[linux-iscsi-users] hooking up to Promise VTrak M300i with CHAP

[Eric S. <Eric@Clickability.com>]

So, I got everything working without authentication just fine.  The
problems came when I tried to get CHAP working ...

=20

I have a testinitiator user set as a "Peer" (target authenticates
initiator) and a testtarget user set as "Local" (initiator authenticates
target).  In my iscsi.conf file I have the following set:

=20

OutgoingUsername=3Dtestinitiator

OutgoingPassword=3Dpasswordpassword

IncomingUsername=3Dtesttarget

IncomingPassword=3Dpasswordpassword

=20

When I try to connect I get the following in the /var/log/messages
(edited for brevity):

=20

Connected to Discovery Address 192.168.3.244

Login failed to authenticate with target

Discovery login to 192.168.3.244 rejected: initiator error (02/01),
non-retryable, giving up

=20

Now I've got this to work with the Microsoft iSCSI initiator with
bidirectional authentication, so I know it's theoretically set up
properly on the M300i.  Anyone have some pointers on CHAP in general, or
specifically with the Vtrak device?

TIA
