You may have to remove attributes from your storage server. Usually, you remove attributes to change or remove functionality.
If you remove attributes on the storage server, you also must remove the same attributes on the existing disk pools. Any disk pools that you create after you update the storage server inherit the storage server functionality.
To remove an OpenStorage storage server attribute
Run the following command on the NetBackup master server or on a storage server:
install_path\NetBackup\bin\admincmd\nbdevconfig -changests -storage_server hostname -stype server_type -clearattribute attribute
For hostname, use the name of the disk appliance host. For server_type, the OpenStorage vendor provides the string that identifies their storage type. For attribute, use the name of the attribute you want to clear.
