Description
Sun Blade[TM] 8000 Chassis Monitoring Module (CMM) can operate in an Active-Standby redundant pair. To prevent setting conflicts, all configuration occurs on the Active CMM only and configuration variables transfer from Active to Standby upon a failover event. However, there are some variable settings that are specific to the local CMM only and must be set manually on each CMM to change them. These can only be set when that CMM is the Active and do not failover. This document describes these loc


Steps to Follow
The following CMM settings are specific to the local CMM ILOM and can only be set when the CMM is the Active CMM in the redundant pair. These settings do not failover from Active to Standby at any time. To set them, check to see whether the CMM is Active or Standby first, then if its Active, set the settings; if it is Standby then initiate a manual failover and then set them.
The local only CMM ILOM settings are:
  1. Clock date/time
  2. Serial port configuration
  3. CMM Hostname (ILOM v2.0.1.1 or later only)
  4. SSH (secure shell)  enable/disable
  5. Session Time-out for Inactivity (Web browser interface only)

To determine current Active/Standby state:

On Web, the Standby CMM initial screen will show only "Status: Standby" with options only to "Promote CMM", "Version Information" and "Firmware Upgrade". To initiate a manual failover so they can be set, click the Promote button and re-login.

On Web, the Active CMM initial screen will have the pictures of the chassis and left menu of available CMM and blades. These variables can be set now, when Active.

On the physical CMM, the green LED on the right labeled "MASTER" will be ON, on the CMM that is Active. The LED will be OFF on the CMM that is Standby.

On SSH (secure shell) or serial port command line interface (CLI):

-> show /CMM/redundancy
/CMM/redundancy
Targets:
   Properties:
fru_name = /CH/CMM0      <<<<<
initiate_failover_action = (none)
status = Standby         <<<<< 
   Commands:
cd
set
show
->

This document describes settings that only apply to CMM0 locally but cannot be set here when in Standby mode. Manually failover the CMM so that these local settings can be set, then login again:

-> set /CMM/redundancy initiate_failover_action=true
Set 'initiate_failover_action' to 'true'
-> Connection to cmm0 closed.
 workstation => ssh -l root cmm0

->  show /CMM/redundancy/
 /CMM/redundancy
Targets:
    Properties:
fru_name = /CH/CMM0    <<<<<
initiate_failover_action = (none)
status = Active        <<<<< 
    Commands:
cd
set
show
->

Now these settings can be set for CMM0.
Failover and repeat the setting of each of these variables on CMM1 when it is Active.

1. To set local clock date and time:

NOTE: It is preferred to configure date and time using NTP servers. If NTP is enabled, this overrides the local clock date/time and NTP settings are copied from Active to Standby so this issue does not apply in that scenario.

NOTE: ILOM currently does not support Timezones. All time settings are considered to be UTC.

On Web, click on "CMM" on left side list; then click "Configuration" tab and "Clock Settings" sub-tab. Un-check the NTP "Enabled" box. Enter the local date and time in the format specified.

On SSH/Serial port CLI where datetime string is in the format MMDDhhmmYYYY or MMDDhhmmYYYY.ss

-> set /CMM/clock datetime=091716002007
Set 'datetime' to '091716002007'
-> show /CMM/clock
 /CMM/clock
Targets:
   Properties:
datetime = Mon Sep 17 16:00:56 2007
usentpserver = disabled
   Commands:
cd
set
show
->

2. To set local serial port:

NOTE: Setting port speed to >9600 baud is only supported in ILOM v1.1.5 or later. Valid settings are 9600, 19200, 38400, 57600 & 115200.

NOTE: If you are connected to the serial port at the time of changing settings, you will also need to change your terminal settings and re-connect.

NOTE: CMM ILOM serial port (DB9 connector) ONLY supports changing of the speed. All other settings cannot be changed, they are always 8,N,1 with None flowcontrol (no software or hardware).

On Web, click on "CMM" on left side list; then click "Configuration" tab and "Serial Port" sub-tab. Select the desired speed and click the "Save" button.

On SSH/Serial port CLI:

-> cd /CMM/serial/external
-> set pendingspeed=115200
Set 'pendingspeed' to '115200'
-> set commitpending=true
Set 'commitpending' to 'true'
-> show
 /CMM/serial/external
Targets:
   Properties:
commitpending = (Cannot show property)
flowcontrol = none
pendingspeed = 115200
speed = 115200
   Commands:
cd
set
show
->

3. To set local CMM Hostname: (ILOM v2.0.1.1 and later)

NOTE: When connecting to the floating high availability CMM IP address, the web login screen will show the local CMM hostname of the current Active CMM. There is also a setting for "System Identifier" which is copied from Active to Standby.

On Web, click on "CMM" on left side list; then click "System Information" tab and "Identification Information" sub-tab. Enter the desired host name and click the "Save" button.

On SSH/Serial port CLI:

-> set /CMM hostname=<host name>
-> show /CMM
/CMM
Targets:
alertmgmt
cli
clients
clock
faultmgmt
logs
network
policy
powermgmt
redundancy
serial
services
sessions
users
   Properties:
hostname = SB8000-CH1-CMM0           <<<<< local only
system_identifier = SB8000-Chassis1  <<<<< copied redundant name
   Commands:
cd
reset
set
show
version
->

CMM Network IP Address:
In addition the local IP address for each CMM should be unique and will allow login to the specific CMM that is set to that IP, however this set for the Standby from the Active CMM.

On Web, click on "CMM" on left side list; then click "Configuration" tab and "Network" sub-tab. Select the button beside each CMM listed, then select "Edit" from the drop-down menu, and change the settings accordingly for each CMM0, CMM1 and high-availability CMM floating IP address.

On SSH/Serial port CLI:

-> cd /CMM/network/CMM0
-> show
 /CMM/network/CMM0
Targets:
   Properties:
commitpending = (Cannot show property)
ipaddress = 10.8.55.210
ipdiscovery = static
ipgateway = 10.8.55.249
ipnetmask = 255.255.255.0
macaddress = 00:03:BA:F1:3D:D6
pendingipaddress = 10.8.55.210
pendingipdiscovery = static
pendingipgateway = 10.8.55.249
pendingipnetmask = 255.255.255.0
   Commands:
cd
set
show
-> set pending<values>
-> set commitpending=true
-> cd /CMM/network/CMM1         (repeat the above set/show commands)
-> cd /CMM/network/MASTERCMM    (repeat the above set/show commands)

4. To set local Secure-Shell (SSH) login to be enabled or disabled:

NOTE: This may change in a future firmware release to allow this setting to be copied from Active to Standby, as noted in the current SB8000 Product Notes document 819-5651:
http://docs.sun.com/app/docs/coll/blade8000

The default is 'enabled'. Use the following to disable SSH access:

On Web, click on "CMM" on left side list; then click "Configuration" tab and "System Management Access" sub-tab, and "SSH Server" sub-tab. Change the setting for "SSH Server" from "Enabled" to "Disabled". Refresh the page, then select from the same dropdown - "Restart SSH Server".

On SSH/Serial Port CLI:

-> set /CMM/services/ssh state=disabled
-> set /CMM/services/ssh restart_sshd_action=true

Note, if done from an active ssh session, after the second command the current session will be forcibly logged out immediately.

Use the same procedure except for using "Enabled" on web or "state=enabled" on CLI for enabling SSH from a disabled state.

5. To set current CMM session inactivity timeout:

On Web, click on "CMM" on left side list; then click "System Information" tab and "Session Time-out" sub-tab. Select an inactivity time-out for this session. If your session is inactive for the selected time, you will be logged out automatically. This setting is not saved and will only apply to the current session; any new sessions will reset to the default time-out of 15 minutes.

This setting only applies to Web sessions; it does not apply to SSH or Serial port CLI sessions.
