Usage Guidelines A WAAS device can use two disk drives to increase storage capacity or to increase reliability. This is
known as Redundant Array of Independent Disks (RAID) and is implemented in WAAS as a software
feature.
RAID-1 is automatically applied to any WAAS device that is running the WAAS software and that have
two or more disk drives. RAID-1 provides disk mirroring (data is written redundantly to two or more
drives). The goal is higher reliability through redundancy. With RAID-1, file system write performance
may be affected because each disk write must be executed against two disk drives.
delete-partitions Deletes data on the specified disk drive. After using this command, the
WAAS software treats the specified disk drive as blank. All previous data
on the drive is inaccessible.
diskname Name of the disk from which to delete partitions (disk00, disk01).
mark Marks a disk drive as good or bad.
diskname Name of the disk to be marked (disk00, disk01).
bad Marks the specified disk drive as bad. Using this command makes data on
this disk inaccessible. If later this disk is marked good, WAAS software
treats it as a blank drive.
good Marks the specified disk drive as good.
reformat Performs a low-level reformatting of a SCSI disk drive and remaps bad
sectors.
Caution Use this command with extreme caution to avoid loss of data.
diskname Name of the disk to be reformatted (disk00, disk01).
scan-errors Scans SCSI or IDE disks for errors and remaps the bad sectors, if they are
unused.
diskname Name of the disk to be scanned for errors (disk00, disk01).
