Administrator Guide

NOTA: 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.
NOTA: 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.
Programación de operaciones del sistema DR Series
Lo más importante que debe recordar al programar operaciones críticas del sistema DR Series es que desea
asegurarse de que realiza cada una de estas operaciones a la vez cuando no solapen ni interfieran con la ejecución de
ninguna otra operación clave del sistema.
Mediante una mejor programación al ejecutar operaciones del sistema, podrá optimizar los recursos del sistema y
conseguir el mejor rendimiento posible del sistema DR Series. Para ello, planifique y programe períodos de tiempo en
los que realizar las siguientes operaciones críticas del sistema:
• Incorporación de datos (que dependen de las DMA)
• Proceso de Replicación
• Proceso de Limpieza (reclamación de espacio)
El principal objetivo al planificar y programar operaciones es ejecutar las operaciones de Cleaner (Limpieza) y de
Replication (Replicación) en momentos en los que no solapen ni interfieran con otras operaciones importantes del
sistema. Debe asegurarse de que, programando y planificando correctamente, su sistema pueda realizar estas
operaciones clave con independencia entre sí.
