Bad Drive or Bad Cable?

Recommended Posts

When a drive loses connection with the controller, the drive will drop from the array and also be unavailable for smart reports. Rebooting will usually restore connectivity and allow you to get the smart report.

 

Vast majority of the time these things are cable related, especially if you've recently had occasion to open the server and rattle the cables. The smart report will be useful to see if there are any significant disk issues.

SMART looks fine, but there are signs of a bad SATA cable.

Replace it and rebuild to the same disk.

 

Can't seem to locate the steps for rebuilding to the same disk...
