How to migrate solaris 10 global zone into solaris 11 ? P2V

In upcoming days,definitely you need to migrate the solaris 10 physical servers as a local zone in solaris 11 global zone if you want to continue to use solaris 10 operating system.These kind of situation rasie  due to application incompatibility with high version of operating systems.So you may need to stick with older version of operating system in a order to support the legacy applications. So oracle provides an option to run solaris 10 on solaris 11 physical servers as local zone.Oracle Solaris 11 provides the complete virtualization on networking part and ultimate package administration which was missing on solaris 10. As you know  that solaris 11 comes with image packaging system(IPS) and its also supports the legacy packaging system SVR4.

In the previous article ,we have seen that  how to install the fresh solaris 10 localzone installation on solaris 11 global zone.But here we will see how to convert the existing solaris 10 physical servers as local zone on solaris 11 global zone.We can also call this operation as physical to virtual (p2v).

Solaris 10 – P2V on Solaris 11 Global zone

Prerequisites:

  1. Solaris 10 physical server must be running with solaris 10 10/11 update.
  2. Solaris 11 global zone must have minimum 7Gb of free space for solaris 10 zone installation.(size may vary according to your solaris 10 physical machine root filesystem)

1.Login to solaris 10 physical machine and halt if you have any local zones on it. (zones can’t be migrated to solaris 11 global zone directly).You need to follow V2V method for zone’s migration.

bash-3.00# zoneadm list -cv
  ID NAME             STATUS     PATH                           BRAND    IP
   0 global           running    /                              native   shared
   1 u1               running    /export/zones/u1               native   shared
bash-3.00# zoneadm -z u1 halt
bash-3.00# zoneadm list -cv
  ID NAME             STATUS     PATH                           BRAND    IP
   0 global           running    /                              native   shared
   - u1               installed  /export/zones/u1               native   shared
bash-3.00#

2.Create the solaris 10 global zone flar . “-x” option is used to exclude other filesystem than root.

bash-3.00# flarcreate -S -n uasol10 -x /hgfs -x /P2VSOL10 -x /export/zones/u1 -L cpio /P2VSOL10/uasol10.flar
Archive format requested is cpio
This archiver format is NOT VALID for flash installation of ZFS root pool.
This format is useful for installing the system image into a zone.
Reissue command without -L option to produce an archive for root pool install.

bash-3.00#

3.Verify the flar image .

bash-3.00# cd /P2VSOL10
bash-3.00# ls -lrt
total 584028
-rwx------   1 root     root     598043988 Mar 28 01:50 uasol10.flar
bash-3.00#

4.Login to solaris 11 global zone and install the brand package which has explained in this article.(only Step no:4)

5.Copy the flar image which we have created on solaris 10 physical machine to solaris 11 global zone.If possible ,you can also mount the flar image directory as NFS.Here i have manually copied  it on /oraz1 location.

6.Create the zone’s configuration for solaris 10.I took the host id from the solaris 10 physical machine.

root@UAAIS:~# zonecfg -z p2vsol10
Use 'create' to begin configuring a new zone.
zonecfg:p2vsol10> create -t SYSsolaris10
zonecfg:p2vsol10> set zonepath=/oraz1/p2vsol10
zonecfg:p2vsol10> select anet linkname=net0
zonecfg:p2vsol10:anet> set allowed-address=192.168.2.112/24
zonecfg:p2vsol10:anet> set configure-allowed-address=true
zonecfg:p2vsol10:anet> end
zonecfg:p2vsol10> set hostid=11302069
zonecfg:p2vsol10> verify
zonecfg:p2vsol10> commit
zonecfg:p2vsol10> exit
root@UAAIS:~# zoneadm list -cv
  ID NAME             STATUS     PATH                           BRAND    IP
   0 global           running    /                              solaris  shared
   3 uasol10z1        running    /oraz1/sol10z1/uasol10z1       solaris10 excl
   - uaz1             installed  /export/zones/uaz1             solaris  excl
   - uaz2             installed  /export/zones/uaz2             solaris  excl
   - p2vsol10         configured /oraz1/p2vsol10                solaris10 excl
root@UAAIS:~#

7.Install the zone using the flar which we have created from the solaris 10 physical machine.

root@UAAIS:/oraz1# zoneadm -z p2vsol10 install -a /oraz1/uasol10.flar -u
The following ZFS file system(s) have been created:
    oraz1/p2vsol10

   Postprocess: The following zones in this image will be unusable: u1
   Postprocess: These zonepaths will be extracted but will not be used:

        Result: Installation completed successfully.

  ID NAME             STATUS     PATH                           BRAND    IP
   0 global           running    /                              solaris  shared
   - uaz1             installed  /export/zones/uaz1             solaris  excl
   - uaz2             installed  /export/zones/uaz2             solaris  excl
   - uasol10z1        installed  /oraz1/sol10z1/uasol10z1       solaris10 excl
   - p2vsol10         installed  /oraz1/p2vsol10                solaris10 excl
root@UAAIS:/oraz1#

Here you can see solaris 10 zone has been successfully installed using the flar image.

8.Boot the local zone and login to the zone’s console .If there is any initial configuration is required, just complete the sysconfig wizard.

root@UAAIS:/oraz1# zoneadm -z p2vsol10 boot
root@UAAIS:/oraz1#
root@UAAIS:~# zoneadm list -cv
  ID NAME             STATUS     PATH                           BRAND    IP
   0 global           running    /                              solaris  shared
   7 p2vsol10         running    /oraz1/p2vsol10                solaris10 excl
   - uaz1             installed  /export/zones/uaz1             solaris  excl
   - uaz2             installed  /export/zones/uaz2             solaris  excl
   - uasol10z1        installed  /oraz1/sol10z1/uasol10z1       solaris10 excl
root@UAAIS:~#

9.You may get below error(couldn’t set locale correctly) if the initial configuration wizard is not completed.Login to zone’s console and complete it .

root@UAAIS:/oraz1# zlogin p2vsol10

I have forced the things and able to bring the zone to installed state.

But when i tried to boot , i got the following errors .

root@UAAIS:~# zoneadm -z  p2vsol10 boot

I  have blindly started the migration without checking the prerequisites. My solaris 10 physical servers was running on solaris 10 10/09 as it supposed to be update 11.Then i have just install the missing patches which have showing in error and created the new flar.

 

In my second attempt also failed due to insufficient disk space.Here you can see the errors.

root@UAAIS:/oraz1# zoneadm -z p2vsol10 install -a /oraz1/uasol10.flar -u

I just came to know by looking the logs generated by zoneadm command.

Hope this article will help you to make the solaris 10 physical servers as local zones on solaris 11 global zone.Please leave a comment if you have any issue on this migration.
