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

Ongoing Maintenance
Certain considerations must be noted regarding the ongoing maintenance of
your system in the recovery process for an MS:
■ 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
■
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 ProCurve Networking
by HP at or for a package to update the license key. In normal
environments however, the license key will update automatically.
■
Rule updates must be applied to both the primary and standby MS (so

■ NAC 800 upgrades must be applied to both the primary and standby
MS
■
Regular backups need to be taken of the primary MS, and stored in a
safe location
