From the BladeCenter Advance Management Module Web interface GUI, select I/O Module
Tasks  Admin/Power/Restart to ensure that the external ports for the I/O modules in bays
3 and 4 are enabled, as shown in Figure 18-12.

18.2.8 SAS Connectivity Module zoning

Zoning is the partitioning of a Fibre Channel fabric into smaller subsets to restrict
interference, add security, and to simplify management. While a SAN makes available several
virtual disks (LUNs), each system connected to the SAN should only be allowed access to a
controlled subset of the LUNs. For a host (initiator) to gain access to the storage subsystem
(target), the initiator HBA WWPN or the switch port to which it is connected must be zoned
with the corresponding target WWPN or the switch port and this zone should be a member of
the active zoneset. Thus, although zoning is a tool to permit or deny access to the devices, it
does not have the intelligence to apply controls beyond the fabric, that is, to present or hide
the LUN to certain hosts.
Several predefined SAS fabric zone configurations are available from the factory and can be
invoked by a simple selection from the Advanced Management Module (AMM). Zoning on the
SAS Connectivity Module can be performed using the AMM I/O module configuration option,
Web GUI, SAS, telnet, and SAS connectivity module (SCM) application.
Select I/O Module Tasks  Configuration in the BladeCenter AMM GUI Web interface
window. For I/O Module 3 or I/O Module 4, select Zone Configuration Management. A
window opens showing the predefined zone configuration options, as shown in Figure 18-13
on page 564.
