Thanks. This really puzzled me, because snmpwalk returned all the output
needed, while my plugin didn't seem to fetch the needed values.

Fortunately, I was able to reproduce this on a local 2650, which makes
debugging much easier. It turns out that when using
Net::SNMP::get_entries() to fetch the values, there will sometimes be a
whitespace in the OID field of the data returned, while
Net::SNMP::get_table() is OK. I really want to use get_entries(), which
is significantly faster on servers with lots of physical disks.

I have patched check_openmanage so that any excess whitespace is removed
from the OID field before it is analyzed, so get_entries() can still be
used. A beta version is available (check_openmanage-3.5.5-beta4) here:

  http://folk.uio.no/trondham/tmp/

This beta also addresses the controller identification for physical
drives, where the controller id was reported as '-1'. On older hardware
such as the 2650 and 750, the controller to which a physical disk is
attached is not available as a connection to the enclosure, because no
enclosure exists. The plugin will now probe for this information via the
channel connection as well, which provides this info. This only implies
that I probe an additional OID for this information.

Please try this beta version and report your results.

Cheers,
