Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)

Make the physical storage and Volume Manager logical storage accessible on

the target 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 “Disk tasks” on page 473.

Mount the file system on the target system.

Stopping ongoing migration

To stop performing ongoing migration

◆

Type the following commands:

# fscdsadm -l ignore mount_point

# fscdsadm -o none mount_point

The file system is left on the current system.

When to convert a file system

When moving a file system between two systems, it is essential to run the

fscdsconv command to perform all of the file system migration tasks. The

fscdsconv command validates the file system to ensure that it does not exceed

any of the established CDS limits on the target, and converts the byte order of the

file system if the byte order of the target is opposite to that of the current system.

Warning: Prior to VxFS 4.0 and disk layout Version 6, VxFS did not officially

support moving file systems between different platforms, although in many cases

a user may have successfully done so. Do not move file systems between platforms

when using versions of VxFS prior to Version 4, or when using disk layouts earlier

than Version 6. Instead, upgrade to VxFS 4.0 or higher, and disk layout Version

6 or later. Failure to upgrade before performing cross-platform movement can

result in data loss or data corruption.

Note: If you replicate data from a little-endian to a big-endian system (or vice

versa), you must convert the application after the replication completes.

Converting the byte order of a file system

Use the fscdsconv command to migrate a file system from one system to another.
