Dell PowerVault 124T issues

Hi,

Today I got a new PowerVault 124T with LTO-3 drive.

First of all:

[root@nuts rz]# mtx -f /dev/sg2 inquiry
Product Type: Tape Drive
Vendor ID: 'IBM     '
Product ID: 'ULTRIUM-TD3     '
Revision: '5BG2'
Attached Changer: No

Why is the vendor IBM? Shouldn't it be Dell?

[root@nuts rz]# mtx -f /dev/sg7 inquiry
Product Type: Processor
Vendor ID: 'DELL    '
Product ID: '1x4 U2W SCSI BP '
Revision: '1.16'
Attached Changer: No

The Tapelibrary is attached to:

02:04.1 SCSI storage controller: Adaptec AIC-7899P U160/m (rev 01)

Otherwise dmesg says this (note that on the same card but channel A, an
older PowerVault 120T is attached that is working fine)

I'm a bit confused about all these devices. I can't communicate with my PV
124T either on /dev/sg2 nor on /dev/sg7.
