B200 M4 with VIC 1340 Crashing with any Windows OS

[Samuel Amosah]

Since we started ordering UCS B200 M4 blades with the new 1340 VIC adapter we have noticed that the blades intermittently crash with any Windows server OS (2008 R2 and 2012). The blades display a BSOD stop error as attached. I suspect this is being caused by the new Windows driver for the VIC adapter but because we use iSCSI boot LUNs in our environment no crash logs are generated so I can't be sure. In the Windows event log before the blade crashes there are error messages with the following text: "Storage system does not have a reachable IP address [list of storage controller IP addresses]". We do not have these problems with our M3 blades. Our environment is as follows:

Storage protocol: iSCSI (NetApp)

UCS version: 2.2(3d)

CIMC controller: 2.2(3d)

Adapter firmware: 4.0(1d)

Windows Driver: 2.4.0.15

Any suggestions or help would be much appreciated.

Thanks

Thanks Walter. After installing the VIO drivers and utilities (2.2.3f) and running enictool -i I can confirm the ENIC driver version is 2.4.0.19 and the driver date is 2-3-2015. I've also installed the VIC iSCSI dump tool so i'm hoping that will help me find a solution for this issue.

Any other suggestions or help would be much appreciated.

Thanks
