MPE/iX A-Class and N-Class Console

Console mirroring

Users of the GSP are categorized with two sets of capabilities.

A console Operator can use the system’s console, manage the system when a problem

occurs (rebooting it, etc,...), diagnose system failures through GSP logs and allow a

pre-conﬁgured remote console to connect. This is the usual set of capabilities required to

operate and manage a system. A console Administrator has the additional abilities to set

up the GSP conﬁguration in order to allow correct system operation and management.

This mainly includes conﬁguring login/password and access control and system monitoring

features. Once all the conﬁguations are complete the system can be fully operated and

managed with the Operator capability only.

There are a set of mirroring rules that control what each class of user can do and see while

other users are connected at the same time. For example if an operator is the ﬁrst to log in

to the GSP and then an administrator connects, only those commands allowed the operator

are available. If an administrator is the ﬁrst to log on to the GSP and then an operator

connects, the operator will have NO mirroring output.

NOTE If the administrator is connected at a port other than at the local console, the

local console is not available. The administrator must disconnect to re-allow

access to the local console. If necessary, the remotely connected administrator

can be forcebly disconnected by pushing a small reset button on the rear of

the system on the Core I/O card.

When enabled, and a user connects to the remote port and/or GSP LAN port, the GSP will

mirror console activity to connected users. There is always only one user that has the

ability to enter commands. All other connected users will see a message telling them they

don’t have write access. Write access can be obtained by entering the characters ^Ecf

(Ctrl-E cf) within 3 seconds.

Password protected access

All access to the GSP can be protected by username and password authentication. The

users can also be conﬁgured so that they are allowed only one successful logon. If so

conﬁgured, when they logoff, the GSP administrator must re-enable access if they want to

allow access to that user.

Session ldev

The remote serial port can create a session on a separate ldev. For example, if an ldev is

conﬁgured on the proper path in Sysgen and NMMGR (typically ldev 21) and remote

console access is disabled in the GSP, then a user would log on to that ldev, when they

connected to the port. In this case, no GSP access is available. If remote console is enabled

and the user is mirroring the console on the remote port, the GSP command ‘SE’ will

suspend console mirroring and establish a connection to the conﬁgured ldev.

Remote power up/down

From the GSP interface, the user can power up or down the system. This feature is

available unless the front panel switch is turned off. The function behaves almost like the

user turned off the front panel switch.
