The consistency check is executed. Select [Group Operations] → [Show Progress] on the menu bar to see the progress of the execution.
Operation 45 3.4.2 Canceling Check Consistency The check consistency can be cancelled in the following procedure. Check consistency canceling procedure 1. Select [Group Operations] → [Show Progress] on the menu bar. 2. The Group Show Progress screen appears. Click [Abort] to the right of the progress indication. [Abort All]: With more than one logical drive being subject to the check consistency, allows the check consistency to be canceled for all the logical drives...
46 Operation 3.5 Patrol Read Feature The Patrol Read feature operates in physical drives configuring all arrays including hot-spare disks to detect errors and recover the system from the errors if they are detected. IMPORTANT: The Check Consistency function and the Patrol Read function allow you to find the defects (due to degradation such as aging) in files of low access frequency and unused areas as soon as possible.
Operation 47 To interrupt the Patrol Read being executed, click [Operations] → [Stop Patrol Read].
48 Operation 3.5.2 Scheduling Patrol Read The Patrol Read can be scheduled in the following procedure. Patrol Read scheduling procedure 1. Select a controller on the Physical/Logical View.

If [Auto] is selected already, the mode change is not required.
Operation 49 [Execution Frequency]: Specify the interval at which the Patrol Read is executed. You can set the interval in hours, minutes, or seconds. NOTES: If you shutdown the server on the way of manual Patrol Read, it is aborted. Execute the Patrol Read again when the server is started.
50 Operation 3.6 Rebuild Feature The rebuild feature can recovers a degraded array. Before the feature can be used, the defected hard disk drive must be replaced with a normal hard disk drive. The rebuild can be done in the following three ways. [Hot-swap rebuild]: This method provides rebuild by replacing a hard disk drive defected during system operation with a normal hard disk drive.
Operation 51 3.6.1 Hot-swap Rebuild The feature can be done in the following procedure: 1. Find the defected hard disk drive. The following figure shows a sample display in MSM. The icon shows a degraded logical drive. The icon shows a defected hard disk drive.
52 Operation 3.6.2 Hot-spare Rebuild 220.127.116.11 Hot-spare Disk Setting Procedure Global hot-spare setting procedure 1. Specify an unused hard disk drive shown on the Physical view and right-click it. 2. Select [Make Global Hotspare] in the menu displayed by right-clicking. 3.
Operation 53 3.7 Reconstruction Feature The reconstruction feature allows you to increase in the capacity of an existing array and/or change its RAID level. IMPORTANT: Execution of reconstruction It is recommended that the partitions on a logical drive are always backed up before the addition of the capacity of the array so that proper measures can be taken at the occurrence of an unexpected event.
54 Operation The reconstruction is divided into three types; Add Drive, Remove Drive and Change RAID Level. [Add Drive]: Add a physical drive to the logical drive to increase in the capacity of the array. [Remove Drive]: Removes the physical drive from the logical drive and converts the RAID level to RAID 0.
Operation 55 2. Select the physical drive to be added from the upper list and click the button to move the physical drive to the lower list. Then click [Next]. 3. The physical drive to be added appears with red characters. Select the RAID level after the expansion from [New RAID Level] and click [Finish].
56 Operation 18.104.22.168 Remove Drive This feature removes the physical drive from the logical drive and converts the RAID level to RAID 0. The procedure is described below. 1. Click [Remove Drive] in Reconstruction Mode of the Reconstruction Wizard. 2. Select the physical drive to be removed from the upper list and click the button to move the physical drive to the lower list.
Operation 57 22.214.171.124 Change RAID Level This feature converts the RAID level to RAID 0. The procedure is described below. 1. Click [Change RAID Level] in Reconstruction Mode of the Reconstruction Wizard. 2. Select RAID 0 from New RAID Level and click [Finish]. 3.
