This chapter contains information on ILOM properties in the Sun Netra T5220 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 displaying the host server console output buffer.
The console buffer can contain up to 1 Mbyte of information. If ILOM senses a host server reset, it writes boot information and initialization data into the console buffer until ILOM is notified by the server that the Solaris OS is up and running.
Note - You must have Administrator level user permission to use this command. |
-> set /SP/console/history property=option[...] -> show /SP/console/history |
line_count – This option accepts a value within the range of 1 to 2048 lines. Specify "" for an unlimited number of lines. The default is all lines.
pause_count – This option accepts a value of 1 to any valid integer or "" for infinite number of lines. The default is not to pause.
If you type the show /SP/console/history command without having set any arguments with the set command, ILOM displays all lines of the console log, starting from the end.
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 enabled, 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 nonvolatile 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.
-> set /SP/policy HOST_LAST_POWER_STATE=enabled |
enabled – When power is restored, returns the server to the state it was in before the power was removed.
disabled – Keeps the server off when power is applied (the default).
If you enable HOST_LAST_POWER_STATE, you should also configure /SP/policy HOST_POWER_ON_DELAY. For further information, see Disable or Re-Enable Power-On Delay (CLI) .
Use /SP/policy HOST_AUTO_POWER_ON to power on the host automatically when the service processor has been booted. If this policy is set to enabled, the service processor sets HOST_LAST_POWER_STATE to disabled.
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 power on helps minimize current surges on the main power source. This power-on delay is important when multiple servers in racks power on after a power outage.
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, use the following procedure.
-> 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 |
