: Firmware Revision: 7.00b1500
Search in hp.com for downloads for the MSA1500.

Thanks.

I used this firmware, but I was not sure if was the right one.
