• Vdisk size

• Vdisk WWN

• Name of the vSphere server name from which the datastore was created

Creating the convention

HP recommends naming VMFS datastores and RDMs in vCenter with the same name used when creating the Vdisk in

Command View EVA or when using SSSU scripting tools. While this approach is beneficial, it may require some coordination

with the storage administrator.

Note

When creating Vdisks in Command View or SSSU, Vdisk names are unique to the particular array.

In a vSphere cluster, ESX prevents you from creating datastores with the same name, regardless of the array they are

created on. This capability yields an environment where datastore names are unique across the entire infrastructure, while

RDM names are unique to the particular vSphere host – or, depending on your choice of names, to the entire infrastructure.

Using descriptive naming

When creating Vdisks in Command View EVA, HP recommends using descriptive naming for the datastore. For example, a

suitable naming convention might be as follows:

<Location>_<Location Attribute>_<Department>_<Vdisk Type>_<Usage>_#

Table 7 outlines the various components of this naming convention.

Table 7. Sample naming convention

Component

Description

Example

Geographical location of the team, group or division for

which the storage is being allocated

The location could be a city, state,

country, or a combination thereof.

Specific attribute of the particular location, such as an

office building floor or the scope of the department

• Building R5

• Third floor

Job function of the team, group or division for which the

storage is being allocated

• IT

• Sales

• Finance

Type of Vdisk

• RDM

• VMFS (datastore)

<Usage>

How the Vdisk will be used

• VM boot

• Exchange logs

• Exchange data

• Oracle_archLogs

• Oracle_data

<#>

Provides enumeration in the event that multiple disks

with the same name should be needed

• 1

• 0002

The following are examples of this sample naming convention:

• Houston_Enterprise_Sales_VMFS_VMBoot_1

• Houston_Enterprise_Sales_VMFS_VMBoot_2

• LA_Corporate_IT_RDM_ExchLogs_1

• LA_Corporate_IT_RDM_ExchLogs_2
