Wired Oracle Node reboot mechanism
Node rac1/rac2 in datacenter A
Node rac3 in datacenterB
Both the nodes are in distribution storage:
we just power down all datacenter A:
Node R3 reboot after 21's all disks(including system disks and voting disks and data disks) offline:
Offline time is 2018-11-06 18:28:35---18:28:56 in storage system log
But we found Oracle rac3 has a reboot at 18:29:04,
We found the storage has offline for 21s, Oracle should not reboot,We don't know the reason why it reboot
This is the log:
