Start/End Maintenance

Overview

This function prepares a suitable status of the storage system for maintenance, and notifies the storage system that maintenance operation has started or ended.

When a start maintenance operation is being performed, the operation mode of the storage system is changed to "Maintenance Mode". In addition, reporting of Maintenance Mode sense information and SNMP notifications are suppressed.

When using the Remote Support function, this function notifies the REMCS center of the starting or ending of a maintenance operation by sending an event. While the operation mode is "Maintenance Mode", the Remote Support (REMCS) status is changed from "Operating" to "Stopping". In addition, automatic notification of storage system failures to the REMCS center is suppressed.

When performing the end maintenance operation, the operation mode is changed to "Normal", and the Remote Support (REMCS) function is automatically resumed.

The start maintenance operation needs to be performed when the following functions are used:

  • Firmware maintenance

  • Hot preventive maintenance

  • Adding a component in hot mode

  • Removing a component in hot mode

Make sure to perform the end maintenance operation after maintenance operation is complete.

Caution

  • Force disable and force enable can be performed when the start maintenance operation has not been performed. However, it is recommended to perform the start maintenance operation.

  • If the Remote Support function is "Stopping" or the Remote Support setting is not configured, this function does not notify the REMCS center of the start or end of maintenance.

  • If the communication between storage system and REMCS center is not established, the notification fails. However, the start/end of maintenance operation is performed irrespectively.

  • If three hours elapses without any maintenance operation being performed after the start maintenance operation is executed, the maintenance mode is automatically canceled.

Note

  • If maintenance operations can be performed, "Maintenance Mode" is displayed on the Web GUI screen header.

  • Under the following conditions, maintenance operations can be performed without performing start maintenance operations.

    • When using the ETERNUS DX60 S5, the ETERNUS DX100 S5/DX200 S5, or the ETERNUS AF150 S3/AF250 S3, a user with the "Storage Management" policy can perform the [Add Drive Enclosure] function.

    • When the minimum port type CA (*1) is installed in the ETERNUS DX60 S5/DX100 S5 CM, a user with the "Storage Management" policy can perform the [Add Channel Adapter Port] function.

      *1  :  CAs with the minimum number of ports. 1-port types and 2-port types are available.

    • A user with the "Firmware Management" policy can use the [Apply Controller Firmware] function in simple mode.

  • After the maintenance mode is changed from "Maintenance Mode" to "Normal", the [Clear Sense Data] function and the [Automatic Log Transmission] function (when using REMCS) are automatically started.
