Saving Files That You Do Not Want Deleted
by the Upgrade
Archived files that were saved with the _OLD extension and
any files you might have added or modified in the SYS$EFI.SYS boot
partition are deleted by the upgrade procedure. You can save these
files from being deleted, as explained in the following subsections.
Saving
Archived Files By default, the upgrade procedure deletes files that were
archived as filename.extension_OLD by OpenVMS remedial
kits. If you do not want these files deleted, you can rename them
before you perform the ugprade. Alternatively, you can have the
upgrade procedure save them by responding to the prompts as explained
in
Saving Archived Files.
Saving
Files Added or Modified in the SYS$EFI.SYS Boot Partition When you upgrade the system disk, the upgrade removes the
old SYS$LOADABLE_IMAGES:SYS$EFI.SYS file and replaces it with a
new one. SYS$LOADABLE_IMAGES:SYS$EFI.SYS is the storage area for
the boot partition used by the Integrity server EFI console. Any
files that were in this partition before the upgrade are lost.
Thus, in the unlikely event that you have added or modified files
in the boot partition (you would have used EFI commands to make
these changes), you must first store copies of these files off
of the system disk before completing the upgrade, and then copy
them back to the partition after the upgrade is complete. Be careful
not to confuse these files with any boot options that you might
have added or modified in the EFI Boot Manager menu; the boot options
are entirely separate from the boot partition and are not removed
by upgrades.
Note that the upgrade procedure displays a message warning
you about the possibility of losing the files. If you have not
saved the files, you can stop the procedure at that point and save
them. Refer to
Choosing Whether to Save Files in the SYS$EFI.SYS Boot Partition.
