Adding HMC Dynamic Scopes

Edit online

To add an HMC dynamic scope set, specify the IP address or host name of a single HMC along with a single credential for accessing the HMC. If the user wants to add multiple HMCs, the IP address of the redundant HMC can be added later by editing the HMC dynamic scope. To discover IBM power systems (AIX, Linux, and VIOS) managed by HMC, credentials of the respective LPARs can be added as part of creation or edit of HMC dynamic scope sets. After the HMC dynamic scope set is created, it can be edited to define additional HMC IP addresses or host names, a range of IP addresses, or network or subnet.

About this task

To add a scope set, follow these steps:

Procedure

  1. In the navigation pane, click Discovery Scopes > HMC Dynamic Scopes. To define a new HMC dynamic scope set, click Add New Scope Set.
    The HMC Dynamic Scopes page is displayed.
    Figure 1. Add New Scope Set
    Add HMC Dynamic Scope Set
  2. In the Discovery Scope Set pane, enter a unique name in the Scope set name field.
  3. In the HMC Dynamic Scope Set pane, specify one of the following options in the Select Discovery Option pane:

    • Single IP address or Host

    For IP address, enter the IP address or host name.

    • Range of IP addresses

    For Describe Address Range, enter the starting IP address, ending IP address, and optionally, a description in the fields provided.

    • Network or Subnet

    For Describe Network or Subnet, enter the IP address, mask, and optionally, a description in the fields provided.

  4. In the Enter Access Information for HMC pane, enter the following details -
    1. Enter the Credential name
    2. Select the Authentication type
      • Password - Uses the provided password.
      • PKI - Uses SSH key that is associated with the specific scope set.
    3. Enter the User name that is used to authenticate with the HMC.
    4. When Authentication type is Password, enter the Password and Confirm Password.
    5. When Authentication type is PKI, enter the Passphrase and Confirm Passphrase if the SSH key is encrypted. If the SSH key is not encrypted, leave these two fields blank.
    6. If Authentication type is PKI, click Drag and drop SSH key file or click to upload file uploader to select the private key file, or drag and drop the private key file into the file uploader area. You must externally deploy the public key on the HMC.
    7. Optional: Click Test Credential to test the credentials of the target HMC.
  5. In the LPARs pane, select which LPAR types (AIX, Linux, VIOS) to include in the dynamic discovery.
  6. If you select any of the LPAR types (AIX, Linux™, VIOS), enter the respective access information.
    Figure 2. Example: Enter Access Information for Linux LPARs
    Enter Access Information
    1. Enter the Credential name.
    2. Select the Authentication type
      • Password - Uses the provided password.
      • PKI - Uses SSH key that is associated with the specific scope set.
    3. Enter the User name that is used to authenticate to the respective LPAR.
    4. When Authentication type is Password, enter the Password and Confirm Password.
    5. When Authentication type is PKI, enter the Passphrase and Confirm Passphrase if the SSH key is encrypted. If the SSH key is not encrypted, leave these two fields blank.
    6. If Authentication type is PKI, click Drag and drop SSH key file or click to upload file uploader to select the private key file, or drag and drop the private key file into the file uploader area. You must externally deploy the public key on each LPAR.
    7. Optional: Enter the IP address of an LPAR managed by this HMC and click Test Credential to test the credentials.
  7. Click Save to save the HMC dynamic scope set.
