Workaround: In order for the createmigration command to complete successfully, the EMC Storage controller failover mode must be set to 4 (Active/Active). Failover Mode 4 is ALUA. This allows the HP 3PAR peer port initiators to access LUNs through the noncontrolling EMC SP controller.

The EMC Storage controller failover mode may be displayed and edited by using EMC Naviseccli CLI commands.

To display the current default EMC Storage controller failover mode, execute the following EMC Naviseccli CLI command:

C:\> naviseccli -address <SP Controller IP address> failovermode Current failovermode setting is: 1

Any value other than 4 (Active/Active) indicates either a configuration issue or a hardware/software issue with the EMC Storage controller. The issue must be corrected before proceeding with data migration.

To change the EMC Storage controller failover mode, follow these steps:

1.Configure the EMC storage controller failover mode to 4 (Active/Active). This may require resolving any hardware/software or configuration issues which may have led to the condition.

Example 69 Editing the default EMC Storage controller failover mode

C:\> naviseccli -address <SP Controller IP address> failovermode 4 WARNING: Previous Failovermode setting will be lost!

DO YOU WISH TO CONTINUE (y/n)? y

2.Unzone the HP 3PAR peer ports from the EMC array.

3.Deregister the HP 3PAR Peer Port initiators from the EMC array.

4.Rezone the HP 3PAR peer ports with the EMC array.

IMPORTANT: Each HP 3PAR Peer Port initiator must have its failover mode set to 4 before you execute the createmigration command.

Error when Importing LUN of Size Smaller than 256 MB

Problem: After a createmigration command is executed with a LUN of size less than 256 MB,

the following message occurs following a showmigration command: "OIUERRDST0008: Admit has failed ..."

Solution: Increase the size of the source LUN on the EMC Storage array to a minimum of 256 MB, and then retry the createmigration command.
