NAME

scadm - administer System Controller (SC)
 

SYNOPSIS

/usr/platform/platform-name/sbin/scadm subcommand [option] 
    [argument]...

DESCRIPTION

The scadm utility administers the System Controller (SC). This utility allows the host server to interact with the SC.

The scadm utility must be run as root.

The interface, output, and location in the directory hierarchy for scadm are uncommitted and might change.

platform-name is the name of the platform implementation. Use the uname -i command to identify the platform implementation. See uname(1).

The scadm utility has a number of subcommands. Some subcommands have specific options and arguments associated with them. See SUBCOMMANDS, OPTIONS, OPERANDS, and USAGE.  

SUBCOMMANDS

Subcommands immediately follow the scadm command on the command line, and are separated from the command by a SPACE.

The following subcommands are supported

consolehistory

Display the SC's console log. The SC maintains a running log which captures all console output. This log is maintained as a first-in, first-out buffer: New console output may displace old console output if the buffer is full. By default, only the last eight kilobytes of the console log file are displayed.

The optional -a argument specifies that the entire console log file be displayed.

It is possible for the SC to fill this log more quickly than the consolehistory subcommand can read it. This means that it is possible for some log data to be lost before it can be displayed. If this happens, the consolehistory subcommand displays "scadm: lost <number> bytes of console log data" in the log output, to indicate that some data was lost.

The format for the consolehistory subcommand is:

scadm consolehistory [-a]

The consolehistory subcommand is not available on all platforms. If this command is used on a platform that does not support it, scadm prints this message:

scadm: command/option not supported

and exit with non-zero status.

date

Display the SC's time and date

The format for the date subcommand is:

scadm date

download

Program the SC's firmware.

There are two parts to the firmware, the boot monitor and the main image.

By default, The scadm command's download programs the main firmware image. The boot argument selects programming of the boot monitor.

The format for the download subcommand is:

scadm download [boot] file

fruhistory

Display the contents of the "field replacable unit" log maintained by the SC. By default, only the last eight kilobytes of the fru history log file are displayed. The data in contained this log contains snapshots of the SC's "showfru" command, taken whenever the system is reset, or a hot-plug event is detected by the SC.

The optional -a argument specifies that the entire fru log file be displayed.

It is possible for the SC to fill this log more quickly than the fruhistory subcommand can read it. This means that it is possible for some log data to be lost before it can be displayed. If this happens, the fruhistory subcommand displays "scadm: lost <number> bytes of fru log data" in the log output, to indicate that some data was lost.

The format for the fruhistory subcommand is:

scadm fruhistory [-a]

The fruhistory subcommand is not available on all platforms. If this command is used on a platform which does not support it, scadm prints this message:

scadm: command/option not supported

and exit with non-zero status.

help

Display a list of commands.

The format for the help subcommand is:

scadm help

loghistory

Display the most recent entries in the SC event log. The optional -a argument causes the entire event log history to be displayed. The -a argument is available only on platforms which support large log files. On platforms which do not support large log files, this flag has no additional effect.

It is possible for the SC to fill this log more quickly than the loghistory subcommand can read it. This means that it is possible for some log data to be lost before it can be displayed. If this happens, the loghistory subcommand displays "scadm: lost <number> events" in the log output, to indicate that some data was lost.

The format for the loghistory subcommand is:

scadm loghistory [-a]

resetrsc

Reset the SC. There are two types of resets allowed, a hard reset and a soft reset.The hard reset is done by default. The soft reset can be selected by using the -s option.

The format for the resetrsc subcommand is:

scadm resetrsc [-s]

send_event

Manually send a text based event. The SC can forward the event to the SC event log. You can configure the -c option to send a critical warning to email, alert to logged in SC users, and syslog. Critical events are logged to syslog(3C). There is an 80 character limit to the length of the associated text message.

The format for the send_event subcommand is:

scadm send_event [-c] "message"

set

Set SC configuration variables to a value.

Examples of SC configuration variables include: SC IP address netsc_ipaddr and SC Customer Information sc_customerinfo. See the output from the scadm help command for a complete list of SC configuration variables.

The format for the set subcommand is:

scadm set variable value

show

Display the current SC configuration variable settings. If no variable is specified, scadm shows all variable settings.

The format for the show subcommand is:

scadm show [variable]

shownetwork

Display the current network configuration parameters for SC.

The format for the shownetwork subcommand is:

scadm shownetwork

The format for the userdel subcommand is:

scadm userdel username

userpassword

Set a password for the user account specified. This password overrides any existing password currently set. There is no verification of the old password before setting the new password.

The format for the userpassword subcommand is:

scadm userpassword username

userperm

Set the permission level for the user.

The format for the userperm subcommand is:

scadm userperm username [aucr]

The format for the version subcommand is:

scadm version [-v]

OPTIONS

The resetrsc, send_event, and version subcommands have associated options. Options follow subcommands on the command line and are separated from the subcommand by a SPACE.

The resetrsc subcommand supports the following options:

-s

Perform a soft reset instead of a hard reset. A hard reset physically resets the SC hardware. The SC software jumps to the boot firmware, simulating a reset, for a soft reset.

The send_event subcommand supports the following options:

-c

Send a critical event. Without the -c, -send_event sends a warning.

The version subcommand supports the following options:

-v

Display a verbose output of version numbers and associated information.

The consolehistory, fruhistory, and loghistory subcommands support the following option:

-a

Display the entire log. These subcommands normally display only the most recent log data. This flag causes them to display the entire log.

OPERANDS

The download, send_event, set, show, useradd, userdel, userperm, usershow, userpassword, and userperm subcommands have associated arguments (operands).

If the subcommand does not have an option, the arguments follow the subcommand on the command line and are separated from the subcommand by a SPACE. If there are more than one arguments, they are separated from each other by a SPACE.
