Ocfs2, server reboot?

Question

Red Hat Enterprise Linux

Hello.
There are:
2 nodes on which oracle linux is installed. an external raid array is connected to each node via iscsi. the array is formatted in ocfs2.
Situation:
a controller failure occurred on an external raid array, as a result of which both nodes went into reboot. As I understand it, ocfs2 is to blame.
Want:
How can I prevent servers from rebooting when an external raid controller freezes? There was a similar reboot when networkers reconfigured the network between nodes and an external raid.
