I have a one problem with Raid controller Tekram TR-822... I'm using dmraid software: root@ns1: / $ dmraid -r /dev/sda: sil, "sil_ajacddafagff", mirror, ok, 156299440 sectors, data@ 0 /dev/sdb: sil, "sil_ajacddafagff", mirror, ok, 156299440 sectors, data@ 0
When I'm start dmraid -ay: root@ns1: / $ dmraid -ay RAID set "sil_ajacddafagff" was not activated
And I see from dmesg: device-mapper: table: 253:0: mirror: Device lookup failure device-mapper: ioctl: error adding target to table
My system centos My kernel 2.6.18-128.1.10.el5.centos.plus

Remove the RAID configuration from the card's "BIOS" and just run them as standard SATA volumes. Then, use software raid to accomplish your mirror. The 'fake-raid' junk will likely keep giving you headaches. Or, get a controller that has *REAL* hardware RAID like a 3ware or Areca.
