About full/background bind

When binding RAID disks, you can choose to do either a full bind or a background bind. Background bind is recommended. These binding processes are described as follows:

  • Full bind — During this process, the K2 SAN must be in the offline mode. While the full bind process is underway, disks are not available for data access of any kind. On a large SAN, the full bind process can take many hours, so you should plan ahead for this process. For example, binding 750 Gig SATA drives can take up to 3 days.
  • Background bind — During this process, the K2 SAN can be in a restricted online mode. Disks are available for data access, but the overall performance of the RAID storage is significantly reduced. While the background bind process is underway, you can initiate media access on your SAN for limited testing of operations, such as record, play, and transfer, but do not run media access at full bandwidth. The background bind process is useful when doing initial system installation and configuration, as it does not require the long wait time required for full bind. You can have RAID disks binding while you move on to other tasks that require RAID media access.

With either type of binding process, you should bind multiple RANKs simultaneously, to reduce the overall time required to bind disks.
