NOTE: For version 4.1, the corresponding fileset would be netware.server for NetWare Server Code v3.11b.
There are three files that need to be changed for configuration of NetWare. These files are:
These files can be edited manually, or you can use /usr/lpp/netware/bin/sconsole to configure NetWare.
The file /etc/rc.netware starts NetWare. This file loads the STREAMS drivers needed to start NetWare. If TCP/IP is not configured on the system, then uncomment the lines associated with the interface. By default, these interfaces have a "0" at the end. Make sure that these numbers match the interface that will be used for NetWare. The number may be different if there are multiple token ring or Ethernet adapters in the system. Use the netstat -i command to see what interfaces are currently configured on the system.
Example from /etc/rc.netware:
# /usr/sbin/ifconfig en0 up # /usr/sbin/ifconfig et0 up # /usr/sbin/ifconfig tr0 up
The /etc/netware/NWConfig file contains the NetWare file server name and other tuning-related parameters. In most cases, only the file_server_name needs to be set in this file for NetWare to work. The default name is PORTABLE, which should be changed to a name that will distinguish the IBM eServer pSeries or RS/6000 machine from other possible NetWare servers on the network. It is also recommended to change the console_flag parameter from inactive to active. This will allow messages to be echoed to the system console.
The /etc/netware/NPSConfig file contains the network-related configuration. This file determines what network adapter card(s) and network numbers are used. It also lists which daemons to activate when NetWare for AIX is started. By default, NetWare for AIX has SAP active and SPX and NVT inactive. If NVT is activated, then the nvt_server_name should also be set. The nvt_server_name does not have to be the server host name. SPX is needed for printing in a Novell NetWare network and should be active if printing is configured. The internal_network number is also set in this file. This number should be changed and should be a unique eight-digit number. The last eight digits of a system's hardware address make a good unique "internal_network" number.
By default, NetWare for AIX is configured for the Ethernet Version 2 interface. There are sample configurations for the other possible interfaces (commented out) near the end of the /etc/netware/NPSConfig file.
Here is an example of the network configuration part of the /etc/netware/NPSConfig file:
lan_1_network = "e2e2e2e2" lan_1_adapter = "/dev/dlpi/en" lan_1_adapter_type = "ETHERNET_DLPI" lan_1_ppa = 0 lan_1_if_name = "en" lan_1_frame_type = "ETHERNET_II" lan_1_module = "NULL"
Once all changes have been made to the configuration files, the command /etc/rc.netware will start NetWare. Verify that the NetWare daemons are running with the command ps -ef and grep for the following six daemons:
To make changes to the configuration, always stop NetWare first. The command /etc/netware.clean can be used to stop NetWare. Verify that the NetWare daemons have stopped by running ps -ef and grep for the six daemons listed above. If nvt is not configured, the ./nvtd daemon will not be running.
NetWare can also be configured, started, and stopped using the sconsole utility on AIX. This is a better way to configure NetWare for AIX if you are not comfortable using the vi editor. You will need to log on as root on AIX in order to run the sconsole utility. It is located in the /usr/lpp/netware/bin directory.
This section contains information that is relative to any user's configuration and should be interpreted and integrated into each user's situation. There is no guarantee for the actual performance your system will reach when configuring a NetWare server under these guidelines.
These guidelines have been used in other systems, and certain performance characteristics such as response time and speed were improved with these changes. The default values in the /etc/netware/NWConfig file will work; however, some variables, such as number of users, application types, volume size and depth, or system demand place the NetWare server under various strains which may be relieved with a change to this file.
The optimum number of users per NCP engine (also called an NW engine) varies somewhat with system capacities and other site-specific factors. However, as a general rule, a ratio of 10 users per NCP engine should be maintained. Other ratios can be used but performance may suffer. Even having less than 10 users per engine may decrease performance because there will be more engines competing for system resources. The examples below can serve as a template which might apply to your system's configuration. The shared memory variables should be increased to avoid memory errors. The default value is 512*1024. A good value to use is 2048*1024. The file system cache blocks value should be increased to aid in cache performance. The default value is 28 and the maximum is 80. Forty to 60 is suggested depending on usage.
Edit the /etc/netware/NWConfig file and make the following changes that would best apply to your configuration:
Configuration #1 (10 users, 1 server, 1 network, normal usage on PCs (file editing)):
max_procs = 1 max_connections = 10 max_volumes = 64 shm_size = 2048*1024 fs_shm_size = 2048*1024 fs_num_cache_blocks = 40
Configuration #2 (10-20 users, 1 server, 1 network, normal usage on PCs (file editing)):
max_procs = 1 (possibly 2) max_connections = 20 max_volumes = 64 shm_size = 2048*1024 fs_shm_size = 2048*1024 fs_num_cache_blocks = 40
Configuration #3 (40-50 users, 1 server, 1 or more networks, heavy usage (file editing, database usage, file transfers etc.)):
max_procs = 5 max_connections = 50 max_volumes = 64 shm_size = 4096*1024 fs_shm_size = 4096*1024 fs_num_cache_blocks = 60
NOTE: Changes to the /etc/netware/NWConfig file do not take effect until NetWare is stopped and restarted.
NVT can be configured for AIX with sconsole or by editing the /etc/netware/NPSConfig file. The sconsole utility changes the NPSConfig file in a menu driven style.
The following changes to NVT parameters need to be made.
A number of different NetWare configurations can exist between the pSeries or RS/6000 server, PC workstations, and a Novell NetWare server. This section highlights one possible configuration and should provide sufficient information to address problems with different configurations.
The C:autoexec.bat file should have the following line to log in to the server:
This should be the last line in this file and follow the f: drive specification. The "<servername>" is the same name used in the /etc/netware/NWConfig file for the NetWare server.
When the PC is booted, there should be messages regarding connections to the NetWare server as follows:
Attached to server... You are attached to server <servername> Good afternoon, supervisor.
The prompt should look like F:\SYSTEM> .
If you run logout at the F:\SYSTEM> prompt, you will receive the message SUPERVISOR logged out from server <servername> connection 1 and the system prompt will look like F:\LOGIN>.
If you do not get attached to the NetWare server, you should receive the message Server <servername>....The specified server is unknown. The prompt will look like F:\LOGIN>.
Once attached to the NetWare server, with the F:\SYSTEM> prompt, you should be able to run the DOS/OS2 executables found in this directory. Other utilities like slist and syscon can be found in the F:\PUBLIC> file system.
NOTE: On the pSeries or RS/6000 server, run ls -alF /opt/netware/sys/system. This will show ownership of all files and subdirectories as netware.netware. Any files copied or restored using ftp or mksysb will not have netware.netware ownership. For files or subdirectories not owned by netware.netware, run chown netware.netware <filename>. This changes owner and group to netware. The permissions for various files and subdirectories in /opt/netware/sys/system range from 600, 644, 700, to 755. The user portion of the permissions field must be "rw" (6) or "rwx" (7).
NWError 0x1, NWDMain verify dirs, bad system value, invalid /system directory
cannot mount volume
NWERROR:(0XFF) Setup memory creating shared memory...
This error occurs when netware daemons are running and a second startup of netware occurs. You can avoid this error by verifying that the netware daemons are not running (see the daemon list in the section "Starting and stopping NetWare") before starting netware. If you already have the error, see the following solution.
T ID KEY MODE OWNER GROUP Shared Memory: m 0 0x0d050236 --rw------- root system m 151553 0x58067000 --rw-rw-rw- root system m 2 0x0d06b15b --rw-rw-rw- root system m 8195 0xba5eba11 --rw-rw---- root system m 8196 0xdead2bad --rw------- root system
Find the Shared Memory IDs for the segments 0xba5eba11 and 0xdead2bad. Delete these memory segments with the command:
ipcrm -m #where # is the ID number for these memory segments.
For the above example, ipcrm -m 8195 and ipcrm -m 8196 would be run.
See /usr/lpp/netware/README for details on nwfsck.
The NWFSCK utility is a consistency-check and interactive-repair utility for the NetWare file system. Use nwfsck to repair inconsistencies in the NetWare Inodes file; generate the Inodes file if the file is missing; and print statistics on items in the Inodes file (number of files, forks, directories, blocks).
Before running the NWFSCK utility, make sure:
The command nwfsck is located in /usr/lpp/netware/bin and the syntax is shown below.
nwfsck [options...] filename [volume_number (optional)] [mount_point (optional)]
The recommended flag options to use with this command are -yacf. The meaning of these flags is:
-y apply all corrections
-a automatic mode; used for volume creation
-c force checking of forks
-f force synchronization with host file system
If you do not include an option, the utility runs in interactive mode. If any inconsistencies are found, you determine which inconsistencies are fixed.
Replace filename with the complete path and name of the inodes file on the host system. The system administrator specified this name in the NWConfig file when the volume was created. The default for path and file name is /opt/netware/NWControl/sys/inodes. Other volumes will have different pathnames to the inodes file and the NWConfig file should be checked.
Replace volume_number with the number specified for the volume in the NWConfig file. If specified, the nwfsck utility verifies that the specified number matches the volume number in the header of the inodes file. This parameter is optional. If not specified, the number in the file system header is used.
Replace mount_point with the path on the host system that specifies the root of the NetWare volume on the host file system. The system administrator specified the path when the volume was created. Use the sconsole utility to view the path. This parameter is optional. If specified, the nwfsck utility verifies that the path matches the path in the header of the inodes file. If not specified, the path in the file system header is used.
