When a disk starts to die slowly multipath starts to Failing & Reinstating paths and this keeps forever.. (I'm using LSI-3008HBA card with SAS-JBOD not FC-Network)
Dmesg;

Sep 13 11:20:18 DEV2 kernel: device-mapper: multipath: Failing path 130:240.
Sep 13 11:25:34 DEV2 kernel: device-mapper: multipath: Reinstating path 130:240.
As you can see kernel aborted the mission and after that multipath failed.
So I want to get rid of this problem via telling Multipath "do not Reinstate the path".
This method will keep dead the zombie disk.
How can I do that?
