ASM HA
Hi dear experts !
I have Grid Infrastructure 11gR2, RAC 2 node installed with ASM.(OEL 5.7 UEK)
ASM is configured with 3 diskgroup (normal redundancy ). First diskgroup contain
5 Virtual Disks and each disk is assigned to its own failure group. Also I have two failure
group each of which have 3 Virtual Disks (Oracle VM 3.0.3). Virtual Disks are connected to server via NFS.
Currently I am testing ASM behavior in situation when one of this failure group will be down.
As my ASM disks are virtual and each failure group (3 v. disks) are located in separate machine
I simulate crash the disks by dropping network interface. So after I kill connection between
Linux and storage (NFS) my DB (with 2 failure groups) has crashed. When connection
is became available Linux and ASM instance without reboot can collaborate with disks and
I manually *(srvctl start database -d test)* start DB.
My question is how can I configure (if Oracle supports of course )
ASM that DB continues to work even after one of disk group become unavailable.
Can I set up something ASM HA ?
any ideas are welcome
./thanks
