Oracle RAC 11.2.0.4 node 2 automatic reboot on AIX

edited Oct 1, 2014 5:04AM in Database - RAC/Scalability (MOSC) 4 commentsAnswered

Our RAC environment automatically rebooted one of our nodes, thank goodness it happened while there are no users connected. We assumed it is caused by node evictions, and suspected disk ASM disk unavailability, however we cannot find a concrete cause why this happened. and what can we do to prevent such incidents? Provided logs below for reference.

from alert_node2.log
