hub A communications infrastructure device to which nodes on a multi-point bus or
loop are physically connected. It is used to improve the manageability of physical
cables.
I/O module
Input/Output module. The enclosure element that is the Fibre Channel drive
enclosure interface to the host or controller. I/O modules are bus speed specific,
either 1 Gb or 2 Gb.
IDX
A 2-digit decimal number portion of the HSV controller termination code display
that defines one of 32 locations in the Termination Code array that contains
information about a specific event.

in-band The method of communication between the EMU and controller that utilizes the
communication Fibre Channel drive enclosure bus.
INFORMATION A drive enclosure EMU condition report that may require action. This condition
condition is for information only and does not indicate the failure of an element. All
condition reports have precedence over an INFORMATION condition.
initialization A process that prepares a storage system for use. Specifically, the system binds
controllers together as an operational pair and establishes preliminary data
structures on the disk array. Initialization also sets up the first disk group, called
the default disk group.
