Problems with SAS disk's

I have platform SR26126URR,motherboard SR5520UR,RAID controller RS25DB080, backplane SR2612UR, midplane TCA-00277-01-C and 6 hard disk's SAS Seagate Chetah 15K.6 ST3450856SS(fw:0006). It's worked.

I added 6 SAS disk Seagate Enterprise Perfomance 10K HDD v8 ST600MM0208 (fw:n001).

In RAID console new disk's Seagate is not initialized.

After connecting, power on HDD is not available.

Can you help me?

New controller supported new disk Seagate Enterprise Perfomance 10K HDD v8 ST600MM0208?
