unable to create/delete array from LSI card using megaraid, megarc

[javocado]

I'm running 6.2-R and have installed linux-megamgr and megarc from
ports. Both utilities run fine, but neither will allow me to add or
remove an array from the system (I have to do it via the BIOS
utility). Relevant parts:

# dmesg |grep amr
amr0: <LSILogic MegaRAID 1.53> mem 0xdf200000-0xdf20ffff irq 72 at
device 1.0 on pci8
amr0: delete logical drives supported by controller
amr0: <LSILogic MegaRAID SCSI 320-1> Firmware 1L47, BIOS G121, 64MB RAM
amr0: delete logical drives supported by controller
amrd0: <LSILogic MegaRAID logical drive> on amr0
amrd0: 70006MB (143372288 sectors) RAID 1 (optimal)
amrd1: <LSILogic MegaRAID logical drive> on amr0
amrd1: 140013MB (286746624 sectors) RAID 1 (optimal)

Is this normal, or do I have a misconfiguration?

Thanks.
