4.9.1 accopy query (Copy Session Information Display Command)

NAME

accopy query - Display copy session information

SYNOPSIS

DESCRIPTION

This command displays the status of the copy sessions being performed in the specified ETERNUS Disk storage system.
This command also targets the copy sessions that are started by software other than AdvancedCopy Manager.

OPTIONS

-a diskArrayName

This option specifies the name of ETERNUS Disk storage system for which the execution status of copy sessions is displayed.

-type {local | remote | odx | vvol | all}

This option specifies the type of copy sessions to display.

  • local: Displays only OPC, QuickOPC, EC, SnapOPC, SnapOPC+, monitor sessions, and Extended Copy.

  • remote: Displays only REC sessions.

  • odx: Displays ODX.

  • vvol: Displays VVOL sessions.

  • all: Displays all sessions.

-tfoinfo

This option is specified when displaying information about the Storage Cluster Continuous Copy function.
Refer to the EXAMPLES table for items displayed when this option is specified.

-sa srcDiskArrayName -ta dstDiskArrayName

This option specifies the display of information for all REC sessions set up from the device specified with the -sa option towards the device specified with the -ta option.
Either srcDiskArrayName or dstDiskArrayName must match with the ETERNUS name specified to the -a option.
If specifying a device other than a management device for AdvancedCopy Manager CCM or Express, specify the Box ID (40 characters) instead of the ETERNUS name of AdvancedCopy Manager CCM or Express.

-xml

This option specifies when displaying by the XML format.

EXIT STATUS

=0: Completed successfully
>0: Terminated abnormally

EXAMPLES

The following table shows the meanings of the information displayed.

Title

Explanation

Source

Displays the logical volume for the copy source.

  • When the copy is executed in logical volume units:

    • ETERNUS name or Box ID

    • Logical volume number

  • When the copy is executed in extent units:

    • ETERNUS name or Box ID

    • Logical volume number[addr=copy_start_location,size=copy_size]

The logical volume number, copy start location and copy size are displayed in hexadecimal.

<=>

Displays the copy direction.

  • "==>" (Copying from the source to the target) is always displayed.

Target

Displays the logical volume for the copy destination.

  • When the copy is executed in logical volume units:

    • ETERNUS name or Box ID

    • Logical volume number

  • When the copy is executed in extent units:

    • ETERNUS name or Box ID

    • Logical volume number[addr=copy_start_location,size=copy_size]

The logical volume number, copy start location and copy size are displayed in hexadecimal.

When Copy Type column is "Estimate", "----" is displayed.

SID(RSID)

Displays the session ID, REC session ID, and VVOL session ID in "x(y)" format.

  • For OPC, QuickOPC, EC, SnapOPC, SnapOPC+, Extended Copy, and Offloaded Data Transfer:

    • x: Session ID

    • y: ----

  • For REC:

    • x: Session ID (the ID for the session in the device specified with the -a option)

    • y: REC session ID (the ID for the session in the copy destination device specified with the -a option)

  • For VVOL session:

    • x: VVOL session ID (may overlap with the Session ID)

    • y: ----

Copy Type

Displays the copy type.

  • OPC: The OPC is executing.

  • QuickOPC: The QuickOPC is executing.

  • SnapOPCP: The SnapOPC+ or SnapOPC is executing.

  • EC: The EC is executing.

  • REC: The REC is executing.

  • Estimate: monitor session is executing.

  • Xcopy: The Extended Copy is executing.

  • ODX: Offloaded Data Transfer is executing.

  • VVOL-Snapshot, VVOL-Clone, VVOL-Fastclone, VVOL-Revert, VVOL-CopyDiffs: VVOL session is executing.

Copy Status

Displays the copy execution status.

  • Starting: The copy is starting up.

  • Executing: The copy is executing.

  • Suspend: The EC or REC is suspended.

  • Error Suspend: An error has occurred, preventing the copy process from continuing.

  • Hardware Suspend: The copy is temporarily stopped due to a path error between devices. (If using REC)

  • Hardware Suspend(Use REC DISK): The copy is using the REC Disk buffer due to a path error between devices. (If using REC)

  • Hardware Suspend(Use REC BUFFER): The copy is doing REC buffering due to a path error between devices. (If using REC)

"EC Hardware suspend (Use REC DISK)" and "EC Hardware suspend (Use REC BUFFER)" is displayed in the following circumstance.

  • If the device specified with the -a option for the acgroup create command has become the REC copy source device

Copy Phase

Displays the current phase.

  • Readying: Concurrent OPC is defined.

  • Copying: Copy processing is executing.

  • Paired: The copy is in the equivalency maintenance state.

  • Tracking: QuickOPC copy processing has completed, and tracking is in progress.

  • Copying/Tracking: Both QuickOPC copy processing and tracking are in progress.

  • N/A: Copy processing has not been performed.

Progress

Displays the progress of copy processes as a percentage. The "N/A" is displayed in the following case.

  • When Copy Type column is SnapOPCP or Estimate

  • When the copy is executed in logical volume units on the following storage devices:

    • ETERNUS DX80 S2 (for earlier than V10L30 firmware)

    • ETERNUS DX90 S2 (for earlier than V10L30 firmware)

    • ETERNUS DX400 S2 series (for earlier than V10L30 firmware)

    • ETERNUS DX8000 S2 series (for earlier than V10L30 firmware)

Copied Block

Displays the number of blocks that have been copied.
If Copy Phase column displays "Tracking", it displays the number of blocks that have not been updated after the last execution of the logical copy.

Total Block

Displays the number of total blocks.
When the copy is executed in logical volume units, it is displayed "N/A".

Operation Date

If a copy session exists, it displays the date for when the EC session state transitions indicated below last occurred (last execution date) in a "yyyy/mm/dd hh:mm:ss" format.
The displaying of the date is performed on the basis of the target device's time zone.

  • For OPC, QuickOPC, Extended Copy, Offloaded Data Transfer, and VVOL session:

    • Starting logical copy

    • State transition to error suspend (Copy Status column displays "Error Suspend")

  • For SnapOPC+ and SnapOPC:

    • Starting logical copy

    • State transition to error suspend (Copy Status column displays "Error Suspend")

  • For EC:

    • Suspend

    • Concurrent suspend

    • State transition to error suspend (Copy Status column displays "Error Suspend")

  • For REC:

    • Start of REC by initial copy skip function

    • Suspend

      • If a forced suspension was performed to an REC session in a Hardware suspend status, the last execution date is initialized as "----/--/-- --:--:--."

      • If a forced suspension was performed to an REC session with the execution of a copy in progress, the last execution date is not updated.

    • Concurrent suspend
      During a not-yet transmitted suspension, the last execution date is not updated.

    • State transition to an Error suspend (Copy Status column displays "Error Suspend")

    • State transition to a Hardware suspend (Copy Status column displays "Hardware Suspend")

If any of the following conditions apply, the date is displayed as "----/--/-- --:--:--."

  • If an EC/REC initial copy was started from a status of a copy session not existing

  • If the REC session underwent an automatic recovery from a Hardware suspend status (Copy Status column displays "Hardware Suspend")

  • If using a device for which the last execution date recording function is not supported (ETERNUS DX60 S2)

Active/Standby

This is displayed when the -tfoinfo option is specified.
If the Storage Cluster Continuous Copy function is used, the TFO status is displayed.

  • Active: An Active-Side Continuous Copy Session.

  • Standby: A Standby-Side Continuous Copy Session.

  • ???: Failed to get the TFO status.

  • ----: The Storage Cluster Continuous Copy function is not used.

TFO Info

This is displayed when the -tfoinfo option is specified.
If the Storage Cluster Continuous Copy function is used, the Storage Cluster Continuous Copy session status is displayed.

  • normal: The Storage Cluster Continuous Copy sessions are synchronized on the Primary Storage and Secondary Storage.

  • unpaired: The Storage Cluster Continuous Copy sessions are not synchronized on the Primary Storage and Secondary Storage.

  • ???: Failed to get the TFO status.
