Configuring iSCSI IP Addresses in a Batch

Prerequisites

The iSCSI service has been enabled on a server.

Procedure

1. Choose Resources > Access > Service Network.
2. Select servers whose iSCSI IP addresses you want to configure and click Configure iSCSI IP Address.

   The Configure iSCSI IP Address page is displayed.

3. Configure the iSCSI IP address. Table 1 describes related parameters.
   

   The storage system supports both IPv4 and IPv6 addresses. You are advised to configure both IPv4 and IPv6 addresses.

   Table 1 iSCSI IP address parameters

   Parameter	Description
   IP Address Range	iSCSI IP address range of the servers configured in batches. IPv4 and IPv6 addresses are supported. After you specify this parameter, the system will automatically assign an IP address within this range to each server. NOTE: The service network (iSCSI network) cannot use the same subnet as the management, storage, or control network. If no IP address is configured for a selected port, the system assigns an IP address within the specified IP address range to the port. If an IP address has been configured for a selected port, the system reads the configured storage IP address within the specified IP address range. The number of IP addresses in this IP address range must be greater than or equal to the number of servers. If the iSCSI IP addresses of the servers are not in the same network segment, click to set multiple network segments for the iSCSI IP addresses of the servers. In addition, each port can be configured with both IPv4 and IPv6 network segments so that compute nodes can access servers using IPv4 or IPv6. In the event of using an IPv4 address: A 32-bit IPv4 address is divided into four 8-bit fields that are expressed in dotted decimal notation. Each field of the IPv4 address must be an integer. The value of the leftmost field ranges from 1 to 223 (excluding 127). The values of the other fields range from 0 to 255. An IPv4 address cannot be set to a special address such as a broadcast address. Example: 192.168.1.100 In the event of using an IPv6 address: A 128-bit IPv6 address is divided into eight 16-bit fields. Each 16-bit field consists of four colon-separated hexadecimal numbers. In each 16-bit field, leading zeros can be omitted for simplicity. However, at least one digit must be reserved in each field. To achieve further simplicity, you can use a double colon (::) in place of a series of zeros. A double colon can be used only once in an IPv6 address. It can also represent the neighboring consecutive zeros at the beginning or end of an IPv6 address. An IPv6 address cannot be set to a special one, such as a network address, loopback address, or multicast address. Example: fc00::1234
   Subnet Mask/Prefix	When an IPv4 address is used, this parameter indicates the subnet mask of the IP address and identifies the subnet to which the IP address belongs. When an IPv4 address is used, this parameter indicates the prefix length of the IPv6 address.
   Port	Port for which the iSCSI IP address will be configured. NOTE: Click . In the Manage Bond Port dialog box that is displayed, set related parameters of bond ports.
   Operation	Modify and Remove operations are provided.

4. Click Preview.

   Preview the iSCSI IP addresses and ports of the servers in the list below.

   

   • Click More on the right of a server that you want to modify and select Modify. On the Modify page that is displayed, you can change the iSCSI IP address and port of the server.
   • Click More on the right of a server that you want to modify and select Manage Bond Port. On the page that is displayed, you can set a bond port of the server.

5. Click OK.
6. Confirm your operation as prompted.
