Rebuild: A SCSI disk drive is in a “rebuild” state...
While it is in the process of being rebuilt. During this process, data is
regenerated and written to the disk drive. This state is also referred to as
‘Write-Only’ (WRO).
Segment Size
See “Cache Line Size.”
Session
Refers to the period of time between any two consecutive system shutdowns.
System shutdown may be either a power off/on, or a hardware reset.
Standard Disk Drive
This term refers to a hard disk drive with SCSI, IDE, or other interface, that
is attached to the host system through a standard disk controller.
Standby Replacement of Disks (“Hot Spare”)
The “Standby Replacement” (or “Hot Spare”) is one of the most important
features the controller provides to achieve automatic, non-stop service with a
high degree of fault-tolerance. The rebuild operation will be carried out by
the controller automatically when a SCSI disk drive fails and both of the
following conditions are true:
• A “standby” SCSI disk drive of identical size is found attached to the
same controller;
• All of the system drives that are dependent on the failed disk are
redundant system drives, e.g., RAID 1, RAID 3, RAID 5, RAID 0+1.
