Configuring Basic Storage Services

Configuring Basic Storage Services

Configure the storage system to divide the storage space into LUNs, and map them to application servers so that the application server can read and write the storage space provided by the storage system.


This section briefs the major procedures and reference commands for configuring basic storage services. For details, see descriptions of the corresponding commands.

Table 1-1 describes the major procedures for configuring basic storage services.

Table 1-1 Major procedures for configuring storage space





Creating storage space

Creating a disk domain

A disk domain provides storage space for storage pools, whose storage tiers and available capacities depend on the disk types, capacity, and hot spare policy of the disk domain. The storage system automatically allocates hot spare space with different capacities based on hot spare policies to take over data from failed member disks.

create disk_domain

Creating a storage pool

The storage space used by application servers is provided by the storage pools on the storage system.

create storage_pool

Creating a LUN

A LUN indicates a logical unit in storage space.

create lun

Creating a LUN group

A LUN group is a set of LUNs. Only LUN groups can be added to a mapping view.

create lun_group

Setting up a connection

(Optional) Adding Route (iSCSI connection)

If the IP addresses of the Ethernet port on a storage system and the service network port on an application server are on different network segments, or if two storage system reside on different local area networks (LANs), add a route for the Ethernet port of the storage system to establish a connection to the application server or the other storage system.

Creating a host

A host is a virtual concept of an application server. An initiator is added for a host to establish a connection with the application server.

create host

Creating a host group

A host group is a set of hosts. Only host groups can be added to a mapping view.

create host_group

Configuring an initiator

An initiator must be configured on an application server to set up an iSCSI connection between the application server and storage system.

(Optional) Configuring CHAP authentication (iSCSI connection)

CHAP authentication is configured to restrict the access to the storage system from application servers.

change initiator

(Optional) Creating a port group

Multiple ports can be logically added to a port group to facilitate port management.

create port_group

Creating a mapping view

The application server corresponding to a host in a host group can use the storage space designated by a LUN in a LUN group only after the host group and LUN group are added to the same mapping view.

create mapping_view

Configuring the host-storage connectivity

For details, refer to the Configuring Connectivity chapter in the Huawei SAN Storage Host Connectivity Guide for XXX. XXX represents a specific operating system, for example, Windows.


Making storage space available

Making storage space available

Application servers must scan for hard disks to detect the LUNs mapped by the storage system and use the storage space. For details, see the Huawei SAN Storage Host Connectivity Guide for XXX.
