Sun Microsystems T6300 manual Access Through Multiple Controller Sessions

Page 25

Note – When you access the ALOM system controller for the first time and you issue an administrative command, you must create a password for the default username, admin, for subsequent access. After this initial configuration, you will be prompted to enter a user name and password every time you access the ALOM system controller.

For more information about navigating between the system console and the ALOM system controller, see “Obtaining the ok Prompt” on page 15

Access Through Multiple Controller Sessions

Up to nine ALOM system controller sessions can be active concurrently, one session through the serial port and up to eight sessions through the network management port. Users of each of these sessions can issue commands at the sc> prompt. For more information, see the following:

■“Accessing the System Controller” on page 3

■“Activating the Network Management Port” on page 4

Note – Only one user has active control of the system console at any time. Any additional ALOM system controller sessions afford passive views of system console activity, until the active user of the system console logs out. However, the console -fcommand enables users to seize access to the system console from one another. For more information, see the Advanced Lights Out Management (ALOM) CMT v1.3 Guide.
