• Do not upgrade the operating system and the Veritas products simultaneously.

HP recommends that clients first upgrade the operating system and later upgrade the Veritas

products.

NOTE: In VxFS 4.1 the default disk layout was version 6. File system commands like df, bdf,

fstyp and mount that use the API functions statfsdev (), fstatfsdev (), statvfsdev (), or fsstatvfsdev

() failed because the libc library did not recognize the new Disk Layout Version 6. Applications

using statvfsdev() had to be linked with the new NCF library to recognize Disk Layout Version

In 5.X, the default disk layout is version 7, so the file system commands delivered with this

product have been relinked to support Disk Layout Version 7. However, third-party Applications

must be relinked again in order to recognize Disk Layout Version 7.

The upgrade process:

1. To determine the volume names, enter the following:

a. # bdf

2. To check for DLV 2 or 3 partitions present in the system (since these file systems cannot

be mounted

3. after upgrading to VxFS 5.0), enter the following:

a. # fstyp -v <partition_name>

4. To upgrade file systems with DLV 2 or 3, before installing 5.0, complete the following

steps ( You cannot upgrade from DLV 2 to DLV 4 directly. DLV4 is the lowest disk

layout that is supported by VxFS 5.0.):

a. To upgrade a mounted VxFS file system from DLV 2 to DLV 3, enter the

following:

b. # vxupgrade -n 3 <dir_name>

c. To upgrade a mounted VxFS file system from DLV 3 to DLV 4, enter the

following:

d. # vxupgrade -n 4 <dir_name>

5. Upgrade to the current version of HP-UX 11i , refer to the OS upgrade and Install

guide .

6. Install VxFS 5. X

7. If there are any VxFS file systems, with disk layout 2 or 3 or non-VxFS file systems on

your system, after upgrading to VxFS 5.X, that must be converted to VxFS.

To upgrade to DLV 7 and convert an HFS file system to VxFS, enter the following:

# /opt/VRTS/bin/vxfsconvert <vol_name>

The vxfsconvert command works with unmounted file systems. To upgrade mounted file
