MSA1000

MSA1000 fiber attatched to DL380 cluster running RH ES3. querries started running very slow. on shutdown and restart of cluster the array device was not found. it finally found the array after several attemps at restarting both servers and array. no change was made to either the MSA or the DL380s.
How can I prevent this from happeningagain?

Re: MSA1000

This could be any number of things.

Is this connected to a switch that is esclusively used by the DL380 and MSA1000?

Was there anykind of switch zone reconfigurations going on when the slowdown occurred?

Was there a switch failure/failover when this was going on?

I guess you get the idea that you need to look at the supporting infrastructure around how the MSA1000 is connected to the cluster. Look at error logs on the fiber switch(s) and see what you can corolate with the timeframe of the MSA1000 slowdown.

Once it's in production it's all bugs after that.
