8.0 Copying Drives

Copying drives using the DriveCopy CLI command may be necessary on drives in the JBOD configuration.

DriveCopy can create a backup of a drive onto another drive sled. If one drive fails, DriveCopy may be used to copy the data off the remaining drive on the sled to another drive on another sled. Once completed, the sled containing the failed drive may be replaced.

CAUTION

Make sure the destination backup drive sled does not contain any important data because it will be completely overwritten by the DriveCopy command.

Procedure

Use the DriveCopy CLI command (refer to Drive Configuration Commands on page 45) or use the Advanced CLI Configuration page in the ExpressNAV interface to copy a drive from the source disk to the destination disk. Parameters are the sled and drive numbers of the source and destination drives.

The destination drive must be offline: use the ATADiskState command to determine if the destination disk is offline. If you choose the same

source and destination drive, this command will perform a DriveWipe.

DriveCopyHalt stops a DriveCopy operation in progress. DriveCopyResume resumes a DriveCopy

operation that had been stopped. DriveCopyStatus displays the status of a DriveCopy or DriveWipe operation

CAUTION

JBOD configurations

You may want to copy drives for backup. However, since several configurations may be present on a Diamond Storage Array, you must be confident you are accessing and overwriting the appropriate drives and volumes.

CAUTION

RAID Level 0 systems

DriveCopy may be used to coordinate the generation of a backup of an entire RAID Level 0 LUN.
