Driver Installation

There are two methods of installing the PERC 2/SC Windows NT drivers:

Installing a new Windows NT 4.x server
Adding to an existing installation

Adding to Existing Windows NT

If you are already running Windows NT and want to add the PERC 2/SC Windows NT Driver and Utilities, insert the PERC 2/SC Windows NT driver diskette into diskette drive A (or B).

In the Control Panel, double-click the SCSI Adapters icon and then select the Drivers tab. Click Add and click Have Disk. Specify the location of the PERC Windows NT driver and click OK. Follow the instructions on the screen to add the PERC Windows NT driver.

This procedure will install the PERC 2/SC drivers for Windows NT 4.0. You must reboot the computer after PERC 2/SC Windows NT driver installation is completed successfully.

Configure Logical Drive

Logical drives can be configured on the PERC 2/SC SCSI adapter via the PERC Console, a GUI RAID management utility. The logical drives can be configured in Windows NT using Disk Administrator. See the PERC 2/SC Configuration Software Guide for additional information.

Making PERC 2/SC the Primary Controller in Windows NT

Perform the following procedure to install Windows NT from a bootable CD. The CD-ROM drive must be connected to an IDE or non-PERC SCSI port. This procedure will make the PERC 2/SC controller the primary RAID controller.

Insert the Windows NT installation CD into the CD-ROM drive before booting Windows NT. The Adaptec RAID adapter card detects a bootable CD and loads the bootable BIOS into memory.
When Windows NT begins to boot, press <F6> immediately when you see the message CD Setup is inspecting your computer's hardware configuration.
Within a few seconds a screen appears that asks for additional adapters in the system. Choose <S> and then press <Enter> on the OTHER option in the selection screen.
Insert the PERC 2/SC Windows NT Driver diskette into the diskette drive and press <Enter>. PERC NT SCSI DRIVER appears in the middle of the screen. Press <Enter> to load the driver. Press <Enter> again to continue operation as usual. Loading Windows NT in this manner tells the operating system that the PERC 2/SC controller is the primary controller. Windows NT continues to be installed as usual.

Installation On a New Windows NT 4.x Server

The installation process includes:

Installing hardware
Partitioning and formatting a SCSI hard-disk drive
Installing software
Configuring SNMP support

NOTE: You may have to refer to additional information in the appropriate guide.

Installing Hardware

Using FlexRAID Virtual Sizing With Windows NT

Dell recommends that you disable the FlexRAID Virtual Sizing option before installing Windows NT. Enable FlexRAID Virtual Sizing after you install Windows NT. If you install Windows NT with Virtual Sizing enabled, the Windows NT Setup Utility may show a larger partition size for installation than is actually available.

NOTE: Windows NT will not permit you to enter a partition size larger than 4096 MB during operating system installation.

Calculating Drive Partitions and Volumes

NOTE: In the following formulas, N represents the number of drives. A 2-GB drive is 2038 MB, a 4-GB drive is 4088 MB, and a 9-GB drive is 8568 MB.

Use one of the following formulas to calculate the size of the partition or volume:

RAID 0 — N x drive size = x MB of free space.
For example, if you have (2) 2-GB drives in a RAID 0 configuration, the calculation is 2 x 2038 = 4076 MB.

RAID 1 — N/2 x drive size = x MB of free space.
For example, if you have (2) 2-GB drives in a RAID 1 configuration, the calculation is 2/2 x 2038 = 2038 MB.

RAID 5 — N-1 x drive size = x MB of free space.
For example, if you have (3) 2-GB drives in a RAID 5 configuration, the calculation is (3-1) x 2038 = 4076 MB.

You must create a partition on the entire virtual space. However, volumes can be created using only the total capacity of the actual physical drives.

Adding Capacity Under Windows NT 4.x

Adding a drive to an existing array can only be achieved under the following conditions:

Virtual Sizing is enabled in the PERC 2/SC BIOS Configuration Utility.
The FlexRAID Power Fail Option is enabled.
Only 1 logical drive can be configured per array.
Drives can only be added to RAID levels 0 and 5.
New drives are added to the SCSI bus or to a SCSI subsystem.

Adding Drives Under Power Console

To add drives under Power Console, follow these steps:

On the main Power Console screen, verify that the added drive is displayed on the correct channel.
On the logical drive display bar above the channel display, right-click the Logical Drive icon.
Select Advanced and then select Add Drive. The Enhanced Logical Drive GUI is displayed.
Click the drive(s) you wish to add to the existing array. You can not exceed 8 physical drives in 1 array. Stripe Size cannot be changed.
Change the RAID level if desired. Click Apply and the array will be rebuilt. After the rebuild process is completed, use the Windows NT Disk Administrator to implement the additional space.

Applying Additional Space to the Windows NT Disk Administrator

To apply additional space to the Windows NT Disk Administrator, follow these steps:

After the rebuild process, run the Disk Administrator Utility.
The Disk Administrator will show at least 1 hard disk drive size of 81,917 MB.
To apply the new space to the Disk Administrator, you can add a new logical drive using Create, Create Extended Partition, or Extend Volume Set.

Adding a new Logical Drive using Create or Create Extended Partition

Right click available space next to the existing logical drive.
Select Create or Create Extended.
Enter the size of the additional space (the capacity of the hard-disk drive that was added).
Right click and choose the Commit to Changes button.
Right-click the new partition and format (recommended if using NTFS).
The drive is ready to be accessed without rebooting.

Adding a new Logical Drive using Extend Volume Set

This option is only available when you are using NTFS. It is not available under FAT.

Click the existing partition, and then hold down the <Shift> key and right-click the available space.
Click Extend Volume Set from the pull-down menu.
Type the total space of both partitions and total size of the volume.
For example, if the first partition is 500 MB and the new capacity of the array is 1000 MB, the volume size is 1500 MB.

NOTE: Windows NT requires you to reboot when you are exiting Disk Administrator.
