ssh as normal
or is you cannot

zlogin zonename
will give you root on the zone
Console login to a zone
zlogin -C zonename
Run a command on a zone

double check the metadevice that the file system exists on on the global zone

test mount on global zone , umount and restart zone with new volume size
Metasets
Normal metacommands will function as expected but will need to be called with –s to allow for metaset use
Eg: metastat –s <setname>
Create metaset (you can have 4 hosts)
metaset –s <setname> -a h <hostname> <hostname> <hostname> <hostname>
add disks to metaset
metaset –s <setname> -a <cXtXdX> ….
At this point normal SDS commands can be used to create volumes on the metasets
Eg: metainit –s <setname> dXXX 1 1 cXtXdX cYtYdY
Failover
Failover from one node to another is done with metoffline and metaonline
On host 1
Metaoffline –s <setname> dX
On host 2
Metaonline –s <setname> dX
Dtrace stuff
Dtrace - watch new processes and print full ags
dtrace -n 'proc:::exec-success { trace(curpsinfo->pr_psargs); }'
New command options under Sol 10
prstat -Z - show zone info
df -h - show df in more human readable form

But you know your have at least 12 internal disks in yout e450 !!!!
At the ok prompt enter the following command:
setenv disk-led-assoc 0 x ywhere:n x is an integer between 1 and 10 identifying the PCI slot number where the
lower UltraSCSI controller is installed
n y is an integer between 1 and 10 identifying the PCI slot number where the
upper UltraSCSI controller is installed
For example, if the controller cards are installed in PCI slots 5 and 7, enter the
following:
setenv disk-led-assoc 0 5 7
then reset system for changes to take effect
Sendmail - without daemon
echo "MODE=" > /etc/default/sendmail
then bounce sendmail , you wull now notice it's got to -bd in the args
now we need to alter the submit.cf , best to use the macros lest it get clobbered with a patch
perl -p -i*.bak -e 's/127.0.0.1/mailhost/g' /usr/lib/mail/cf/submit.cf
(assming mailhost is the name of your smtp server)
Compile the new submit.cf file
cd /usr/lib/mail/cf
/usr/ccs/bin/m4 ../m4/cf.m4 submit.mc > submit.cf
Copy this new submit.cf file into place
cp /usr/lib/mail/cf/submit.cf /etc/mail/submit.cf
Remember every time you apply a sendmail patch on this machine, rebuild the submit.cf file.
- caveat -
only tested on Solaris 9 ;) .... YMMV

Stoping Break on a SUN
Power-switch key method:
On Enterprise-type Suns, the power switch has four positions: off, on, diagnostic and secure. With the power switch in the secure position, the system ignores BREAKs generated by keyboard reconnect, serial terminal loss, Stop-a or a serial terminal BREAK key.
Command method:
In /etc/default/kbd, add the variable KEYBOARD_ABORT=disable then use the command kbd -i
which reads /etc/default/kbd and disables keyboard abort.
