Implement Logical Block Protection

Logical Block Protection (LBP) is functionality offered by manufacturers of stand-alone tape drives, such as IBM and HP, that lets Arcserve Backup detect read and write errors that occur on drives under the following conditions:

When an error occurs, the drive reports a SCSI error in the Tape Engine log file and the backup will fail.

The Arcserve Backup implementation of LBP does not support the following backups:

To implement LBP, you can create the registry key described in the following procedure. The registry entry can be created under the DEVICE<#> key in the registry for the stand-alone tape drive.

Follow these steps:

  1. Log in to the Arcserve Backup server
  2. Open the following registry key:
    HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\Base\TapeEngine\DEVICE<#>
    

    Note: DEVICE# represents the number of the device where you want to implement LBP.

  3. Create the following DWORD:
    LBP
    
  4. Set the DWORD value of LBP to 1 and save the changes.

    Note: To disable LBP, set the DWORD value of LBP to 0.
