Reboot Single Node
Hi all,
I have a four node p4500G2 cluster in NR5, LeftHand OS12 on each node and esxi 5.5 on the hosts. I discovered one of the nodes has the raid cache incorrectly set and is causing bad io latency.
Same issue as mention here;
My question is can i reboot the single node via the cmc so i can get into the cache settings without affecting the running vm's ?
Thanks

Re: Reboot Single Node
The short answer is, yes. Just right click on the node in CMC and there should be a shutdown/reboot option.
I'd suggest that you change your LUNs from NR5 to NR10 as HP suggests NR5 for archive and read-only data.

Re: Reboot Single Node
Agree with @oikjn about changing to NW10 if you have a "normal" environment. You will see a lot of latency using NW5 for writes. However, if you do change to NR10, your total capacity will drop to 50% where currently it's 75% with a 4 node cluster.
