Table 38. How to connect Fibre Channel cables from file modules to the control enclosure.
File module Control enclosure
▌A▐ File module 1 ▌C▐ Control enclosure
▌1▐ Fibre Channel slot 2, port 1 ▌5▐ Node canister 1 Fibre Channel port 1
▌2▐ Fibre Channel slot 2, port 2 ▌7▐ Node canister 2 Fibre Channel port 1
▌B▐ File module 2 ▌C▐ Control enclosure
▌3▐ Fibre Channel slot 2, port 1 ▌6▐ Node canister 1 Fibre Channel port 2
▌4▐ Fibre Channel slot 2, port 2 ▌8▐ Node canister 2 Fibre Channel port 2
The Storwize V7000 control enclosure contains an upper and lower (inverted)
canister.
In isolating problems, be sure to review the labels on the rear of the systems for
exact port plugging.
Software detected problems via event codes:
If a software event code directed you to this procedure, use the Monitoring >
System page in the management GUI to identify the effected file module or refer
to the following procedure to determine the logical to physical mapping of the
event, then proceed to the physical hardware isolation procedures.
The isolation of Fibre Channel connections based on a single error event is not
simple. As Figure 41 on page 73 shows, there are two file modules attached to the
control enclosure; however, the logical host name of these systems does not map
directly to the connections. The logical host name of the file module depends on
which file module is used for initial USB flash drive installation. For example, in
Figure 41 on page 73, file module ▌B▐ can have a host name of mgmt001st001 if the
installation was initiated on that node or it might have a host name of
mgmt002st001 if the installation was initiated on the second file module. Each error
event is reported against the logical host name where the problem occurred.
For isolation of Fibre Channel connections, it is important with a single file module
that both Fibre Channel connections go to the same port number on both Storwize
V7000 node canisters. Port 1 always goes to node canister 1, and port 2 goes to
node canister 2.
Use the following table for correlating the error code with the physical connections,
then follow the procedures after the table for enabling the LED indicator on the
front of the file module.
