Solaris 11 global zone and non-global zone pathing order

Hi Guys,

hope you can help me in a very trivial suggestion about updation the last SRU in a global and non-global zone envirnoment.

Which ist the best and official way to go:

1

shutdown all non-global zones and detach

update global zone

reboot

attach non-global zones -u/-U

2

update global zone while running non-global zones

shutdown all non-global zones and detach

reboot

attach non-global zones -u/-U

second option is a bit easier for me to handle because I can limit the downtime but not sure if it is right to do so.

Best regards,

Oliver
