Troubleshooting Disaster Recovery on Windows

'System may not boot after disaster recovery.
If the boot and system volumes are both physically located below 7.8
GB, this error message can be ignored. The boot and system
partitions on Windows NT 4.0 must namely be physically bellow the
first 7.8 GB due to the operating system limitations. Refer to MSDN
Q224526.
Problem Blank Screen During Recovery
Certain system configurations have been encountered where the video
display does not work, if Windows is started in safe mode. This error is
not related to Data Protector and can occur even if only Windows is
installed.
Action If the screen is blank during disaster recovery, this does not mean that
the recovery has failed. You can monitor the progress of disaster recovery
on the Cell Manager or use
ping and telnet 5555 (or appropriate)
commands from another client to see if the target system responds.
Other indicators that the recovery is still in progress are that the device
is working and that hard disk lights are blinking.
If the target system responds to ping and telnet 5555 commands, but
hard disk lights are not blinking and the device is not active, it is
possible that the auto logon failed. Press
Enter to log on using the
administrator’s account with a blank password.
The display on the restored system will then work just as it did at
backup time.
Problem Network is Not Available During Restore
Action Ensure that the problem is not with switch, cables, etc. Another
possibility is also that the DNS server (as configured at backup time) is
offline during the restore. Since the configuration of the DR OS is the
same as at backup time, the network will not be available. In this case
perform offline restore and change the DNS settings after recovery. You
can also edit the registry
(
HKey_Local_Machine\SYSTEM\CurrentControlSet\Services\Tcpip\
Parameters ) before Phase 2 is started. In this case you have to reboot
before Phase 2 for the changes to take effect. After Phase 2 finishes, you
can correct the settings before Phase 3 can be started.
