CMK 1.6.0.p1 has several idrac snmp checks shipped by default, and one of them is for raid monitoring.
Can’t you use them ?
SNMP Checks shipped with CMK in 1.6 version :
dell_idrac_disks
dell_idrac_fans
dell_idrac_power
dell_idrac_raid
dell_idrac_virtdisks
So, can you do a snmpwalk towards your idrac server for these OID ?
.1.3.6.1.4.1.674.10892.5.5.1.20.130.1.1.1
.1.3.6.1.4.1.674.10892.5.5.1.20.130.1.1.2
.1.3.6.1.4.1.674.10892.5.5.1.20.130.1.1.38
And tell me what you get when you do a snmpwalk for this OID : .1.3.6.1.2.1.1.2.0
If it starts with .1.3.6.1.4.1.674.10892.5 you should get CMK to monitor you RAID in your iDrac and avoid to use “thirdparty” plugins.
Cheers,
