Hi. Hoping someone can help me with this.  I've tried several times to update the PERC H310 driver on our T320 as recommended/cautioned by OMSA. Every attempt never gets past this message.  I gave the trustedinstaller account full control of system32 & driver/driverstore folders.  The update failed again but on a reboot the server crashed and had to be restored.  A look into the drivers folder shows the new percsas.sys driver version 6.805.3 had actually replaced the previous 5.2.220.64 version and causing the boot sequence to fail.

On  a similar note, I also tried to install a startech USB3.0 add-on card which I noted works on other PE models as well as the T320 but the same 'access denied' error occurred with every install attempt.  I did the same thing with trustedinstaller permissions and have rebooted after this particular process with no boot issues but the driver never did take.

Any help with the PERC issue would really be appreciated.

Thanks.
