MegaRAID Storage Manager Online Help System |
Creating a New Configuration
You use the MegaRAID Storage Manager Configuration wizard to create new striped and mirrored disk arrays/virtual disks. You can create one or two virtual disks on each controller.
To open the Configuration wizard, select a controller icon in the left panel and then select Operations >> Configuration >> Configuration Wizard.
Follow these steps to create a new array/virtual disk with the Configuration wizard:
- Select one or more physical drives for the new array in the left panel and click the right arrow to move them to the right panel.
Use Shift-click to select multiple drives. If you change your mind, select a physical drive in the right panel and click the left arrow to move it back to the left panel.- Click Accept to accept these physical drives for the new array.
- Click Next to continue.
- On the next screen, select a RAID level.
If you selected two drives, the options are RAID 0 (striped) and RAID 1 (mirrored). If you selected three or more drives, the options are RAID 0 and RAID 1E. (For information about RAID levels, see Understanding RAID Levels.)- [Optional] Change the disk cache policy, if desired. The options are Unchanged (that is, unchanged from whatever the current cache policy is), Enabled, and Disabled.
A warning appears if you try to enable disk caching for a mirrored (RAID 1 or RAID 1E) array.
You should not enable disk caching on a mirrored array. If you do, data may be corrupted or lost in the event of a sudden power loss.
- Click Accept.
- If this is a RAID 1 array, select a primary disk and click OK.
When a RAID 1 array is created, existing data from the primary disk is mirrored (copied) to the other, secondary disk. If the two disks are the same size, you can select either one as the primary disk. If they are different sizes, you can only select the smaller of the two as the primary disk.- Click Next. The Finish screen appears.
- Review the new virtual disk configuration. If you need to change something, click Back to return to the earlier screens.
- Click Finish to create the virtual disk. The main screen reappears when this process is completed.
