Package: udev
Version: 215-8
Hello,
I've replaced a failed SAS disk on my machine DELL Precision T7500 but udev
won't create block device, sg device is in place.
I'm using Debian Jessie XEN kernel:

Here is the CUT from dmesg, you will be able to see sdd device is created
for the SAS drive installed during installation but there is no sd device
created for the newly attached disk:
