Enclosure-based naming operates as follows:
All fabric or non-fabric disks in supported disk arrays are named using the enclosure_name_# format. For example, disks in the supported disk array, enggdept are named enggdept_0, enggdept_1, enggdept_2 and so on.
You can use the vxdmpadm command to administer enclosure names.
Disks in the DISKS category (JBOD disks) are named using the Disk_# format.
Disks in the OTHER_DISKS category (disks that are not multipathed by DMP) are named using the c#t#d#s# format.
By default, enclosure-based names are persistent, so they do not change after reboot.
If a CVM cluster is symmetric, each node in the cluster accesses the same set of disks. Enclosure-based names provide a consistent naming system so that the device names are the same on each node.
To display the native OS device names of a VM disk (such as mydg01), use the following command:
# vxdisk path | grep diskname
