This chapter contains information on ILOM properties on the Sun Netra T5440 server that augment the array of properties that are common to ILOM on other platforms. In particular, this chapter covers properties in the /SP namespace. This chapter consists of:
This section describes ILOM features that enable you to store information (for purposes such as inventory control or site resource management) on the SP and FRU PROMs.
This section describes how to set service processor settings back to the factory defaults.
To Reset the Service Processor Settings to Factory Default Values Using the CLI
To Reset the Service Processor Settings to Factory Defaults Using the Web Interface
To Reset the Service Processor Settings to Factory Default Values Using the CLI |
Use the reset_to_defaults property to set all ILOM configuration properties back to their factory default values. The all option sets the ILOM configuration and all user information back to the factory default values.
This section describes creating new character combinations for use as escape characters.
Use the /SP/console escapechars property to change the escape character sequence to switch from a system console session back to ILOM.
-> set /SP/console escapechars=x. |
where xx are any printable characters.
The sequence is limited to two characters. The second character is always . (Period). The default value is #. (Hash-Period). The sequence can be customized.
Note - Changing the escape character does not take effect in a currently active console session. |
This section describes managing configuration system policies using ILOM.
The /SP/policy BACKUP_USER_DATA property specifies whether the local user database on ILOM (that is, user, password, and permission information) should be backed up. When this property is set to enable, this data is backed up on the removable system configuration card (SCC PROM) on the system.
Use the /SP/policy HOST_LAST_POWER_STATE property to control the behavior of the server after an unexpected power outage. When external power is restored, the ILOM service processor starts to run automatically. Normally, the host power is not turned on until you use ILOM to turn it on.
ILOM records the current power state of the server in non-volatile storage. If the HOST_LAST_POWER_STATE policy is enabled, ILOM can restore the host to the previous power state. This policy is useful in the event of a power failure, or if you physically move the server to a different location.
For example, if the host server is running when power is lost and the /SP/policy HOST_LAST_POWER_STATE property is set to disabled, the host server remains off when power is restored. If the /SP/policy HOST_LAST_POWER_STATE property is set to enabled, the host server restarts when the power is restored.
At the -> prompt, type the following command:
-> set /SP/policy HOST_LAST_POWER_STATE=enabled |
where the value for this property can be one of the following:
enabled – When power is restored, returns the server to the state it was in before the power was removed.
If you enable this property, you must configure /SP/policy HOST_POWER_ON_DELAY as well. For further information, see To Disable or Re-Enable Power On Delay Using the CLI
Use the /SP/policy HOST_POWER_ON_DELAY property to cause the server to wait for a short time before powering on automatically. The delay is a random interval of one to five seconds. Delaying the server poweron helps minimize current surges on the main power source. This poweron delay is important when multiple servers in racks power on after a power outage.
This property takes effect only if /SP/policy HOST_LAST_POWER_STATE is set to enabled.
This section describes using ILOM to view the server’s power metrics. Topics include:
-> show /SYS/VPS |
-> show /SYS/VPS /SYS/VPS Targets: Properties: type = Power Unit class = Threshold Sensor value = 306.800 Watts upper_nonrecov_threshold = 1451.40 Watts upper_critical_threshold = 1433.70 Watts upper_noncritical_threshold = 1298.00 Watts lower_noncritical_threshold = N/A lower_critical_threshold = N/A lower_nonrecov_threshold = N/A Commands: cd show |
This section describes managing network access to the SP using ILOM.
To display the IP address of the DHCP server that provided the dynamic IP address requested by the service processor, view the dhcp_server_ip property. To see the dhcp_server_ip property, do the following:
-> show /SP/network |
-> show /SP/network /SP/network Targets: Properties: commitpending = (Cannot show property) dhcp_server_ip = 10.8.31.5 ipaddress = 10.8.31.188 ipdiscovery = dhcp ipgateway = 10.8.31.248 ipnetmask = 255.255.252.0 macaddress = 00:14:4F:7E:83:4F pendingipaddress = 10.8.31.188 pendingipdiscovery = dhcp pendingipgateway = 10.8.31.248 pendingipnetmask = 255.255.252.0 state = enabled Commands: cd set show |
Use the set /SP/services/ssh generate_new_key_type command to change the type of Secure Shell (SSH) host keys generated on your server. After changing the type, you must use the set /SP/services/ssh generate_new_key_action command to generate a new set of keys of the new type.
Use the set /SP/services/ssh generate_new_key_action command to generate a new set of Secure Shell (SSH) host keys.
Use the set /SP/services/ssh restart_sshd_action command to restart the SSH server after you have generated new host keys using the set /SP/services/ssh generate_new_key_action command. This reloads the keys into the server’s dedicated data structure in memory.
Use the /SP/services/ssh state property with the set command to enable or disable the SSH service. If the SSH service has been disabled, you can re-enable it through the Serial Management (SER MGT) port or the ILOM web interface.
Log into the ILOM web interface as Administrator (root) to open the web interface.
Click Generate RSA Key or Click Generate DSA Key to generate a new key type and a new key.
If you have generated a new key, you must restart the SSH server for the new key to take effect.
Note - When the SSH server is restarted or disabled, any CLI sessions running over SSH will be terminated immediately. |
