Replacing a disk
If a disk of a node is in a faulted state, replace the disk to maintain the resiliency of the cluster. A cluster with up to five nodes can tolerate a loss of one node and a disk. A cluster with six or more nodes provides resiliency of two nodes, or two SSDs, or four HDDs. The NetBackup jobs continue to run as long as the fault tolerance is not exceeded. If the failures exceed the fault tolerance, the cluster runs in a degraded state where NetBackup and MSDP services might not be running on all the nodes.
Alerts are generated for faulty disks. See Viewing information about alerts.. If Call Home is configured for your setup, diagnostic information is sent to the AutoSupport server.
Before you begin the disk replacement operation, complete the following tasks:
Remove the faulty disk from the node and replace the faulty disk with a replacement disk.
Note:
On HPE ProLiant Server setup, you must power off the node before physically replacing the faulty NVMe SSD disk .
Ensure that replacement disk is the correct size and is formatted.
To replace a disk:
- Use any one of the following options to log in using the user account that you created when you configured the cluster:
Using an user account with an Appliance Administrator and NetBackup Administrator role, log in to the NetBackup web interface
https://ManagementServerIPorFQDN
where ManagementServerIPorFQDN is the public IP address that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration, and then in the left pane click Appliance management.Using an user account with an Appliance Administrator role, log in to the NetBackup Flex Scale web interface
https://ManagementServerIPorFQDN:14161
where ManagementServerIPorFQDN is the public IP address that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration.
- In the left navigation pane, click Monitor, click Infrastructure, and then click Disks.
The disks of all the nodes are displayed. In the Status column, the failed disks are marked as faulted.
- Click the faulty disk that you want to replace, and then click Replace disk.
The replacement disk is detected and added to the node.
