I have a HP Proliant DL380 G7 where I know that there is a physical disk with problems but HPOM is not alarming.
Checking HPOM hwmon module
root@linux:~ # /var/opt/OV/bin/instrumentation/UXMONbroker -check hwmon
Mon Oct 3 09:37:34 2016 : INFO : HPASM not installed, exit
To have it enabled and working, you need hpasmcli installed. It is located on /sbin/hpasmcli

After installing hp-health package, HPOM hwmon module will work properly
