NOTE: Only an administrative user needs to be created. Other UI users are migrated as part of the
backup and restore process. Be sure to keep this UI login information safe, as it is Needed to
transition MS services to the standby MS.
F.3 Ongoing Maintenance
Certain considerations must be noted regarding the ongoing maintenance of your system in the
recovery process for an MS:
Š
As part of an ongoing maintenance plan or during backup, check the status of the NAC-
testscripts RPM by entering the following from the command line:
rpm -q NAC-testscripts
Š
If changes are made to the license without an internet connection (such as increasing the
number of ESs or endpoints), you will need to make changes to the standby license as well. For
a license without an internet connection you will need to contact
Novell Support (http://
www.novell.com/support) (800-858-4000) for a package to update the license key. In normal
environments however, the license key will update automatically.
Š
Rule updates must be applied to both the primary and standby MS (so they have the same
version)
Š
Novell ZENworks Network Access Control upgrades must be applied to both the primary and
standby MS
Š
Regular backups need to be taken of the primary MS, and stored in a safe location
F.4 Failover process
Once a standby MS is established for MS recovery and all system requirements and ongoing
maintenance issues are addressed, begin the MS recovery as follows:
To migrate MS duties to the standby MS:
1 Log into the primary MS as
root
using SSH or directly using a keyboard.
2
Shutdown the primary MS server by entering the following from the command line:
shutdown -hy 0
3 Locate the most recent backup of the primary MS. See “Restoring to a new Server” on
page 339 . This will be the backup that you were instructed during initial installation to store in
a safe place .
4 Copy the backed up file of the primary MS to a Personal Computer (PC) with access to the
standby MS. See
Section 1.9, “Copying Files,” on page 28 .
5
Log into the UI of the standby MS.
6 Navigate to System configuration>>Maintenance
7 Click the
restore system from backup
to upload the primary MS backup file. See
Section 16.7.2, “Restoring from Backup,” on page 339 . Wait for the restore to complete.
8 Log in to the standby MS as
root
using SSH or directly using a keyboard.
