Important Software Notices
u
You must complete the Windows NT Server installation before using the system.
u
The RAID controller board has two types of write caching: write-back and write-
through. Write-through caching reduces the risk of data loss in the event of a power
failure. Write-back caching improves performance, but the drawback is potential data
loss if power is interrupted. Intergraph recommends connection to a UPS to guard
against data loss.
u
Intergraph configures the RAID controller board to RAID level 5. RAID controllers
support RAID levels 0, 1, 5, 6 (0+1), and 7. The MegaRAID controller, in addition to
the other levels, also supports RAID level 3.
To power on and configure the system:
1. Power on the InterRAID-12 cabinet and wait for the audible beep.
2. Power on the system base unit and the monitor.
3. Complete the Windows NT Server installation. Refer to the system’s setup or
configuration documentation.
4. Install the proper software utilities available for the RAID controller board installed in
the system.
For DAC960P and DAC960PD boards, install the DACADM and DACMON utilities.
Refer to Chapter 5, “Using DAC InterRAID Utilities.”
For MegaRAID boards, install the MegaRAID BIOS and Power Console utilities. Refer
to Chapter 6, “Using MegaRAID BIOS” and Chapter 7, “Using Power Console.”
WARNING
After you configure the RAID disk drives, it is very important that you backup the
configuration to a diskette. It will be very helpful for future use in the event the
configuration should become lost. Refer to Chapter 5 “Using DAC InterRAID Utilities,”
or Chapter 6 “Using MegaRAID BIOS” and Chapter 7, “Using Power Console.”
5. If necessary, configure the RAID controller board to your preferences. Refer to Chapter
5 “Using DAC InterRAID Utilities,” or Chapter 6 “Using MegaRAID BIOS” and
Chapter 7, “Using Power Console.”
6. Use Disk Administrator in Windows NT to partition and format the disk space not used
by the operating system. When prompted to create a Signature File, select Yes. Refer to
the Windows NT Server System Guide for information on using Disk Administrator.
