what does mksysb do?

Stan - from the AIX man page for mksysb:

Description

The mksysb command creates a backup of the operating system (that is, the root volume group). You can use this backup to reinstall a system to its original state after it has been corrupted. If you create the backup on tape, the tape is bootable and includes the installation programs needed to install from the backup.

The file-system image is in backup-file format. The tape format includes a boot image, a bosinstall image, and an empty table of contents followed by the system backup (root volume group) image. The root volume group image is in backup-file format, starting with the data files and then any optional map files.

One of the data files mksysb uses is the /bosinst.data file. If a /bosinst.data file doesn't exist, /var/adm/ras/bosinst.data is copied to / (root). In AIX
4.3.3 and later versions, mksysb always updates the target_disk_data stanzas in bosinst.data to match the disks currently in the root volume group of the system
where the mksysb command is running.

Quite a useful utility, which we've used on occasion to recover systems.

OK, no such beast in Openserver.
There is a backup section in scoadmin with minimal functionality (actually never used it).

I usually do it manually with cpio and root/boot diskettes
( see faq58-932 ).
or use one of the supertars (lonetar, backupedge....)

I personally use a custom mkdev fd like script for creating boot/root diskettes and a customised version of gnutar -g (and -d for verif) for FileSystems.
