Adding an excluded disk to the cluster
A disk is excluded from a cluster if there are frequent transient errors for the disk. A disk gets excluded if the time difference between the last failure and the current failure is less than six hours and this happens at least five times or more. For a disk that is excluded, the disk status is shown as excluded on the page of the NetBackup Flex Scale UI.
Note:
NetBackup Flex Scale automatically detects and sets the disk status to excluded if there are frequent disk errors. You do not have the option to set the disk status to excluded.
You can perform the following operations for an excluded disk:
Include the excluded disk: You can include the same disk that is set as excluded. If multiple disks are excluded, include the disks one by one.
Replace the excluded disk: To replace an excluded disk, first physically remove the old disk and insert a new one. Perform a replace disk operation on the new disk.
To include an excluded disk:
- Use any one of the following options to log on using the user account that you created when you configured the cluster:
Use a user account with both Appliance administrator and NetBackup Administrator role, or a user account with only an Appliance administrator role to log on to the NetBackup Flex Scale web UI
