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

<syntaxhighlight lang=bash>

1. clrg evacuate -n $(hostname) +

</source>

Update Solaris

<syntaxhighlight lang=bash>

1. 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

1. init 6

</source>

Disable zone on other node and move to self

But leave the HAStoragePlus resource online <syntaxhighlight lang=bash>

1. clrs disable zone01-zone-rs
2. clrg switch -n $(hostname) zone01-rg

</source>

Attach, boot -w, detach without cluster

<syntaxhighlight lang=bash>

1. zoneadm -z zone01 attach -u
2. zoneadm -z zone01 boot -w
3. zlogin zone01 svcs -xv # <- wait for all services to be ready
4. zlogin zone01 svcs -xv # <- wait for all services to be ready

...

1. zlogin zone01 svcs -xv # <- wait for all services to be ready
2. zoneadm -z zone01 halt
3. zoneadm -z zone01 detach

</source>

Enable zone in cluster

<syntaxhighlight lang=bash>

1. clrs enable zone01-zone-rs

</source>

Some other things

<syntaxhighlight lang=bash>

1. zoneadm -z zone01 attach -x deny-zbe-clone -z solaris-7
2. clrs enable zone01-rs

</source>

<syntaxhighlight lang=bash>

1. /usr/lib/brand/solaris/attach:

Brand specific options: brand-specific usage: Usage:

        attach [-uv] [-a archive | -d directory | -z 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
