Hi Guys,
I'm new to RAC & ASM. Especially new to SAN storage.
Managed to setup in Oracle Virtualbox for learning purpose referencing the guide Apps DBA Workshop: Oracle 12c RAC Installation on oracle solaris 11.1 on Vmware.
Let's say in a real world production environment where we have a SAN storage managed by a storage administrator.
What is the right term I should use to communicate/request the storage administrator to present the disks (eg, c9t0d0 as below) to both the servers so that i can perform the below and continue my setup?
Are all the below disks presented as LUN or Raw Disk Partition to the servers?
In the guide:
Formatting of disks:
