3 Upgrading to Base-VXFS 4.1 and

Base-VXVM 4.1

This chapter discusses how to upgrade from VxFS 3.5 and VxVM 3.5 to Base-VXFS 4.1 and

Base-VXVM 4.1 respectively.

Upgrading to Base-VXFS 4.1 from VxFS 3.5

The installation of Base-VXFS 4.1 replaces the functionality provided by the VxFS 3.5 bundle

in the Core OS on HP-UX 11i v2. For more information on installing Base-VXFS 4.1 see

“Installing Base-VXFS 4.1” on page 18.

NOTE The VxFS 4.1 default disk layout is version 6. If you remove VxFS 4.1, the

VxFS 3.5 functionality returns automatically only if the disk layouts for

directories / and /stand are not changed to version 6.

The VxFS installation changes the /stand/system ﬁle and rebuilds the kernel. If you have

used a system conﬁguration ﬁle other than /stand/system to conﬁgure your current kernel,

you must copy your conﬁguration changes to the /stand/system ﬁle. Otherwise, the kernel

built does not contain your conﬁguration changes when installing with vxinstall.

NOTE VxFS 4.1 supports new Disk Layout Version 6. File system commands like df,

bdf, fstyp and mount that use the API functions like statfsdev (),

fstatfsdev (), statvfsdev (), fsstatvfsdev () will fail as libc library

does not recognise the new Disk Layout Version 6. Applications using

statvfsdev() must be linked with the new NCF library to recognize Disk

Layout Version 6.

Upgrading to Base-VXVM 4.1 from VxVM 3.5

The installation of Base-VXVM 4.1 replaces the functionality provided by the VxVM 3.5

bundle on HP-UX 11i v2. Installation of the VxVM 4.1 bundle on HP-UX 11i v2 removes the

VxVM 3.5 components. If the VxVM 4.1 bundle is removed for any reason, the VxVM 3.5

bundle has to be re-installed on your system. For more information on installing Base-VxVM

4.1 see “Installing Base-VXVM 4.1” on page 23.
