Best practices for restoring an appliance

Topic Best Practice
Before you begin
  1. Note the passwords you use.

    Maintain a list of the current user accounts on the appliance.

    The restore operation resets the user names and passwords to those that were in effect when the backup file was created.

  2. Create a support dump.

    Use the support dump to diagnose failures that occurred before the restore operation.

  3. Download the existing audit logs, and store them for safekeeping.

    The restore operation restores the audit logs from the backup file, overwriting the existing logs.

  4. Stop all automatically scheduled backups.

    Restart the automatically scheduled backups after the appliance is restored.

  5. Make the backup file accessible to the appliance from which you plan to issue the upload request. If you are using an enterprise backup product to archive backup files, follow any steps required by your backup product to prepare for the restore operation.

Inform users
  • Make sure that all users logged in to the appliance log out. Users who are logged in when the restore operation begins are automatically logged out, losing whatever work was in progress. All users are blocked from logging in during the restore operation.

Use the right backup file
  • Use the latest backup file to restore the appliance. Changes made after the backup file is created cannot be saved.

  • Ensure that the appliance being restored and the appliance on which the backup file was created have the same firmware version; otherwise, the restore operation fails.

    The platform type, hardware model, and the major and minor numbers of the appliance firmware must match to restore a backup. The format of the appliance firmware version is as follows:

    majornumber.minornumber.revisionnumber-buildnumber

    The revision and build numbers do not need to match.

    If the backup file is incompatible with the firmware on the appliance, the upload returns an error and the restore operation stops. You will need to update the firmware or select a different backup file.

  • If you are performing a restore operation on a new appliance:

    • Install the new appliance as described in the Insight Control server provisioning Installation Guide available at www.hpe.com/info/insightcontrol/docs

    • Make sure that the network settings are the same as the original appliance.

  • If the backup file was created on an appliance that is different from the one you are restoring, do one of the following:

    • Delete the original appliance.

    • Reconfigure the original appliance so that it no longer manages the devices it was managing when the backup file was created. Serious errors can occur if multiple appliances attempt to manage the same devices.
