Having a problem with the mount point for Kernel DVD Upgrade Solman 7.1

Hello Experts,

I am doing an upgrade to Solution Manager 7.1 SR1 from Solman 7.0 EHP1 SP28, when the SOLMANUP tool, asked me about to: Enter at least the mount point containing "Kernel DVD", then I unzip the related object 51042613_10 and give the path of my download directory + SOLMAN_7.1_SR1_Krnl_LINUX_x86_onP_zS_\DATA_UNITS or even with only the SOLMAN_7.1_SR1_Krnl_LINUX_x86_onP_zS_ then the SOLMANUP is telling me that the request data carrier is not mounted on any of the mount points that you entered and that the scope is corrupted, any advice about it, I am teking the wrong object or the path is wrong?, by the way our OS is Linux on x86_64 64bit.

Thanks for your advices,

Paul
