HP EVA to 3PAR StoreServ Online Import Migration Guide (T5494-96571, January 2013)

• Migration preparation failed
◦ Cause: The preparation process failed to admit volumes on the destination storage system.
Solution: Verify the following:
– The destination CPGs have enough capacity. If they do not, free up enough capacity
in the CPGs or add more capacity to the CPGs on the destination storage system.
– No duplicate volumes exist. This may occur if either a virtual volume with same name
or with the same WWN exists on the destination storage system.
– The required LUN number is available on the host object on the destination storage
system.
– The source volumes are visible to the destination storage system through both paths.
• Migration preparation failed
◦ Cause: The preparation process failed to create a host object on the destination storage
system.
Solution: Verify the following:
– The destination storage system is accessible.
– There is no other host on the destination storage system with a subset of HBA ports
of the host being created.
– There is no host on the destination storage system with a duplicate name but a
different HBA port.
– There is no host on the destination storage system with a duplicate name and a subset
of a HBA port with a different operating system. If a host pre-exists on the destination
storage system, verify that the operating system field contains the correct value.
Possible values are sunsolaris, linux, windows2008, mswindows, hpux, ibmaix.
