Hello everybody!

I've got a problem with my Oracle-Cluster:
The Read-/Write-Counters for my /dev/md -devices (linux-software-RAID)
and my /dev/vpath -devices (ESS Storage) in the UCD-DISKIO-MIB remain on 
zero.
Net-SNMP lists them under .1.3.6.1.4.1.2021.13.15.1.1 but doesn't notice 
any traffic on
these devices. 

For example:

/vpatha consists of /dev/sdcc, /dev/sdbm, /dev/sdak and /dev/sdu
I can monitor traffic on these 4 devices, but /vpatha remains on zero!


I hope, somebody can help me!

greetings
