         ---- Basic System Configuration Dialog ----

This setup utility will guide you through the basic configuration of

the system. Setup configures only enough connectivity for management

of the system.

*Note: setup is mainly used for configuring the system initially,

when no configuration is present. So setup always assumes system

defaults and not the current system configuration values.

Press Enter at anytime to skip a dialog. Use ctrl-c at anytime

to skip the remaining dialogs.

Would you like to enter the basic configuration dialog (yes/no):

This example shows the HA role as secondary. 

Enter HA role[standalone/primary/secondary]: secondary

  Setting HA role to secondary will cause a system reboot. Are you sure (yes/no) ? :

Step 15 Do one of the following:

•If you are setting up the primary/active VSM, go to Step 18.

•If you are setting up the secondary/standby VSM, then continue with the next step.

Step 16 If you have set up the VSM virtual machine (VM) to boot from the CD-ROM, and are installing the secondary VSM from the ISO image attached to your CD-ROM, remove the virtual CD-ROM now so that the VSM does not boot from the CD.

This step is necessary if you have set up the VSM VM to boot from the CD-ROM before the hard drive.

Step 17 If you are setting up the secondary/standby VSM, when prompted to reboot the VSM, answer yes.

The secondary VSM VM is rebooted and brought up in standby mode.

The password on the secondary VSM is synchronized with the password on the active/primary VSM.

Any configuration made on the active/primary VSM is now automatically synchronized with the standby.
