Nodes may go into an irrecoverable state if shut down and reboot operations are performed using IPMI-based commands
If you use IPMI-based commands such as ipmitool and ipmipower to power off and power on NetBackup Flex Scale cluster nodes, it may cause the nodes to go into an irrecoverable state. (4019742)
This issue occurs because IPMI-based power commands do not perform a graceful shutdown of the operating system before powering off the node. The file systems on the nodes may fail to unmount before the power off, and may fail to mount when the node is powered back on. The file systems eventually appear in a partial or a faulted state. As a result, the NetBackup services containers fail to start and the cluster appears in an inconsistent state.
Workaround:
Do not use IPMI power utility commands to perform shut down and reboot operations on the NetBackup Flex Scale cluster nodes. If you wish to perform maintenance on the nodes, Veritas recommends that you perform a graceful shutdown of the nodes, one node at a time. Use the NetBackup Flex Scale infrastructure management console UI to stop, start, or shutdown the nodes.
For emergency scenarios or in situations where the system is unresponsive and you do not have physical access to the nodes, you can use the SysRq key to force a reboot on the nodes.
Run the following command to reboot the nodes without corrupting the file system:
echo b > /proc/sysrq_trigger
