Back up predefined disk drives for integrated Windows servers

When you install an integrated server, i5/OS™ creates the system and installation source (C and D) drives as predefined drives that you need to save. See Predefined disk drives for integrated Windows servers.

1. Treat a Windows network server description, its predefined disk drives, and any user-defined disk drives linked to it as a unit. Save and restore them at the same time. Together they constitute a complete system, and should be treated as such. Otherwise, the integrated server may not be able to reestablish items such as Windows server File System permissions.
2. If the server was created on a pre-V4R5 OS/400® system, see Back up predefined disk drives for integrated Windows servers created on pre-V4R5 OS/400 systems in the V5R3 iSeries™ Information Center.

To save disk drives (network server storage spaces) that are in the system disk pool (ASP) on i5/OS, do this:

1. If you are saving to tape, ensure that you have mounted a tape that is formatted for i5/OS.
2. Shut down the integrated server to prevent users from updating files during the backup. See Start and stop an integrated server.
3. On the i5/OS command line, type SAV and press F4.
4. If you are saving the storage space to tape, specify the name of your tape device (for example, /QSYS.LIB/TAP01.DEVD) in the Device field.

   If you are saving the storage space to a save file instead of to tape, specify the path to the save file as the device. For example, to use a save file named MYSAVF in library WINBACKUP, you would specify '/QSYS.LIB/WINBACKUP.LIB/MYSAVF.FILE' for the device.

5. In the Name field under Objects:, specify '/QFPNWSSTG/stgspc', where stgspc is the name of the network server storage space.
   • For the system (C) drive, use /QFPNWSSTG/nwsdname1.
   • To save the D drive, use /QFPNWSSTG/nwsdname2.
   • For storage spaces created in a user disk pool, use /QFPNWSSTG/stgspc and also dev/QASPnn/stgspc.UDFS, where stgspcis the name of the network server storage space and nnis the number of the user disk pool.
   • For an independent disk pool, use /QFPNWSSTG/stgspc and also dev/independent ASP name/stgspc.UDFS, where independent ASP name is the name of the independent disk pool and stgspc is the name of the network server storage space.
6. Specify values for any other parameters that you want and press Enter to save the storage space.
7. Then, start the integrated server. See Start and stop an integrated server.
