Hello Erez-

The HeaderDigest setting here indicates a list of options [None, 
CRC32C].  If running on iSER, we'll negotiate to "None", and all will be 
well.

I would like to take your advice, but the distribution that I am using 
does not have the iscsi_discovery with the "-t" option, so I just used 
static.  It could be that what I'm running just won't work (we have 
discussed offline a known-to-work configuration, I will try that).  As 
an aside, I think it's kinda nutty that there's a chance that the RHEL 
5.2 config doesn't work... since, eh, well it's ship

There may be something else in the config, though.  I'm just trying to 
figure out what this is:

# iscsiadm -m node -T 
iqn.1986-03.com.sun:02:aff22998-3466-4bf4-ee3c-958fd4b5d346 -p 
10.8.0.6:3260 -l
Login session [iface: default, target: 
iqn.1986-03.com.sun:02:aff22998-3466-4bf4-ee3c-958fd4b5d346, portal: 
10.8.0.6,3260]
iscsiadm: initiator reported error (14 - iSCSI driver does not support 
requested capability.)
iscsiadm: Could not execute operation on all records. Err 107.
#


I have yet to find it in the code (but I do have my day job).  If I 
don't hear anything, I'll just roll back to RHEL 5.2.

Best
Jesse
