Hi,
I have 8 ESX 4.1 (build 348481) blades in a Cisco UCS 5108 chassis. Each blade has 2 x HBAs available. I also have a Fiber channel storage array that is configured to provide 2 1.8 TB LUNs (for now and more in the future).
When I go into vCenter and select any of the ESX servers under "Configuration" -> "Storage Adapters" -> "Rescan All..." each server detects the array (and multiple paths to it) but only shows a single LUN available (LUN 0) when 2 LUNs should actually be available (LUN 0 and LUN 1). See image below.
Now, the thing that is confusing me is that when I get on the ESX server command line via SSH and run "esxcfg-mpath -b" I see a list of all paths including paths to LUN 0 and LUN 1 (see output below). Any ideas on why ESX and vCenter won't allow me to get at LUN 1??
esxcfg-mpath -b :
