PowerStore: SSH and PowerStore Manager access using the Service LAN Ports

Before you begin 

• This KB only shows how to connect to the system over the Service LAN Ports for SSH and PowerStore Manager (UI) access. For IPMI or SOL access, see the IPMI or SOL access documentation.
• This mode of connection does not display any boot messages or outputs. This is purely SSH and UI connectivity.
• Unlike with IPMI or SOL connection, the system must be in a good state for the required services to be running in order for this to work.  

Finding the correct port

The Service LAN Port location is shown here with number 5.

If in doubt (because one of the nodes is inverted), pay attention to the arrows in the middle of the two ports. Follow the yellow port with the tool (service) symbol.

ATTENTION: Do not remove the management cables as this makes the system inaccessible to the user over the network (affects management only).

Setup

The service laptop being used to connect to the Service LAN Ports should be configured with:

IP: 128.221.1.249
Mask: 255.255.255.0
Gateway: <none> 

The laptop can be physically connected to one of the PowerStore nodes at a time, or to both nodes' Service LAN ports using a small switch or hub.

However, multiple appliances should never be connected to the same hub or switch as the nodes use the same internal IPs. Never connect multiple appliances to the same hub or switch for Service LAN port access.

Once the laptop IP is configured as shown above and the physical connection is established, you can ping the relevant IPs:

Node A: 128.221.1.250
Node B: 128.221.1.251

You should only be able to ping the IPs where you are physically connected to. If you can ping, move to the next section, otherwise check your settings and physical connection.

Usage

• For SSH, connect to the IPs shown above over port 22 using your preferred SSH client.
• For file transfers, SCP protocol must be used instead of SFTP or FTP (see article PowerStore: Understanding shell limitations due rbash and other security implementations for more information). The username for SSH is service, and the password is the password setup during the initial configuration.

• For the PowerStore Manager (UI), use https://128.221.1.250 or 251. UI access requires management services, which only run on the primary node on PowerStoreOS Version 1 and 2, and on the non-primary Node on PowerStoreOS version 3 and higher. If node A's IP does not work, try node B's IP address. The UI (PowerStore Manager) may not be accessible if management services or control path are not running or are experiencing issues.

Example

Access over the normal mgmt IP and the Service LAN IP should produce the same results.
