Hot Code Activation

[Anonymous]

Has anyone experienced any problems with firmware upgrades and hot code activation not working properly on a 3900? I recently tried to upgrade from 4.1.1a to 4.2.0b and I actually had loss of light and I/O disruption to my hosts connected to the switch I upgraded. Hot Code activation is suppossed to work as no loss of light and no I/O disruption.

We had the same problem when we upgraded from 4.1.1b to 4.1.2e however when we did it (in another switch) from 4.1.2e to 4.2.0b, it was just fine.Fernando
