I tried to reimage lawrencium today, but no dice.
10:42:56 | lawrencium.eqiad.wmnet | Unable to run wmf-auto-reimage-host: Remote IPMI failed for mgmt 'lawrencium.mgmt.eqiad.wmnet': Command '['ipmitool', '-I', 'lanplus', '-H', 'lawrencium.mgmt.eqiad.wmnet', '-U', 'root', '-E', 'chassis', 'power', 'status']' returned non-zero exit status 1
And
ipmitool -I lanplus -H lawrencium.mgmt.eqiad.wmnet -U root chassis status Password: Error: Unable to establish IPMI v2 / RMCP+ session
I triple checked the pass, it's correct (it works against other hosts anyway)
Next was logging in via the iDRAC. That worked. A racreset did not solve the issue. I checked configuration and unless I am checking something really wrong it looks like iDRAC has IPMI enabled. cfgIpmiLanEnable=1 in the iDRAC's getconfig -g cfgIpmiLan command output.
