an mps probelm

[Gregory Wright]

Hi,

I have an LSI SAS 9200-8e hba card.  It's connected to a Dell
PowerVault 124T autoloader with an LTO4 drive.

I installed 9.0-BETA1 yesterday and was able to successfully
detect the tape drive (mps driver), but the hba doesn't find the changer.
I used camcontrol to force rescanning all luns but that
didn't help either.

Since I have just acquired this hardware I installed an OS
reported to work with this autoloader/hba combination,
ubuntu 11.04 server.  On ubuntu, the changer is found:

gwright at greenhouse-george:~$ lsscsi -g

[6:0:0:0]    cd/dvd  MITSUMI  CD-ROM SR244W    T01A  /dev/sr0  /dev/sg4

(On ubuntu the driver is mpt2sas.)

It seems as if the mps driver is not seeing the additional lun
hanging off the bus.

This server is not in production yet so I can re-install 9.0-BETA1
and run more tests, if that would help.

FWIW, I set hw.mps.0.debug_level=1.  In the dmesg I get

Please let me know what I can do to help debug this.
