Today I found out a disk had failed in a production SAN. Oh no!!!

But like previous experiences, this is different. And my support experience is pretty darn good. So I thought lets write this up. Because you always here about the terrible failures and pain in the arse experiences, never the good.

Note:  This post is about the support experience, but it must be noted, there was performance or end user impact during this failure either!

The notifications

So the first notification came in, telling me the disk was unhealthy and that it was being inspected by the array, the main thing is;

• Informed me of the issue
• Informed me of the actions

Second notification, confirmation the RAID was in a degraded state.

Third notification,  confirmation the disk had failed.

The support call

Or rather the lack of support call, I logged onto Nimble Infosight. Continue reading Nimble Storage – The life of a failed disk →
