Initializing the alternate master using SMIT

Edit online

Follow this procedure for initializing the alternate master using SMIT.

In this scenario, master A is already configured as a NIM master, and master B will be initialized as an alternate master.

  1. Insert the AIX Volume 1 media into the appropriate drive of the designated alternate master system (master B).
  2. Enter the SMIT install_latest fast path, to install the bos.sysmgt.nim.master fileset.
  3. Using the LIST option, select /dev/cd0 for the INPUT device or directory for software.
  4. Specify bos.sysmgt.nim.master as the SOFTWARE to install.
  5. Accept the default values for all other fields on this display. After successful completion of this installation, exit SMIT.
  6. To initialize the alternate master (master B) with master A, enter the smit niminit_altmstr fast path on the master B system.
  7. Type the name of master B in the This Machine Name field.
  8. Using the LIST option, select the Primary Network Interface for master B.
  9. Type the host name of master A in the Host Name of Master with which to Initializefield.
  10. Change any other fields as necessary, and press Enter.
  11. On master A, repeat the process by using the smit niminit_altmstr fast path to register master A with master B. You will need to type the name of master A in the Machine field and the host name of master B in the Host Name of Master with which to Initialize.

Consider the following items when you initialize the alternate master from SMIT:

  • The niminit command creates an alternate_master object for the registering system. In this example, master B is defined as an alternate_master object on master A when master B is registered with master A.
  • The niminit command configures the alternate_master object as a NIM master if it is not already configured as one.
  • The niminit command notifies the master that the system is registering with remote access permissions through the nimsh shell. In this example, when master B is registered, master B gives master A remote access permissions.
  • After an alternate master has been added to the NIM environment, clients initialize themselves again to recognize the alternate master. Initializing again gives the alternate master remote access to the clients either through the rsh or nimsh shells. After clients have initialized themselves again, their sync_required attribute is set to no, indicating that they recognize the alternate master.
