This read-only Counter reports how many times the SCSI Hardware Interface driver has detected that the SCSI bus was reset since the driver was loaded, and per the description a dramatic rise here suggests checking bus statistics for unusually high error counts, possibly pointing to a specific problem device. Admins watch this counter because occasional hard resets can be normal but a sudden increase usually signals a failing device on the bus. For example, an admin who sees this hard-reset counter jump sharply checks the per-device error counts on that bus to find the specific drive causing the resets.
