EMC Open Migrator (AIX)

• Open Migrator has no requirement for EMC Enginuity, Solutions Enabler.
• Both source and target volumes remain synchronized until the session is deactivated.
•  Does not support Boot disk(root file system devices) migration and automatic volume expansion
• EMC don't recommend you migrate jfs/jfs2 log volumes on AIX.

# installp -ad ./EMCom_install EMCom


Operation:

1. Create a device file that contains a list of the source and target volume pairs for the operation. Two columns, one for source and one for target separated by spaces or tabs.
/dev/rdsk/c16t0d0 /dev/emc/rdsk/ora1_tgt_9/vol4
/dev/rdsk/c16t0d1 /dev/emc/rdsk/ora2_tgt_9/vol5
/dev/rdsk/c16t0d2 /dev/emc/ora3_tgt_9/rvol6
2. Create a session by using stormigrate create command. The session can be used to migrate or compare data. Then add volume pairs to session.
# stormigrate create -session session1 -file volume_pairs_1
# stormigrate list
# stormigrate show -session session1
# stormigrate activate -session session1
# stormigrate copy -session session1
