Problem

“No Operating System Found”

Action

After performing disaster recovery, if the final boot of a Windows NT
system fails with “

No Operating System Found

”, check the

boot.ini

file for information about where the partition information is located. See
Step 4 in the section “Recovery” on page 461 for additional information.

Problem

Disk Delivery Disaster Recovery of a Media Agent Client

If you are performing a Disk Delivery disaster recovery, Data Protector
first tries to connect to the original client where the backup device was
attached (Media Agent client) in order to use the same device for restore.
However, when you are performing Disk Delivery disaster recovery of
the crashed Media Agent client where the backup has been made, Data
Protector will not be able to connect to it and will proceed with offline
restore and search for a local device for the restore. If there is no local
device attached, Data Protector will issue a notification that there is no
local device attached and will abort the disaster recovery.

Action

There are three methods to avoid this:

• Move the media to another pool. This way you assign the media to the

new device. Then proceed with Disk Delivery disaster recovery.

• The third method involves preparation prior to the disaster. If you

have two Media Agent clients in the cell, you can back up of the first
Media Agent client to another and vice versa before the disaster to
avoid problems when performing Disk Delivery disaster recovery of a
Media Agent client.
