The XSCFU has a serial port and LAN port as external interfaces. A terminal such as a personal computer or workstation can be connected to the XSCF through a serial connection or Ethernet connection.
The servers can be operated and managed from the command
Only the XSCF shell can be used through the serial connection. Both the XSCF shell and XSCF Web pages can be used through the Ethernet connection.
Note – The XSCFU supports a redundant configuration (duplicate configuration) for high reliability.
The XSCF that is currently in control of the server is called the active XSCFU, and the other XSCF is called the standby XSCF or standby XSCFU since it serves as the backup XSCF to the active one.
The active XSCF and standby XSCF monitor each other to implement a failover mechanism to switch between the active XSCF or standby XSCF when one of them detects and error in the other.
For details on functions provided by the XSCF, see Section 3.2.2, “XSCF Functional Overview” on page
The XSCF shell is a command
With the serial connection, the terminal is connected directly to the server to use shell commands provided by the XSCF. Also, the console redirection function of the XSCF enables the terminal to be used as an operating system console.
With the Ethernet connection, the terminal is connected to the XSCF via Secure Shell (SHH) or telnet to use shell commands provided by the XSCF.
The following are the main operations that can be performed with the XSCF shell:
■Display the server configuration or status and various related settings
■Display the domain configuration or status and various related settings
■Start or shut down a domain
■Make settings for various network services
■Make settings for various security functions
