By default, the ALTER DISKGROUP statement does not wait until the operation is complete before
returning. Query the V$ASM_OPERATION view to monitor the status of the ASM disk rebalance
operation.
Post Migration Tasks
1. As user oracle, register the database and database instances as the cluster resources from node
1 of the target RAC cluster.
srvctl add database -d db_unique_name -o oracle_home
srvctl add instance -d db_unique_name -i inst_name -n node_name
For example,
$ srvctl add database -d migrtst -o /u01/app/oracle/product/11.1.0/db_1
$ srvctl add instance -d migrtst -i migrtst1 -n w23-r720-m-top
$ srvctl add instance -d migrtst -i migrtst2 -n w23-r720-m-bot
2. Remove access to the Dell|EMC disks from the target PowerEdge R720 servers.
3. Remove zoning to Dell|EMC disks from the Brocade switches.
4. Detach Dell|EMC storage from Brocade switches.
Key Benefits of the Migration Solution
To summarize, the key strengths of the migration solution provided in this paper are:
 The migration solution is near zero downtime, typically less than one minute and in most cases only
seconds.
 The migration solution utilizes native Oracle database feature, without incurring additional license
cost to purchase additional migration tools.
