Upgrading VxVM 3.1 on HP-UX 11.0 to VxVM 3.5 on HP-UX
11i
The upgrade procedure allows you to retain your existing HP-UX 11.0 VxVM
configuration. After upgrading, you can resume using VxVM on the same host with an
upgraded operating system without running the vxinstall procedure.
Note The following procedure describes how to migrate VxVM disk groups between
different versions of the HP-UX operating System and assumes that the VxVM disk
groups being migrated are already using VxVM 3.1, not VxVM 3.0.
If you need to upgradeVxVM 3.0 diskgroups toVxVM 3.1 diskgroups, refer to Installing
Veritas Volume Manager for HP-UX on HP-UX 11i. The manual is available at the HP
documentation web site: http://www.docs.hp.com. Search using the phrase “VERITAS
Volume Manager”.
Migration Procedure
1. Print the current VxVM configuration into a file, and then copy the file to a system
that is not the VxVM server being upgraded. Use the following command to print the
configuration to a file:
# vxprint -mh > /file1
2. Copy the current license-key files to a system that is not the VxVM server being
upgraded. The VERITAS license-keyfiles are in the/etc/vx/elm directory and have
a .lic extension.
3. Print the current license-key configuration into a file, then copy the file to a system
that is not the VxVM server being upgraded. Use the following command to print the
configuration to a file:
# vxlicense -p > /vxlicense1.out
4. Unmount all file systems mounted on VxVM volumes using the umount(1M)
command or the Volume Manager Storage Administrator (VMSA) graphical user
interface (GUI). For example:
# umount /vxvm_vol1
# umount /vxvm_vol2
5. Copy the lines in /etc/fstab that mount the VxVM file systems into a file on a
system other than the VxVM server that is being upgraded.
