Hi,

Our test team has one test case, where they need to verify multi lun detect=
ion by FreeBS8.2 OS.
Here are the steps to reproduce.

Step 1: Configured Multi-Luns in RBOD (DOTHILL) and map to controller which=
 is booted with FreeBSD
Step 2: Issue the command "camcontrol rescan all" and "camcontrol dev"

Expected Result: the command should display all the configured luns

Actual Result: Only the first Lun is discovered

Note: When we issue explicit scan using "camcontrol rescan bus:target:lun",=
 it detects that specific lun.

Query: How does FreeBSD detect multi luns ? Driver issue XPT_BUS_RESCAN and=
 expect OS should detect both the luns.
Is there any limitation associated with multi lun in FreeBSD ?


Thanks, Kashyap
