What i must to do for successfully recognize all attached disk by controller?

So a few things here,

     If this is a production system open a support case. If this is not production Next make sure the version of DOT is compatible with that hardware. Reseat all components can verify the state of the problem does not change.  Next Ensure the module firmware is up to date and the disk qual file is current. Swapping the A to B modules can provide insight if the issue is with the module or something else. 

Hope this helps

Thanks for reply olson. i figure out it with changing IOM speed to 2 Gbit. there are X275  model disk type and X275 disks not supporting 4gbit speed.

thanks.
