Hi netlogix,
I'm pretty sure that this won't help, as we're not importing technology (hardware health - I'm using shortcut HWH for that, ...) pollers in discovery for nodes already in database.
The question is, if there is no HWH under ListResources at all, or just everything is unselected?
If this is the second issue, you can force Orion to run 'background discovery' using following SQL:
INSERT INTO dbo.[NodeSettings] (NodeID, SettingName, SettingValue)
SELECT n.NodeID, 'NeedsInventory', 'HWH'
FROM Nodes n LEFT JOIN APM_HardwareInfo hw ON (n.NodeID = hw.NodeID)
WHERE n.ObjectSubType = 'SNMP' AND hw.NodeID IS NULL
AND n.Description LIKE '%Cisco%'
AND n.NodeID NOT IN (SELECT NodeID FROM dbo.[NodeSettings] WHERE SettingName = 'NeedsInventory' AND SettingValue = 'HWH')
(this forces lazy HWH discovery on all ondes, that doesn't have any HWH poller assigned AND their description contains string 'Cisco'. Feel free to update the SQL accordingly.
But, because you posted in NPM forum, I think that this is the first issue - no HWH pollers are even available. This is because of NPM being able to poll HWH only for network devices, if you want to poll HWH on servers, you need to use SAM.
HTH,
