I'm using Adaptec's iSCSI hardware initiator. The driver is the latest
version I downloaded from their website. A NetApp filer is the device
exporting LUNs over iSCSI.

I can provide a user-mode version if a working Linux one isn't found.
The UNH code is not the cleanest. The few people I know who've tried it
have had problems.

The HW initiator can supposedly boot off of LUNs now. Britt Bolen -
mentioned in another e-mail figuring out the contortions required to get
iSCSI root with the Cisco initiator.
