[zones-discuss] how to find global-zone from zone
Hi, I was wondering if it's possible to find out to which global zone a zone is related. (And not from Globalzone point of view!) It might happen (as a sysadmin) that you login to a zone but you need to perform maintenance in the global zone (i.e. Veritas VM -stuff).

Remco, There is no command to display the Global zone of a non-global zone but there are a few tricks that I have heard of. One is to create a file in the zone path of each zone and then read it from the non-global On the Global touch /zone_path/root/etc/global.hostname On the non ls -l /etc/global* -JOhn Remco Fugers wrote: Hi, I was wondering if it's possible to find out to which global zone a zone is related.

Re: [zones-discuss] how to find global-zone from zone
In a related, but similar situation. How does one know that they are actually in a non-global zone vs a global zone? (Using a committed interface). zonename(1). And zonecfg(1M) states that the name 'global' is reserved.

Re: [zones-discuss] how to find global-zone from zone
Hi,
we implemented a cron-job in the global zone to run the following srcipt:
#!/bin/ksh
PATH=$PATH:/usr/sbin:/usr/bin
OSVERSION=`uname -r | awk -F. '{print $2}'`
if [ ${OSVERSION} -gt 9 ]; then
zonename | grep global /dev/null 21
[ $? -ne 0 ] exit 0
for i in `zoneadm list -v| awk '{print $4}' | grep -v ^/$ | grep ^/`
do
echo `hostname` $i/root/etc/globalzone
done
fi
So you have just to do a cat /etc/globalzone.

Just use zonename; if it comes back global, you're in a global zone. If anything else, you're not. Attribute is Evolving, is that better than looking for pids? And maybe one day there will be pid 0, 1, 2, 3 in a non-global zone. CT ___ zones-discuss mailing list zones-discuss@opensolaris.org

Re: [zones-discuss] zonename
This question has been asked before. This is the trick we use: Since the zone command /usr/sbin/zoneadm list -vi does not display the name of the global zone when logged on to a local zone, we added to the global zone OS filesystem in "/usr/bin" a script/command called "zone-global-name". This script has the global zone name hard coded and echoes its name. e.g. #!/bin/sh echo "global zone name" Now every time we build a new local zone this command is copied or shared with the local zone depending on the type of zone created. This installs a command that will always show you the name of the global zone when you are on logged on to the local zone. Kind of a hack, but it works for us.

Re: [zones-discuss] how to find global-zone from zone
Since this seems to be a common question that has shown up on this list from time to time, I have added our method to our Solaris Zone RunBook which is free and posted it at: http://www.logiqwest.com/dataCenter/Demos/RunBooks/Zones/listingGlobal.html Hope this helps till Sun finally puts a real command in the OS.
