Run the scdidadm(1M) command to find the raw device identity (DID) that corresponds to shared disks that are available in the cluster.
The following example lists output from the scdidadm -L command.
# scdidadm -L 1 phys-schost-1:/dev/rdsk/c0t2d0 /dev/did/rdsk/d1 1 phys-schost-2:/dev/rdsk/c0t2d0 /dev/did/rdsk/d1 2 phys-schost-1:/dev/rdsk/c0t3d0 /dev/did/rdsk/d2 2 phys-schost-2:/dev/rdsk/c0t3d0 /dev/did/rdsk/d2
Use the DID that the scdidadm output identifies to set up the disk in the ASM disk group.
For example, the scdidadm output might identify that the raw DID that corresponds to the disk is d2. In this instance, use the /dev/did/rdsk/d2sN raw device, where N is the slice number.
Modify the ASM_DISKSTRING parameter to specify the devices that you are using for the ASM disk group.
For example, to use the /dev/did/ for the ASM disk group, add the value /dev/did/rdsk/d* to the ASM_DISKSTRING parameter as follows:
ASM_DISKSTRING = '/dev/did/rdsk/*'

Ensure that all other storage management schemes that you are using for Oracle files are installed.
After all storage management schemes that you are using for Oracle files are installed, go to Preparing the Sun Cluster Nodes.
