I am installing 188.8.131.52 RAC on AIX 7.1 Power series servers. I have two 1gb ports on each server and all these four ports are connected between two switches by cat6 cable.
Installation got completed but when i reboot both server together then only one server comes up with CRS services and other server not able to communicate with CRS.
Case 1: When i put all four cables in switch 1 then both nodes crs is gud.
Case2: when i put 1-1 cable from each server in switch 1 & 2 then it does not.
We tried creating a Vlan2 on both switches and created a trunk too but still not possible.
Please suggest possible remedies.
did you run cluster verification utility for node connectivity?
also check the logs ad $GRID_HOME/log/<hostname>/...
starting with alert.log, then the ones its referencing
