I am planning to build a 3-node production RAC cluster. My shop only has RAC clusters built on 11.2.0.4 GI.
It has been a while since I built a RAC cluster. Back in the day, I used ASMLib to achieve the following :
- Preserve SAN LUN's ownership across server reboots
- Preserve SAN LUN's permissions across server reboots
I've read about ASM Filter driver (ASMFD) which seems to be an newer alternative for ASMLib.
Should I be using ASMLib or ASMFD ?
Any other major changes in the ASM world since 2015, which I should be mindful about ?
