equallogic

has anyone ever run into a dirty cache issue with a Equallogic SAN. Even after replacement of the controller cards in the Equallogic Storage Array fails offline with a dirty cache.

I have listed steps here on my blog to bring the SAN online again, however this is not the best solution as it continues to fail.

If you have any info on this please share.

Thanks,
