AIX – DLPAR connection lost to HMC

Sometime during AIX migration/alt_clone or HMC upgrade, it can happen that RMC ID get lost or duplicated, the the rsct process is unable to re stabilize the connection.

You can reset the key and restart that service as follows:

Reset RMC unique ID:

# /usr/sbin/rsct/install/bin/recfgct
# /usr/sbin/rsct/bin/rmcctrl -z
# /usr/sbin/rsct/bin/rmcctrl -A


Then you can check the rmc status:

# /usr/sbin/rsct/bin/rmcdomainstatus -s ctrmc

The error on planar was located on FAN module, for resolution unplug entire block and single fans, then replug into the planar after cleaning up, then power on your pSeries.
