HP StorageWorks Modular Smart Array 20 Msa20 BAREBONES W/trays

Well, for the longest time I have been hpp a vSphere 4. Recently I moved, so I had to move all my servers, storage units, etc… When I got in to the new place, and went to power everything up, I noticed that my first drive had failed upon initializing one of the MSA20 units.

I replaced this drive, let gp rebuild, and thought this would be the end of the issue, but I was incorrect. These people have had HP replace every single item inside of the MSA20 unit except the drives and the issue still occurs.


This made me start thinking. I ran a ADU report and carefully read the entire report. This is very dangerous and you can lose all your data.

This is just me reporting on my experience and usage. In desperation I thought to myself this all happened when a drive failed and I put a new disk in the array. I kept all my vSphere hosts offline, and just turned on the MSA20 units and the SuperMicro server that is attached to them.

I then proceeded to remove a drive, re-insert it, let it rebuild over 3 hours, then when healthy and rebuilt, do it to the next drive. After finally removing and rebuilding each drive in the array, I finally decided to boot up the vSphere servers, and run mda20 backup of my 12 VMs. Not only did everything seem faster, but I completed the backup without any problems.

Rebuilding each drive seemed to fix this. Sometimes the ,sa20 just disappears and in Windows Server Storage Manager I right click and try to reactivate and it does nothing; Continuous rebooting of the MSA box and ho will result in a fix with no rhyme or reason.


I tend to lose everything without rhyme or reason. But like I said a few reboots of everything later and it just comes back with no errors at all. You may use these HTML tags and attributes: Hope this helps someone out there!
