Breaking a RAID-1 array (mirror) If you want to permanently stop using the secondary hard disk drive for mirroring, you must break the RAID-1 array (mirror). When you break the RAID-1 array, all data is permanently erased from the secondary internal hard disk. To break the RAID-1 array: 1 Click Start, All Programs. Then, select TOSHIBA, RAID, RAID Console. The TOSHIBA RAID Console is displayed. 2 Click Disable RAID. The Confirm disk mirroring window appears. Sample Confirm disk mirroring window 3 Click OK. The mirror between the primary internal hard disk and secondary internal hard disk is broken and the information on the secondary internal hard disk is permanently erased. Using the RAID-0 or RAID-1 Utility 278 Rebuilding the data on the secondary disk in a RAID-1 array Rebuilding the data on the secondary disk in a RAID-1 array If the secondary hard disk has been removed from the computer and you want to resume using the secondary hard disk for mirroring, you must reinsert the secondary hard disk drive into the computer. If Auto Rebuild has previously been enabled on the Options window of the TOSHIBA RAID Console, rebuilding will start when the secondary hard disk drive is reinserted into the computer. If Auto Rebuild has not previously been enabled: 1 Insert the secondary hard disk drive into the computer. 2 Plug in the AC adapter and power on the computer. (The computer must be running on power provided by the AC adapter to perform these steps.) When rebuilding the RAID-1 array, all existing data on the secondary hard disk will be permanently erased and cannot be recovered. Toshiba is not responsible for any loss of data on the hard disk. NOTE If a hard disk password has previously been assigned, the password entry window will display. You must enter the hard disk password to continue. 3 The message “Mirror is broken” displays. Click OK. 4 Start up the TOSHIBA RAID Console Utility by clicking Start, All Programs. Then select TOSHIBA, RAID, RAID Console. 5 Click Mirroring. Using the RAID-0 or RAID-1 Utility 279 Rebuilding the data on the secondary disk in a RAID-1 array The Confirm disk mirroring window appears. Sample Confirm disk mirroring window 6 Click OK. 7 The Confirm disk mirroring window appears. Sample Confirm disk mirroring window 8 Click OK. The computer begins copying data from the internal hard disk to the secondary hard disk drive. It may take several minutes or up to one hour to rebuild the array depending on the amount of data to be copied. The progress of the rebuilding process can be viewed on the TOSHIBA RAID Console window. Using the RAID-0 or RAID-1 Utility 280 Restoring a failed drive in a RAID-1 array Restoring a failed drive in a RAID-1 array If your computer’s primary hard disk fails the failed hard disk can be removed and replaced with the secondary hard disk that contains the mirrored data. Contact Toshiba Global Support Centre or a Toshiba Authorized Service Provider for assistance. Removing the failed primary hard disk and replacing it with the seconary hard disk improperly could damage your computer or result in the loss of data. NOTE If you want to resume mirroring, you must purchase a new secondary hard disk and recreate the array. For information on recreating the array, see “When you first start your computer” on page 260. To restore a failed internal hard disk: 1 Remove the failed internal hard disk from the computer. 2 Replace the failed primary hard disk with the secondary hard disk (that contains the mirrored data). 3 Install a new secondary hard disk. 4 Plug in the AC adapter and power on the computer. (The computer must be running from power provided by the AC adapter to perform these steps.) 5 Restart the computer. 6 The New HDD detected window appears. 7 Click OK. 8 Click Enable RAID to copy data from the internal hard disk to the secondary hard disk. Using the RAID-0 or RAID-1 Utility 281 Error message examples Error message examples The following error messages may be displayed on the TOSHIBA RAID Console. Not enough memory available. Increase the available memory by shutting down one or more applications. Another user is working in administrator mode. Currently unable to use it. Another user is logged onto the computer as an administrator and using the TOSHIBA RAID Console utility. Only one administrator can use the TOSHIBA RAID Console utility on your computer at one time. The number of connectable units has been exceeded. Currently it will not connect to the RAID service as another user is using it. Only one instance of the TOSHIBA RAID Console utility can be opened on your computer at one time. Unable to setup RAID, as the disk is in use. Shut down the application currently in use and then set up RAID. A failure has occurred in the array. Please press the button to stop the beep. The configured mirroring on the disk appears to be abnormal. Check the status of the array by starting the RAID Console. It is necessary to replace the physical drive if the physi...
