Bug ID

Description

CSCus67247

sNIC is always the first vNIC on each host. If it was not previously there and was added later, it will shift the BDF of all other vNICs, including the iSCSI overlay vNIC.

According to Microsoft, if the BDF location changes then the Windows PNP Manager for iSCSI does not know how to load the driver on the new vNIC, and will not work. The only alternative is to reinstall the OS.

http://support.microsoft.com/en-us/kb/976042/en-us provides more information about this issue.

Known Limitations and Behaviors

There are no known limitations in Release 2.5(1a).
