Hello Razi,

lbolt and SCSI resets occur once in a while. This happened to me whenever there is a temperature problem in the data center.

do a pvdisplay and look at the status.
also ioscan | grep -iv CLAIMED

Hi Razi,

It sounds like the device at *c8t3d0* has encountered a scsi reset.

I suspect the device is DLT dive, If this is the case then reason could be the external drive might got power recycle or else the skis terminator gone bad.
