HP NetServer AA 6-12 2. Minor Repair Using An IOP In Off Line Mode Use an IOP in offline mode to invoke the repair to the CE BOOT disk - then force a mirror copy in the proper direction as you recover. The steps are: a. Choose an IOP to undertake the repair on the CE BOOT device (cannot be the unfinished target of a mirror copy) b. Reboot the selected IOP to MARATHON OFFLINE MODE (the server already is down/cannot be rebooted - or you would repair it from the running CE OS). c. Replace the driver or delete the service - or otherwise make repairs to the CE BOOT device. d. Perform a Marathon software installation for the CE ONLY while operating on the IOP (in offline mode). • Select Endurance Software Installation • Check CE and explicitly un-check IOP • When prompted for the location of the CE root browse or enter d:\winnt (or an alternative pathname that defines your CE OS). • 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. e. Reboot the IOP(s) in Operational Mode f. Boot the repaired CE OS. The CE WILL NOW BOOT (if the proper repair was made)!! 3. Restore A Saved Copy Of Windows NT Prepare and maintain an EMERGENCY RECOVERY COPY of the CE OS.

Minor Repair Using An IOP In Off Line Mode
Use an IOP in offline mode to invoke the repair to the CE BOOT
disk - then force a mirror copy in the proper direction as you
recover.
The steps are:
a.
Choose an IOP to undertake the repair on the CE BOOT
device (cannot be the unfinished target of a mirror copy)
b.
Reboot the selected IOP to MARATHON OFFLINE MODE
(the server already is down/cannot be rebooted - or you
would repair it from the running CE OS).
c.
Replace the driver or delete the service - or otherwise make
repairs to the CE BOOT device.
d.
Perform a Marathon software installation for the CE ONLY
while operating on the IOP (in offline mode).
•
Select Endurance Software Installation
•
Check CE and explicitly un-check IOP
•
When prompted for the location of the CE root browse
or enter d:\winnt (or an alternative pathname that defines
your CE OS).
•
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.
e.
Reboot the IOP(s) in Operational Mode
f.
Boot the repaired CE OS.
The CE WILL NOW BOOT (if
the proper repair was made)!!
3.
Restore A Saved Copy Of Windows NT
Prepare and maintain an EMERGENCY RECOVERY COPY of
the CE OS. Use an IOP in offline mode to invoke a recovery,
then force a mirror copy in the proper direction to recover.
Re-
apply the tape backups to bring the system to a fully consistent
state.
Marathon provides a tool (normally used during installations)
that supports this procedure.
MTCCPYNT.EXE is located on
the AA 4000 CDROM and can be used to “clone” the running
NT installation to another disk partition for safe storage. (See
Marathon Endurance 4000 User's Guide, Chapter 6-Marathon
tools and utility.)
If necessary it can be used to reverse the copy
direction and therefore restore a disk to the state that was most
recently saved.
There are limitations to this approach, just as there are when
depending on Emergency Repair Disks (ERDs).
