Question Yes the SBI-4129P-T3N BIOS 3.1 or 3.1a (we tried both) Current IPMI firmware 3.60 CMM versionb 3.42   Going into the web management of the IPMI for each blade, then to the "firmware update" to downgrade to 3.27 IPMI firmware. It completes, the system reboots, then the system is completely unresponsive and the CMM node management says "Initializing" on each of the downgraded motherboards. They cannot be powered on or accessed in any way. Seems to "brick" the node if you downgrade the IPMI firmware. We have 3 nodes now that are this way. We need a solution. Answer Current downgrade process >> will crash BMC Downgrade : should from 3.60 >> 3.51 >> 3.27 Down grade process including BIOS >> Checked by Lab and worked. 1. BIOS 3.1a to 3.0a 2. System boot up 3. IPMI 3.60 to 3.27 Was this FAQ helpful?
