Reboot an switch:

connect local-mgmt
reboot

Unforantly I deleted all on FI-B / peer farbic and lost the new version. I will apply an update later

Initial Setup done. FI-A/B are "empty"

Server 3, the second big one has a fault RAM dim. Changed 3 - 2 new and orange an old one.

Reset Cisco UCS switches in single mode, we do not need HA on the switch side and don't want to handle a propper switch or os configuration.

Server Overview

[rbo]

The Complete memory subchannel CPU2 N1-3 is not working. I switched the DIMMs between N1-3 and J1-3 and the error stays at N1-3.

Changing the RAM Configuration to 4 DIMMS per CPU to avoid usage of N* slots: Source: Spec Sheet Page 14 found on Cisco UCS B460 M4 Blade Server

I can install RHEL 8.5 on Server 3
