42 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
Create a host/IBM Storwize V5000 Gen2 zone for each server that volumes are mapped to
and from the clustered system, as shown in the following examples in Figure 2-4 on page 41:
Zone Host A port 1 (HBA 1) with all node canister ports 1
Zone Host A port 2 (HBA 2) with all node canister ports 2
Zone Host B port 1 (HBA 1) with all node canister ports 3
Zone Host B port 2 (HBA 2) with all node canister ports 4
Similar zones must be created for all other hosts with volumes on the IBM Storwize V5000
Gen2 I/O groups.
Verify the interoperability with which the IBM Storwize V5000 Gen2 connects to SAN switches
or directors by following the requirements that are provided at this website:
https://ibm.biz/BdrDWV
Switches or directors are at the firmware levels that are supported by the IBM Storwize V5000
Gen2.
2.3 FC direct-attach planning
The IBM Storwize V5000 Gen2 can be used with a direct-attach Fibre Channel host
configuration. The advised configuration for direct attachment is at least one Fibre Channel
cable from the host that is connected to each node of the IBM Storwize V5000 Gen2 to
provide redundancy if one of the nodes goes offline, as shown in Figure 2-5 on page 43.
Important: The IBM Storwize V5000 Gen2 port login maximum that is listed in the
restriction document must not be exceeded. The document is available at this website:

Connectivity issues: If any connectivity issues occur between the IBM Storwize V5000
Gen2 ports and the Brocade SAN switches or directors at 8 Gbps, see this website for the
correct setting of the fillword port config parameter in the Brocade operating system:
