Administrator Guide

注: When in Maintenance mode, image expiration fails because the DR Series system is in a read-only state. If this
occurs, the DMA assumes that the backup images have expired. However, the DR Series system administrator may
be unaware that the backup data images still reside on the DR Series system.
Filesystem Check — Unsuccessful: when the Maintenance mode halts at the Completed Generating Report stage, this
indicates that the filesystem check detected some repairable files, and listed them in the Repair Report pane on the
Maintenance Mode page.
To return to the Operational mode, click Confirm Repair Filesystem on the Maintenance Mode page options bar to repair
the files listed in the Repair Report. Confirm Repair Filesystem is the only active option you can select when the progress
bar indicates that some filesystem files are in need of repair.
About the DR Series System Support Mode
Generally, the DR Series system enters its Support mode only because of one of the following reasons:
• The filesystem has encountered an issue that could not be resolved by running the internal Maintenance mode.
• Some system processes failed to start properly.
• The system detected an unsupported configuration.
The Support mode puts the DR Series system into a state in which only the following tasks can be performed:
• Generating a DR Series system diagnostics file. For more information, see Generating a Diagnostics Log File.
• Upgrading the DR Series system software. For more information, see Upgrading the DR Series System Software.
• Installing a license for the data storage expansion shelf enclosure. For more information, see Expansion Shelf
Licenses and Installing an Expansion Shelf.
• Contacting Dell Support for technical assistance. For more information, see Contacting Dell.
注: Dell recommends that you generate a DR Series system diagnostics file whenever the DR Series system is in its
Maintenance or Support modes if one was not automatically generated.
When in the Support mode, the DR Series system displays the following alert message:
The server is currently in Support mode. To continue, you must contact Dell
Support at http://www.support.dell.com or contact your Dell support
representative.
计划 DR Series 系统操作
请记住，在计划关键的 DR Series 系统操作时，最为重要的是确保在适当的时间执行每项操作，以免与其他重
要的系统操作发生重叠或对其造成妨碍。
通过更好地计划系统操作的运行时间，可以优化系统资源，以便实现最佳的 DR Series 系统性能。为此，请为
以下关键系统操作计划安排执行时间：
• 数据插入（它取决于 DMA）
• 复制进程
• 清理器进程（空间回收）
在计划和安排操作时，主要目标是在适当的时间运行清理器和复制操作，以免与其他重要的系统操作发生重叠
或对其造成妨碍。应该确保通过适当的安排和计划，系统可以相互独立地执行每项关键操作。
最佳做法是在非标准工作时间运行这两项操作，以免与其他任何备份或插入操作发生冲突。简言之，通过高效
的计划可以最大限度地利用系统资源。
