**************> QUESTION level 1 --> level 2 SPECIALIST <**************
Hi,
These question is related to the ability to use a remote systemguard
console with AIX on SMP systems.
This feature is only available if mirroring is activated after pushing
the system in maintenance level.
All works well if somebody is connectedon the console
and receive the mirror or if the console is off .
It is not possible to get this feature if the
console is in the getty position :
Message is : Warning mirrord : no log during mirroring
My questions are
1) Is it normal ? Is it a security feature ?
2) Can we use the flag : BUMP console = disable
to change this behaviour ? and allow a remote console in every
situation ?
What can be the consequences of this from the system management point
of view ?Are there potential negative effects on other features.
Greetings
D.LACAN

Response:
We can say that what you are experiencing is not normal. To change
this behavior we would suggest for to check the following below to see
if SystemGuard is properly configured. Basically the message is a
warning message probably due to a setting that is not configured
properly.
Console mirroring and dial-in support are available during the System
Guard Stand-By, Init and Run-Time phases. When mirroring is active,
the Service Console (S2 line) and the BUMP Console (S1 line) are
logically identical. If AIX is running, both are tty0 (tty1 is
disabled when mirroring starts). The Remote Console connection must
be established by dial-in when mirroring is active; the BUMP will not
dial out.
To enable console mirroring during the Standby and Init phases, the
following conditions must be met:
1) The Remote Authorization and Dial-Out Authorization flags must
be enabled. These flags can be set through the 'Set Flags' option in
the Stand-By Menu, or in AIX by entering mpcfg -cf 1 1 as the root
user. The Remote Authorization flag can also be enabled with the
'Enable Service Console' option in the Maintenance Menu.
2) Remote Service Support must be enabled and the Service Contract
Validity flag must be greater than or equal to 0. These flags can be
verified through AIX using the command mpcfg -dS as the root user.
3) The Service Line Speed must be set correctly. This can be set
through the 'Miscellaneous Parameters' option in the Maintenance Menu,
or with the command mpcfg -dm 2 . The baud rate chosen for
the Service Line Speed should match the rates set in the AIX tty1
definition, the Service Director 6000 forwarding host configuration,
and in the AIX file /etc/uucp/Devices.
4) Phone numbers must be set correctly. The phone numbers that
must be set are the Service Center Dial-Out (1), System Dial-In and
the System Operator Voice numbers. The Service Center Dial-Out number
is the same number that is used for Service Director (1-800-830-
1041). These can be set using the 'Set Parameters' and 'Phone
Numbers' options in the Maintenance Menu, or by using the command
mpcfg -dp to display the indexes for the phone numbers and then mpcfg
-cp to set the values for the phone number fields.
These commands must be issued by a root user.
Enabling console mirroring for the Run-Time phase is more involved,
since AIX is active. In addition to the above conditions, the
following additional conditions must be met:
5) The Software Error Logging Facility and Dump Service Aids
packages must be installed.
6) tty0 and tty1 should be defined according to the tables below.
7) The Modem Parameters Filename option must be set to /usr/share/
modems/mir_modem. This can be set through the 'Miscellaneous
Parameters' option in the Maintenance Menu, or in AIX by
entering mpcfg -cm 1 /usr/share/modems/mir_modem as the root
user.
8) The /usr/share/modems/mir_modem must exist, and be formatted in
the manner shown below.
NOTE: /usr/share/modems/mir_modem CANNOT be used as the Service
Director 6000 modem file
In order to start console mirroring, the System Key must be set to
Service (Physical Key in Service, or Physical Key in Normal and
Electro- nic Key in Service).
You will see this message:
mirrord: Wait connection
When remote support dials in, you will see this message:
mirrord: Remote user connected, mirroring active
Mirroring will stop when the System Key is set to Normal. You will see
this message:
mirrord: mirroring is stopped.
Thank you for using AIX Technical Support.
