Memory This line displays the amount of memory conﬁgured on the system in MB and GB. If the

-m option is used, a second line will display the amount of Interleaved Memory (ILM).

This information can be obtained using

. See

pstat_getlocality(2) for information on how to calculate ILM.

Firmware This section lists the versions of ﬁrmware components that are installed on the system.

The number and type of ﬁrmware components is platform dependent. It may also indicate

if IPMI is supported.

This information can be obtained using

_SI_BMC_FW_REV,)

and sysconf(_SC_IPMI_INTERFACE)

Platform Info

This section contains the model, machine ID number and the machine serial number. The

ﬁelds are interpreted as follows:

Model: The hardware model string.

Machine ID Number:

Unique identiﬁer for each machine. Returned as an opaque string of print-

able ASCII characters. This string has the same value of all partitions in a

physical machine.

Machine Serial Number:

Not available on all classes of machines; if unavailable, will print a mes-

sage that "indicates id is not set for this machine". This string is not a

unique identiﬁer for the machine, since machines of different classes can

have the same serial number.

This information can be obtained using

confstr(_CS_MACHINE_MODEL,

_CS_MACHINE_IDENT, _CS_MACHINE_SERIAL)

OS Info This section contains general information about the version of the OS installed on the sys-

tem. The ﬁelds are interpreted as follows:

Nodename: The node name (system name by which the system is usually known in the
