[geeks] Solaris 10 u9 live-upgrade mini-howto

[Phil Stracchino]

The results of some research and trial-and-error:  Mini-howto on how to 
live-upgrade to Solaris 10 u9, on ZFS, from a previous version that 
lacks the new autoregistration feature, opting out of autoregistration 
in the event that you do not have an existing autoregistration file or 
don't wish to autoregister.


# mkdir /mnt/iso
# lofiadm -a /.../sol-10-u9-ga-x86-dvd.iso
# mount -F hsfs /dev/lofi/1 /mnt/iso
# /mnt/iso/Solaris_10/Tools/Installers/liveupgrade20
# lucreate -n s10_u9_amd64
# echo "auto_reg=disable" > /tmp/sysidcfg
# luupgrade -u -n s10_u9_amd64 -s /mnt/iso -k /tmp/sysidcfg

[ ...wait about 20-30 minutes... ]

# zfs set mountpoint=/a rpool/ROOT/s10_u9_amd64
# zfs mount rpool/ROOT/s10_u9_amd64
# less /a/var/sadm/system/data/upgrade_cleanup

[ do whatever is needed, which in my case amounted to undoing 
replacement of openSSH-5.6p1 with Sun SSH 1.5 and re-adding my changes 
to /etc/init.d/sysetup to ifconfig bge1 ]

# less /a/var/sadm/system/data/upgrade_failed_pkgadds (if applicable)
# zfs unmount rpool/ROOT/s10_u9_amd64
# zfs set mountpoint=/ rpool/ROOT/s10_u9_amd64

# luactivate s10_u9_amd64
# init 6

You'll probably have some post-reboot cleanup to do if you're using 
non-Sun packages or applications.  For instance, in my case, mysqld and 
OpenFire (a jabberd) failed to start on the first try and had to be 
manually started; I had to replumb bge1 (I can't set it up at the 
sysidconfig phase because sysidconfig doesn't support point-to-point 
interfaces); I had to zlogin -C to my nameserver zone to clear 
sysidtool-net, which hadn't completed cleanly and turned out to have 
stuck at "What kind of terminal", preventing 30 services from starting; 
and I had to reload my property changes to 
svc:/network/dns/server:default in the nameserver zone.
