An approach is not to monitor the temperatures of the individual disks, but 
to monitor the temperature of the group of disks on a single host. The 
rationale of this approach is that normally one is interested in the range 
of temperature values, combined with an alert if at least one temperature 
is out of range.

I've used this approach to monitor 'the temperature' of a switch. The 
number of temperature sensors per switch varies from 1 to 29 (!). The 
returned value is the minimum, average and maximum temperature, thus always 
three values per switch.

HTH,
   Wim Nelis.
