vxupgrade(1M) vxupgrade(1M)

• HP-UX 11.0 with JFS 3.3 from Application CD

• HP-UX 11.1x

You cannot upgrade the root (

/)or/usr ﬁle systems to Version 4 on an 11.0 system running JFS 3.3 from

the Application CD. Additionally, we do not advise upgrading the

/var or /opt

ﬁle systems to Version 4

on an 11.0 system. These core ﬁle systems are crucial for system recovery. The HP-UX 11.0 kernel and

emergency recovery media were built with an older version of JFS that does not recognize the Version 4

disk layout. If these ﬁle systems were upgraded to Version 4, your system would fail to boot with the 11.0

kernel as delivered or the emergency recovery media. You can, however, upgrade these core ﬁle systems to

Version 4 on an HP-UX 11.1x system.

Disk layout versions cannot be downgraded, for example, you cannot change a ﬁle system from disk layout

version 4 to disk layout version 3.

A ﬁle system cannot be upgraded from a Version 3 disk layout to a Version 4 disk layout if its intent log size

is less than 256 kilobytes.

After upgrading from a Version 2 disk layout, run

fsadm -c mount-point to convert the inode format to

allow growth beyond a two-gigabyte offset.

RETURN VALUE

vxupgrade returns the following values:

0 Successful completion.

1 Upgrade failed due to lack of disk space.

2 Some other error occurred.

32 Speciﬁed mount_point is not a VxFS ﬁle system.
