Viewing HyperMetro Information

Viewing HyperMetro Information

Through this operation, you can view information about a HyperMetro including its basic information and HyperMetro pair information, so that you can effectively monitor the operating status of the HyperMetro.

Context

  • On the HyperMetro management page, you can click Refresh to refresh HyperMetro information.
  • On the HyperMetro management page, click Keyword to search for keywords that are required for HyperMetro information viewing.
  • On the HyperMetro management page, click and select HyperMetro information that you want to view.

Procedure

  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperMetro > HyperMetro Pair.
  3. Click the HyperMetro Pair tab.

    The HyperMetro Pair management page is displayed.

  4. View the basic information about a HyperMetro. Table 3-1 describes related parameters.

    Table 3-1 HyperMetro parameters

    Parameter

    Description

    Example Value

    Local Resource Name

    Name of a local resource.

    None

    Local Resource ID

    ID of a local resource.

    None

    Remote Resource Name

    Name of a remote resource.

    None

    Remote Resource ID

    ID of a remote resource.

    None

    Pair ID

    A pair of IDs of local and remote resources in a HyperMetro.

    None

    Pair Health Status

    Displays whether a pair of local and remote resources in a HyperMetro are healthy. Possible values can be Normal and Fault.

    [Example]

    Normal

    Pair Running Status

    Running status of a pair of local and remote resources in a HyperMetro. Possible values can be Normal, To be synchronized, Paused, Synchronizing, Force Start, and Invalid.

    [Example]

    Normal

    Time Remaining for Synchronization

    Time required for synchronization to complete.

    NOTE:

    Some product models and file systems do not support this parameter.

    [Example]

    00:01:29

    Link Status

    Status of a link connected to a HyperMetro.

    [Example]

    Connected

    Configuration Status

    Whether primary and secondary site configurations are synchronized. The value can be Synchronizing, Normal, or To Be Synchronized.

    Because SAN HyperMetro does not support Configuration Status, -- is displayed in the Configuration Status column.

    [Example]

    Normal

    HyperMetro Consistency Group

    Name of the owning consistency group of the HyperMetro pair.

    [Example]

    ConsistentGroup001

    Local Resource Role

    Whether the local resource is provided by the preferred site.

    [Example]

    Preferred

    Activation Status

    Activation status of site. The value can be Active or Passive.

    [Example]

    Active

    Recovery Policy

    A recovery policy supports the following recovery modes:

    • Manual: If a HyperMetro pair is in the To be synchronized state, management and maintenance personnel need to manually perform the Synchronize operation on the HyperMetro pair based on site requirements, so that data synchronization can be performed between the local and remote resources.
    • Automatic: If a HyperMetro pair is in the Synchronizing state, the system automatically and incrementally synchronizes differential data from the primary resource to the secondary resource based on site requirements.

    [Example]

    Automatic

    Owning HyperMetro Domain

    HyperMetro domain to which a HyperMetro belongs.

    [Example]

    domain01

    Local Resource Data Status

    Data status of a local resource.

    [Example]

    Consistent

    Remote Resource Data Status

    Data status of a remote resource.

    [Example]

    Consistent

    Local Resource Host Access Status

    Host access status of a local resource.

    [Example]

    Read-Write

    Remote Resource Host Access Status

    Host access status of a remote resource.

    [Example]

    Read-Write

    Isolation Switch

    After the Isolation Switch is turned on, the system will suspend the HyperMetro pair when the difference between the write I/O latency of the two storage arrays is greater than the isolation switch. The storage array with the longer write I/O latency will stop providing services.

    [Example]

    Disabled

    Isolation Threshold (ms)

    Write I/O latency difference between the host and HyperMetro storage arrays.

    [Value range]

    The value must be an integer from 10 to 30000. The unit is millisecond.

    Data Synchronization Direction

    Data synchronization direction. Possible values are Local to Remote and Remote to Local.

    [Example]

    Local to Remote

  5. Click a HyperMetro whose information you want to view and view its HyperMetro pair information in the lower area of the page. Table 3-2 describes the related parameters.

    Table 3-2 HyperMetro pair parameters

    Parameter

    Description

    Example Value

    Local Device

    Name of a local device.

    None

    Local Resource

    Name of the local resource.

    None

    Remote Resource

    Name of the remote resource.

    None

    Remote Device

    Name of a remote device.

    None

    Recovery Policy

    A recovery policy determines whether the system automatically synchronizes data after a HyperMetro fault is rectified.

    • Automatic: The system automatically synchronizes data.
    • Manual: The synchronization operation must be performed manually.

    [Example]

    Automatic

    Speed

    Speed of data synchronization between the primary resource and secondary resource. Possible values are Low, Medium, High, and Highest.

    [Example]

    High

    Start Time

    Time when data synchronization for a HyperMetro starts.

    [Format]

    YYYY-MM-DD hh:mm:ss UTC+hh:mm

    [Example]

    2014-05-30 16:51:32 UTC+08:00

    End Time

    Time when data synchronization for a HyperMetro ends.

    [Format]

    YYYY-MM-DD hh:mm:ss UTC+hh:mm

    [Example]

    2014-05-30 20:51:32 UTC+08:00

    Isolation Switch

    After the Isolation Switch is turned on, the system will suspend the HyperMetro pair when the difference between the write I/O latency of the two storage arrays is greater than the isolation switch. The storage array with the longer write I/O latency will stop providing services.

    [Example]

    Enabled

    Isolation Threshold (ms)

    Write I/O latency difference between the host and HyperMetro storage arrays.

    [Value range]

    The value must be an integer from 10 to 30000. The unit is millisecond.

    Time Remaining for Synchronization

    Time required for synchronization to complete.

    NOTE:

    Some product models and file systems do not support this parameter.
