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.

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

This is easy: In the global zone [EMAIL PROTECTED] zoneadm list global labv490-01z3 labv490-01z2 labv490-01z6 labv490-01z7 labv490-01z4 labv490wsz1 labv490wsz2 labv490wsz3 labv490-01z1 [EMAIL PROTECTED] In the non-global [EMAIL PROTECTED] zoneadm list labv490-01z1 If the output form zoneadm list shows the word "global", you are in the global zone.

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 2>&1
[ $? -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".

And zonecfg(1M) states that the name 'global' is reserved.

Re: [zones-discuss] how to find global-zone from zone
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.

[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). Thanks in advance Remco ___ zones-discuss mailing list zones-discuss@opensolaris.org
