Now I have couple of Supermicro 24x2Tb SATA servers and I have now idea how to get access to disks. I need to create XFS volume on each of them but really don't know how to do it, because fdisk doesn't see them.
# sg_scan -i
/dev/sg0: scsi0 channel=0 id=0 lun=0 [em]
ATA ST3250318AS CC38 [rmb=0 cmdq=0 pqual=0 pdev=0x0]
/dev/sg1: scsi1 channel=0 id=0 lun=0 [em]
ATA ST3250318AS CC38 [rmb=0 cmdq=0 pqual=0 pdev=0x0]
/dev/sg2: scsi6 channel=1 id=8 lun=0 [em]
Hitachi HDS722020ALA330 JKAO [rmb=0 cmdq=1 pqual=1 pdev=0x0]

/dev/sg25: scsi6 channel=1 id=31 lun=0 [em]

/dev/sg26: scsi6 channel=3 id=0 lun=0 [em]
LSILOGIC SASX36 A.1 7017 [rmb=0 cmdq=1 pqual=0 pdev=0xd]
# sg_map
/dev/sg0 /dev/sda
/dev/sg1 /dev/sdb
/dev/sg2
.. ... ...
/dev/sg25
/dev/sg26
I can't use fdisk and mkfs, what should I do?
