Backup Blues AS/400 integrated NT4 serv

By Loketar ·
We are using an AS/400 system with an integrated NT4 server. The two systems share the same disk array via a dual channel controller. Backups are extremely fast on the AS/400, however we are forced to use a second workstation to backup the NT4 storage area because we are unable to get it to access the directly connected AS/400 tape drive. I have been told that Integrated NT backup is available via a AS/400 device but I have had no luck in getting it to work. The problem is that the integrated nt server will not recognize the tape drive as a device attached to system. Does anyone have any similar experience that could shed some l light on this little frustration. Thanks in advance for your help.

More to follow due to Techrepublics buffer size.
The OS/400-Windows NT integration that IBM introduced with V4R2 allows an IPCS-hosted Windows NT Server computer to access both the AS/400’s tape backup device and CD-ROM. Although it’s aminor irritation, sharing these resources is a dedicated process requiring explicit user switching. That is, before using the AS/400 tape backup or CD-ROM with Windows NT Server, you must first toggle either device as being “owned” by Windows NT Server. Until toggled back, the Windows NT-owned device isn’t available to the AS/400.
Because the AS/400 sees each virtual disk drive (drives C to U on Windows NT Server) that is allocated to Windows NT Server as a single OS/400 object, each of these OS/400 objects can be backed up in its entirety from the AS/400. You can’t do by-file or by-folder Windows NT Server backup from the AS/400 side. And consequently, you can’t do a by-file or by-folder restore from backupsperformed on the AS/

When you toggle the tape drive for Windows NT Server use, you can perform by-file or by-folder Windows NT Server backup from Windows NT itself, using Windows NT Server-hosted backup utilities (just like you would on a external server).
Backing up the Windows NT Server from the AS/400 side has a few advantages. By tweaking an AS/400 nightly backup script, you can back up one or more Windows NT Server drives at the same time you’re backing up your AS/400 data. This assumes, of course, that there is room on the tape for the Windows NT drives you’re backing up. Another advant

This assumes, of course, that there is room on the tape for the Windows NT drives you’re backing up. Another advantage of backing up the Windows NT Server from the AS/400 side is that it provides a good way to replicate a Windows NT Server environment quickly. For example, a Windows NT Server in Miami can be saved with this method and easily restored on another IPCS card in Detroit. Indeed, this is possible with external Intel servers, but variations in firmware, BIOS and hardware drivers on external Intel servers make it much less likely to be successful. Windows NT Server backup, initiated from the AS/400, provides perhaps the best argument for hosting Windows NT Server on the IPCS card for an existing AS/400 shop.

We are in a similar boat to you & using separate backups for NT vs. AS/400.

I agree with Tyson Mathews that an object needs to belong to OS/400 or to some other operating system. We have communications lines that belong to only one protocol at atime, so we have a menu to rapidly switch between which is the owner.

It may make a difference if your NT is internal or external ... ours is external, which means we can pull the plug between NT & AS/400 & have them run independently.

There is also an issue of validity of other OS objects from perspective of OS/400. We have some SSP objects ... we can backup the entire SSP environment with the rest of our OS/400 backup, but if we want the ability to recover individual SSP objects, we have to do the backup from SSP.

Thus, a total OS/400 backup is good for a total system restore, but most often we have individual libraries files members objects we want to restore & that is not always practical when OS/400 backed up the data of some other OS.
