Customize Performance Manager to run San Volume Controller cluster data-collection tasks Configuring

Perform this task to provide the the Secure Shell Client (SSH Client) private key from an SSH Client key pair to Performance Manager to enable SAN Volume Controller (SVC) performance data collection. You must also provide the SSH Client public key from the SSH Client key pair to all SVC clusters from which you will do performance data collection.

If you provided the SSH Client private key during the installation of Performance Manager, this task is complete and you do not have to perform this task manually. If you did not provide the SSH Client key at that time or if you want to change the SSH Client key, perform this task.

Steps

Perform the following steps from a Windows system to provide your SSH Client private PuTTY key to Performance Manager:

  1. Identify an SSH Client key pair which you will make available to Performance Manager. The easiest and fastest way to provide Performance Manager with a valid SSH Client key pair is to reuse your SAN Volume Controller Console SSH Client private key which is already working with your SAN Volume Controller clusters. The SSH Client private key, icat.ppk, can be found under the SAN Volume Controller Console CIMOM directory. The default location is:
    c:\Program Files\IBM\svcconsole\cimom\icat.ppk
  2. If you cannot find this key pair, you can create a new PuTTY SSH key pair. The SAN Volume Controller Configuration Guide ("Master Console Overview - Generating an SSH Key Pair using the SSH Client called PuTTY") contains instructions on how to make the PuTTY key pair. You can also use the SSH Client sample key pair provided in the pmgrkey directory discussed in step 4.
  3. Put the SSH Client private key in the Performance Manager directory. PuTTY was installed on your system as a prerequisite to installing Performance Manager. The default PuTTY home directory is c:\Program Files\PuTTY. Look in the PATH environment variable to find the PuTTY directory if it was not installed in a non-default location.
  4. Find (create if absent) a directory named pmgrkey under the PuTTY home directory. Put your PuTTY private key in the pmgrkey directory with the name "icat.ppk".

To store a new SSH public client key on the SAN Volume Controller cluster, perform the following steps:

  1. Start the browser to access the SAN Volume Controller Console, Http://<svccip>:9080/ica, where <svccip> is the IP internet address for the SAN Volume Controller Console.
  2. Log onto the SAN Volume Controller Console.
  3. Select "Clusters" in the left hand frame.
  4. Select the cluster in which you are interested and select "Launch the SAN Volume Controller application" to open a secondary browser window to manage your specific cluster.
  5. Expand "Service and Maintenance" in the left hand frame.
  6. Select "Maintain SSH Keys" to access the panel where you can enter the SSH public key that is to be saved on the cluster.

Before submitting a data collection task you can validate the Performance Manager SSH Client keypair connectivity by manually checking for SSH connectivity from your Performance Manger system to the SAN Volume Controller clusters:

  1. Open a Command Prompt.
  2. Change directory to the PuTTY home directory, the default directory is: C:\Program Files\PuTTY.
  3. Type: plink admin@x.x.x.x -ssh -2 -i pmgrkey\icat.ppk, where x.x.x.x is the IP address of your SAN Volume Controller cluster.
    Note:Note: When you create Performance Manager tasks to do performance collection tasks, you must enter the "admin" user name as the "SVC user name". This is consistent with the network user name you enter for HTTPS access to the SVC cluster. Do not use the MDM super user name.
