Chapter 28. Managing the system
There are a number of system-related tasks that you can perform on the NAS
Gateway 500. These include:
v Backup and Recovery of the system itself and associated configuration files
v Boot and Shutdown options
v Date and Time settings
v Problem Determination
v System Information
Backup and recovery of the system
This section describes several options available to the NAS administrator or root
user for creating backups using tape and disk devices.
Backup and Recovery using Tivoli Storage Manager (TSM) is described in "Using
Tivoli Storage Manager (TSM)" on page 93. The SMIT path SMIT→Manage
System→Backup and Recovery→Backup and Recovery with Tivoli Storage
Manager (TSM) results in the same menus as SMIT→Managing Applications.
The NAS administrator can backup the NAS system software using the smit
backup command or SMIT→Manage System→Backup and Recovery→Backup
System to Tape / File.
The command listvgbackup displays a list of files in a system backup. This
function is also available using SMIT→Manage System→Backup and
Recovery→List Files in System Backup.
Backup configuration files
After you perform the initial configuration and after making subsequent configuration
changes on the NAS Gateway 500, you might want to perform a backup of the
configuration files where your unique configuration information is stored. This
information is valuable in the event that you need to restore your system.
You can backup these configuration files using the SMIT fastpath smit mknasb.
Restore configuration files
If you need to restore your system or need to restore the set of configuration files
that contain your unique configuration information, you can do so using a backup
that you have previously created.
Attention: Restoring the configuration files overwrites any existing configuration
You can restore configuration files using the SMIT fastpath smit restnasb.
Boot and shutdown
The following sections describe booting and shutdown:

files. You should maintain a backup of your existing configuration files
before you attempt to restore a previous configuration.
