7767
Required system image parameters missing.
Cause. SYSGEN started BACKUP to create a system image tape but failed to provide one or more
of the parameters that BACKUP requires for this operation, probably because incompatible versions
of SYSGEN and BACKUP are being used.
Effect. BACKUP terminates without writing a system image tape.
Recovery. Run SYSGEN again, either directly or through Install, after ensuring that the SYSGEN
phase of the installation process starts a compatible version of BACKUP.

Cause. An attempt was made to restore individual partitions from a tape that contains entire

incompatible.
