Recently I posted a question on HP Proliant DL180 G6 - Smart Array P410, bay 11 error which the answers helped me to dig through. And today that I just noticed under my vSphere log which gives a continuous I/O latency error as seen below;
As per my previous question, I'm not sure whether this happens due to one drive has been corrupted or missing according to the array controller. Our server is on a RAID 6 and I'm waiting until I get the NAS set-up, so that I can back up all the VM(s), then replace the effected disk.
What I also would like to know is that, to re-initialize a disk on RAID 6, do I have to remove it & re-add when the server is on or to do it once shut downed?? I'm sorry, I'm quiet unsure I don't have much more experience on RAID to be honest.
Any help will be highly appreciated.
