ACP

How Data ONTAP uses ACP to increase storage availability

ACP, or Alternate Control Path, is a protocol that enables Data ONTAP to manage and control the DS4243 disk shelf storage subsystem. It uses a separate network (alternate path) from the data path, so management communication is not dependent on the data path's being intact and available.

You do not need to actively manage the DS4243 storage subsystem. Data ONTAP automatically monitors and manages the subsystem without operator intervention. However, you must provide the required physical connectivity and configuration parameters to enable the ACP functionality.

Note: You can install DS4243 disk shelves without configuring ACP. However, for maximum storage availability and stability, you should always have ACP configured and enabled.

After you enable ACP, you can use the storage show acp and acpadmin list all commands to display information about your ACP subsystem.

Service Processor

A Service Processor (SP) provides remote management capabilities, including console redirection, logging and power control. It also extends AutoSupport by sending additional system event alerts. For example, the SP monitors the system temperatures, voltages, currents, and fan speeds. When an environmental sensor has reached an abnormal condition, the SP logs the abnormal readings, notifies Data ONTAP of the issue, and sends alerts and 'down system' notifications as necessary through an AutoSupport message, regardless of whether the storage system can send AutoSupport messages.

The SP is an integral, behind-the-scenes part of NetApp storage system products, starting with the 32xx Series.

So, for storage systems with the SP, there are two additional types of AutoSupport messages—SP-generated AutoSupport messages about the storage system, and storage system-generated AutoSupport messages about the SP.

SP-generated AutoSupport messages include the following information:

• In the subject line—A notification from the SP of the storage system, listing the system condition or event that caused the AutoSupport message and the log level.
• In the message body—The SP configuration and version information, the storage system ID, serial number, model, and host name.
• In the attachments—The system event logs, the system sensor state as determined by the SP, and the console logs. (The console logs are omitted if the autosupport.content option is set to minimal.)
