How to maintain or verify a disk array The Maintain Disk Array (see Figure 12) shows the current disk array configuration that you have selected. The array's Write Cache State can be changed. Refer to Select write cache properties paragraph in the Creating a disk array section. Verify Array can be specified as no or yes. The default is no. Yes launches a foreground process that checks the data integrity of a fault tolerant 36 www.3ware.com 3ware Disk Array Configuration Utility array. If the verify array process determines that the mirrored drives are not identical or the parity is not correct, the array is degraded and the rebuild process is launched. Maintain Disk Array The array listed below can have its write cache state changed. Verify checks the data integrity of a fault tolerant array.

For RAID 1 and 10 arrays the initial verify must first be done in 3DM, otherwise the initialization will not be done. Rebuilding a mirrored disk array Escalade ATA RAID Controllers allow you to create fault tolerant disk arrays by selecting a mirrored RAID 1 or RAID 10 array. These disk arrays store identical data on two or more drives to protect against drive failure. If one or more of the drives of a mirrored www.3ware.com 37
