Hi,
I'm trying to outline the steps to migrate an Oracle RAC (using ASM volumes) environment to SFRAC. Do you think the following steps are enough?
Our setup will be similar to this:
---RAC-1 ---
SAN--| |------------------------|-- Oracle with Single Node --|--SAN
---RAC-2 ---
OC Site DR Site
System on OC Site contains 2-node Oracle RAC Cluster with ASM volumes on SAN and DR Site will contain a single node Oracle
1. Install SFRAC without configuration on DR site
2. Reboot nodes on DR site
3. Backup Servers on OC site (Both Oracle and Filesys)
4. Install SFRAC without configuration on OC site
5. Reboot nodes on OC site
6. If ASM volume encapsulation is possible:
a. shutdown database
b. Encapsulate asm volumes to take them under vxvm control
c. Startup database and check if the databases are working
7. If ASM volume encapsulation is not possible:
a. Create a new volume under vxvm control with the same size as the current ASM volume.
b. Tell the customer to make this new volume to be ASM volume
c. Tell the customer to mirror/copy current ASM volume to new ASM volume
8. After ASM mirroring/copying is complete, disable/remove the current ASM volume and make the new ASM volume current
9. Create new volumes on DR site with the same size
10. Tell the customer to make the new volume as ASM volume on DR site (Oracle must be installed first, of course)
11. Create other VVR volumes on both sites
12. Configure SFRAC on both sites (vxfen, llt, resources etc)
13. Shutdown Oracle on OC site
14. Start Oracle processes under VCS
15. Start replication
16. Create FireDrill resources on DR site to check if replication is OK
