I just notice that, since I flashed the card (A Dell H200) to so-called "IT Mode" it doesn't show the expanders.

This is what I saw before flashing the card:
Feb 12 10:01:33 pruebassd kernel: ses0 at mps0 bus 0 scbus0 target 3 lun 0
Feb 12 10:01:33 pruebassd kernel: ses0: <DP BP12G+ 1.00> Fixed Enclosure Services SCSI-5 device 
Feb 12 10:01:33 pruebassd kernel: ses0: 150.000MB/s transfers
Feb 12 10:01:33 pruebassd kernel: ses0: Command Queueing enabled
Feb 12 10:01:33 pruebassd kernel: ses0: SCSI-3 ENC Device

And now, same hardware, different firmware, I don't see the "ses0" expander, odd.

Anyway, I pulled one of the disks (physical slot 4) and it wasn't the disk identified by sas2ircu as connected to "1:4" but
a different one.

That I mean. Chaos... ;)
