RAC Installation with ASM on a RAW Disk
652072Jul 26 2008 — edited Jul 27 2008Hi Frens,
I am going to install RAC on HP-UX 11iv3...
Our HP-vendor created one LUN sizing arround 50G as required by my client....
Now, I wanna install RAC sharing this LUN for 2 nodes .... as it is required to be a two node Cluster......I am going to keep all OCR files, Voting Disk and Database files on the RAW Disk...... How can i start installing the RAC ? As per as OCR and Voting disk is concerned, RAW Disk would be shared and the DB Files are concerned .....the same RAW Disk would be shared..but with ASM....... Can some body help me?.....hou can i create RAW Disk partitions?....i am not aware of RAW Devices .....never worked on it .......I have a confuzion here.....Vendor told me .......bofdb is the created LUN and later he renamed it to bofdb fomr disk6....
