b. For Windows NT and Windows 2000 clusters, define all shared logical
drives on Server A.
10. 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.
Note: A merge group number uniquely identifies each logical drive, even when
the logical drive moves between servers.
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 (
Configure for clustering
) 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 fails.
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
→
Save printable configuration.
