Storage System Configuration

Configuring Port IP Addresses

• Storage systems use logical ports to establish iSCSI connections with hosts. The home ports of logical ports can be physical Ethernet ports, bond ports, or VLANs.
• In this document, the home ports of logical ports are physical Ethernet ports. If you want to bond the home ports of logical ports or configure VLANs on the home ports, configure the storage system ports by following instructions in the Basic Storage Service Configuration Guide for Block before configuring the connectivity.
• If the home ports of logical ports are physical Ethernet ports, you can configure IP addresses for the logical ports on DeviceManager using either of the following methods:
  • Method 1: Choose System > Hardware. In the rear view of the device hardware, select the desired Ethernet port and configure an IP address. This document uses this method as an example.
  • Method 2: Choose Services > Network > Logical Ports and click Create. On the Create Logical Port page, select the desired Ethernet port and configure an IP address.

Configure Ethernet port parameters to ensure proper communication between the storage system and application server.

Note the following items when setting the properties of an Ethernet port:

• The IP address of the Ethernet port must not be in the 127.127.127.XXX segment and the gateway address must not be 127.127.127.10, 127.127.127.11, 127.127.127.12, or 127.127.127.13. Otherwise, routing will fail. This is because the default internal heartbeat IP addresses of a dual-controller storage system are 127.127.127.10 and 127.127.127.11, and those of a four-controller storage system are 127.127.127.10, 127.127.127.11, 127.127.127.12, and 127.127.127.13. Internal heartbeat links are established between controllers for these controllers to detect each other's working status. You do not need to separately connect cables. In addition, internal heartbeat IP addresses have been assigned before delivery, and you cannot change them.
• The IP address of the Ethernet port cannot be in the same network segment as that of a management network port.
• The IP address of the Ethernet port cannot be in the same network segment as that of a maintenance network port.
• If the Ethernet port connects to an application server, the IP address of the Ethernet port must be in the same network segment as that of the service network port on the application server. If the Ethernet port connects to another storage device, the IP address of the Ethernet port must be in the same network segment as that of the Ethernet port on the other storage device. Add routes if available IP addresses in the desired segment are insufficient.

To configure an IP address for an Ethernet port, perform the following steps:

1. On DeviceManager, choose System > Hardware.

   • The GUI may vary with the product model and version.
   • For OceanStor Dorado 6.0.1 and later versions, choose System > Hardware > Devices to view the device hardware.

2. Select a device and click to switch to the rear view.

3. Select the desired Ethernet port and click Modify.

4. On the page that is displayed, set the port name, IP address, and subnet mask.

5. Click OK.
   The system prompts that the configuration is successful.

6. Verify that the IP address is configured successfully.

Adding an Initiator to a Host

This section details how to add initiators to the hosts on the storage system. For details on how to create hosts and mappings, see the Basic Storage Service Configuration Guide corresponding to your storage system.

1. Log in to DeviceManager. On the Hosts page, select the desired host, click on the right, and choose Add Initiator.
   Figure 5-22 Adding an initiator
   

2. Check whether the host initiators can be discovered.

3. Select the desired initiators and click .

4. Click OK.

5. Confirm the information and click OK.

6. Click the host name and check the initiators. Ensure that the Status of the initiators is Online.

   In iSCSI SAN Boot scenarios, if the initiator connection status is offline, refer to On an iSCSI Network, the Initiator Cannot Be Connected When SAN Boot Is Configured Using a Storage LUN.
