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.
