Using AutoRAID Manager for Windows NT Changing Disk Array Configuration Settings To check disk array status: 1. Right-click the disk array from the Detail pane. 2. Click Properties. 3. Click the Status tab. NOTE! Double clicking on a disk array entry in the Array List window has the same effect as rightclicking the array. Changing Disk Array Configuration Settings A number of configuration settings control the operation of the disk array. These settings are usually established during installation and, once set, should rarely need to be changed. The default settings have been selected to provide the best operation for most systems. However, if you determine that any setting does not meet your needs, you can easily change it. Table 26 lists the various settings, including factors you may want to consider before changing them. Setting Active Spare Auto Rebuild Auto Include Rebuild Priority Table 26. Disk Array Configuration Settings Default On On On High Comments and Considerations Active Hot Spare provides optimum protection against disk failure. Disabling Active Hot Spare will make additional capacity available to the host, but at the expense of not maintaining data redundancy in the event of a disk failure. Auto Rebuild provides optimum protection against disk failure by rebuilding a failed disk as quickly as possible. Disabling Auto Rebuild gives you more control over the rebuild process, but it can leave the disk array vulnerable to a second disk failure until a rebuild is performed manually. Auto Include simplifies the task of adding a new disk to your array. Disabling it will require you manually to include each disk you install in the array. Rebuild priority determines how quickly a rebuild operation will complete. Windows NT 225
