(Optional) Recover Data from the iSCSI Volume to the Target Machine

If you have stored your data in an iSCSI target volume, you can connect to the iSCSI volume and recover data. The iSCSI volume lets you manage data and transfer data over a network.

Follow these steps:

  1. Insert the Arcserve UDP Agent (Linux) Live CD or mount the iso file of the Arcserve UDP Agent (Linux) Live CD into the CD-ROM drive of the target machine.
  2. Boot the target machine from the CD-ROM.
  3. The target machine boots into the Arcserve UDP Agent (Linux) Live CD environment. On the screen, the IP address of the target machine is displayed.
  4. Enter the shell environment of the target machine.
  5. Run the following command to start the iSCSI initiator daemon:

    6. /etc/init.d/iscsid start

  6. Run a discovery script to discover the iSCSI target host.

    7. iscsiadm -m discovery -t sendtargets -p <ISCSI-SERVER-IP-ADDRESS>:<Port_Number>

  7. The default port value of iSCSI target host is 3260.
  8. Make a note of the iSCSI Qualified Name (IQN) of the iSCSI target host found by the discovery script before you manually log into the discovered target.
  9. List the available block device of the target node.

    10. #fdisk -l

  10. Log in to the discovered target.

    11. iscsiadm -m node -T <iSCSI Target IQN name> -p <ISCSI-SERVER-IP-ADDRESS>:<Port_Number> -l

  11. You can see a block device in the /dev directory of the target node.
  12. Run the following command to obtain the new device name:

    13. #fdisk –l

  13. You can see an additional device named /dev/sd<x> on the target node.
  14. For example, consider the name of the device is /dev/sdc. This device name is used to create a partition and a file system in the following steps.
  15. Mount the iSCSI volume using the following commands:

    16. # mkdir /iscsi

    # mount /dev/sdc1 /iscsi

  16. Note: When you specify the session location in the Restore Wizard, you need to select Local and enter the path /iscsi.
  17. Example: <path>/iscsi

The target machine can now connect to the iSCSI volume and can recover data from the iSCSI volume.
