We recently upgraded UCS Central to 2.0(1h). This was so we would get past a Cisco UCS bug that would delete the VLAN and VLAN Group associations with the port channels in UCS Manager when a lead change was done or if a domain was taken out of Suspend State. Upgrading to UCS Central 2.0(1h) did fixed this issue.
But, now a new issue (bug) has presented itself. Now when a lead change was done or if a domain was taken out of Suspend State, random firmware bundles are getting deleted from the UCS Manager. So far, I have done the lead change or taken out of Suspend state on 5 UCS domains. For two of them, nothing happened. On two others one firmware bundles for the B-Series blades was deleted. Both were different bundles, one 3.2(3d)B and the other 3.2.(3i)B. On the last one, both the B-series blade and the currently running UCS Infrastructure 3.2.(3i)A firmware bundles were deleted.
If a blade, that is on the firmware bundle that was deleted, is rebooted, the server will not boot up correctly.
The Fix:
Re-download the bundles that were deleted to the UCS Manager. You may have to delete any download tasks for the bundles that were already existing.
Once the bundles are download and unpacked, all of the faults will go away and servers can be rebooted again.
