Enhancement to Generate warning for GISOs bigger than 1.8GB which are not supported #11

Closed mivens closed 2 years ago

GISOs above 1.8GB in size are not supported as per CSCvw23760 and the Limitations section in the Customize Installation using Golden ISO chapter of the System Setup and Software Installation Guide for NCS 5500 (and similarly for ASR 9000). Systems can upgrade successfully using GISOs bigger than 1.8GB but then later run into problems the first time there is a hardware failure and replacement hardware needs to PXE boot to reimage/synchronise its software packages with the rest of the system.

This is an enhancement request so gisobuild refuses to build a GISO bigger than 1.8GB unless a force option is used or generates a warning that needs to be acknowledged for the GiSO build to complete.

Similarly when building GISOs for asr9k platform, warn for GISOs bigger than 1.599GB that they are not supported on RSP880-LT-SE/TR as per System Setup and Software Installation Guide for Cisco ASR 9000 Series Routers.

Support on the NCS5500 for SMUs bigger than 1.8GB was added via the fixes CSCvz19210 and CSCvz33680 (SMUs available for 7.1.2 and 7.2.2).
