Accessing the SAN Volume Controller CLI

If you must enter and run command-line instructions, you can access the SAN Volume Controller command-line interface (CLI) from the server where the SAN Volume Controller Console is installed.

1. Start PuTTY by clicking Start > All Programs > PuTTY > PuTTY or by going to the directory and double-clicking the putty.exe file. If the server is configured to use PuTTY for command-line access, the session settings might be saved. The SAN Volume Controller Console installation package includes PuTTY, which you can use to connect to the SAN Volume Controller cluster over either IPv4 or IPv6. You must use PuTTY 0.60 or a higher version to connect to a SAN Volume Controller cluster that has an IPv6 address.
   Note: The cluster can have two management IP addresses; therefore, you might see more than one saved session.
   If the cluster is not listed under Saved sessions, ask the customer to set up PuTTY for command-line access and then restart this procedure. The PuTTY Configuration panel for the Session category contains the details that need to be filled in before PuTTY can open a session at all:

   • The Host Name field is where you type the name or the IP address of the server you want to connect to.
   • The Connection type field lets you choose what type of connection you want to make.
   • The Port field is where you specify which port number on the server to connect to.

   Perform the following steps if the cluster that you need to access is listed under Saved Sessions:

   1. Select the menu item for the cluster.
   2. Click Load.
   3. Click Open.
2. If you are using SSH to connect to a server for the first time, you see the PuTTY Security Alert message. Click Yes. The command-line window for service is displayed.

   login as: service
   Authenticating with public key "rsa-key-20030213"
   IBM_2145:service>
   
   
   
   
   
   
   
   
   
   
   

3. Type the user name service at the login prompt. When the service prompt is displayed, you can use the CLI to issue commands.
4. Issue a command following the service prompt to display information about the SAN Volume Controller. For example, issue the following command to view the current status of the nodes that are used by the SAN Volume Controller cluster:

   svcinfo lsnode -nohdr -delim :

   The current status of the nodes used by the SAN Volume Controller cluster is displayed.

   login as: service
   Authenticating with public key "rsa-key-20030213"
   IBM_2145:service>svcinfo lsnode -nohdr -delim :
   1:node1:1OL3ANP:50050768010000F6:online:0:io_grp0:no:202378101C0D17A0
   2:node2:1OL3BNZ:5005076801000184:online:0:io_grp0:yes:202378101C0D27AA

   IBM_2145:service>
   
   
   
   
   
   
   
   
   
   
   

5. Issue the following command:

   svcinfo lscluster clustername

   where clustername represents the name of the cluster for which you want to list the details.
