ahc0 cannot see attached devices

[Dan Langille]

I am in the process of moving a tape library from one server to another. 

The old server is running FreeBSD 8.4-RELEASE and using:

ahc0: <Adaptec 2944 Ultra SCSI adapter> port 0xa800-0xa8ff mem 0xfb7df000-0xfb7dffff irq 20 at device 5.0 on pci1


The new server is running FreeBSD 9.1-RELEASE-p4 and using:

ahc0: <Adaptec 2940B Ultra2 SCSI adapter> port 0xe800-0xe8ff mem 0xfebdf000-0xfebdffff irq 21 at device 3.0 on pci4


While the new server boots, I don't see an Adaptec card BIOS prompt / mention pass by on the console.   Is this the first problem to solve?

After booting, I try to view the devices, i don't' see them.  I see the expected HDD, but not the tape library or the drives:

$ sudo camcontrol devlist
Password:
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 2 lun 0 (pass0,da0)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 10 lun 0 (pass1,da1)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 11 lun 0 (pass2,da2)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 12 lun 0 (pass3,da3)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 13 lun 0 (pass4,da4)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 14 lun 0 (pass5,da5)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 16 lun 0 (pass6,da6)
<ATA TOSHIBA DT01ACA3 ABB0>        at scbus0 target 17 lun 0 (pass7,da7)
<TOSHIBA DT01ACA300 MX6OABB0>      at scbus5 target 0 lun 0 (pass8,ada0)
<TOSHIBA DT01ACA300 MX6OABB0>      at scbus5 target 1 lun 0 (pass9,ada1)


If I detach the tape library and attach it to the old server, I do see the expect results (the following paste is missing non-tape related results):

<QUANTUM DLT8000 0250>             at scbus12 target 4 lun 0 (sa1,pass12)
<OVERLAND LXB 0524>                at scbus12 target 6 lun 0 (pass14,ch1)


Ideas?  Suggestions?  Thank you.
