Data migration flow using the Storage Migration function
The workflow sequence for Storage Migration is described below.
The host environment must be confirmed and saved before performing the Storage Migration. Ask the system
administrator to do it.
(1)Preparation
a Check and save the host environment so that the ETERNUS DX disk storage system can be used in
the same environment after migration.
b Check the status of the source and destination storage systems and clear any sense information that
has not been reported (*1).
c When migrating data with multipath, make the configuration so that the same affinity group (LUN
group) can be accessed from the multiple FC ports used for migration at the source storage system.
d Create a destination volume in the destination storage system, or format an existing volume for use
as the destination volume.
(2)Download a template for the Storage Migration setting file ("11.2.11.2 Download Template File for Storage
Migration Settings" (page 912)).
(3)Create the Storage Migration setting file. Refer to "Appendix I Storage Migration Setting Files" (page 1019)
for details.
(4)Stop access from the host to the source volume.
(5)Change the mode of the FC port used for migration in the destination storage system to "Initiator"
("9.2.3.11 Modify Port Mode" (page 571)
).
(6)Set port parameters to the FC-Initiator port ("9.2.3.7 Modify FC Port Parameters" (page 531)
).
(7)Connect the source and destination storage systems using an FC cable, or use a switch to connect the
source and destination storage systems.
(8)Load the "Storage Migration setting file" that has been created in Step (3)
to start Storage Migration
("11.2.11.1 Start Storage Migration" (page 906)
).
(9)Check the progress of Storage Migration.
(10)Operation after Storage Migration is complete:
a Delete the migration path after Storage Migration is completed successfully ("11.2.11.3 Delete
Storage Migration Path" (page 914)).
b Change the FC-Initiator port mode from "Initiator" to "CA" ("9.2.3.11 Modify Port Mode" (page 571)
).
c Set port parameters to the FC-CA port ("9.2.3.7 Modify FC Port Parameters" (page 531)
).
d Set host affinity to the FC-CA port ("9.2.1.1 Create Host Affinity" (page 414)
or "9.2.1.3 Modify Host
Affinity" (page 428)).
e Confirm that the destination storage system and volumes can be accessed correctly from the host.
