OS/2
Summary:
Currently, there is no way to return to disk mirroring or duplexing
after unmasking an orphaned drive in LAN Manager version 2.00 without
reinstalling OS/2 and LAN Manager.
More Information:
Consider the typical scenario where the partition being mirrored goes
bad. Physical disk 0 has a D partition that is mirrored by a secondary
external hard disk. The D partition on physical disk 0 is then
inflicted by some critical error that cannot be corrected without
repartitioning and reformatting it. Since the D partition has an exact
duplicate on the external drive, the duplicate is unmasked and
replaces the former D partition on the primary drive.
Now, consider that the bad partition on the primary drive has been
repaired and can now be put back into service. Without backing up the
files mirrored by the external hard disk onto another drive, it is
impossible to remirror drive D with the external hard disk, since both
partitions are reformatted during disk mirroring setup.
Backing up the files may not be a problem if the mirrored partition
was not that large; however, if the mirrored partition was, for
example, 150 MB, not only would you need to find a hard disk or tape
drive with 150 MB of free space, you must go through the time
consuming process of reinstalling.
