When to Convert a File System

5. Use the fscdsconv command to convert the file system to the opposite endian, if required.
See “Converting a File System” on page 43.
6. Make the physical storage and Volume Manager logical storage accessible on the system by
exporting the disk group from the source system and importing the disk group on the target
system after resolving any other physical storage attachment issues. See “Maintaining Your
System” on page 21 for more information.
7. Mount the file system on the target system.
Ceasing Ongoing Migration
To stop performing ongoing migrations and leave the file system on the current system, the enter
the following commands to stop the usage of CDS mechanisms:
# fscdstask limit ignore mount_point
# fscdstask os none mount_point
When to Convert a File System
When moving a file system between different platforms, you might be required to convert the byte
order of the file system. Consider the following information to determine if you must convert a file
system:
◆ You must convert the file system if you are moving the file system between platforms that have
different byte orders (little endian versus big endian).
◆ Conversion is not required when moving a file system between platforms that have the same
byte order.
◆ At present, VxFS for the AIX, HP-UX and Solaris OS platforms is available only on big
endian systems, while VxFS for Linux is available only on little endian systems (x86).
Therefore, byte order conversion is generally only an issue between Linux and these other
operating systems. However, some VERITAS OEMs use VxFS on the x86 version of the
Solaris OS, and therefore have little endian file systems. In such a case, conversion is required
between the Solaris OS on x86 and AIX, HP-UX and the Solaris OS on SPARC, but not
between the Solaris OS on x86 and Linux.
Note VERITAS has never supported moving file systems between different platforms, although in
many cases a user might successfully do so and be able to access the data without trouble.
You cannot move file systems of disk layouts earlier than Version 6 between different
platforms. Doing so can result in data loss or data corruption.
