UNIX OS (HP_UX, Linux, AIX, Solaris)
On UNIX operating systems—HP_UX, Linux, AIX, and Solaris—If volumes are
managed through logical volume managers, follow these general guidelines:
 Export the volume before migration begins.
 Import the volume after migration is complete and destination LUNs are
presented to the server.
If volumes are not managed through a logical volume manager in the system, it is
very important to follow the pre-migration checklists to identify the physical device
node(s) (/dev/rdsk/c0t1d1) on which the volume is mounted. After data
migration, the physical device node may change. Change the volume mount such
that it now it points to the new physical device (dev/rdsk/c0t2d5).
To discover current active mount points, issue the mount command on the
system console.
Some applications, such as the Oracle Cluster File system (OCFS) may directly
use the raw devices. Consult the system administrator. OCFS may automatically
discover the migrated devices. Follow the procedure listed in OCFS manual.
In addition, QLogic recommends that the destination LUN size is equal to the
source LUN size. Expand the destination LUN after the migration is complete and
the migrated volume is remounted.
If you are running Veritas Volume Manager on any of the UNIX operating
systems, the destination LUN size must be greater than the source LUN size.
