Adding Storage Devices

Functions (such as remote replication or snapshot) provided by storage devices are used by eReplication to perform data protection and DR jobs. Before creating protected groups, you need to add storage devices at the production and DR sites to the corresponding site.

Prerequisites

The scenarios of adding storage devices are described in Table 1.

Table 1 Application scenarios of storage devices

Protected Object

Description

  • Oracle
  • IBM DB2
  • Microsoft SQL Server
  • SAP HANA

Adds storage devices associated with databases.

VMware

Adds storage devices associated with VMs.

LUN

Adds associated storage devices.

  • You can connect storage devices to eReplication using MD5 encryption. Note that passwords encrypted based on MD5 may be cracked.
  • You can connect storage devices to eReplication using SHA-256 encryption and fixed salt.

Context

One storage device can be added only to one site on eReplication.

Procedure

  1. On the menu bar, select Resources.
  2. In the navigation tree, select the site where the storage device is to be added.

  3. Click Add Storage Device.

    • Method 1: In the Resource Statistics area, click Add Storage Device.

    • Method 2: In the navigation tree, select Storage. Then click Add Storage Device.

  4. Optional: Select Apply the port, username, and password of the first row to the newly added row.. The system will copy the port number, username, and password of the storage device in the first row to the new row to avoid repeated inputs.
  5. Set parameters for the storage devices to be added as described in Table 2.

    • If only one storage device needs to be added, enter the IP address, port number, username, and password of the storage device.
    • If multiple storage devices need to be added, you need to click Add Row to enter the IP addresses, port numbers, usernames, and passwords of multiple storage devices.
    Table 2 Parameters for adding storage devices

    Parameter

    Description

    Value

    IP Address

    Management IPv4 or IPv6 address of the storage device.

    [Example]

    192.168.10.11

    Port

    Communication port of the storage device.

    • Default port: default management port configured for the storage device before delivery. The system uses this port to communicate with the storage device.
    • Customized port: management port customized for the storage device. The system uses this port to communicate with the storage device.
    • If Default port is selected, the value is automatically configured by the system.
    • If Customized port is selected, the port number is an integer from 1 to 65,535.

    Username

    User name for logging in to the storage device.

    It can be obtained from the storage device administrator.

    NOTE:

    After the password of a storage device is changed, eReplication continuously accesses the storage device. As a result, the storage account is locked. You are advised to create a user only for accessing eReplication on the storage device. The user must have administrator rights and the password never expires. Dorado V3 is used as an example. For details, see Setting User Passwords to Never Expire.

    Password

    Password of the storage device.

    It can be obtained from the storage device administrator.

    If an added storage device does not need to be discovered, click Delete to delete it. The default information row cannot be deleted.

  6. Click OK.

Related Operations

After storage devices are added, you can refresh, modify, and delete information about storage devices. For details about related operations, see Table 3.

Table 3 Related operations

Operation

Description

Implementation

Refreshing information about a storage device

eReplication automatically refreshes information about added storage devices every 12 hours to ensure the information on eReplication is consistent with the actual information. If storage device information is modified, you need to refresh the information in eReplication immediately.

In the row where the storage device resides, click Refresh on the Operation list.

Modifying a storage device's name

Modify the name of the storage device.

In the row where the storage device resides, click More > Modify on the Operation list.

Deleting a storage device

Delete unnecessary storage devices from the site.

In the row where the storage device resides, click More > Delete on the Operation list.

Managing a storage device

Go to the device management page. For details about device management, see the online help.

In the row where the storage device resides, click More > Device Management on the Operation list.
