2.5.51 + fastT FC disk

Hi,

We tested 2.5.51 on a ppc64 box, qlogic 2312 and a fastt700 array. I had CONFIG_SCSI_REPORT_LUNS and unfortunately it thought the management LUN was a disk:

Vendor: IBM Model: Universal Xport Rev: 0520
Type: Direct-Access ANSI SCSI revision: 03

...

SCSI device sdaj: drive cache: write through SCSI device sdaj: 40960 512-byte hdwr sectors (21 MB)
sdaj: unknown partition table
Attached scsi disk sdaj at scsi2, channel 0, id 0, lun 31

...

end_request: I/O error, dev sdaj, sector 0

Three years later...

It looks like SGI use the same FC vendor and they already have a workaround for this issue. The following patch adds the IBM version of it.
