Custom JumpStart Environment Variables
You can use environment variables in your begin and finish scripts. For example,
a begin script might extract the disk size, SI_DISKSIZES, and install or not
install particular packages on a system, based on the actual disk size the
script extracts.
Information that is gathered about a system is stored in these environment variables,
which are generally set or not, depending on the rule keywords and values
you use in the rules file.
For example, information about which operating system is already installed on a system
is only available in SI_INSTALLED after the installed keyword is used.
Table 8-9 describes these variables and their values.
Table 8-9 Installation Environment Variables
Environment Variable |
Value |
|---|
SI_ARCH |
The hardware architecture of the install
client. The SI_ARCH variable is set when the arch keyword is used in
the rules file. |
SI_BEGIN |
The name of the begin script, if one is used. |
SI_CLASS |
The
name of the profile that is used to install the install client. |
SI_DISKLIST |
A
comma-separated list of disk names on the install client. The SI_DISKLIST variable
is set when the disksize keyword is used and matched in the rules
file. The SI_DISKLIST and SI_NUMDISKS variables are used to determine the physical
disk to use for the rootdisk. rootdisk is described in How the System's Root Disk Is Determined. |
SI_DISKSIZES |
A comma-separated list of
disk sizes on the install client. The SI_DISKSIZES variable is set when
the disksize keyword is used and matched in the rules file. |
SI_DOMAINNAME |
The domain name.
The SI_DOMAINNAME variable is set when the dommainname keyword is used and matched
in the rules file. |
SI_FINISH |
The name of the finish script, if one is
used. |
SI_HOSTADDRESS |
The install client's IP address. |
SI_HOSTNAME |
The install client's host name. The SI_HOSTNAME variable is
set when the hostname keyword is used and matched in the rules file. |
SI_INSTALLED |
The
device name of a disk with a specific operating system on the
disk, for example, Solaris, SunOS, or System V. The SI_INSTALLED variable is set when
the installed keyword is used and matched in the rules file. SI_INST_OS and
SI_INST_VER are used to determine the value of SI_INSTALLED. |
SI_INST_OS |
The name of the
operating system. SI_INST_OS and SI_INST_VER are used to determine the value of
SI_INSTALLED. |
SI_INST_VER |
The version of the operating system. SI_INST_OS and SI_INST_VER are used to
determine the value of SI_INSTALLED. |
SI_KARCH |
The install client's kernel architecture. The SI_KARCH variable is
set when the karch keyword is used and matched in the rules
file. |
SI_MEMSIZE |
The amount of physical memory on the install client. The SI_MEMSIZE variable is
set when the memsize keyword is used and matched in the rules file. |
SI_MODEL |
The
install client's model name. The SI_MODEL variable is set when the model keyword
is used and matched in the rules file. |
SI_NETWORK |
The install client's network number.
The SI_NETWORK variable is set when the network keyword is used and matched
in the rules file. |
SI_NUMDISKS |
The number of disks on an install client. The SI_NUMDISKS
variable is set when the disksize keyword is used and matched in the rules
file. The SI_NUMDISKS and SI_DISKLIST variables are used to determine the physical
disk to use for the rootdisk. rootdisk is described in How the System's Root Disk Is Determined. |
SI_OSNAME |
The operating
system release on the Solaris software image. For example, you can use the
SI_OSNAME variable in a script if you are installing the Solaris software on
systems that are based on the version of the operating system on the
Solaris Operating System DVD or the Solaris Software - 1 CD image. |
SI_ROOTDISK |
The
device name of the disk that is represented by the logical name
rootdisk. The SI_ROOTDISK variable is set when the disksize or the installed
keyword is set to rootdisk in the rules file. The SI_ROOTDISK
variable sets the device to boot from during the installation.
Note - You
cannot set the place of installation by using the probe keyword “rootdisk”
in the rules file. For information on the "rootdisk" variable that is
set in a JumpStart profile, see How the System's Root Disk Is Determined.
|
SI_ROOTDISKSIZE |
The size of the disk that
is represented by the logical name rootdisk. The SI_ROOTDISKSIZE variable is set
when the disksize or the installed keyword is set to rootdisk in
the rules file. |
SI_TOTALDISK |
The total amount of disk space on the install client.
The SI_TOTALDISK variable is set when the totaldisk keyword is used and matched
in the rules file. |
