Full Discussion: Solaris 11 Global zone patching having Solaris 10 branded zone
Operating Systems Solaris Solaris 11 Global zone patching having Solaris 10 branded zone Post 303012849 by Peasant on Saturday 10th of February 2018 11:33:08 PM
Old 02-11-2018
Just a small disclaimer, i never worked with solaris 10 branded zones.

But, since it's a whole root zone, upgrade of solaris 11 global zone should have minimal to no effect to such zones.
Actually, no patching should occur for solaris10 zone.

So if the solaris 11 release you are patching support solaris10 branded zones, you should be fine.

I would go with normal attach with using preview switch first -n and examine the output.

If everything goes well in preview, run the normal attach.

Also, Solaris 11 system when doing major patching will create a backup boot environment automatically, followed by patching and activation of patched environment.
After the patching finishes, a reboot should suffice.
pkg subsystem will write that on the console after patching, and you can confirm the same by issuing beadm list after patching.

Depending on the importance of the system in the zone, backup(s) should be made.
This is done using zfs archives or zoneadm command subswitches and, of course, exporting the text configuration of zone using zonecfg.


Hope that helps
Regards
Peasant.

NAME

       zcons - Zone console device driver

DESCRIPTION

       The  zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
       tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the  global
       zones.

       Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave  side is fronted
       by /dev/console and other console-related  symbolic links, which are used by applications that expect to write to the system console.

       The zcons driver is Sun Private, and may change in future releases.

FILES

       /dev/zcons/<zonename>/masterconsole

	   Global zone master side console for zone <zonename>.

       /dev/zcons/<zonename>/slaveconsole

	   Global zone slave side console for zone <zonename>.

       /dev/zconsole

	   Non-global zone console (slave side).
