Integrating Hardware
This section describes the hardware tasks required to attach devices to the Open SCSI
for Fibre Channel controller and lists specifications for necessary hardware.
The IOP supports the attachment of unmodified Fibre Channel drives from their original
manufacturer to NonStop NS-series servers. The IOP contains the vendor ID, product
ID, and device characteristics of Fibre Channel drives. Fibre Channel drives require a
device login before you can attempt any I/O operation on them. The IOP sends a login
I/O to the controller to perform a device port login to obtain the device information for
Fibre Channel drives. This operation can take at least 12 seconds to complete.
Adding a Device
To add an Open SCSI Fibre Channel device to a NonStop system, you do not specify a
SCSI ID. Instead, you specify the PRIMARYPORTNAME (WWN) and LUN of the
device. Use the SCF ADD SCSI command.
Assigning Worldwide Names
The worldwide name (WWN) is specified through the Subsystem Control Facility (SCF)
interface, which allows you to configure and manage storage devices online. For
details on using the SCF, see the SCF Reference Manual for the Storage Subsystem
