Hi Did someone encountered the issue where all 5 nodes got evicted but no log details as why it happened is recorded? This is 11g R2 5-Node RAC on RHat linux.It happen when SAn Team is working on Storage linked to OCR/Voting Disk. I checked cssd,crsd and CRS/Grid infra Alert log but nothing except the gap of about 25-30 minute in all logs. Please update if I had to look for any other logs on CRS/Grid Infra side. OS logs shows some SCSI errors but SA/SAN team are not ready to take that this is issue on their end and pointing that Oracle has caused all the outage and reboot.
