Explanation: You must first add this disk array host to the NetBackup host configuration before this operation can be performed. To view hosts, see nbemmcmd -listhosts in the NetBackup Commands Guide.
If you try to update an existing host's credentials, this host no longer exists in NetBackup. It must be added again by using the tpconfig or the nbemmcmd command.
The name you entered for the disk array host does not match any of the machine aliases in the NetBackup machine configuration. Use the nbemmcmd command to add the fully qualified array host name (or the name entered) to the machine alias list for your disk array.
