Good day to everyone!
We are going to upgrage software on our two 10508 boxes (IRF mode) from version 7.1.0-R7180 to 7.1.0-R7536P05. In Release Notes we found next statement and would like to know what does it mean?
Restriction 3
In an IRF fabric with plenty of configurations, the system might take more than half an hour to collect
the diagnosis information.
We cannot use ISSU (because software versions are incompatible), so our plan is pretty simple - copy BOOT and SYSTEM binary files to linecards #4 and #5 on both boxes, correct boot-loader, save and reboot.
Our IRF stack has plenty of configurations, so what will happen after reload? Will our switches become out-of-service just for the ~5 minutes, needed for reload, or for half an hour, as written above?
Also, please, provide us any caveats on this procedure.
Thanks a lot in advance! :)
