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
