Heads up on Windows 2008 iSCSI Boot Bug

Greetings All,

We've had a few cases coming in regarding this issue so figured we'd post it here for visibility. 

Symptom: 

If the default gateways field is left blank in the iSCSI Boot Parameters, Windows hosts may be unable to find the LUN & Boot properly.  During POST, Cisco VIC option ROM will be able to see the LUN, however during OS boot time, Windows is unable.

Condition:

UCSM 2.0(1) and onward.

Cisco VIC configured for iSCSI boot

Windows Server 2008

iSCSI Initiator & target IP are in same L2 subnet.

Workaround:

Set the Target Array’s IP as the default gateway of the iSCSI Parameters.

Cisco is Tracking this bug under: CSCub65484.  We’re currently working with Microsoft on a fix, no ETA yet but this post will be updated when resolved.

Release notes and Windows Installation Guides are being updated next week.

Regards,

Robert
