On both IOP disks access the partitions from the CE using the virtual network—a feature first
available in V2.2.0. Remember that the virtual network is slow, so plan the time when this is
done to have minimal impact to users.
After each successful update to the CE OS, use Marathon's MTCCPYNT utility to "clone" the
current (running) CE root as the "emergency recovery copy". (Browse the marathon CD ROM
and run z:\support\mtccpynt c:\winnt x:. If using the IOP disk alternative, one mtccpynt (of two)
must be targeted at each IOP.
Note when performing updates to the emergency recovery copy, you will be prompted to
overwrite existing directories. Answer yes in all cases.
Repeat the above procedure each time your would otherwise update your NT Emergency Repair
Disk.
4. TO RECOVER the CE OS USING AN EMERGENCY RECOVERY COPY
The CE is down already (it cannot be booted, due to the problem we are recovering from).
Choose the IOP best suited to support the recovery and reboot it into Marathon Off-line Mode.
(Choose an IOP that is known to have a good copy of the CE BOOT DISK.)
Determine the drive letter where the CE OS resides. (D: for purposes of the following
discussion).
Determine the drive letter where the EMERGENCY RECOVERY COPY exists (X: for purposes of
the following discussion.)
Determine the pathname where mtccpynt.exe can be located (CD-ROM Z:\support for purposes
of the following discussion.)
Execute mtccpynt to reverse the procedure that created the EMERGENCY RECOVERY COPY.
(Browse the marathon CDROM and run z:\support\mtccpynt x:\winnt d:). (Note that during the
copy process you will be prompted to overwrite existing directories (except if the disk is empty).
Answer yes in all cases.)
Perform a Marathon software installation for the CE ONLY while operating on the IOP (in off line
mode).
1. Select Endurance Software Installation
2. Check CE and explicitly un-check IOP
3. When prompted for the location of the CE root browse or enter d:\winnt (the target of the
mtccpynt command - and the CE_BOOT device).
4. If prompted to overwrite files that are newer on disk - choose NO for all files that begin with
"mtc". Such files are Marathon components that have been upgraded via a hotfix installation.
By choosing NO it will not be necessary to reapply the Marathon hotfixes.
Reboot the IOP(s) in Operational Mode
The CE WILL NOW BOOT!
Consider performing the appropriate series of restore operations (from your most recent backups)
to bring the disk up-to-date.
