Can ESX support multiple ISCSI Targets?

[cod3linux]

We have 3 ISCSI Servers each with their own IP segment. Will\Can ESX support multiple ISCSI Targets? If so how does one go about getting the software initiator to see them. We have 1 ISCSI server attached we would like to attach the other SANS as well.

Do you mean the iscsi are all on different networks? If so, can the ESX server route to all of them?

from what I can remember I thought sofware initiators can only support 1 target, but hardware more. I could be wrong, but here's a good starting point

Yes, ESX can support multiple iSCSI targets. As long as the Service Console(s) and VMkernel interface(s) have direct IP accessibility to each array, you would simply add each array's portal address into the Discovery tab of the iSCSI initiator configuration screen.

If you go for multiple targets in the discovery tab, remember the initiator can only have one CHAP password so all the arrays must share the same security. You also mention the other storage arrays are on separate segments For performance you'd really like to have interfaces on those segments otherwise you'll be routing on your iSCSI traffic which will introduce an additional point of failure.

We got it working in the end it turned out to be user error on my part. While we were rescanning we kept using the scan for new VMFS as opposed to new devices. When we did the latter everything appeared just fine. I want to thank everyone or their input and suggestions.
