Upgrading VxFS using Live Upgrade

Solaris Live Upgrade for VxFS provides an ability to upgrade VxFS on an alternate disk while the primary disk is live and running. The pkgadd used to add a package to a Solaris installation has a -R option which the administrators can specify in order to be able to Live Upgrade VxFS.

The advantages of using Live Upgrade are:

• Less system downtime.
• One reboot will bring the system up and running on the alternate disk.
• You can revert to the pervious OS version at any time.

Prerequisites

• Verify that the Solaris Live Upgrade is complete and the alternate disk has a Solaris OS. This can be done using the Solaris Live Upgrade tool shipped with Sun Microsystems Solaris disc.

  See Sun Microsystems documentation.

• If VxVM is present on the primary, it must be upgraded to the alternate disk. The VxFS and VxVM versions must be compatible after the upgrade.

Begining the Live Upgrade

 To begin the Live Upgrade

1. Mount the alternate disk in a directory on the primary disk. For example,

   # mount -F ufs /dev/dsk/c1t0d0s0 /altroot5.10

where c1t0d0s0 is the alternate disk.

where /altroot5.10 is the mount point on the primary disk.

2. Remove the existing VxFS package from the alternate disk. For example,

   # pkgrm -R /altroot5.10 VRTSvxfs

3. Add the VxFS 5.0 package to the alternate disk. For example,

   # pkgadd -R /altroot5.10 VRTSvxfs

   # pkgadd -R /altroot5.10 VRTSfsmnd

   # pkgadd -R /altroot5.10 VRTSfssdk

   # pkgadd -R /altroot5.10 VRTSfsdoc

   # pkgadd -R /altroot5.10 VRTSfsman

   # pkgadd -R /altroot5.10 VRTSfsprv

   # pkgadd -R /altroot5.10 VRTSfscat

   # pkgadd -R /altroot5.10 VRTSap

   # pkgadd -R /altroot5.10 VRTStep

   # pkgadd -R /altroot5.10 VRTSfspro

   # pkgadd -R /altroot5.10 VRTSob

4. Shut down the machine using shutdown or init 6 to reboot the machine on the alternate root disk.

   # init 6

     Note   Don't use the reboot command to reboot the machine on an alternate root disk. If the alternate root disk has a problem rebooting or any upgrade issue, reboot the machine from the older disk.

Verifying the upgrade

 To verify the upgrade

• Verify that VxFS has been upgraded and are the new versions. Check a few of the packages. For examle,

  # pkginfo -l VRTSvxfs

  # pkginfo -l VRTSfsmnd

  # pkginfo -l VRTSfssdk
