Appendix G ACOS-4 Resource Operation
Guard
It is allowed only for our maintenance personnel to specify ACOS-4 resource settings. If
you need to handle ACOS-4 resources, be sure to ask our maintenance personnel first.
To protect ACOS-4 against system destruction, the work involved in setting the resources used by ACOS-4 is
defined as tasks to be carried out by maintenance personnel. On the other hand, the open system resources are
allowed to be set by general users, giving priority to the freedom of work in such cases as changing the settings.
Note, however, that a mistake or other inappropriate operation that the general user makes when setting the Access
Control in the WWN mode or in the GUI-based Port mode, which has been supported for the disk array which
applies program product “AccessControl” beginning with Version 2.1, can result in the destruction of the ACOS-4
system.
Starting with Version 2.2, a reinforced guard function has been deployed that guards against
Access-Control-related operation’s that can lead to the destruction of the ACOS-4 system. Whenever an
operation related to the ACOS-4 resources is requested, a dialog appears indicating that the operations for the
ACOS-4 resources by general users are restricted and that a consultation with maintenance personnel is required.
