Way that works with Solaris Cluster and immutable zones

Problem was that some steps of updating (indexing man pages etc) could not be done in the immutable zone after solaris update. So one boot -w is necessary to come up in cluster.

Move all RGs from node first

# clrg evacuate -n $(hostname) +

Update Solaris

# pkg update --be-name $(pkg info -r system/kernel | nawk '/Build Release:/{split($NF,release,".");}/Branch:/{split($NF,versions,".");print "Solaris_"release[2]"."versions[3]"_SRU"versions[4];}') --accept -v

# init 6

Disable zone on other node and move to self

But leave the HAStoragePlus resource online

# clrs disable zone01-zone-rs
# clrg switch -n $(hostname) zone01-rg

Attach, boot -w, detach without cluster

# zoneadm -z zone01 attach -u
# zoneadm -z zone01 boot -w
# zlogin     zone01 svcs -xv        # <- wait for all services to be ready
# zlogin     zone01 svcs -xv        # <- wait for all services to be ready
...
# zlogin     zone01 svcs -xv        # <- wait for all services to be ready
# zoneadm -z zone01 halt
# zoneadm -z zone01 detach

Enable zone in cluster

# clrs enable zone01-zone-rs

Some other things

# zoneadm -z zone01 attach -x deny-zbe-clone -z solaris-7
# clrs enable zone01-rs

# /usr/lib/brand/solaris/attach:

Brand specific options:

Usage:
         attach [-uv] [-a archive | -d directory | -z zbe]
                [-c profile.xml | dir] [-x attach-last-booted-zbe|
                        force-zbe-clone|deny-zbe-clone|destroy-orphan-zbes]

        -u      Update the software in the attached zone boot environment to
                match the sofware in the global zone boot environment.
        -v      Verbose.
        -c      Update the zone configuration with the sysconfig profile
                specified in the given file or directory.
        -a      Extract the specified archive into the zone then attach the
                active boot environment found in the archive.  The archive
                may be a zfs, cpio, or tar archive.  It may be compressed with
                gzip or bzip2.
        -d      Copy the specified directory into a new zone boot environment
                then attach the zone boot environment.
        -z      Attach the specified zone boot environment.
        -x      attach-last-booted-zbe  : Attach the last booted zone boot
                                           environment.
                force-zbe-clone         : Clone zone boot environment
                                           on attach.
                deny-zbe-clone          : Do not clone zone boot environment
                                           on attach.
                destroy-orphan-zbes     : Destroy all orphan zone boot
                                           environments. (not associated with
                                           any global BE)
