When upgrading a DCA v2 ISO from 184.108.40.206/220.127.116.11 to ISO 18.104.22.168, 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
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 22.214.171.124 code install.
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
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.
