Installing the Solaris 9 OS From a Flash Archive Dynamically

My previous tech tip, Installing the Solaris OS From the Flash Archive On a Tape, discussed installing the Solaris Operating System from a tape archive.  In that case, the server has to be booted from a installation CD or DVD and the server is not available for use during the installation.

In this tech tip, I'd like to show how to install a Solaris flash archive onto a server dynamically. Using this method, the server is available all the time during the installation.

In the following example, I used the Solaris Live Upgrade command line.

The server was running the Solaris 8 OS, and I wanted to use Solaris Live Upgrade software to install the Solaris 9 OS onto a spare disk.  Instead of cloning the Solaris 8 OS onto a spare disk and using Solaris Live Upgrade software to upgrade to the Solaris 9 OS, I used a Solaris 9 flash archive on the local disk. The archive includes other third-party software and configurations.

The server I used in this example was a Sun Fire V440 Server with four 72-Gbyte internal disks. The Solaris 8 OS was installed on the first disk, with the following layout:

# df -k

Filesystem          kbytes    used   avail capacity  Mounted on
                      /dev/dsk/c9t0d0s0   482775  123810  310688    29%    /
                      /dev/dsk/c9t0d0s1  1490047 1206654  223792    85%    /usr
                      /proc                    0       0       0     0%    /proc
                      mnttab                   0       0       0     0%    /etc/mnttab
                      fd                       0       0       0     0%    /dev/fd
                      /dev/dsk/c9t0d0s3  9079661 7856344 1132521    88%    /var
                      swap               30179160     24 30179136    1%    /var/run
                      /dev/dsk/c9t0d0s6  30257446 19623302 10331570 66%    /opt

I wanted to upgrade the fourth internal disk to the Solaris 9 9/04 OS, so the first thing I needed to do was to update the current OS to the latest cluster patch level.  Doing this makes things much easier; for example, there are minimum patch and package requirements for the Solaris Live Upgrade software. Check the SunSolve web site for the latest cluster patch.

Also, you have to upgrade two Solaris Live Upgrade packages (SUNWlur and SUNWluu) from the Solaris 8 OS to the Solaris 9 OS before the upgrade. After doing that, you are ready to go.

First, I named the current Solaris 8 boot environment s8os:

# lucreate -c s8os

# lustatus

Boot Environment       Is       Active Active    Can    Copy
                      Name                   Complete Now    On Reboot Delete Status
                      ---------------------- -------- ------ --------- ------ ------
                      s8os                   yes      yes    yes       no     -

Next, from a similar server, I got a Solaris 9 flash archive I created named S9arch.flar and put it under /opt on the local server:

# cd /opt
# ls -al

total 31364348
                      drwxr-xr-x  14 root  sys        512 Jan  2 10:17 .

Then, I wanted to install the Solaris 9 OS onto the fourth internal disk.  The following command shows all the disks:

# format

                      Specify disk (enter its number):

So I created a new boot environment without actually copying the current OS over to it:

# lucreate -s - -m /:/dev/dsk/c9t3d0s0:ufs -m

/usr:/dev/dsk/c9t3d0s3:ufs -m /var:/dev/dsk/c9t3d0s4:ufs -m
                      /opt:/dev/dsk/c9t3d0s1:ufs  -m -:/dev/dsk/c9t3d0s5:swap -n
                      4thdisk

The outcome looked similar to this:

This process didn't take very long, because it was just creating all the file systems on the disk.  After it was done, the following command showed that the new boot environment was not completed yet:

# lustatus

                      Name                   Complete Now    On Reboot Delete Status
                      ---------------------- -------- ------ --------- ------ ------

                      4thdisk                no       no     no        yes    -

To complete the full installation using the Solaris 9 archive, I ensured that I put a Solaris 9 installation CD or DVD into the local server's CD-ROM drive, and then I ran this command:

# luupgrade -f -n 4thdisk -s  /cdrom/sol_9_904_sparc/s0 -a /opt/S9arch.flar

The outcome of the command looked similar to this:

Validating the contents of the media </cdrom/sol_9_904_sparc/s0>.
                      The media is a standard Solaris media.

After it completed, I used the following commands to check things:

The new boot environment was completely installed from the Solaris 9 flash archive, and it was active upon the next reboot.
