Active/Passive RAID
A storage device that presents volumes on 
multiple ports of multiple storage 
controllers, and at any point in time a 
volume is only active on the ports of one 
controller and passive on the ports of the 
other controllers. See also 
Active Path

.
Back-side Path
A path between the SANbox SSP and the 
physical storage.
Boot Set
Either of two selectable locations provided 
by SANbox SSP for storing a system 
software image.
CLI
Command Line Interface. SANbox SSP 
provides a CLI through the local 
administrative console (serial port 
console), telnet, or SSH.
Cross-connected
A property of a high-availability 
configuration in which both SANbox SSPs 
connect to both back-end SANs, allowing 
either SANbox SSP to access both 
controllers of a dual-controller RAID.
Default Boot Set
The boot set that becomes the active boot 
set when the system is started, unless the 
user selects a different boot set.
Failback
When a previously failed path is made 
available once again, I/O traffic can 
resume use of that path. In some cases, 
the system begins using the original path 
automatically (auto-failback). In other 
cases, operator intervention is required to 
allow the system to begin using the 
original path (manual-failback).
In an active/passive configuration, the 
term failback commonly refers to traffic 
resuming the use of the primary paths, 
instead of the secondary paths, which 
requires that the primary paths be made 
active.
