How to Add LUNs to Disk Sets

From phys-sun, list the DID mappings.

Output is similar to the following, where WWN stands for the unique World Wide Number (WWN) of the disk target.

phys-sun# cldevice show | grep Device
=== DID Device Instances ===                   
DID Device Name:                                /dev/did/rdsk/d1
  Full Device Path:                                phys-sun:/dev/rdsk/c0t0d0

Map LUN0, LUN1, and LUN2 to their DID device names.

Compare the information that you saved when you created the LUNs with the output of the cldevice command. For each LUN, locate the /dev/rdsk/cNtWWNdY name that is associated with the LUN. Then find that same disk name in the cldevice output to determine the DID device name.

These procedures assume the following mappings for the purposes of this example. Substitute your own disk names and DID names when you perform the remainder of these procedures.

Data Service	LUN Name	Raw Disk Device Name	DID Name
Sun Cluster HA for Oracle	`LUN0`	`/dev/did/rdsk/c1tWWNd0`	`dsk/d3`
Sun Cluster HA for NFS	`LUN1`	`/dev/did/rdsk/c1tWWNd0`	`dsk/d4`
Sun Cluster HA for Apache	`LUN2`	`/dev/did/rdsk/c0tWWNd0`	`dsk/d5`

Take ownership of the Oracle disk set oraset.

phys-sun# cldevicegroup switch -n phys-sun oraset

Add LUN0 to the Oracle disk set.

Use the full DID path name.
phys-sun# metaset -s oraset -a /dev/did/rdsk/d3

Verify that the configuration of the disk set is correct.
phys-sun# metaset -s oraset

Repeat the process to add LUN1 to the NFS disk set nfsset.

phys-sun# cldevicegroup switch -n phys-sun nfsset
phys-sun# metaset -s nfsset -a /dev/did/rdsk/d4
phys-sun# metaset -s nfsset

Repeat the process to add LUN2 to the Apache disk set apacheset.

phys-sun# cldevicegroup switch -n phys-sun apacheset
phys-sun# metaset -s apacheset -a /dev/did/rdsk/d5
phys-sun# metaset -s apacheset
