IOPn.Diskx Reset Mirror Copy, IOPn.Dsl Show Configuration Command

Page 121 highlights

IOPn.Diskx Reset Mirror Copy This command attempts to restart a mirror copy for a device, indicated by Diskx. This command usually is issued to restart a mirror copy that has failed because the mirror copy source disk encountered bad blocks. Typically you would enable bad block remapping immediately prior to this call. This command can also be used if you want to restart a failed mirror copy without first enabling bad block remapping. In this situation, invoking the command is a way to check whether the copy failed initially because of a transient error. If so, the mirror copy might now succeed. Command IOPn.Diskx Reset Mirror Copy Console Syntax MTCCONS IOPn.Diskx Reset Mirror Copy n - the ID number of the IOP (1 or 2) x - the ID number of the SCSI disk Results Once the mirror copy completes successfully, if bad block remapping is enabled, the system automatically turns it off, but only for the drives that just completed the mirror copy. See Also IOPn.Diskx Disable Bad Block Remap IOPn.Diskx Enable Bad Block Remap IOPn.Diskx Enable Mirrored Disk IOPn.ScsiProvider Show Mirror Status IOPn.Dsl Show Configuration Command The IOPn.Dsl Show Configuration command shows information about the DSL (Device Synchronization Layer) on the specified IOP. The DSL is the Endurance software that controls and participates in device I/O request processing on the IOPs. While the DSL operation is transparent, the DSL contains useful device information that you can display using the DSL commands. Commands 5-33
