Configuring the Hardware and Installing Windows NT 65
16. Confirm the warning about saving configuration to a diskette by answering
Yes to quit the program. The configuration can be saved after you finished all
steps of the installation.
17. Go on to the Windows NT installation.
Note: Please remember only one logical drive should be created for the
Windows NT installation process. If any other drives are defined and you are
trying to install to a partition greater than 1 GB, this will cause problems. After
installation is complete, you can then go back or use the ServeRAID
Administration and Monitoring Utility in Windows NT and add the rest of the
logical drives that you need.
2.12.3.2 The ServeRAID II 8 MB Battery-Backup Cache
The ServeRAID II battery-backup option (part #76H5401) provides a
battery-backup cache for the ServeRAID II adapter. If power to the server or
adapter is interrupted, the data written to the ServeRAID II adapter is not lost
because a battery maintains power to the backup cache.
This gives you the possibility to improve your write performance by using the
advantages of write caching on your logical drives without the risk of data lost. An
additional powerful feature of this option allows you to change the battery-backup
to the new adapter if your ServeRAID II adapter is damaged and this new adapter
will write back the unsaved write cache data to the drives.
After installing the battery-backup cache you must set the write policy to
write-back mode for the adapter to use the battery-backup cache. This mode can
be changed without deleting or affecting your already created logical drives and
their data.
To set a logical drive to the write-back (WB) mode, do the following:
1. Start the ServeRAID configuration program from the IBM ServeRAID and
ServeRAID II configuration diskette.
2. Select 7. Advanced Functions in the in the ServeRAID adapter configuration
main menu.
3. Select 4. Logical Drives Params Management in the next menu.
4. In this menu Select 2. Change Write Policy.
5. Select the logical drive whose write policy you want to change.
With the ServeRAID adapter, ServeRAID on-board controller and ServeRAID II
adapter, synchronization is required to ensure the parity accurately reflects the
data. If synchronization or data scrubbing is performed on an array that was
never previously synchronized, then any media defect found that requires RAID
reconstruction may be rebuilt using incorrect parity which may result in data
loss.
