iSCSI HBA - boot from SAN

Hi fellow experts!

After a bit of confirmation on something from anyone who has tried it:

Using a iSCSI HBA with INT 13 (Boot from SAN) such as [10Gb 534FLR-SFP+] I know the OS be booted from this HBA, but can another iSCSI target be mounted too (data drives) using the same HBA that was booted from?

Probably using HP hardware in this case, but should be vendor agnostic in theory.

iSCSI steps
1.      Boot Server
2.      iSCSI HBA mounts the OS as C: from SAN (1st target in bios)
3.      OS Boots
4.      Windows iSCSI initiator uses the same HBA to mount D: from SAN

The initiator IP will remain the same.

I am hoping this will be just another session on the HBA, but want to confirm if the HBA will be reusable/sharable after initial ‘bios’ initiation.

Anyone tried this and can confirm it does/doesn't work?

I last setup boot to iSCSI SAN about 8 years ago, but there was no issue using built in software iSCSI initiator, and you should be able to do full hardware offload to the HBA.

Of course, with virtualization boot to SAN is a really niche case. I suppose you can boot the hypervisor from SAN...

Thanks for the reply. Glad someone's out there :-)

Did you mount multiple drives/LUNs on the same HBA that you booted from?
Well, sort of, as I was using the software initiator inside the OS, but I don't see any reason why the hardware HBA wouldn't work as expected.

Yea, that's what I thought. Just wanted confirmation from someone who had actually done it.
