Disk drives that contain the Windows operating system and registry are in the integrated file system. You restore these predefined disk drives just as you do user-defined disk drives. To restore disk drives in the integrated file system on i5/OS™, use the Restore (RST) command:
To restore the system (C) drive, use /QFPNWSSTG/nwsdname1. To restore the D drive, use /QFPNWSSTG/nwsdname2.
