If you are managing VSP 5000 series storage systems, note the following.

Notes when performing maintenance work on storage systems

  • If an API request is executed during controller maintenance or when a controller failure has occurred, the API request might fail, and one of the following error messages might be output: KART40047-E, KART30102-E, KART30011-E, KART00007-E or KART20022-E.

    If an error occurs, wait until the maintenance work is complete, and then execute the API request again.

  • If you execute an API request while maintenance work is being performed on the storage system, the API request might fail with the HTTP status code 503 or with the KART40047-E.

    Check with maintenance staff to see whether maintenance work is being performed. If maintenance work is being performed, wait until the maintenance work is complete, and then execute the API request again.

Backing up and restoring storage system settings files

You can also use Hitachi Device Manager - Storage Navigator to back up a REST API database file as the settings file of a VSP 5000 series storage system. You can restore the backed up files by using Storage Navigator.

When the REST API is used to perform the following operations, a good practice is to back up the storage system settings files in order to back up the REST API database.

  • Registering or deleting remote storage system information

For details about backing up storage system settings files, see the System Administrator Guide.

Note:

When you use Storage Navigator to back up or restore the settings files, the REST API services automatically stop. If you attempt to use Storage Navigator to back up or restore the settings files when the REST API services cannot be stopped, the operation will fail. For this reason, do not back up or restore the settings files of a storage system if the REST API is performing an operation or has locked a resource.
