I'm tinkering with a PowerVault 4000 which apparently contains some R620 under the hood.

I've been doing my reading before opening this discussion. I had one successful iDRAC upgrade and the rest have had to be rolled back.

The system started with BIOS 2.4.3 and iDRAC 1.57.57 (and later I noticed on logs that Life Cycle Controller was 1.4.2.12)

I upgraded iDRAC to 1.66.65 with no issues.

I tried to follow suggestions from both Dell Community (and Reddit) to go to 2.10.10 next. The upgrade happened and the iDRAC came back but the server would not turn back on. I rolled back iDRAC to 1.66.65

I upgraded the BIOS 2.4.3 > 2.5.2 > 2.5.4 (eventually)

I attempted to appy iDRAC versions 2.21.21 and 2.30.30 at one point since the Life Cycle Controller was at 2.10.10 (each time LCC upgrades, but iDRAC needs rolled back so the server will power on).

Currently BIOS 2.5.4, iDRAC 1.66.65, and LCC 2.30.30.30

Suggestions?

Thank you!
