One Diskgroup or two Diskgroups for OCR and VOTING (11G R2) ?
I am using Oracle 11g R2 with Solaris 10 & EMC shared external disks (external redundancy from EMC's technology):
I will ask to the storage administrator in order to create 3 LUNs (2GB each), to locate the OCR and Voting files.
Should I create only one Diskgroup for OCR & Voting (OCR_VOTE_DISK) using these 3 LUNs ?,
or
Is it better to create one Diksgroup for OCR and another Diskgroup for Voting (in these second scenario the storage administrator will create for 3 LUN more to locate Voting files) ?
I'd appreciate any suggestion / comments ?
Regards,
Jose
