HP recommends these tools be installed for ESX 4, however here are the install instructions.
Login as the system administrator (root), download the package to a directory on your hard drive. Navigate to that directory and unpack the contents of the package by typing:
• tar -zxvf hpmgmt-8.4.0-vmware4x.tgz
This will create two new directories (./hpmgmt and ./hpmgmt/840) under the current directory. Navigate to the ./hpmgmt/840 directory and view the README file for installation instructions.
I know nothing about using or getting around in linux, so have no idea how to get to a directoy (temp) that I uploaded the files to via vCenter. So in vCenter, I have created a new direcory called temp, and then uploaded the file to it. Can someone pass along directions to cd to temp?
