Get webhook notifications whenever Network & Infrastructure creates an incident, updates an incident, resolves an incident or changes a component status.
After the incidents on the first ACE couple (model ACE20), we are going to migrate all the contexts to a new generation ACE couple (ACE30).
The intervention will take place this Monday 14th of May starting from 23:00. The operation will be transparent for the redundant contexts (99% of the cases).
*** Details of the operation ***
1. switch of all the contexts on the ACE-1 of rbx-s1
2. complete back up of the ACE-1 of rbx-s2
2. isolation of the ACE-1 of rbx-s2
3. restarting of the new ACE (ACE-3) in rbx-s2 with the back up of the ACE-1
4. progressive switch of the contexts of the ACE-1 of rbx-s1 to the ACE-3 of rbx-s2
5. back up of the ACE-1 of rbx-s1
6. isolation of the ACE-1
7. restarting of the new ACE-3
8. repartition of the contexts on the 2 new ACE30
Update(s):
Date: 2012-05-20 01:49:03 UTC It's up.
Date: 2012-05-20 01:48:44 UTC We are establishing the 2nd ACE30. it's done. We're waiting.
Date: 2012-05-20 01:48:04 UTC We have rebooted 2 new ACE30. Everything is fine.
Some basic checks. No problem.
We are cutting both old ACE20. Waiting 5 seconds.
Well, it is not cut. Okey, the s1 and s2 setting are not the same. Now, it is cut.
We are establishing ACE30 on s1. it responds to ping. websites are still inaccessible, we need to give MAc time to update it. We're waiting. Websites are up.
Date: 2012-05-19 20:39:33 UTC We put the contexts on the original ACE in their original configuration.
Study in progress with Cisco.
Date: 2012-05-19 20:38:30 UTC The ACE30 does not want to restart!

Date: 2012-05-19 20:37:56 UTC Back up in progress of ACE-1 of rbx-s1 and then restarting of the new ACE30 (ACE-3)
Date: 2012-05-19 20:37:16 UTC Due to the perturbations of this afternoon, we are going to do the switch today.
Right now all the contexts were switched to rbx-s2.
Date: 2012-05-19 20:36:27 UTC We checked the incompatibel contexts one by one.
There is no obstacle to the switch which is planned on Monday May 21st starting from 23:00.
Date: 2012-05-15 05:46:57 UTC All have been reset.
We are going to correct the contexts with a compatible setting then replan the maintenance.
Date: 2012-05-15 05:45:12 UTC There are several contexts with a setting non compatible to the software version on ACE30.
We are going backwards (back to ACE20) time to correct the non valid settings.
*** DETAILS ***
In the previous versions, in a 'class map', it was possible to associate a command 'match any' with other types of commands 'match'.
In the current version (recent major version), this is not possible ('match' criteria will be ignored).
Date: 2012-05-14 21:45:19 UTC The ACE-1 card of rbx-s1 is isolated. We are restarting the ACE30 with the good configuration.
Date: 2012-05-14 21:44:24 UTC The contexts are all on rbx-s1.
