I was tasked with upgrading an S8300D from CM 5.2 to 6.2 after all the preparation work on rebooting the S8300D it failed to load of the DVD and I was unable to ping the S8300D. The software was known to be good and I followed the manual to the letter but we ended up aborting the upgrade.
A number of things have come to light since, first if you are using Windows 7 see the Avaya video attached regards IPV4 address duplication and secondly ensure you have an approved Avaya DVD device.
Avaya approved Panasonic Digistor 73082 or 73322 (Comcode: 700406267)
With CM 6 there is no modem remote access or alarm notification, Have seen an issue where the customer has no alarm service configured and regularly received the following platform alarm even the subsequent alarm which may have caused it had cleared.
SME MAJ Far end alarm service is down this alarm.
GAM WRN Alarm service failure – unable to report alarms
Only way I could see of resolving it was by turning off the Master Agent from the CM web page, it has to be done on each server too.
Server (Maintenance) / Agent Status (Under Alarms) click Stop Master Agent.
Unfortunately whenever CM is restarted you have to do it all over again as it restarts the service.
You can also do it from the command line
stop -s MasterAgent (it will ask you to confirm Y and a statapp will confirm is it off).
