UCS B200 M5 Boot From SAN-NIC Errors

[JasonGorman1808]

Long story short, we have moved some of our M5 blades from one chassis to another.  2 of the 3 are running fine, but the 3rd is throwing NIC errors shown below:

These blades are boot from SAN so I'm assuming this is a zoning issue. However, I'm not well versed with the 6248UP and zoning, so I'm unsure how to verify this is indeed the issue.

Thank you in a

One thing I'm trying to make sense of is the vnics are showing as not participating for this M5 whereas the other servers vnics are bound to a vpc. How to do I go about associating this M5 blade with a vpc?

UCS vNIC "vif-down" is a common "fault" when the OS driver is not loaded (when the server isn't fully booted or still in BIOS).
("fault" in quotes as this is usually a non-impacting fault. This is not the fault you are looking for </handwave>.)
IMO, "vif-down" fault should have a lower severity or description detailing this fault is expected until the OS is fully loaded.

If you are having boot from SAN issues, focus on the vHBAs.

Thank you Obi Wan. We're getting closer. Seems to be an issue with correct zoning, incorrect LUN ID.

Appreciate your help.
