halogin username [password]
will store the password for you (in encrypted form) so you don't need to authenticate each time to run a command

------------------------------
The halogin command line utility provides users the means to authenticate themselves in VCS cluster environments, which may be secure or non-secure. A secure cluster uses Symantec Product Authentication Service utilities, while a non-secure cluster does not.
Once authenticated on a host, VCS grants users authorization to use VCS commands at a predetermined privilege level. The privilege level specifies that a VCS user can perform certain operations (read, write, or execute) on certain objects (systems, groups, or resources).
The halogin command stores the encrypted authentication information in the user's local home directory. The user may enter subsequent commands without having to login and enter a password until the credential expires.
