Physical Harddisks on Adaptec Controllers

Hello,

Software versions: Unix Agent from Github (2.3?), Server as RPM, installed via http://rpm.ocsinventory-ng.org/enterprise repo

On a CentOS6 Machine with an Adaptec controller, the agent reports only the logical (raid) devices instead of the physical devices.

Report says:

sda    sys    disk    999643    SAdaptec_sys_5B98A729    V1.0
sdb    data    disk    999643    SAdaptec_data_5104B729    V1.0

Controller tool says:

# /usr/StorMan/arcconf getconfig 1 PD | grep Serial

As you see, that server has 4 disks, configured as  2 logical devices on the Adaptec Controller. How can we get the actual disks into our invetory? Might be a bug?
