Configuring arrays and logical drives for failover
Connecting

the arrays and logical drives | Completing
the installation
Notes:
-
- You must configure arrays and logical drives only on the active
controller.
- You can create only one logical drive for each array in a failover environment.
To configure arrays and logical drives, do the following:
- On the toolbar, click
(Configure RAID). The Configuration wizard opens.
- In the tree, click the ServeRAID controller that you want to configure as
the active controller.
- Click Custom configuration.
- Click Next. The "Create arrays" window opens.
- Click the appropriate Array tab in the right pane;
then, from the ready drives list, select the drives that you want to move
to the array.
- Click
>>
(Add selected drives) to add the drives to an array. You can click
>>
(Add all drives) to move all ready drives to an array.
- Repeat steps 5 to 6 for each additional array that you want to configure.
Notes:
-
- You must use all the ready drives when creating your arrays (that
is, all ready drives in the tree must be online).
- Hot-spare drives are not supported in a failover environment. The
exception is the built-in hot-spare that is part of a RAID level-5E
logical drive.
- After you select the ready drives for your arrays, click Next. The
"Create logical drives" window opens.
- Click the appropriate Array tab.
- Select a RAID level from the drop-down list.
Notes:
-
- Create only one logical drive for each array.
- Typically, the first logical drive defined on the first ServeRAID
controller found by system BIOS during startup will be your startup
(boot) drive.
- Repeat steps 9 and 10 for each additional array you want to configure.
- Click Next. The "Configuration summary" window opens.
- Review the information that is displayed in the "Configuration summary"
window. To change the configuration, click Back.
- Click Apply; then, click Yes when asked if you want to apply
the new configuration. The configuration is saved in the ServeRAID controller
and on the physical drives.
- Click Continue to return to ServeRAID Manager. After creating the
arrays and logical drives, you must assign merge-group numbers to the shared
logical drives.
- In the tree, click the active controller (that is, the ServeRAID controller
that contains the logical drives).
- Click
(Configure
for clustering) on the toolbar. The "Configure controller for clustering"
window opens.

- Select the Shared check boxes for all the logical drives.
- Do not change the merge-group number from the default provided.
- Record the controller name, partner name, and merge-group numbers; store
them in a safe place. You will need this information to recover the configuration
if the ServeRAID controller fails.
Note: You can
save this information to a file by using the ServeRAID Manager:
- In the tree, right-click the server.
- Click Save printable configuration.
- Click OK.
