Hello,
can anyone describe the procedure for direct attached fibrechannel?
Right now we have a 2240-2 HA (running ONTAP 8.1.3SP2) with FC modules installed:
NetApp Ctrl 1: FC Adapters
1a connected to ESX#1 Port 1
1b connected to ESX#2 Port 1
NetApp Ctrl 2: FC Adapters
1a connected to ESX#1 Port 2
1b connected to ESX#2 Port 2
Now we created igroups on each controller
Ctrl1 and Ctrl2: each igroup consists of WWPNs:
ESX#1 Port 1, ESX#1 Port 2
ESX#2 Port 1, ESX#2 Port 2
(so each igroup consists of 4 WWPNs).
Ctrl1: Igroup 1 consists of 4 WWPNs with LUN 0 and 1
Ctrl2: Igroup 2 consists of 4 WWPNs with LUN 2 and 3
(I had to change LUN ID manually, otherwise System Manager complained about "Partner has LUN mapped already")
In VMWare we installed the VSC 4.2 and executed the optimized adapter settings.
When I look into the paths I see each ESX Hosts has two paths to every LUN, one marked with active (I/O) and one marked only "active", so everything seems to be ok.
Question is, is multi-path setup right? Failover test was successful, but I wonder if I have to do any other settings, like multi-path type selection (round robin, etc)
Do I have to take any other settings in ONTAP?
