Update firmware on dl360 gen9 from esxi host software.

I have a remote server with slow internet access.  I need to update the P440AR Smart Array.  Booting the ISO for SPP from the ILO times out and never boots.  I tried to use the install method from the firmware install notes by loading the zip file to the ESXi host.

But I get the error message when executing the file.

Unable to create scratch directory

!!!Error detected ... preserving working files for analysis

Is there a more detailed installation instruction?  

I am not the administrator of the system, just tasked with finding a solution.

Bob
