4.14 Defining EnclosuresThere are two different cases with customized enclosures: Case 1 is an enclosure window pre-defined by system vendors. The enclosure may be presented as a front view drawing or photograph. The user may have to add devices into the pre-defined spaces. Case 2 is an enclosure window showing only spaces representing device canisters. In case 2, you must start from the beginning to arrange devices in an enclosure.
Both cases allow you to replicate real enclosures with real drive bays, depicting the exact locations and positions of the physical drives and RAID controller(s). In both cases, you create custom enclosures to facilitate management of the physical drives in the disk array system. These enclosures can closely replicate real enclosures with real drive bays, depicting the exact locations and positions of the physical drives. When a drive fails, determining which drive to replace is simply a matter of checking the Enclosure window for the exact location of the failed drive (a failed drive appears with a red X mark on its icon).
Creating an enclosure
1. Display the Enclosure window. To display it, click on the Enclosure command button (Case 1) or select the Enclosure command from the Open menu (Case 2).
2. The Enclosure window has pre-configured spaces that resemble the controller and drive canisters of your enclosure. The enclosure window may have been defined by your system vendor.
3. Click on an empty space that represents an empty canister or drive bay within the Enclosure window (horizontal or vertical). The space you selected will be highlighted by a different color. Next click on a drive icon from the navigation panel, then click the Add button. If an empty space does not match the drive icon or controller icon you selected, the Add button will be unavailable. This happens when you try to place a drive in an inadequate canister (e.g., you cannot place a drive in a controller canister; and you should arrange your drives according to their actual locations and SCSI ID sequence). Repeat to add more drives. Using this same method, monitoring device icons can also be added to defined enclosures.
4. Drives may only be added to one enclosure and the enclosure window provides no “auto-update” function. If drives are added or removed from your array, you will need to manually update the enclosure settings in the Enclosure window.
5. The Enclosure window also supports a logical view of connected drives. Click on the Logical button to display the logical relationship among physical drives. Physical drives configured in a logical drive group will be displayed in the same color. If there is more than one logical drive, different colors will be displayed to distinguish members of different logical drives.
6. Physical View under the RAID View window also provides a real-time report on drive status, using the same symbols and colors to represent various conditions. What you see in the Enclosure window is also reflected in the Physical View. These windows, however, differ in the way physical drives are presented; in the Enclosure window, the drives should be arranged according to their actual locations in the drive bays, while in Physical View the drives are arranged according to channel connections.
Removing a drive from an enclosure1. While in Edit mode, click on the target drive.
2. Click the Remove button.
