Replacing a RAID 1 drive
If configured as RAID 1, you will repair the system by replacing the drive as soon as possible. You
can replace a single RAID 1 drive while continuing media operations.
Always use the Storage Utility to physically identify the failed drive. Accidentally removing the
wrong drive can destroy data. To identify a drive, in Storage Utility right-click the drive and select
Identify . This causes the disk lights to flash. Refer to related topics in "K2 System Guide" for Storage
Utility procedures.
NOTE: Do not shut down. Keep the system powered on while replacing a drive.
Before removing the disk module, you should use Storage Utility to disable the disk.
To remove and insert a drive, refer to the mechanical procedure for disk module removal.
On inserting a RAID 1 replacement drive, if disk access (record/play operations) is underway, the
RAID controller automatically starts rebuilding the drive. You can verify rebuild status by looking
at the drive LED or by looking at the Service LED. If there is no media access currently underway,
you can use Storage Utility to force-start the rebuild process.
You can also check disk status in the Storage Utility by selecting the disk module icon in the device
tree. Status is reported in the right-hand pane. On completion, the disk drive status changes from
Rebuilding to Online. You may need to refresh the Storage Utility display. You can also open the
Progress dialog box, by clicking
View | Progress Report .
