To confirm drive problem I have swapped the drve.But still I am getting error that particular drive slot (1 drive ).When i tried to use the L&TT on device analysis of that 1-slot drive giving error(Drive experiencing a high poling rate on SCSI interface.).Replaced the Libray chasis. Same error I am geeting. Please help me to sole this problem.

The drives are completely independant. The chassis supplies power to them and communicates with them via a dedicated bus but it doesn't have anything to do with the data path. If there is a problem that repeats when the drives have been switched then the problem is somewhere outside the library. Maybe software configuration.

You could post an L&TT support ticket here and there may be some tips in there.

High polling rate is often caused by driver misconfiguration. There is a utility that ships with the HP tape driver called disable autorun which will stop some of the polling.
