Machine Administration Guide 2.6

B.1 Outline of disk drive replacement

Disk drive replacement is classified into two modes: one is "fault replacement" for replacing faulty disks and one is "preventive replacement" for replacing disks before they become faulty.

The disk drive replacement menu provides guidance information for replacing and mounting disk drives in these modes.

The Machine Administration menu provides the disk drive replacement function with the following menu items:

• The Faulty Hard Disk Drive Replacement (Hot Swap)
  Allows replacement of disk drives without stopping system operation.
• Preventive Maintenance of the Hard Disk Drive (Hot Swap)
  Allows preventive replacement of disk drives based on checking the frequency of errors, such as retries, that have occurred previously.
  Allows hot swapping without stopping system operation.
• Include the Hard Disk Drive after the Cold Maintenance
  Displays guidance information for resetting data and the operation of mounting in SynfinityDISK/GDS after replacement was performed with system operation stopped.

The following sections describe how to perform replacement using these menu items.
