set (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNamen] | virtualDisk ) mediaScanEnabled=(TRUE | FALSE) The set storageArray command defines how frequently a media scan is run on a storage array. The following syntax is the general form of the command: set storageArray mediaScanRate=(disabled | 1-30) Running a Consistency Check Consistency checks are performed when media scans are run, if consistency check is enabled on the virtual disk. (See "Running a Media Scan" on page 91 for an explanation about setting up and running media scans.) During a consistency check, all data blocks in a virtual disk are scanned, and deteriorated data is corrected. The method of correction depends on the redundant array of independent disks (RAID) levels: • RAID 5 and RAID 6 virtual disks - Consistency is checked and repaired. • RAID 1 virtual disks - The data is compared between the mirrored physical disks, and data inconsistencies are repaired. • RAID 0 virtual disks - No redundancy exists. Before attempting a consistency check, you must enable the process with the set virtualDisk command, which uses the following general form: set (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNamen] | virtualDisk ) consistencyCheckEnabled=(TRUE | FALSE) Maintaining a Storage Array 93
