You cannot install Windows NT Server if a system is configured with three or more
RAID controllers on which the RAID disk arrays have been initialized. If you must re-
install Windows NT Server, remove all but the primary RAID controller (the controller
where the operating system will reside) and install Windows NT Server. Then, replace
the remaining controllers and continue with system configuration.
u
Installation of Windows NT Server may fail if you configured the RAID disk arrays on a
system to contain more than one initialized system drive. If this happens, try the
installation again. During the second installation, make sure to reformat the system
drive (do not select Setup’s “Leave file system intact” option).
If you encounter any other problems using multiple RAID disk arrays on an Intergraph
system running Windows NT Server, contact the Customer Response Center at
1-800-633-7248 for help.
Formatting RAID Disk Drives
Because of anomalies associated with formatting RAID disk drives when using MegaRAID
Power Console, Intergraph Computer Systems recommends that you use MegaRAID BIOS
Setup to format RAID disk drives in your InterRAID-8e disk array.
CAUTION
These anomalies, while intermittent, can exhibit severe symptoms, including temporary
system lockups and a permanent hang of Power Console.
Creating a RAID Disk Drive Stripe Set
On systems such as the StudioZ RAX, you may create a stripe set for the RAID disk drives.
Intergraph Computer Systems recommends the following procedure after the system
hardware and software have been set up and configured for use.
To create a RAID disk drive stripe set:
1. From Windows NT Administrative Tools menu or program group, run Disk
Administrator.
2. When informed that the disk configuration has changed, click OK.
3. If asked to write a signature to one of the disks, click Yes. Repeat as many times as this
dialog displays.
4. A disk configuration window displays, showing the system drive and two unrecognized
drives (the RAID disk drives). Select both unrecognized drives by first clicking the
shaded rectangle representing one of the drives, then pressing
CTRL
and clicking the
shaded rectangle representing the other drive.
5. From the Partition menu, select Create Stripe Set.
