Driver/Utility Files

The Novell NetWare driver and utilities support RAID logical drives.

	WARNING: The logical drives configured on the host adapter are registered with the operating system as separate logical units on Target ID 0.

Driver Installation

All utilities expect the driver to pass the requests to the adapter. The driver must be loaded before it can load the NLMs. Perform the installation in this order:

1. Load either PEDGE4_XX.HAM or PEDGE4XX.DSK driver, but not both.
2. Load DELLMON.NLM and DELLMGR.NLM.

Follow the instructions in the Novell NetWare installation guide to install NetWare on the server. If you are installing Novell NetWare, PERC 2/SC is the primary adapter.

1. Connect the hard-disk disks and CD-ROM (if you are installing NetWare from a CD-ROM) to PERC 2/SC. Configure PERC 2/SC and initialize all drives by running PERC 2/SC BIOS Setup or PERC 2/SC Manager. See the PERC 2/SC Configuration Software Guide for additional information.
2. Create a small active MS–DOS� partition on the first logical drive. Format the drive and transfer MS–DOS to that drive. Boot from this drive connected to PERC 2/SC. This drive should appear as drive C.
3. If you are installing the operating system from a CD, you may need MS–DOS CD-ROM drivers. Install the CD-ROM drivers and make sure that the CD-ROM drive can be accessed from MS–DOS.
4. Follow the Novell NetWare 4.11 installation instructions. Insert the PERC driver diskette when prompted. Novell NetWare automatically copies the files that it needs.
5. After rebooting, run NetWare. Load the PERC 2/SC NetWare utilities and files by typing A:RAIDINST at the NetWare prompt and pressing <Enter>.

Special Requirements for Multiprocessor Servers

If you are running Novell NetWare on a system with multiple processors, copy the SMP.NLM file to the NWSERVER directory and add the following line to STARTUP.NCF:

LOAD MPS14.PSM -V -FA

Installation On a NetWare 4.11 Server

FlexRAID Virtual Sizing

You must enable FlexRAID Virtual Sizing by running the PERC BIOS Configuration Utility before installing Novell NetWare 4.11x. When FlexRAID Virtual Sizing is enabled, the NetWare installation utility displays a larger partition size for installation than is actually available.

Use the VS=[size] parameter when loading the pedge4xx.dks driver during the installation process to adjust the virtual size partition. Valid partition sizes range from 32 to 1024 GB. For example, load pedge4xx.dsk vs=80 allows expansion of the array to 80 GB.

Calculating Drive Partitions and Volumes

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

NOTE: In the following formulas, N is 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.

• 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.

10. Highlight Yes and save the changes.
11. Mount all volumes. The additional space can be accessed without rebooting.

Loading NetWare SNMP

After the NetWare SNMP is installed, it loads automatically when the server starts. You can also explicitly start NetWare SNMP by typing the LOAD command. Type LOAD SNMP options and press <Enter>. The options allow you to establish the community name used in SNMP traps. NetWare SNMP also provides community name defaults for the monitor (read-only) and control (read/write) communities. NetWare SNMP uses these names for access control. The community names in a request message from an SNMP management station must match the names established by NetWare SNMP.

If NetWare SNMP receives a request protocol data unit (PDU) that has an unknown community name, it does not respond to the request. For example, if the community name is secret and NetWare receives a SETRequest PDU with the community name public, NetWare SNMP discards the SETRequest PDU and does not respond.

Disabling Community Types

When a community type is disabled, no management entity can access information for that community. For example, if the control community is disabled, no one can use NetWare SNMP to do SET operations on the data that NetWare manages.

Changing Options

You can change options by typing the LOAD command while NetWare SNMP is running. You can also modify the LOAD SNMP line in the AUTOEXEC.NCF file to include different defaults.

NetWare LOAD Command Options

The NetWare LOAD command line options are not case-sensitive. Just type the first character of the option name. The communityName is an arbitrary 1-32 character, case-sensitive ASCII string that can include any character except a tab, space, [, ], =, :, :, or #.

Enabling Access by Single Community Name

Enter the option parameter followed by an equal sign and the community name. Thereafter, the community name offered by the SNMP management station must match this new community name; otherwise, NetWare SNMP will deny access.

Enabling Access by Any Community Name

Enter the option parameter followed by an equal sign and no community name. Thereafter, any community name offered by the SNMP management station is accepted by NetWare SNMP.

Disabling Access to a Community

Enter the option parameter with no equal sign.

Manually Configuring NetWare SNMP for MIB-II Information

You can set several MIB-II variables in the SYS:\ETC\SNMP.CFG file. Edit the SYS:\ETC\SNMP.CFG file using any ASCII text editor. Follow the instructions in the file comments.

Manually Loading PEDGESNMP.NLM

PEDGESNMP.NMM is automatically loaded when the PERC 2/SC Novell NetWare driver is loaded. You can manually load it using the following procedure:

1. Compile the SNMP MIB from the SNMP Manager workstation.
   No compilation is necessary from the NetWare server.
2. Load PEDGESNMP.NLM after SNMP.NLM has been loaded. Type the following command at the MS–DOS prompt to enable Set and Traps:

LOAD SNMP Trap = Control = verbose

3. Load PEDGECSNMP.NLM and edit SYSTEM:\ETC\TRAPTARG.CFG to include the IPX addresses of the workstations running SNMP Managers.

Configuring NetWare to Send Traps to Applications

To receive traps sent by NetWare SNMP, make sure your management station address is listed in the IP or IPX section of the SYS:\ETC\TRAPTARG.CFG file. You can edit the file using any ASCII text editor. Follow the instructions in the file comments.
