NonStop Operations Guide for H-Series and J-Series RVUs

= SHUTDOWN2, MODE ORDERLY
3. Stop Distributed Systems Management/Software Configuration Manager (DSM/SCM) if it is
running. At a TACL prompt:
a. Type this VOLUME command:
> VOLUME $DSMSCM.ZDSMSCM
b. Stop DSM/SCM:
> RUN STOPSCM
4. Stop communications lines, such as Expand lines.
5. Identify and stop any remaining processes that should be stopped individually:
a. Use the TACL PPD and STATUS commands to help you identify running processes.
b. Use the TACL STOP command to stop running processes.
6. Drain the spooler. The SPOOLCOM SPOOLER DRAIN command stops the spooler in an orderly
manner. It is the only recommended way to stop the spooler. At a TACL prompt:
> SPOOLCOM supervisor-name, SPOOLER, DRAIN
7. Stop the TMF subsystem. At the TACL prompt:
> TMFCOM STOP TMF
8. Refresh the disks to put them in an orderly state before shutdown. Use the SCF CONTROL
DISK, REFRESH command:
> SCF CONTROL DISK $*,REFRESH
9. If the system is a member of a ServerNet cluster (such as a 6770 ServerNet cluster, 6780
ServerNet cluster, or BladeCluster), HP recommends that you first remove the system from the
cluster. To remove the system from the cluster, refer to the ServerNet Cluster 6780 Operations
Guide (for 6780 switches), the ServerNet Cluster Manual (for 6770 switches), or the
BladeCluster Solution Manual (for BladeClusters).
Stopping the System
Stopping a system halts each processor (terminating all processes running in each processor) on
the system in an orderly fashion.
Alerts
Before stopping a system:
• Stop applications, devices, and processes in an orderly fashion. See “Stopping the System”
(page 191).
• To maximize application availability, make stopping the system a planned event whenever
possible.
Halting All Processors Using OSM
To place processors in a halt state and set the status and registers of the processors to an initial
state:
1. Prepare the system by shutting down applications and performing all tasks in “Stopping the
System” (page 191).
2. Log on to the OSM Low-Level Link.
3. On the toolbar, click Processor Status.
