Help needed - trying to run commands in Guest LDoms from Control LDOM
Hi Folks,
I am used to writing scripts to get info by running commands at local zones level from their respective global zone by using zlogin <localzone> "command>" while remaining at the global zone level.
Can the same be done with Guest LDoms while remaining at the control LDOM level?
I'm really stuck here. I've created an LDOM on a SPARC T4-1 with Solaris 11.4 to run a copy of Linux for SPARC. I got the Linux ISO installed and Linux itself installed and booted OK. The only thing is is that there's no networking available in the Linux guest.
This question is basically the... (7 Replies)

Hi,
There is LDOM Guest where I need to expand /u02 file systems on it.
It is residing on a Solaris 11 Hypervisor (Primary Domain).
The storage is expanded on vdisk presented to Hypervisor.

Hi all,
New to this forum.
I have just been reading through a historical thread about some issues with IPMP.
Some tips from "Peasant" where very useful. Please see below

For VDS, use one VDS - one guest LDOM, don't put everything in primary-vds.... (9 Replies)
Im looking for the commands that can be executed to fetch the OS Version of the VMs running on the below Hypervisors.

We are having a discussion on what order LDOMS and control domains should be booted.
I think it should be LDOMS first then Control. Can anyone tell me why I am wrong or why I am right.
Thanks,

Solaris for Sparc 11.1 with the latest patches. Created a Guest LDOM with two vnet's net0 and net1, installed a guest whole root, ip exclusive zone that I want to be able to utilize DHCP. I have been able to create the zone but unable to get it to boot because I am unable to assign an anet to it.... (4 Replies)
Hi Everyone,
one question is it possible to migrate a physical standalone Solaris 8 or 9 OS to Guest Domain (LDOMs).
If yes, can someone please provide steps to migrate these OS to LDOMs.
Thanks,

zlogin(1) User Commands zlogin(1)NAME
zlogin - enter a zone
SYNOPSIS
zlogin [-CE] [-e c] [-l username] zonename
zlogin [-ES] [-e c] [-l username] zonename utility [argument...]
DESCRIPTION
The zlogin utility is used by the administrator to enter an operating system zone. Only a superuser operating in the global system zone can
use this utility.
zlogin operates in one of three modes:
Interactive Mode
If no utility argument is given and the stdin file descriptor for the zlogin process is a tty device, zlogin operates in interactive
mode. In this mode, zlogin creates a new pseudo terminal for use within the login session. Programs requiring a tty device, for exam-
ple, vi(1), work properly in this mode. In this mode, zlogin invokes login(1) to provide a suitable login session.
Non-Interactive Mode
If a utility is specified, zlogin operates in non-interactive mode. This mode can be useful for script authors since stdin, stdout, and
stderr are preserved and the exit status of utility is returned upon termination. In this mode, zlogin invokes su(1M) in order to set
up the user's environment and to provide a login environment.
Console Mode
If the -C option is specified, the user is connected to the zone console device and zlogin operates in console mode. The zone console
is available once the zone is in the installed state. Connections to the console are persistent across reboot of the zone.
OPTIONS
The following options are supported:
-C Connects to the zone console.
-e c Specifies a different escape character, c, for the key sequence used to access extended functions and to disconnect from
the login. The default escape character is the tilde (~).
-E Disables the ability to access extended functions or to disconnect from the login by using the escape sequence character.
-l username Specifies a different username for the zone login. If you do not use this option, the zone username used is "root". This
option is invalid if the -C option is specified.
-S "Safe" login mode. zlogin does minimal processing and does not invoke login(1) or su(1M). The -S option can not be used if
a username is specified through the -l option, and cannot be used with console logins. This mode should only be used to
recover a damaged zone when other forms of login have become impossible.
Escape Sequences
Lines that you type that start with the tilde character (~) are "escape sequences". The escape character can be changed using the -e
option.
~. Disconnects from the zone. This is not the same as a logout, because the local host breaks the connection with no warning to the
zone's end.
SECURITY
Once a process has been placed in a zone other than the global zone, the process cannot change zone again, nor can any of its children.
OPERANDS
The following operands are supported:
zonename The name of the zone to be entered.
utility The utility to be run in the specified zone.
argument... Arguments passed to the utility.
EXIT STATUS
In interactive and non-interactive modes, the zlogin utility exits when the command or shell in the non-global zone exits. In non-interac-
tive mode, the exit status of the remote program is returned as the exit status of zlogin. In interactive mode and console login mode, the
exit status is not returned. zlogin returns a 0 exit status as long as no connection-related error occurred.
In all modes, in the event that a connection to the zone cannot be established, the connection fails unexpectedly, or the user is lacking
sufficient privilege to perform the requested operation, zlogin exits with status 1.
To summarize, the following exit values are returned:
0 Successful entry.
1 Permission denied, or failure to enter the zone.
Any Return code from utility, or from su(1M) if operating in non-interactive mode.
