DCMI function

This section describes the DCMI function.

DCMI overview

CB 500 supports DCMI (Data Center Manageability Interface) version 1.5. By
issuing DCMI commands (IPMI command-based) from the OS on a server
blade or an external management PC connected by LAN to BMC on a server
blade supporting DCMI, you can manage power and monitor various
environmental values.
To use DCMI, you need to enable the DCMI mode of the server chassis in
advance. Server blades that support DCMI can accept DCMI commands only
when the DCMI mode is enabled. Even if the DCMI mode is enabled, server
blades that do not support DCMI cannot accept DCMI commands.
Note:
• You cannot enable both DCMI and APC (Accurate Power Control) at the
same time. When you enable the DCMI mode, APC automatically becomes
disabled and you cannot change settings related to APC.
• You can enable or disable the DCMI mode in the following cases:
¢
¢
• If you enable the DCMI mode, the APC settings are reset. Similarly, when
you disable the DCMI mode, the DCMI settings are reset.
• You can use DCMI and EPC simultaneously. If the power supply becomes
insufficient because of a power failure, power capping by EPC is prioritized
for continuous operation of the equipment.

Server blades that support DCMI

To use DCMI, server blades must support it. For details of servers supporting
DCMI, see the Hitachi Compute Blade 500 Series System Overview Guide.

Setting the DCMI mode

1 Switch to the DCMI mode.
.
To set the DCMI mode, use either the Web console or CLI console.
When you change the settings that switch the DCMI mode, server blades
that support DCMI are automatically re-initialized.

All blades in a server chassis have been initialized.
The main power of blades supporting DCMI within the server chassis
is off.
