MediaAgent Properties (General)

Use this dialog box to view or change the properties of a MediaAgent.

Names
  • MediaAgent Name

    Displays the display name of the MediaAgent in the CommCell Browser.

  • Host Name

    Displays the full interface name of the MediaAgent computer.

  • CS Host Name

    Displays the full interface name of the CommServe computer. This name is used by the MediaAgent to communicate with the CommServe.

  • Physical/Virtual

    Displays whether the MediaAgent software is installed on the Physical or Virtual computer. (Applies only when the software is installed in a clustered environment.)

  • Active Physical Node

    Displays the MediaAgent Name of the active node. (Applies to MediaAgents in a clustered environment.)

  • Edit

    Click to specify a different Client Name, Host Name and/or CS HostName.

Host Information
  • Host OS

    Displays the operating system of the host machine in which the MediaAgent is installed.

  • Platform

    Displays the processor platform that runs the computer.

  • Description

    Use the space to add MediaAgent-specific information, relevant to your environment.

  • NDMP Properties

    Indicates whether the MediaAgent is installed with NDMP Remote Server. NDMP Remote Server is installed automatically with the MediaAgent software.

Maximum number of parallel data transfer operations

  • Restrict to

    Select how many number of concurrent read/write operations need to be established to the MediaAgent.

    The default number of concurrent read/write operations to a MediaAgent is 25. This value can be set between 1 and 75.

    If Optimize for Concurrent LAN Backup option is enabled in the MediaAgent Properties - Control tab, then the default value is set to 100 and this value can be set to a maximum of 500.

Data Integrity Validation

  • Validation on Media

    When selected, validates the integrity of data stored in the media, during data recovery operations.

  • Validation on Network

    When selected, validates the integrity of data transferred over the network during data protection operations.

MediaAgent Properties (Control)

Use this dialog box to establish the control related options for a MediaAgent.

Enable MediaAgent

Specifies whether the MediaAgent is online or offline. Select this option to bring the MediaAgent online and make it available for use. Clear this option to take the MediaAgent offline. When a MediaAgent is offline, the libraries and drives controlled by the MediaAgent are inaccessible to the CommCell components.

The MediaAgent's enable status reflects its logical availability in the CommCell;  it does not indicate hardware, software or communication failure.

Status

Displays the status of the MediaAgent. (Online/Offline).

Offline Reason

Displays the offline reason, when the Status of the MediaAgent is displayed as Offline.

Mark MediaAgent Offline for Maintenance

Specifies whether the MediaAgent is available for data protection, data recovery and auxiliary copy operations.

When selected, the MediaAgent will be unavailable for data protection, data recovery or auxiliary copy operations. However, the MediaAgent will be available to perform other administrative tasks on the devices attached to the MediaAgent, such as Full Scan, Drive Cleaning, etc.

This option is useful when you wish to perform administrative or maintenance related tasks on the devices attached to the MediaAgent.

Automatically detect WORM Tape Media

Specifies whether the MediaAgent must automatically detect a WORM media when it is used in a drive. Enable this option if you plan to use WORM media in the libraries attached to the MediaAgent.

Data Transfer

  • Optimize for concurrent LAN backups

    This option can be enabled when the MediaAgent is used for concurrent data protection operations from a large number of clients. For example, if you have 25 clients concurrently using the MediaAgent for 50 or more data transfer streams in a specific operation window, it is recommended that you enable this option. Enabling this option will help to optimize the Operating System resources on the MediaAgent.

    For more information, see MediaAgents - Supported Features, Agents and Devices.

Device Detection

  • Auto Update SCSI ID during live operation

    Specifies whether the MediaAgent software will automatically update the SCSI ID during a load/unload/read/write operation, if there are issues relating to access path mismatch or HBA fail over.

    SCSI/SAN device scan interval (n) hours(s)

    Specifies the time interval after which successive SCSI updates can be run on the MediaAgent when a failure is encountered during mount/unmount and read/write operations.

  • Mark drive inaccessible on error and perform status check according to device scan interval

    Specifies whether the drive controller is marked offline if the MediaAgent is not able to access the device during mount operations. The software automatically scans the devices and re-enables the drive controller when it becomes accessible. Note that if multiple MediaAgents access the drive, the drive would continue to be available to the other MediaAgents accessing the drive.

    See MediaAgent Properties in Books Online for detailed information on this option.

Use Native device driver for data transfer for tape media

This option is available only in Unix MediaAgents. Indicates whether the MediaAgent will use the pass-through drivers (provided by the MediaAgent software) or the native driver to communicate with tape devices. Select this option to use the native driver.

Send pass-through commands to Atape on AIX

Option to allow MediaAgent to send pass-through commands to Atape device drivers.

Device access using pass-through driver on Linux

Option to ensure that no other process can access the tape device while SnapProtect processes have the device node open.

Enable retry on network errors

When enabled, the Robust Network Layer feature is enabled allowing the Job Manager to continuously check for network connectivity when loss of connectivity is detected.

  • Retry Frequency (seconds):

    The interval (in seconds) at which the Job Manager will continuously check for network connectivity.

  • Retry Count:

    The number of times the Job Manager will check for network connectivity.

MediaAgent Properties (Associated Storage Policies)

Use this dialog box to identify the storage policies and the storage policy copies accessing the MediaAgent. The following information is displayed for each storage policy:

  • Storage Policy

    The name of the storage policy accessing the MediaAgent.

  • Copy

    The name of the storage policy copy accessing the MediaAgent.

  • Primary Copy

    Indicates whether this storage policy copy is the primary copy or not. (Yes/No)

  • MediaAgent in Default Datapath

    Indicates whether the MediaAgent is established as the default datapath in the storage policy copy. (Yes/No)
