Info

Regenerating Logical Drive Parity If no verifying method is applied to data writes, this function can be performed every so often by user to ensure bad sectors will not cause data loss in the event of drive failure. In a <strong>RAID</strong> unit, data is striped across multiple member drives and this function can regenerate parity and prevent bad blocks on drives. Choose the logical drive that you want to regenerate the parity for, and then press [ENTER]. Choose “Regenerate Parity,” then press [ENTER]. When prompted to “Regenerate Parity?,” select Yes. IMPORTANT! • If a regenerating process is stopped by a drive failure, the process cannot restart until logical drive rebuild has been completed. Terminal Operation 8-17
8-18 8.10 Viewing and Editing Host LUNs Viewing or Deleting LUN Mappings Choose the host channel and SCSI ID of the LUN mapping you wish to view or delete. A list of the current LUN mapping will be displayed on the screen. Move the cursor bar to the LUN mapping you wish to delete, then press [ENTER]. Select Yes to delete the LUN mapping, or No to cancel. Pass-through SCSI Commands If you have primary and secondary controllers, move the cursor to the controller for the device that you wish to map; then press [ENTER]. You will be prompted to map a SCSI ID to a physical drive. WARNING! • Pass-through SCSI Commands are only intended to perform maintenance functions for a drive or device on the drive side. Do not perform any destructive commands to a disk drive (i.e., any commands that write data to a drive media). This will result in inconsistent parity among drives included in a logical configuration of drives. If a disk drive is a spare drive or a member of a logical drive, such a destructive command may cause a data inconsistency. • When a drive/device is mapped to a host SCSI ID so that Pass-through SCSI Commands can be used, the data on that drive/device will not be protected by the controller. Users who employ Pass-through SCSI Commands to perform any write commands to drive media do so at their own risk. <strong>Infortrend</strong>
