Upgrade of DCA ISO from 2.0.3.0/2.0.4.0 to ISO 2.1.0.0 precheck failes for missing files

Issue

When upgrading a DCA v2 ISO from 2.0.3.0/2.0.4.0 to ISO 2.1.0.0, the precheck stage will fail due to missing files with the error messages similar to the following

CreateGoldenFile: /opt/dca/var/cdrom/GP/dia24_pxe.cfg, 376 of 427 failed: golden file and target file not found: /opt/dca/var/cdrom/GP/dia24_pxe.cfg 

This error message can occur for 9 files. There are 6 files on the master that will give this type of error:

/opt/dca/var/cdrom/GP/dia24_pxe.cfg
/opt/dca/var/cdrom/GP/dia24_usb.cfg
/opt/dca/var/cdrom/GP/external/dia24_pxe.cfg
/opt/dca/var/cdrom/GP/external/dia24_usb.cfg
/opt/dca/var/cdrom/GP/smdw/dia24_pxe.cfg
/opt/dca/var/cdrom/GP/smdw/dia24_usb.cfg 

There are 3 files on the Standby that will give this type of error:

/opt/dca/var/cdrom/GP/dia24_pxe.cfg
/opt/dca/var/cdrom/GP/external/dia24_pxe.cfg
/opt/dca/var/cdrom/GP/smdw/dia24_pxe.cfg 

Workaround

The workaround for this issue is to touch all of these files in the respective directories. These files are not required during the upgrade and will be over written by the 2.1.0.0 code install.

On master:

touch /opt/dca/var/cdrom/GP/dia24_pxe.cfg 
touch /opt/dca/var/cdrom/GP/dia24_usb.cfg
touch /opt/dca/var/cdrom/GP/external/dia24_pxe.cfg
touch /opt/dca/var/cdrom/GP/external/dia24_usb.cfg
touch /opt/dca/var/cdrom/GP/smdw/dia24_pxe.cfg
touch /opt/dca/var/cdrom/GP/smdw/dia24_usb.cfg

On Standby

touch /opt/dca/var/cdrom/GP/dia24_pxe.cfg
touch /opt/dca/var/cdrom/GP/external/dia24_pxe.cfg
touch /opt/dca/var/cdrom/GP/smdw/dia24_pxe.cfg 

Note:

If the precheck stage is not run and you get these error messages during the upgrade, the above steps can be followed to resolve this issue. Then run the upgrade again.
