Dell™ PowerEdge™ Expandable RAID Controller 3/Di INSTALLATION GUIDE

Configuring the PERC 3/Di Remote Agent for NetWare

If you have problems installing or using the PERC 3/Di controller and the SCSI devices attached to it, consult the following list of troubleshooting suggestions:

Does the PERC 3/Di BIOS banner (similar to the following) appear during bootup?

Dell PowerEdge RAID Controller 3/Di, V2.7Build XXXX
(c) 2002 Adaptec, Inc. All Rights Reserved

If the banner appears, it indicates that the system recognizes the PERC 3/Di as part of the hardware configuration. If it does not appear, check that you have enabled the PERC 3/Di. For information on how to enable your PERC 3/Di, see your Dell PowerEdge manual that covers Activating the Dell PERC 3/Di.

Are the SCSI buses terminated properly and are all SCSI devices turned on?
Are all SCSI bus cables and power cables connected securely? Be sure to carefully check the pins in the 68-pin cables.
Does each device on the bus have a unique SCSI ID? If the controller will not boot, power off all disks and attempt to reboot. If the system boots and it is the first time the disks are connected, it is likely that the SCSI ID's are set incorrectly.
Does the controller appear in the FAST or Array Manager open dialog? If not, check the System Event Log report for any errors reported by the controller. To do this from the Start menu, press Start> Programs> Administrative Tools> Event Log.
If containers are not recognized as valid devices on a NetWare system, ensure that the SCSIHD.CDM custom device module is loaded before the perc2.ham driver in the STARTUP.NCF file. (The NetWare 5.1 installation procedure enforces the loading of CDM files before HAM files, whereas earlier versions did not.)
Did the PERC 3/Di pass self-test? If not, a message similar to the following will appear on boot-up:

WARNING! The PERC 3/Di selftest has failed.

Contact your technical service representative to determine the cause of failure and to see if a replacement controller is required.

Using the Controller Service Features

The PERC 3/Di BIOS provides a Controller Service utility that enables you to view a detailed log of BIOS events and change some advanced BIOS settings. This utility should be accessed in cases where your PERC 3/Di controller will not start because of a configuration problem.

Caution: The Controller Service utility is intended to assist technical support representatives in troubleshooting controller problems; it should not be used under normal operating conditions.

To access the Controller Service utility:

Press Ctrl-A when the following prompt appears when you turn on or reboot your server:

Press <Ctrl><A> for Configuration Utility!

If multiple controllers are installed, select the controller you wish to configure and press Enter.
Press Ctrl-P to start the Controller Service Utility. A two-option menu appears.
Select Additional Controller Configuration to access advanced BIOS settings or select Controller Log Information to view detailed information on the current BIOS log and the previous BIOS log and press Enter.

Controller Log Information

If you are experiencing system problems, your Dell technical service representative can access the controller log to gain detailed information on the internal operations of the PERC 3/Di during the current boot and the previous boot.

Controller Configuration Options

The Controller Service utility provides the following options:

Force Single Container Configuration — If Enabled, this option causes the PERC 3/Di to configure only the boot container to be able to boot; any other containers are ignored. The default is Disabled. Use this option if you encounter problems booting the controller because of problems with containers other than the boot container.
Boot Mode — This option sets the mode for the next boot. If Normal, then all of the containers and files systems will be configured (if possible) during system boot. If Maintenance, then none of the containers or file systems will be configured. The default is Normal. Maintenance mode allows the system to be started in cases where you are experiencing PERC 3/Di problems and cannot otherwise boot your system.
Clear NVRAM — This option is available only for controllers that have a battery. When Enabled, this option clears the PERC 3/Di NVRAM (nonvolatile DIMM) of its contents. The default is Disabled.

Caution: Clearing the NVRAM can have serious consequences! Loss of data occurs if the NVRAM is cleared when it contains valid data which has not been written to disk. Only an authorized individual should clear the NVRAM.

Configuring the PERC 3/Di Remote Agent for NetWare

The NetWare PERC 3/Di remote agent allows you to disable remote access, permit read-only access and require a remote user to supply a password before allowing a remote connection. You can configure the PERC 3/Di remote agent by editing the fsasrvnw.nlm file. To edit the file, type load edit fsasrvnw.ini at the NetWare console prompt. Make the desired changes to the .ini file and exit the editor (see Access and Communications for settings). After the file has been edited, restart the fsasrvnw.nlm application so that the software recognizes that configuration changes have occurred. To do this, type unload fsasrvnw followed by load fsasrvnw at the console prompts.

Note: In Windows NT, the PERC 3/Di remote agent can be configured through a control panel application or through the Windows NT Registry. Refer to the Flexible Array Storage Tool User's Guide for more information.

Access

The access section determines how or if a remote user is allowed to open a PERC 3/Di controller. The access section contains the following flags:

Read-write — If this field is set to TRUE, remote read-write access will be allowed. If this field is set to false, no remote users will be allowed to open controllers in read-write mode.
Remote-access — If this field is set to TRUE, remote access will be allowed. If this field is set to FALSE, no remote access will be allowed.

Note: The read-write password setting and read-only-password setting in fsasrvnw.ini are case sensitive.

Read-write-password — If this field is set to TRUE then users opening controllers read-write remotely will be required to provide a password to gain access to the controller. The user will be prompted for a username and password. The user must supply a username and a password for an account on the NetWare server that has supervisor privileges. The setting is case sensitive.
Read-only-password — If this field is set to TRUE then users opening controllers read-only remotely will be required to provide a password to gain access to the controller. The user will be prompted for a username and password. The user must supply a username and a password for an account on the NetWare server that has supervisor privileges. The setting is case sensitive.

Communications

The communications section provides switches that control how communication will be configured. The communication section contains the following switches:

Use_IP — If this switch is set to TRUE, the PERC 3/Di Remote Agent will attempt to use IP as a communications protocol.
IP_PORT — This switch specifies (in decimal) the IP port that will be used for communications. This may be helpful if you are trying to access the controller through a firewall. The IP_PORT is specified as a four-octet address, for example, 128.10.2.30.
Use_IPX — If this switch is set to TRUE, the PERC 3/Di Remote Agent attempts to use IPX as a communications protocol.
IPX_SOCKET — This switch specifies (in decimal) the IPX socket that will be used for communications. This may be helpful if you are trying to access the controller through a firewall. The IPX_SOCKET is specified as a hexadecimal address; for example, 4640E44D.000000000001.
Client_timeout — This switch specifies (in seconds) the amount of time that the software will allow to expire before closing communications with the client.
