TC GUI reference

As a reference, you can view Device Manager - Storage Navigator windows and fields used for TrueCopy.

Therefore, if you access the secondary site's HDvM - SN server, the GUI displays information for the pair's secondary (remote) system under "Local Storage System", and the GUI identifies the storage system connected to the accessed storage system as the "Remote Storage System".

In this manual, the term "primary storage system" and "primary system" refer to the storage system in which the primary volume (P-VOL) is located, and the terms "secondary storage system" and "secondary system" refer to the storage system in which the secondary volume (S-VOL) is located, unless otherwise noted.

Replication window

Use this window to view information about pairs and pair volumes.

Status

Pair status.

Synchronization Rate (%)

Displays the synchronization rate between the P-VOL and S-VOL:

  • Initial copy progress rate is displayed during the initial copy process.
  • Data synchronization rate of the P-VOL and S-VOL is displayed during pair split.
  • "(Queuing)" is displayed if processing has not started.

For a TC pair, when the local storage system volume is the P-VOL, the percentage is displayed regardless of the pair status. When the local storage system volume is the S-VOL, the percentage is displayed only if the pair status is other than COPY.

(VSP 5000 series) For a TCz pair, when the local storage system volume is the P-VOL, the percentage is displayed regardless of the pair status. When the local storage system volume is the S-VOL, a hyphen (-) is displayed.

Fibre Channel
GUID-DA54AD75-7DA9-4B66-980D-5C3BE199CB63-low.png
For Fibre Channel ports

Item

Description

Port Attribute

Port I/O flow:

  • Target: Receives I/O commands from a host
  • Bidirectional

Port Security

LUN security (Enabled or Disabled)

Port Speed

Transfer speed, in Gbps, for the selected Fibre Channel port.

If Auto is selected, the storage system automatically sets the data transfer speed to 4, 8, 16, or 32 Gbps.

Caution: These cautions must be observed when setting speed on a Fibre Channel port:

  • If a port supports 4, 8, 16 or 32 Gbps, use 4, 8, 16 or 32 Gbps for the port speed, respectively.
  • If the Auto Negotiation setting is required, some links might not be up when the server is restarted. Check the channel lamp. If it is flashing, disconnect the cable, and then reconnect it to recover from the link-down state.
  • If the port speed is set to Auto, some equipment might not be able to transfer data at the maximum speed.
  • When you start a storage system, HBA, or switch, check the host speed displayed in the Port list. If the transfer speed is different from the maximum speed, select the maximum speed from the list on the right, or disconnect, and then reconnect the cable.
  • The available port speed that is specified in Port Speed is limited due to the combination of the type of the Fibre Channel port and the topology that is specified in Connection Type.
  • If the transfer speed of the CHB (FC) port is set to Auto, the data might not be transferred at the maximum speed depending on the connected device. Confirm the transfer speed displayed in Speed in the Ports list when you start up the storage system, HBA, or switch. When the transfer speed is not the maximum speed, select the maximum speed from the list on the right or remove and reinsert the cable.
