Uses SSH to fetch information from the unit.

Built and tested on a Dell DR4100 unit, software version 3.2.0802.3
My unit has no errors currently but best effort is taken to simulate them.

Will raise WARNING condition on most hardware or array based faults.
Temperature tresholds can be set as variables in the script.

Requires 'sshpass' to function. Please install it before running this script.
