                      Assembled 29 July 2010

How to Display a System's Host ID Number

To display the host ID number in hexadecimal format, use the hostid command.

Example 2-1 Displaying a System's Host ID Number

The following example shows sample output from the hostid command.

$ hostid
80a5d34c

How to Display a System's Product Name

The -b option to the prtconf command enables you to display a system's product name. For more information about this feature, see the prtconf(1M) man page.

To display the product name for your system, use the prtconf command with the -b option, as follows:
```
% prtconf -b
```

Example 2-2 Displaying a System's Product Name

This example shows sample output from the prtconf -b command.

$ prtconf -b
name:  SUNW,Ultra-5_10
model:  SUNW,375-0066
banner-name:  Sun Ultra 5/10 UPA/PCI (UltraSPARC-IIi 333MHz)

This example shows sample output from the prtconf -vb command.

% prtconf -vb
name:  SUNW,Sun-Fire-T200
banner-name:  Sun Fire T200
compatible: 'sun4v'
idprom:  01840014.4f7e5e84.00000000.7e5e84de.00000000.00000000.00000000.00000000
openprom model:  SUNW,4.30.4.a
openprom version: 'OBP 4.30.4.a 2010/01/06 14:56'

How to Display a System's Installed Memory

To display the amount of memory that is installed on your system, use the prtconf command.

Example 2-3 Displaying a System's Installed Memory

The following example shows sample output from the prtconf command. The grep Memory command selects output from the prtconf command to display memory information only.

$ prtconf | grep Memory
Memory size: 65408 Megabytes

How to Display the Date and Time

To display the current date and time according to your system clock, use the date command.

Example 2-4 Displaying the Date and Time

The following example shows sample output from the date command.

$ date
Mon Sep 13 17:32:59 MST 2010
$

Command Option to Identify Chip Multithreading Features

The psrinfo command has been modified to provide information about physical processors, in addition to information about virtual processors. This enhanced functionality has been added to identify chip multithreading (CMT) features. The new -p option reports the total number of physical processors that are in a system. Using the psrinfo -pv command will list all the physical processors that are in the system, as well as the virtual processors that are associated with each physical processor. The default output of the psrinfo command continues to display the virtual processor information for a system.

For more information, see the psrinfo(1M) man page.

For information about the procedures that are associated with this feature, see How to Display a System's Physical Processor Type.

How to Display a System's Physical Processor Type

Use the psrinfo -p command to display the total number of physical processors on a system.

$ psrinfo -p
1

Use the psrinfo -pv command to display information about each physical processor on a system, and the virtual processor that is associated with each physical processor.

$ psrinfo -pv
The UltraSPARC-IV physical processor has 2 virtual processors (8, 520)
The UltraSPARC-IV physical processor has 2 virtual processors (9, 521)
The UltraSPARC-IV physical processor has 2 virtual processors (10, 522)
The UltraSPARC-IV physical processor has 2 virtual processors (11, 523)
The UltraSPARC-III+ physical processor has 1 virtual processor (16)
The UltraSPARC-III+ physical processor has 1 virtual processor (17)
The UltraSPARC-III+ physical processor has 1 virtual processor (18)
The UltraSPARC-III+ physical processor has 1 virtual processor (19)

When you use the psrinfo -pv command on an x86 based system, the following output is displayed:

$ psrinfo -pv
The i386 physical processor has 2 virtual processors (0, 2)
The i386 physical processor has 2 virtual processors (1, 3)

How to Display a System's Logical Processor Type

Use the psrinfo -v command to display information about a system's processor type.
```
$ psrinfo -v
```
On an x86 based system, use the isalist command to display the virtual processor type.
```
$ isalist
```

Example 2-5 SPARC: Displaying a System's Processor Type

This example shows how to display information about a SPARC based system's processor type.

% psrinfo -v
Status of virtual processor 28 as of: 09/13/2010 14:07:47
  on-line since 04/08/2010 21:27:56.
  The sparcv9 processor operates at 1400 MHz,
        and has a sparcv9 floating point processor.
Status of virtual processor 29 as of: 09/13/2010 14:07:47
  on-line since 04/08/2010 21:27:56.
  The sparcv9 processor operates at 1400 MHz,
        and has a sparcv9 floating point processor.

Example 2-6 x86: Displaying a System's Processor Type

This example shows how to display information about an x86 based system's processor type.

$ isalist
pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86
