Accessing an engine through a secure shell

This topic describes how to access an engine using a secure shell (SSH) from the master console.

Prerequisites

Before accessing an engine using SSH, the following requirements must be met:
  • You must have a SAN File System administrative user account to sign on to the SAN File System console.
  • You must have a UNIX-based operating system account on the engine to be accessed for use in signing on to the SSH session.
  • If the service representative is accessing the master console remotely, you must have previously initiated a VPN connection with the service representative.

Context

To access the engine using SSH, perform the following steps:

Steps

  1. From the master console, use one of these methods to access the engine:
    1. Open a shell prompt and type putty.exe -ssh engine_IP_address, where engine_IP_address is the IP address of the engine to be accessed.
      Note: If you used SSH to establish a remote session with the master console, type this command from that session to establish an SSH session between the master console and the engine.
    2. Click Start > Programs > PuTTY > PuTTY.
      1. Type the IP address of the engine to be accessed.
      2. Select SSH as the protocol.
      3. Click Open.
  2. Log in using your UNIX-based user ID and password.

Result

After connecting to the engine, you can perform these activities:
  • You can access the SAN File System administrative command-line interface (CLI) to run SAN File System commands. Use these commands to manage engines, metadata servers, and administrative servers.
  • You can access operating-system commands to enable or disable tracing, obtain dumps, and stop or start applications.
