HP-UX 11i v3 Installation and Update Guide, March 2009 (Update 4 Release)

Table A-1 Known Install and Update Problems (continued)
Description/ActionProblem
If VxFS 5.0 has been used to create file systems with disk layout
version 7, those disks will not be readable by the VxFS 4.1 for HP-UX
11i v3.
What To Do
If you plan to update to 11i v3 with VxFS 4.1, then, before updating
to 11i v3, copy data from your DLV 7 file systems and onto file
systems created at layout version 5 or 6. This step is not required if
you plan to update to 11i v3 with VxFS 5.0, because the 11i v3 VxFS
5.0 can read DLV 7 file systems.
Updating to HP-UX 11i v3 from
HP-UX 11i v2 with VxFS 5.0
If you have created any VxFS file system with disk layout version 2
or version 3, these file systems cannot be mounted under VxFS 4.1
on HP-UX 11i v3.
What To Do
Use the vxfsconvert command to upgrade the disk layout to
version 4 before upgrading to VxFS 4.1 on HP-UX 11i v3. See the
Veritas 4.1 Installation Guide for more information on VxFS 4.1.
