Configuring ServeRAID arrays and logical drives
To configure arrays and a logical drive, do the following.
Note: You can create only one logical drive for each array in a failover
environment.
1.
Click (
Create arrays
) on the tool bar. The Configuration mode window
opens (see Figure 16 on page 45).
2. In the Main Tree, click the first ServeRAID controller that you want to
configure.
3. Click the Custom configuration button.
4. Click Next. The Create arrays window opens.
5. Using the right mouse button, click the ready drive or SCSI channel icons in
the Main Tree to select the drives that you want to add to your arrays or delete
from your arrays; then, select a choice from the pop-up list.
Notes:
a. You must use all the ready drives when creating your arrays (that is, all
ready drives in the Main Tree must be online).
b. Hot-spare drives are not supported in a failover environment except the
built-in hot-spare that is part of a RAID level-5E logical drive.
6. After you select the ready drives for your arrays, click Next. The Create logical
drives window opens.
Note: If you change your mind, you can remove a specific drive from a newly
defined array or delete an entire newly defined array. To do this:
a. Click Back.
b. Using the right mouse button, click the specific drive or Array icon in
the Main Panel on the right.
c. Click Remove from new array or Delete new array.
7. Select a RAID level for each of the logical drives from the RAID pull-down
menu in the Main Panel.
8. Create only one logical drive for each array.
Note: Typically, the first logical drive defined on the first ServeRAID controller
found by system BIOS during startup will be your startup (boot) drive.
9. If you have created multiple arrays in step 5 on page 48, click another array in
the Main Tree and go back to step 7 on page 48 to configure it. After
configuring all of your arrays, go to step 10 on page 48.
10. Click Next. The Configuration summary window opens.
11. Review the information that displays on the Configuration summary window.
Click Apply to accept and save the configuration.
Note: To change the configuration, click Modify arrays or Modify logical
drives.
12. Click Yes to continue working with your ServeRAID configuration. After
creating the arrays and logical drives, you must assign merge group numbers
to the shared logical drives.
