Controller Failover Mode (for redundant controller only), each port’s ID,
name, WWN, Hard loop ID, connection mode (private loop, public loop,
or point-to-point), and data rate. For SAS ports including each port’s ID,

Caution
The boot-up delay time must be longer than the disk access delay
time plus 5 seconds.

In redundant-controller systems, the four FC ports are given
identifiers fcpa1, fcpa2, fcpb1, and fcpb2 to identify the
corresponding port positions located on each controller.
Controller
Failover Mode (For FC port with redundant controller only)
Multipath IO: This mode allows the host computer
to access the RAID system over multiple paths. To
use this mode, Pathguard needs to be installed.
See 5.1 Multi-Path IO Solutions for more
information.
Multiple-ID: This function requires the use of fiber
switch. When you select this function, only simple
method is available for storage provisioning. See
5.2 Multiple ID solutions for more information.
Name Type a name associated with each FC/SAS/SCSI
port. The maximum name length is 15 bytes. For
SAS ports please jump to step 4 after setting name.
Hard Loop ID Select a fixed loop ID for each FC port from the
drop-down menu. To disable hard loop ID, select
Auto. The loop ID is automatically determined
during loop initialization procedure.
