System Management Services Software

SMS software supports Sun Fire servers running the Solaris Operating Environment. SMS software is compatible with Sun Fire 15K domains that are running the Solaris operating environment. The commands provided with the SMS software can be used remotely.
SMS software enables the
platform
administrator to perform the following tasks:
-
Administrate domains by logically grouping domain configurable units (DCU) together. DCUs are system boards such as CPU and I/O boards. Domains are able to run their own operating systems and handle their own workloads.
-
Dynamically reconfigure a domain so that currently installed system boards can be logically attached to or detached from the operating system while the domain continues running in multiuser mode. A system board can be physically swapped in and out when it is not attached to a domain, even while the system continues running in multiuser mode.
-
Perform automatic dynamic reconfiguration of domains using a script.
-
Monitor and display the temperatures, currents, and voltage levels of one or more system boards or domains.
-
Monitor and control power to the components within a platform.
-
Execute diagnostic programs such as power-on self-test (POST).
In addition, SMS software:
-
Warns you of impending problems, such as high temperatures or malfunctioning power supplies.
-
Notifies you when a software error or failure has occurred.
-
Monitors a dual SC configuration for single points of failure and performs an automatic failover from the main SC to the spare SC, depending on the failure condition detected.
-
Automatically reboots a domain after a system software failure such as a panic.
-
Keeps logs of interactions between the SC environment and the domains.
-
Provides support for the Sun Fire 15K dual grid power option.
SMS software enables the
domain
administrator to perform the following tasks:
-
Administrate domains by logically grouping domain configurable units (DCU) together. DCUs are system boards such as CPU and I/O boards. Domains are able to run their own operating systems and handle their own workloads.
-
Boot domains for which the administrator has privileges.
-
Dynamically reconfigure a domain for which the administrator has privileges. Thus currently installed system boards can be logically attached to, or detached from, the operating system while the domain continues running in multiuser mode.
-
Perform automatic dynamic reconfiguration of domains using a script for which the administrator has privileges.
-
Monitor and display the temperatures, currents, and voltage levels of one or more system boards or domains for which the administrator has privileges.
-
Execute diagnostic programs such as power-on self-test (POST) for which the administrator has privileges.

-
Dynamic System Domain (DSD) configuration
-
Configured domain services
-

Hardware status monitoring, reporting and handling
-
Hardware error monitoring, reporting and handling
-
System Controller (SC) failover
-
Configurable administrative privileges
System Architecture
SMS software uses a distributed client-server architecture.
init
(1M) starts, and restarts as necessary, one process:
ssd
(1M).
ssd
is responsible for monitoring all other SMS processes and restarting them as necessary.
The Sun Fire 15K platform, the SC, and other workstations communicate over Ethernet. You perform SMS operations by entering commands on the SC console after remotely logging onto the SC from another workstation on the local area network. You must log in as a user with the appropriate platform or domain privileges if you want to perform SMS operations such as monitoring and controlling the platform.
Dual system controller boards are supported within the Sun Fire 15K platform. One board is designated as the primary or main system controller board, and the other is designated as the spare system controller board. If the main system controller fails, the failover capability automatically switches to the spare system controller.
SMS Administration Environment
Administration tasks on the Sun Fire 15K are secured by group privileges requirements. Upon installation, SMS installs the following UNIX groups to the
/etc/group
file.
-
platadmn
identifies a platform administrator.
-
platoper
identifies a platform operator.
-
platsvc
identifies a platform service.
-
dmn[
A...R
]admn
- domain [
domain_id|domain_tag
] identifies the administrator of one of the eighteen available domains.
-
dmn[
A...R
]rcfg
- domain [
domain_id|domain_tag
] identifies the configurator of one of the eighteen available domains.
Management Network
One of the system controller's main functions is to provide administration services for the Sun Fire 15K platform and its domains. The Sun Fire 15K Management Network (MAN) is a combination of hardware and software providing the network architecture by which such administration services are delivered.
The primary services provided by the Management Network include:
-
Domain consoles
-
Message logging
-
Time synchronization
-
Dynamic reconfiguration
-
Network boot and Solaris installation
-
System Controller heartbeats
Access to the Management Network is restricted to the SC and the domains in the platform. No external IP traffic should be routed across the Management Network.
