11. In the Main Tree, click the ServeRAID controller that contains the logical
drives.
Notes:
a. Valid merge group numbers for non-shared logical drives are 206 and 207.
For example, set all non-shared drives on Server A to merge group number
206 and all non-shared drives on Server B to merge group number 207.
b. The merge group number must be unique for each logical drive that is
shared by the controller pair. For example, if you have a logical drive with a
merge group number 1 on Server A, you cannot assign the same group
number to a logical drive on Server B. Valid merge group numbers for
shared logical drives are in the range 1-8.
12. Click on the tool bar. The Configure for clustering window opens.
13. Click the Shared check boxes for all the logical drives.
14. Do not change the merge group number from the default that is provided.
15. Record the controller name, partner name, and merge group numbers and
store them in a safe place. You will need this information to recover the
configuration if the ServeRAID controller should fail.
Note: You can save this information to a file by using the ServeRAID Manager
program:
a. In the Main Tree, click the server.
b. Click Actions
