We need to migrate the storage of our production database. What is the appropriate method of doing so and what specific/generic precautions do we need to take??
Volume Manager - ASM using Raw Disks. ASM External Redundancy as storage is published from storage subsystem
Database version - Oracle 10g R2
Database Size - 5TB approx.
Existing Storage (source): HP MSA 2312sa Dual Controller. Directly connected to our database server (no fc or ethernet switch).
The Oracle binaries are also on this storage
New Storage (Target): HP EVA6300 FC storage. This storage will be connected to the hosts via FC switches.
Can we use host based storage migration like VxVM Plex attach/dettach to copy data from source LUNs to the target LUNs?
Do we have to use Oracle RMAN backup and recovery method for storage migration?
