Rename ASM Diskgroup (renamedg) notes

This is how we tested the rename dg command available in11gR2. We used kfed before renamedg was available.

1. Create target disk group
2. Dismount target disk group
3. Do a bcv establish /split
4. Use rename dg renamedg phase=one dgname=FSSBCV_DG newdgname=FSSTGT_DG asm_diskstring='/u01/app/oracle/asm_devices/FSSTGT_DG/*' config=/tmp/renamedg.conf verbose=true
