Anleitung Zusammenfassung
You can create a maximum of eight arrays from the BIOS. See “Understanding Arrays” if you have not yet decided what type of arrays you need. DNS-3200 User’s Manual 54 Notes: 1. In some circumstances, more than eight arrays are possible and may appear to function properly, but are not supported by Broadcom. 2. For redundant arrays, the creation process does not complete until after the operating system and controller drivers have been installed and you have booted into the operating system context. However, the arrays are immediately available to use for either a boot or data array. 3. Array numbers are valid only for a given boot, and may be different in the BIOS and drivers. If a permanent label is required, use the labeling feature. 4. When you highlight a disk from the Disk list, the LEDs on the controller or a properly cabled disk enclosure light up to identify that disk. 5. At any point in the following procedure, you can return to a prior screen by pressing ESC. 6. See see “Color Codes for the BIOS Array Con- fig Utility” in 5.2. To create an array: 1. From the main menu of the Array Configuration screen, select Create Array using the arrow keys, and then press Enter. 2. Select the disks on which to create the array by doing the following: a. Highlight the disk using the arrow keys. b. For each disk, press the Insert key to select the disk. You can insert the disks in any order. c. After selecting the disks to be included in the array, press Enter. 3. In the User Input area, select an array type with the arrow keys, and then press Enter. Only array types that can be created with the selected disks are available. 4. If spares are applicable: 55 Chapter 5 a. In the User Input area, highlight a spare type using the arrow keys. b. If applicable, in the Disks area, highlight the disk(s) to use as a spare and press Insert to select them. c. Press Enter to add the spare disk(s). 5. To select an array size, do one of the following: 6. Use the Page Up/Page Down keys or the arrow keys to select a size, and then press Enter. Note: By default all available space up to 2.199 TB is selected. Or do the following: To create an array that is greater than 2.199 TB (the maximum allowed by some operating systems): Note: The Windows operating system does not support arrays larger than 2 TB. 1. Press PAGE UP or the up arrow to increase the array size. You are asked if you want to limit the size of the array to the 2 TB maximum. 2. Press ESC to create a larger array. 3. Press PAGE UP or the up arrow until you have reached either the desired size or the maximum available. 4. Press Enter. 5. Select a caching mode using the arrow keys, and then press Enter. 6. Press C to continue the array creation process. DNS-3200 User’s Manual 56 Note: For installations of SuSE Linux, a popup appears that says, “A new device was found, do you want to configure it?” If you do not want to see this popup when you create arrays, you can check the “Do not notify me” checkbox. 7. The array is marked Ready for use, and the text at the top of Array Configuration returns to a description of the menu items. 8. When you are finished creating arrays, resume the boot process: a. From the Main menu, highlight Continue to Boot. b. Press Enter. No reboot is required. Figure 5.1: Create an array In the example above, a 4-drive RAID5 array has been configured. 57 Chapter 5 5.5 Deleting Arrays from the BIOS This option allows you to delete arrays. Caution!: Deleting an array permanently destroys all data that was on the array. You will not be able to undo this action and all data will be lost. To Delete an Array: 1. Highlight Delete Array(s) from the Main menu and press Enter. 2. Do one of the following: a. Highlight each array to delete and press Insert to select it. Or b. Type A to select all arrays for deletion. 3. Press Enter. 4. Press C to continue. 5.6 Swapping Arrays from the BIOS Using the Swap Two Arrays option, you can reorder arrays. Notes: 1. If you create more than one array, you can install the operating system to any of them. However, a small amount of boot information is always written to a disk in the first array on your array list regardless of which array you install the operating system on. If anything happens to that disk in Array 1, you will not be able to boot. Broadcom recommends installing on a redundant array type — such as RAID1 or RAID5 — and then swapping that array into the first position if it is not already Array 1. 2. This swap feature is only available from the BIOS. DNS-3200 User’s Manual 58 To swap arrays: 1. Highlight Swap Two Arrays in the Main menu, and then press Enter. 2. Use the arrow keys to highlight an array, and then press Insert to select it. 3. Use the arrow keys to highlight another array, and then press Insert to select it. 4. Press Enter to swap the arrays. Figure 5.2: Swap arrays In this example, the RAID10 array was the first array created. However, to boot from the RAID5 array, the arrays were swapped so t...
