MS Disaster Recovery
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 Technical Assistance Center (TAC) at (800)
998-2408 or support@extremenetworks.com 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 they have the same version)
●
Sentriant AG 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
●
Failover process

maintenance issues are addressed, begin the MS recovery as follows:

NOTE
Before shutting down or restarting the MS, contact Technical Assistance Center (TAC) at (800) 998-2408 or
support@extremenetworks.com to clear the license secret key so that the original license can be used.
