Start Serial Console Redirection and Log In to Host Server OS

Language:

Before You Begin

Console (c) role is required in Oracle ILOM to launch a serial redirection session to the host server operating system.

Note - For Oracle's Sun servers supporting the Oracle ILOM Remote System Console Plus client, the read-write and view-only modes in an Oracle ILOM CLI host console (HOST/console) session are determined by the serial-line redirection setting in the Oracle ILOM Remote System Console Plus client window. For instance, when full-control mode is enabled for serial-line redirection in the Oracle ILOM Remote System Console Plus client window, all active CLI host console sessions will be forced to view-only mode. To regain read-write mode in the CLI host console session, the primary KVMS user must relinquish full-control in the Oracle ILOM Remote System Console Plus client window, and then restart session (by typing start -f /HOST/console).
Review Host Serial Console Log Properties. Also, for SPARC multi-domain servers, see Figure 54, Table 54, Host Status History Log for SPARC PDomains .
Host server user credentials are required to access the host operating system. Users should log out of the host operating system prior to terminating the host redirection session from Oracle ILOM.
Host console serial redirection sessions can be started from an Oracle ILOM SP CLI, or by using the serial redirection mode available in the Oracle ILOM Remote System Console Plus.

Note - Solaris users must use serial-redirection to access the Solaris Host Console, view Solaris Host Console messages, or to issue Solaris Host Console commands such as boot commands. Video redirection must not be used to access the Solaris Host Console, view Solaris Host Console messages, or to issue Solaris Host Console commands such as boot commands.

To start a host serial redirection console from the Oracle ILOM SP CLI, perform one of the following:
- For single host server SP, type:
  
  start /host/console
- For multi-domain SPARC server SP, type:
  
  start /Servers/PDomains/PDomain_n/host/console
A message appears prompting you to specify user credentials.

Type the required user credentials to access the host server operating system.
You are now logged in to the host server operating system through the host serial console.

Note - To issue standard Oracle ILOM CLI commands, you must first exit the host serial console.

To terminate the host redirection session, perform the following:
1. Log out of the host server operating system.
2. To terminate the connection between the host serial console and Oracle ILOM do one of the following:
  - For x86 systems, press these keys together: ESC and (
  - For SPARC systems, type #.
Note - To send a break to the host, press the Escape key and type uppercase B.

Host Serial Console Log Properties

Oracle ILOM provides a set of properties that enables system administrators to configure 1) how the host serial console history log appears, and 2) which escape characters are used to terminate the host serial console redirection session. For descriptions of these properties, see the following tables (Figure 53, Table 53, Host Serial Console Log Properties or Figure 54, Table 54, Host Status History Log for SPARC PDomains )

Note - CLI paths for multi-domain servers are not specified in the following Host Serial Console Log Properties table. For these type of SPARC servers, append /Servers/PDomains/PDomain_n to the start of the CLI paths described in the following table.

Table 53 Host Serial Console Log Properties

User Interface Configurable Target and User Role: SP CLI: `/HOST/console` ( or, `/Servers/PDomain/PDomain_n/Host/console`) User Role: Admin (a) role is required to modify the `logging` and `escapechars` properties. Console (c) role is required to modify the `line_count`, `pause_count`, and `start_from` properties.
Property	Default	Description
`logging`	enabled	`enabled`\|`disabled` Set the `logging` property to turn on or turn off serial console history logging. If the logging property is set to disabled, the `show /HOST/console/history` command will return the following error: `failed. could not get console history` CLI Syntax for `logging`: Single host server: `set /HOST/console logging=enabled\|disabled` Multi-domain host server: `set /Servers/PDomain/PDomain_n/HOST/console logging=enabled\|disabled`
`line_count`	0	Integer between 0 and 2048 Specify how many lines of the serial console history log to display. A value of 0 instructs Oracle ILOM to display the entire history log. CLI Syntax for `line_count`: Single host server: `set /HOST/console line_count=0 to 2048` Multi-domain host server: `set /Servers/PDomains/PDomain_n/HOST/console line_count=0 to 2048`
`pause_count`	0	`Integer between 0 and 2048` Specify how many lines of the serial console history log to display at once. After the specified number of lines have been displayed, Oracle ILOM will prompt you to continue: `press any key to continue or ???q' to quit` A value of 0 instructs Oracle ILOM to display the entire history log at once. CLI Syntax for `pause_count`: `set /HOST/console pause_count=0 to 2048`
`start_from`	end	`beginning`\|`end` Set the `start_from` property to instruct Oracle ILOM whether to display the serial console history log from the beginning or from the end. CLI Syntax for `start_from`: Single host server: `set /HOST/console start_from=beginning\|end` Multi-domain host server: `set /Servers/PDomains/PDomain_n/HOST/console start_from=beginning\|end`
`escapechars`	`#.`	Specify the escape characters used to exit the console redirection session. CLI Syntax for `escapechars`: Single host server: `set /HOST/console escapechars=``characters` Multi-domain host server: `set /Servers/PDomains/PDomain_n/HOST/console escapechars=``characters` Note - The `escapechars` property is only available for SPARC systems.
`timestamp`	`no` (display is disabled)	no (default_\| yes To display timestamp entries in the console history log from an x86 server SP, set the timestamp property to `yes`. CLI Syntax for `timestamp`: `set /HOST/console escapechars=``yes\|no` Note - The `timestamp` property is only available on x86 servers as of firmware release 3.2.5 or later.
`history`	N/A	View host console log history. CLI Syntax for `history`: Single server: `show /HOST/console/history` Multi-domain server: `show /Servers/PDomains/PDomain_``n``/HOST/console/history`
