Increasing Free Space - IBM Netfinity ServeRAID-3H Installation And User Manual

Note: Change RAID levels is a lengthy process. You cannot perform any other actions on the
affected controller until the migration is complete. The ServeRAID Manager program displays
a progress indicator in the status bar. You can use the logical drive during the change RAID
levels process. You can also remove the system power. When you restore the power, the
change RAID levels process restarts where it left off.
8. Click Yes when the confirm pop-up window opens.

Increasing free space

Using this feature you can add one, two, or three physical drives to an existing array so you can create
another logical drive in the array.
When you create an array, logical drives are striped across all physical drives in that array. To create
more free space in an existing array, define additional physical drives to add to the array. Then, the
ServeRAID Manager program migrates the logical drives such that the data is spread across the existing
and new physical drives.
To increase free space:
1. Click an array from the Main Tree (that is, the left tree).
2. Select Logical drive migration from the Actions menu.
3. Select Increase free space from the menu.
4. Add to the selected array by dragging ready drives from the Main Tree to the array in the right tree.
Note: You can add up to three physical drives.
5. After you add the physical drives to your arrays, click Next to review your new logical drive
configuration.
6. Review the configuration in the right panel. It describes how the configuration will affect the logical
drives and free space when you click Apply. If you want to modify the configuration, click Back to
return to the array tree window.
Tip: You can expand the tree for another view of the configuration.
7. Click Apply to approve the new configuration. The ServeRAID Manager program automatically
increases the free space.
If you do not want to approve the logical drive configuration, click Cancel and return to the system
management information window.
8. Click Yes when the confirm pop-up window opens.
Note: Increasing free space is a lengthy process. You cannot perform any other actions on the

indicator in the status bar. You can use the logical drive during the increase free space
process. You can also remove the system power. When you restore the power, the increase
free space process restarts where it left off.
9. When the increase free space process completes, you can create new logical drives in this array. See
"Using Custom configuration" on page 25 to review this process.
