For this page, we'll assume that we want to use devices /dev/sd[e-z] for ASM. Identify DisksUsed "fdisk -l | grep Disk" to see that /dev/sd[e-z] are the disks we'll use for ASM (they had no partition table).Disk Speed Check
Partition DisksRun this to create disk partitions on partition 4 for ASM use:
