On Tue Aug 21, 2012 between 5:00-7:00am, the production Infoblox grid for the campus IPAM (DNS and DHCP) service will be upgraded from its current software version (6.4.2) to the latest release from the vendor (6.5.0).
What's new:
- The CSV Import feature is now available to non-superusers.
- several under-the-hood improvements, including fixes for two recent ISC DHCP vulnerabilities
How will services be affected during the upgrade window?
- During the upgrade window, IT Professionals will not be able to log in to Grid Manager (via the GUI or the API) to make DNS and DHCP configuration changes.
- Any Scheduled Tasks created in Grid Manager that have not completed before the upgrade begins will be automatically removed.
- Due to the use of DHCP Failover and the fact that the appliances upgrade sequentially, clients will in general still be able to obtain DHCP leases during the upgrade window. However, if a particular DHCP Range is very nearly full and experiencing a lot of churn (old clients leaving and new clients joining the network) during the upgrade window, it is possible that some new clients joining that range may not be able to obtain leases until both servers are back online.
- DNS query resolution is NOT impacted by this change.
If you would like to preview the new software version prior to the upgrade date, you may log into the dev grid at https://ipam-dev.illinois.edu/
Please contact hostmgr with any questions or feedback.
Important Reminder for API Users
After the upgrade date, you will need to update your installation of the Infoblox API perl modules on any client systems that you use to run Infoblox API scripts against the production grid. Note that this upgrade cannot be applied to your production environments ahead of time; see the service documentation (http://www.cites.illinois.edu/ipam/api.html) for further explanation.
We recommend that you set up a test environment prior to the upgrade date to verify that your API scripts will work as expected against the new software version. You can download the new perl modules from
https://ipam-dev.illinois.edu/api/dist/CPAN/authors/id/INFOBLOX/Infoblox-6.0050000175312.tar.gz
Be sure that your test scripts specify (master => "ipam-dev.illinois.edu") when creating a Session.
