TFTP and BuildDuration time

Unanswered Question
Nov 30th, 2007

Cisco 4.x SRND states the following regarding upgrade the tftp server. Anybody knbows what Cisco TFTP - BuildDuration time is? A tool? thanks

When upgrading a Cisco Unified CallManager cluster, Cisco highly recommends that you upgrade the TFTP servers after the publisher and before any other server, also allowing additional time following the upgrade for the TFTP server to rebuild all the configuration files. Either use the typical Cisco TFTP - BuildDuration time or use the real-time monitoring tool to monitor the Cisco TFTP - DeviceBuildCount until it stops incrementing.

I have this problem too.

What is being suggested is that prior to upgrading other servers in the CUCM cluster, that you either monitor the Windows Cisco TFTP BuildDuraction perfmon counter or the RTMT DeviceBuildCount until they stop incrementing.

Once they have stopped then you can be assured that all the configuration files have been created. Do you have a separate TFTP server, or is enabled on the Publisher? Either way monitor either counter when it stops the proceed with upgrading the remaining servers in the cluster.

Hope this helps.
