Catalog replication may fail to resume automatically after recovering from node fault that exceeds fault tolerance limit
Catalog replication stops when a fault exceeds fault tolerance limit and is resumed automatically after the faults are restored. But in some cases, the NetBackup Flex Scale cluster may fail to resume the catalog replication.
The following disaster-recovery status API can be used to get the status of catalog replication and the replication status shows that it is paused due to network disconnection.
API:
GET /api/appliance/v1.0/disaster-recovery
Response:
replicationStatus: paused due to network disconnection
(IA-32203)
Workaround:
Reboot all nodes of the NetBackup Flex Scale cluster on the site where the node fault tolerance exceeded the tolerance limit.
Run the following command to restart the cluster nodes.
# echo b > /proc/sysrq-trigger
