3 node RAC cluster, after power outage, CRS could no longer be started on any of the node. All 3 processes (ocssd.bin, crsd.bin and evmd.bin) are running:

$ ps -ef | grep d.bin
oracrs    6934  6931  0 13:58 ?        00:00:00 /u01/crs//bin/evmd.bin
root      6959 13621  0 13:58 ?        00:00:00 /u01/crs/bin/crsd.bin reboot
oracrs    8206  7078  0 13:58 ?        00:00:01 /u01/crs/bin/ocssd.bin


$ crsctl check crs get:
