Configuring Server A
A screen similar to the following appears:
-Important- The ServeRAID adapter only should be initialized one time
when the adapter is first installed.
Initializing the adapter removes all configuration information from NVRAM.
This information includes the SCSI IDs, the cluster and the cluster partner name, and the array information.
This point is especially important if the Windows NT system boot drive is attached to the IBM ServeRAID adapter.
If the initialization occurs after the boot drive array has been created, this array information will be removed
and the server will not be able to startup into Windows NT.
Note: Do not attempt to change the host ID on both ServeRAID adapters in a pair at the exact same time.
Doing so can cause a problem, such as a server 'lock-up.'
-Important- If your configuration will contain multiple ServeRAID adapter
pairs, each adapter Host Configuration ID must be unique.
The name of the Host ID and the Cluster Partner ID are case sensitive.
Note: Servers cannot have the same initiator_identifier IDs.
Note: Be sure to record the Host IDs and Cluster Partner IDs in a safe place for future reference.
You will need this information to recover the configuration if the ServeRAID adapter should fail.
Notes:
A ***** A0 ***** ***** ****** ****** *****
B ***** B0 ***** ***** ****** ****** *****
C ***** C0 ***** ***** ****** ****** *****
If logical drives are created out of order, meaning you do not follow the order mentioned above, then they are listed on the
screen out of order, which might cause some confusion.
For example, say you created two arrays, A and B, but did not define any logical drives at that time.
Then, afterwards, you go back and create a logical drive on array B.
That logical drive will then appear in the first line of the logical drive box.
Now, if you go back and create another logical drive on array A, that logical drive will show up on the second line of the
logical drive box, as shown in the second figure.
A ***** B0 ***** ***** ****** ****** *****
B ***** A0 ***** ***** ****** ****** *****
Notes:
p.
1) You must have two or more drives for RAID level 1 and three or more drives
for RAID level 5 within the same array.
2) In the Windows NT environment, you must create at least one logical drive,
the quorum drive, as RAID level-1 to store the quorum resource information.
This drive can be used to store customer programs and data.
or
Drag the drive or SCSI Channel icon from the Main Tree and drop it on the Array or Hot-Spare
Drive icon in the Main Panel on the right.
If you change your mind, you can drag the icons back to the Main Tree to remove them from the
configuration.
If you change your mind, you can:
Notes:
1) Some operating systems have size limitations for logical drives.
Before you save the configuration, you might want to verify that the size
of the logical drive is appropriate for your operating system.
See your operating-system documentation for more detailed information.
2) Typically, the first logical drive defined on the first ServeRAID adapter
found by system BIOS during startup will be your startup (boot) drive.
Note: To change the configuration, click on Modify icon button.
Note: For Microsoft Windows NT clusters, you should define all shared logical drives on server A.
Then, continue with step 12.
To set the Merge IDs, do the following: :
