Disaster Recovery Procedural Overview

The procedure described in this section for responding to a catastrophic event is

general in nature and may result in the loss of data. Should such an event actually

occur, the exact procedure to follow will vary according to environmental

conditions. Adaptec strongly recommends that you contact a technical service

representative before proceeding.

This section describes a worst-case scenario:

•

The operating system has failed, (e.g., due to a malicious attack to the root file

system), and you cannot access the server.

•

The data has been corrupted and must be restored from tape.

•

Technical support has deemed your server unsalvagable and provided you with

a new, unconfigured server.

Restoring Previous Server Settings to a New Server

After Technical Support has supplied you with a new server, you can restore the

settings from the previous server to the new server. Any third-party license keys

you have not purchased through Adaptec will be lost. If you have installed data

replication or management utilities such as Snap EDR, you will need to re-install

and/or relicense them for use with the new server.

Note

If you are restoring EDR Management Console settings, you must recreate the

RAID and volume configuration that matches the DRI settings, then install and

enable the EDR Management Console. As an alternative, you can first restore just

the system settings, install EDR, and then restore just the EDR settings.

You will also need to reschedule snapshots as well reconfigure CA Antivirus.

Note

If you are restoring the DRImage to the same server, all your license keys

should be intact. You will still need to reschedule your snapshots and CA Antivirus.

When you connect to the new server, navigate to

Maintenance > Disaster

Recovery

, select

Recover System Setting

and click

Click the

Browse

button and navigate to the Snap DRImage you made of the

previous server, then click

The server will reboot and the settings will be restored. To view the log, click the

date link on the Disaster Recovery screen after the server has rebooted.

After restoring your server settings, rejoin the server to the Windows domain if

necessary.
