Migrated off of a pair of mirrored EVA8000(P6000)'s to a snap-mirrored set of V3240s. (one with 600GB SAS, the other 2TB SATA) (NetApp Release 8.2.3P4 7-Mode) running over FC with Emulex LPe12000 HBA's.
VM Server access is really slow now, along with User data access.
VMWare ESXi Host (5.1U3) is showing a lot of latency errors like below.
Device naa.60a980004431396a375d444859356e31 performance has deteriorated. I/O latency increased from average value of 4329 microseconds to 87418 microseconds. warning 1/31/2017 1:04:55 AM 10.80.1.237
Anyone have any ideas what might be going on, and what to look for to fix it?
