tiez, som si myslel, ze je to tak... ale pravda je taka,
ze bez ovladacov to funguje len ako radic (vidis kazdy disk samostatne)
takto: (HPT366)
Jun 28 12:02:08 storage kernel: hde: 150136560 sectors (76870 MB) w/1916KiB Cache, CHS=148945/16/63, UDMA(44)
Jun 28 12:02:08 storage kernel: hdg: 150136560 sectors (76870 MB) w/1916KiB Cache, CHS=148945/16/63, UDMA(44)

ale napriklad taka AMI Megaraid, robi takyto wh raid:
Jun 28 12:02:08 storage kernel: megaraid: v1.15d (Release Date: Wed May 30 17:30:41 EDT 2001)
Jun 28 12:02:08 storage kernel: megaraid: found 0x101e:0x1960:idx 0:bus 3:slot 0:func 0

Jun 28 12:02:08 storage kernel: scsi0: scanning virtual channel for logical drives.
