Old iscsi connections
I have a PS6210 group connected to 3 esxi hosts over a private LAN, all set up to use multipath. In EQ group manager, the 2 older hosts show duplicate iscsi connections for each nic (the ones with IPs ending with 21, 28, 29 and 30. The newer host (with the .31 and .32 IPs) doesn't have the duplicate connections.
.
I've scoured my host network configurations to see if I can find a difference, but no luck yet. Any ideas on what I can check?
Hmmmm - just now noticed that VM LUNs with EQ snapshots don't have the duplicates, while LUNs with no snapshots do have them. I'm in the middle of setting up snapshot space for all my VMs, so maybe the duplicates will disappear after the snapshots are created?

Great, thanks. I'm glad you mentioned those. Delayed ack and iscsi login timeout were set correctly on the older servers but not the newest one, and the noop needs to be changed on all, so I'll schedule after I verify any other changes per the best practices doc.

OK. We aren't using VVOLs yet, but I do have chap configured for the group. For data volumes, we are restricting access by IQN of the Windows server that hosts them.

Cool. I had 2 clusters for a while, one of them being a test cluster with older hardware, so the CHAP was really nice for that. Another test cluster is on the list since we refreshed our hardware, but I just have to find the time.
We're running 8.1 now, so I've been loving the folders. On the vm client side, I have resource groups and vm folders, but I tend to use the view with the resource groups more because I'm looking at hosts as much as I'm looking at VMs.
Cheers.
