When applying the patch: 26574496, I noticed the error –patch failed due to missing file :

Screening out files not valid for this installation...
Determining valid on-site files...
The following file is missing:
Error reading product file driver files [complete; make tapes]
Error determining valid on-site files
You could download the patch 10178311:R12.CSM.B and manually copy the csm9652361.drv to right folder
And retry the patch deployment
Hope this helps
