5.
After the data is migrated for the specified server or cluster, present the destination LUNs to the
server or cluster by changing the fabric zoning and LUN presentation from the array.
6.
Reboot the server, and then validate that the new LUNs are seen by the system and that the
volumes are mounted on the destination LUNs.
Validating integrity of the data
If there is a file system on the LUN, perform a quick file system check by bringing up the application
and confirming access to the data.
Operating systems dependencies
If the source array type is different from the destination array type, you may need to install the new
multi-pathing software associated with the destination array.
CAUTION:
Do not expose the destination LUNs to a server until the data migration is complete and server access
to the source LUN is removed.
Windows operating system
Migrating data for Windows servers is not difficult. Windows offers two types of disks: basic disks
and dynamic disks. In most cases, Windows discovers the migrated volumes whenever migrated LUNs
are seen by the server.
Take the following precautions:
•
Do not create new drive letters while data migration is in process.
•
Ensure that the destination LUN size is equal to or greater than the source LUN size.
NOTE:
A dynamic disk may appear in an offline state. after migration and even after presenting the new
LUN to the server. To bring the disk to an online state:
1.
In the Device Manager, right-click the disk.
2.
Depending on the Windows OS version, click either
Import Foreign Disk
or
Reactivate Disk
.
When all dynamic disks are brought back online, the volume will be mounted for application
access.
UNIX operating system (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.
