Cisco UCS firmware update bug

Just received an email from a peer in the industry (Gabrie van Zanten) which identifies an issue when upgrading UCS firmware.  I thought I would share as many companies I know run Cisco UCS.

The Issue

When upgrading the UCS firmware of your environment, some B200M4 blades may reboot spontaneously.

Cisco Bug: CSCut61527 – B200M4 could reboot on shallow_chkpt when BMC returns invalid FRU data. This is the Cisco article.

Affected firmware: 2.2(3) and 2.2(3a)A according to the KB. My upgrade was from 2.2(3c) to 2.2(3f).

Resolution

According to the KB this issue should be resolved in 2.2(3g)A.
