HP NetServer AA Shutting Down the System There are various methods to shut down the system, power down the system, or remove a component from the array. It is imperative that the administrator understands what the goal is before issuing a command to the system that removes the component or shuts down the system. Keeping in mind that the HPAA system is a high availability solution capable of running for a year with virtually no downtime, the administrator can take action that diminishes the systems fault-tolerant status, so the utmost caution should be taken. There are generally two methods to change the status of a component: (1) issue a command at the command prompt using the MTCCONS.exe comand, or (2) use the "Display and Control" window in the Marathon Manager Utility. The following actions will degrade the redundancy of the array or make the array unavailable to client network access: • Removing or Disabling a CE • Removing or Disabling an IOP • Issuing a CE Operating System Shutdown Command • Issuing an IOP Shutdown Command • Issuing a "server" Shutdown Command • Issuing a "server" Reboot Command NOTE There is a major difference between a shutdown and a disable command.

Shutting Down the System
There are various methods to shut down the system, power down the
system, or remove a component from the array.
It is imperative that
the administrator understands what the goal is before issuing a
command to the system that removes the component or shuts down
the system.
Keeping in mind that the HPAA system is a high
availability solution capable of running for a year with virtually no
downtime, the administrator can take action that diminishes the
systems fault-tolerant status, so the utmost caution should be taken.
There are generally two methods to change the status of a
component: (1) issue a command at the command prompt using the
MTCCONS.exe comand, or (2) use the “Display and Control”
window in the Marathon Manager Utility.
The following actions will degrade the redundancy of the array or
make the array unavailable to client network access:
•
Removing or Disabling a CE
•
Removing or Disabling an IOP
•
Issuing a CE Operating System Shutdown Command
•
Issuing an IOP Shutdown Command
•
Issuing a “server” Shutdown Command
•
Issuing a “server” Reboot Command
NOTE
There is a major difference between a shutdown and a disable
command.
This will be explained throughout the remainder of
this chapter.
MTCCONS.exe
Upon installing the AA 4000 software, the MTCCONS.exe utility is
made available at the Windows NT command prompt.
The utility
allows for AA 4000 commands to be executed from an MS-DOS
window or a Windows NT command prompt window.
The primary
reason for using MTCCONS (Marathon Manager console
commands) is to execute scripts for system validation (test) or
system management.
When using MTCCONS, you must enter the
exact command syntax and any required parameters. Each command
has the following components: ‘Prefix’, ‘Target’, ‘Verb’, ‘Operation
type’, ‘Executed from’ and any associated ‘Parameters’.
