Just a little ‘face lifting’ old one instruction how to connect asm disks from old to new server.

1. Install Grid software only
2. execute as root user(standalone instance): $ORACLE_HOME/perl/bin/perl -I $ORACLE_HOME/perl/lib -I $ORACLE_HOME/crs/install $ORACLE_HOME/crs/install/roothas.pl
3. install asm OS rpm pakage
4. connect disks from old server to new server
5. check ORACLEASM_SCANORDER in /etc/sysconfig/oracleasm Doc ID 1384504.1, to discover your disks
6. add asm instance in clusterware: srvctl add asm
7. start asm: srvctl start asm
8. open asmca or sqlplus and check/mount diskgroup

Note: Diskgroups across server have to be unique, if disks from old server has same names as on new one, you have to rename it.
