We just set up a couple of ESXi 5.0 hosts & have the fibre channel
connections set up to the FC  switches.  EMC has zoned/presented
a LUN to the servers.

It's going to take quite a while before we have access to vCenter
as the network connectivity is pending approval which will take
quite a while.

Q1:
In the meantime, how can we verify the LUN is now visible /
accessible to the ESXi hosts?

Q2:
I've tried out the commands below & then issue UNIX command
"df" or "df -k" but don't see a new partition being mounted.  So
what did I miss? :

To rescan all HBAs:
esxcli storage core adapter rescan --all

To rescan a specific HBA:
esxcli storage core adapter rescan --adapter <vmkernel SCSI adapter name>
(in my hosts, it's vmhba1 & vmhba2 )

Where <vmkernel SCSI adapter name> is the vmhba# to be rescanned. To get a
list of all adapters, run the esxcli storage core adapter list command.


To search for new VMFS datastores, run this command:
vmkfstools -V
