Now we are going to install RAC in Oracle Linux v6 . When I googled Linux related stuff for RAC , I didn't come across documents in which zero padding is done on LUNs meant for ASM Disk groups.
dd if=/dev/zero of=/dev/rdsk/c0t600A0B8008A4CA005ACd0s0 bs=1024k count=2000
Question1. Is zero padding using dd necessary in Linux platform ?No, never did that, not even on Solaris.
Question2. If dd command has to be run in the LUN, shouldn't that be done before we create the partition table ?Of course it should.
