Optional Configuration Steps
After the upgrade is complete, you can optionally perform the steps discussed in this section based
on the requirement, in addition to the steps discussed in “Upgrading From VxVM 5.0 on HP-UX
11i v3 to VxVM 5.1 SP1 Using Integrated VxVM 5.1 SP1 Package for HPUX 11i v3” (page 62).
To perform the optional configuration steps, complete the following procedure:
1. To encapsulate and mirror the boot disk, follow the procedures in the "Administering Disks"
chapter of the Veritas Volume Manager Administrator’s Guide.
2. To upgrade VxFS Disk Layout versions and VxVM Disk Group versions, follow the upgrade
instructions discussed in “Upgrading VxVM Disk Group Versions” (page 66).
Upgrading Disk Layout Versions
You must upgrade your older disk layout versions to make use of the extended features available
in VxFS 5.1 SP1.
For information on the new features, see the Veritas File System 5.1 SP1 Release Notes. To locate
this document, go to the HP-UX Core docs page at: www.hp.com/go/hpux-core-docs. On this
page, select HP-UX 11i v3.
Use the vxfsconvert or vxupgrade utilities to upgrade older disk layout versions to disk layout
Version 7.
WARNING! Never upgrade the / and /stand file systems to disk layout Version 7. The HP-UX
bootloader does not support disk layout Version 7.
Upgrading VxFS Disk Layout Versions
This section discusses the additional steps required to prepare the file system for being mounted
on all nodes of the cluster. Veritas File System 5.1 SP1 supports Versions 5, 6, 7 and 8 for locally
mounted file systems and disk layout Versions 6, 7 and 8 for cluster mounted file systems. If you
have cluster-mounted file systems with disk layout versions lower than 6, upgrade the disk layout
after upgrading to VxFS 5.1 SP1. Disk layout Versions 1, 2, and 3 are not supported by VxFS 5.1
SP1. All file systems created on VxFS 5.1 SP1 use disk layout Version 7 by default. For more
information on disk layout versios, see the Veritas File System 5.1 SP1 Administrator’s Guide. To
locate this document, go to the HP-UX Core docs page at: www.hp.com/go/hpux-core-docs. On
this page, select HP-UX 11i v3.
