6500 series having a single sup2/msfc2 with pure IOS
I've understood that if we hot insert another sup2/msfc2 with pure IOS even with different version, the IOS in the active sup engine, along with the configuration will be automatically downloaded to the new (standby) supervisor engine.
My quetion now is, what will happen if the hot inserted sup engine is having a hybrid OS.
The IOS image will not get synchronised with Native IOS, the config will unless you manually disabled RPR(+). You will need to manually copy the IOS image onto the new Supervisor2/MSFC2 and set the boot parameters - its quite easy.
With CatOS (Hybrid) the Code is synchronised between the 2 Supervisors (unless High-Availability Redundancy and Versioning are enabled). The second supervisor must be able to boot initially though as the version is checked once the supervisor is booted.
As I said before, with Hybrid code (CatOS running on the Supervisor and IOS running on the MSFC) CatOS code will be synchronised if a new supervisor is inserted and sucessfully boots a version of CatOS. The logic works by the Active Supervisor checking what is running on the standby supervisor when it comes onlinel; if the versions are different then the Active Supervisor will initiate a copy of its running code to the Standby Supervisor, then set the Standbys boot variables and then finally reload it. The MSFCs will NOT synchronise their code you MUST do this manually.
With Native IOS (single IOS image controlling both the Supervisor and the MSFC) the IOS image is NOT automatically synchronised; the configuration is synchronised, so, the 'boot system flash:xxxxxxx' environmental variable will be synchronised but the code MUST BE MANUALLY COPIED. You can do this from the Active Supervisor as you have access to the flash of the Standby supervisor once it has booted.
