Netapp disk shelves

Does anybody have experience connecting old Netapp disk shelves to a Fibre
channel HBA on a linux system.
i get /dev/sdc (block device)  as well as /dev/sg2 (char device)


-----------------from dmesg ----------------------------------------
  Vendor: NETAPP    Model: X272_HJURE073F10  Rev: NA14
  Type:   Direct-Access                      ANSI SCSI revision: 03
sdc : unsupported sector size 520.
SCSI device sdc: 0 512-byte hdwr sectors (0 MB)
sdc: Write Protect is off
sdc: Mode Sense: db 00 10 08
SCSI device sdc: drive cache: write through w/ FUA
sd 2:0:0:0: Attached scsi disk sdc
sd 2:0:0:0: Attached scsi generic sg2 type 0
-----------------from dmesg ----------------------------------------


The problem i encounter is that the disks report a 520 byte sector size.


"sg_format --format --size=512 /dev/sdc" should fix this,  (or should the
device be /dev/sg2)
Has anyone done this?

Can sg_format --format --size=520 /dev/sdc make the disk availble for
Netapp again?
Has anyone tested this?


Kind regards,
Matthijs Sneijders
