ServerRAID Background-Server Components

ServerRAID Background-Server Components

This section provides information about background-server component command-line parameters and logging messages.

Command-Line Parameters

To use the command-line parameters provided in the background-server components, issue the IPSADM command in the following format:

IPSADM parameter1 parameter2 and so on...

Valid command-line parameters for the background-server components are as follows:

-?    The -? command displays the help for the valid parameters.
-p:number    The -p:number command specifies the port number
     that the server will check for client connections.
     The port number is a parameter used in TCP/IP to distinguish among different services on a single server.
     The default for the server utility programs is port number 1087.
     You can use this parameter to change the port number if another service on the system is using 1087.
-s:filename    The -s:filename command specifies the name of the file that
     contains security information. For more about security information, see
     (below) 'Background-Server Component Security'.
-f    The -f command specifies to log messages to the default file, IPSADM.LOG.
-f:filename    The -f:filename command lets you specify the name of
     a file in which to log messages.
-d    The -d command disables the logging of messages to the standard output, which is
     usually the screen.

Logging Messages

Messages generated by the ServeRAID adapter or controller consist of startup information, connecting and disconnecting clients, and error messages.

When using the -f, -f:filename and -d parameters, you can specify how you want the ServeRAID messages handled. The default is to log messages to the standard output, which is usually the screen. However, you can have these messages logged to other output devices, such as a printer or a text file.

The following information provides examples of different formats for using the IPSADM command and the results.

Command Results
IPSADM    Logs messages to the standard output and not to a file.
IPSADM -f    Logs messages to the standard output and to the IPSADM.LOG file.
IPSADM -f:NEWFILE.LOG    Logs messages to the standard output and to the file that you
     defined: NEWFILE.LOG.
IPSADM -d    Disables the logging of messages.
IPSADM -f -d    Logs messages to the IPSADM.LOG file, however, messages are not
     logged to the standard output.

Background-Server Component Security

Security information is maintained in an optional text file on the server. The file stores unencrypted user names and unencrypted passwords, therefore, the file must be kept in a secure directory.

When user names and passwords are entered into the Administration and Monitoring Program (the client), they are encrypted for delivery to the server. The server decrypts the user names and passwords to verify proper access to the ServeRAID adapter or controller. If the verification is successful, the adapter or controller accepts commands from the client. If no security file is present in the default directory, or the directory specified by the -s parameter, security is disabled. The server component then accepts commands from any client connection.

The security file contains one user name and password combination per line. The strings are separated by a colon (:) and each string has a maximum of eight characters.

Background-Server Component Name Resolution

The server component relies on name resolution to determine the host name from the client that is trying to connect. When a client is trying to access a remote server, the server tries to look up the name of the client connecting. The method used to look up the name is determined by the configuration of the server. Some possible methods for this are Domain Name Servers (DNS) or HOSTS files. With certain configurations, some timing delays might occur due to misconfiguration or inability to access the DNS. If problems persist, check your network configuration.
