Hello,
I have a pretty basic question that I cannot find an answer for in the knowledge base. Hopefully someone here can help!
First some background: we have a four node AFF8080 cluster. Unfortunately, the pro services company that set us up only configured one spare disk per node. The oldest of the systems has been running for four years and we just had our first failed disk early this morning (which is impressive, but that's another story). When the disk was in pre-fail state and copying to the spare, we got the low spares warning from Unified Manager and I got a call.
I am now waiting for the disk to arrive so I can replace the failed disk. In the meantime I looked around in the knowledge base to be sure I would know what to expect on the off-chance that a second disk failed before I could replace the one that had already failed. (While it seems unlikely, I have seen cases where suddenly multiple disks fail on a system).
I found the KB article shown below for 7-mode systems, but absolutely nothing for cluster mode. I spoke to a NetApp tech who was running the failed disk case but they just pointed me to other 7-mode articles, or a couple of cluster mode articles that didn't fit my scenario. Specifically: when you have 0 spare disks, what happens when a disk fails IN CLUSTER MODE? Can anyone shed light on the answer to this question and preferably point me to a KB article? Thanks so much!
