Hello Oracle DBAs,
We have some problems with DM multipath ( mixed SCSI and ISCSI devices) =>
oracle instance can fall.
So we plan to use NFS for the quorum disks.
I have some questions :
1) many people use hard options for NFS, but oracle recommended soft
options => not a big fan of hard option, why people not follow it ?
2) oracle recommend now one quorum disk for each diskgroup for steched
cluster, but i did not see people use it
3) 18C => oracle do not support NFS for Voting and OCR , What does it mean ?
4) Does someone try to use exetend cluster configuration with RAC in
production ?
If people have recommendations about NFS usage with Rac extended clusters,
i will appreciate.
Thank you
