SHUTSPM(8)                      Domain/OS BSD                       SHUTSPM(8)




NAME
     shutspm - shut down SPM on a node

SYNOPSIS
     shutspm

DESCRIPTION
     When the server process manager (SPM) runs in control of a node, it waits
     on the eventcount file `node_data/spmshut_ec.  shutspm advances this
     eventcount, causing the SPM to perform an orderly shutdown of the node.

     To shut down the SPM with shutspm, create a remote process (via the crp
     command) on the target node and type shutspm.

     Normally, only system administrators may shut down the SPM using this
     command.  This is because SPM creates the `node_data/spmshut_ec file with
     the following ACL (provided the default file ACL for `node_data gives all
     rights to %.%.%):


     Subject ID          Access Rights


     %.sys_admin.%       prwx-

     %.%.%               -rw--

     This ACL limits shutspm shutdown to accounts with the sys_admin group
     name, but permits any account to delete the spmshut_ec file whenever SPM
     is not using it.  If, however, the default file ACL for `node_data  has
     been changed, SPM creates the eventcount file using that default ACL.
     Note that a subject identifier must have at least r and w rights to shut
     down SPM.

     If the spmshut_ec file already exists when SPM starts up, SPM does not
     change its ACL.

     To prevent SPM from responding to the shutspm command, add the following
     line to the `node_data/startup.spm file:

     no_shutspm


EXAMPLES
     $ crp -on 1fb -login sys_admin


     Create remote process on server node 1fb and log in with the system
     administrator account.  (You'll be prompted for a password.)

     $ shutspm


     Shut down the SPM on server node 1fb.
