How Device Replacement Works

Situations may arise that require you to repair or replace a device that is connected directly to your CA ARCserve Backup server (for example, a single-drive library, tape drive, CDROM, and so on).

When you replace a device, CA ARCserve Backup demonstrates the following behavior:

• After you replace the device with a device that is different from the original device and start the Tape Engine, CA ARCserve Backup assumes that the device is a new device and creates a new device group for the device. Since the replacement device is not associated with the original device group, jobs associated with the original device group will fail.

  To remedy the failed jobs, you must reconfigure the jobs associated with the original device group and then resubmit the jobs.

• After you replace the device with a device that is the same as the original device and start the Tape Engine, CA ARCserve Backup assigns the device to the device group where the original device was assigned.

  This behavior ensures that jobs associated with the original device group do not fail.

  Limitations:

  • The replacement device must be a product from the same manufacturer as the original device.
  • The replacement device must be the same type of device as the original device (for example, a single-drive library, a tape drive, and so on).
  • The replacement device must be connected to the same adapter and channel as the original device.
  • The original device must not be assigned to a RAID device group.
  • The CA ARCserve Backup server, where the original device is connected, must not be a member of a SAN domain.
