Make sure the following restrictions are followed when you use XP Continuous Access volumes in
Duplex status as XP Auto LUN volumes.
•
Set I/O rates less than 50 IOPS while migrating volumes.
If the I/O rate is 50 IOPS or more, volumes may not be migrated.
•
If a connection failure has occurred between the MCU and the RCU, remove the failure, and
then migrate the volume.
•
If an external volume or a TP-VOL is used, information about the volume is displayed on the
Remote Web Console of the remote storage system. When the volume migration is completed
and the XP Continuous Access Asynchronous pair is suspended and resynchronized, the
information about the volume will be updated.
•
Do not migrate P-VOLs and S-VOLs at the same time.
Timeout of the host I/O occurs if you migrate P-VOLs and S-VOLs at the same time.
•
Do not change the status of the volume while migrating volumes.
While migrating volumes, even if you try to change the status of the volume, the status may
not change.
