Only one path to Equallogic SAN from ESX host

I noticed recently that I noly had one path to my SAN volumes from each of my ESX hosts.
Equallogic is PS4000.
I went through hancocka's guid here for setting up the multiple paths:

I remembered to do the bindings too.
Any idea why I would only have a single path from my host to the SAN?

you've checked the Storage Adaptors, and clicked the LUN, and selected Manage Paths, and only have single path?

Yep-just the one.
I can only see one iscsi connection from my SAN console too.

Did you reboot after the bindings took place? I've had to reboot before it saw the second path.  Also using the same command used to bind please check hte iscsi initiator and verify that it can see both vmk ports bound to the adapter

Hanccokca: There is only traffic on the one bound nic in esxtop
Paulsolov: I used the bind command, and can see both vmks bound to the initiator. No reboot yet, but I can do that after hours one day soon

Please check
 Configuration Tab > Storage Adapters

Choose the Software (or hardware) iSCSI adapter, click properties,
review the settings under static and dynamic discovery.

Is there an IP address listed for each SAN storage processor?

There should be at least two IP addresses in the list, one IP address of each active storage processor.

After adding a new device, you should  Rescan storage devices.


After changing the configuration for an existing iSCSI target, if you are not seeing all the paths, you should place the host in maintenance mode and reboot, in order to force a logout and log-back-in cycle of the iSCSI targets.

Thanks guys. Rescan disks brought up 3 visible paths for each volume.
A restart of the host then gave me the correct number of 2 paths for each
