[Linux-PowerEdge] hard disk predictive failures and snmp

Hello List,

I have a few PowerEdge R710s running Ubuntu 12.04 and OMSA 7.1.0-1 which
were reporting disks in 'predictive failure' in OMSA but when queried via
snmp were not indicating any failure.  Because of this our Nagios checks
failed to notify us the disks were predicted to fail and I'm trying to
understand why.

When looking at the Nagios check/script I saw the OIDs it was querying and
the values returned.

iso. = INTEGER: 3 (Online)
iso. = INTEGER: 3 (Online)
iso. = INTEGER: 3 (Online)
iso. = INTEGER: 3 (Online)
iso. = INTEGER: 3 (Online)
iso. = INTEGER: 3 (Online) — This disk
is in predictive failure. Should be '34'.
iso. = INTEGER: 2 (Failed)
iso. = INTEGER: 3 (Online)

The disks have since been replaced so I don't have a way to test this at
the moment however I was hoping someone could provide some insight into why
this may be happening.
