Compatibility issues:

•

STORE/RESTORE

If files stored from MPE/iX 7.5 are restored to a machine with pre-7.5 OS, the following warning message may appear.

This is due to the $SYSTEM_MASTER interpretation (explained above) and can be ignored. However, the files that show

this warning will be restored and restored on LDEV1.

COULD NOT BE RESTRICTED TO THE SYSTEM MASTER VOLUME

•

SYSTEM REBOOT after MPE/iX 7.5 Installation/Update

During the first boot after install/update of this version, the following message may appear on the system console: (the

system reports that it is mapping the entire LDEV 1 disk capacity for use):

"relocate ssm map to(in sectors) #####"

"To map to the full disk size ###### in pages"

Backdating your system

Important Details Please Read

When backdating from MPE/iX 7.5 version (or later) to a previous version of MPE/iX(like 6.0, 6.5 or 7.0), it is critical to

realize that this enhancement is not available in any of these pre-7.5 versions. Hence, these pre-7.5 versions of the operating

system cannot differentiate whether the files are within the first 4GB of LDEV 1 or beyond it. After backdating, pre-7.5

versions of the operating system will still be able to access the entire capacity of LDEV 1 and start filling the disk from the

beginning of the available free space. As a result of this, system utilities such as START and INSTALL may be stored in the

disk space beyond the first 4GB. At that point, the system will not BOOT. A reinstall of the system from the pre-7.5 backup

would then be required.

However, once the system is able to boot after the backdating, the entire disk is available for the operating system and entire

disk files are available for use.

RECOMMENDATION if backdating from 7.5 to an older release:

It is highly recommended that the user performs an INSTALL from the pre-7.5 backup instead of

backdating or that the user performs a full backup, INSTALL a pre-7.5 version and then restore from the

backup.
