Naming convention for SmartClone volumes
A well-planned naming convention helps when you have many SmartClone volumes. Plan the
naming ahead of time, since you cannot change volume or snapshot names after they have been
created. You can design a custom naming convention when you create SmartClone volumes.
Naming and multiple identical disks in a server
Mounting multiple identical disks to servers typically requires that servers write new disk signatures
to them. For example, VMware ESX servers require that resignaturing be enabled and will
automatically name duplicate datastores. Most servers allow the duplicate disks to be renamed.

Server access
Plan the servers you intend to assign to the SmartClone volumes. Configure the servers before
creating the volumes, and you can then assign the servers when you create the volumes. See
“Controlling server access to volumes” (page 199) .
Defining SmartClone volume characteristics
When creating SmartClone volumes, you define the following characteristics.
Table 60 Characteristics for new SmartClone volumes
Definition SmartClone volume
characteristic
The number of SmartClone volumes you want to create. You can create up to 25 as one
operation in the CMC, and then repeat the process to create the desired number of SmartClone
volumes. Use the CLI to create larger quantities of SmartClone volumes in a single operation. Quantity
The name of the SmartClone volume that is displayed in the CMC. A volume name is from 1
to 127 characters and is case sensitive. The name cannot be changed after the volume is
created. SmartClone Name
SmartClone volumes default to Thin Provisioning. You can select Full Provisioning when you
create them. You can also edit the individual volumes after they are created and change the
type of provisioning. Provisioning
Server assigned to the volume. While you can only assign one server when you create
SmartClone volumes, you can go back and add additional clustered servers later. For more
information, see
“Assigning iSCSI server connections access to volumes” (page 208) .

Type of access to the volume: Read, Read/Write, None Permission
