File Module To Control Enclosure - IBM Storwize V7000 Unified Series Problem Determination Manual

If you are looking at a problem regarding built-in Ethernet port 3, built-in Ethernet
port 4, or any network connections to PCI slot 4, refer to "Host to file modules
connectivity" on page 24.
Isolation procedures:
Ensure that both the file module are powered up before you begin this procedure.
The network connection being diagnosed must be connected to an active port on
your Ethernet network:
v Determine the state of the Ethernet LEDs by examining the Ethernet port LEDs.
v The activity LED flashes when there is activity on the connection. The link state
LED must be permanently on. If it is off, the link is not connected.
If your link is not connected perform the following actions to check the port status
until it is corrected or connected:
1. Verify that each end of the cable is securely connected.
2. Replace the Ethernet cable.
3. Replace the failed Ethernet port on the server by replacing the system planer.
Refer to "Removing the system board" on page 149 and "Installing the system
board" on page 151.

File module to control enclosure

This topic covers troubleshooting network connectivity issues between the file
modules and the attached control enclosure. These connections are used for block
storage system configuration as well as command-line interface (CLI) operations to
the control enclosure.
This procedure is used to troubleshoot Ethernet network connectivity between the
file modules and the control enclosure. These network paths are used for all
management operations between the file module and the control enclosure.
There are no direct physical network connections between the file module
hardware and the control enclosure. All network connections are done through the
customer's network infrastructure. When configuring your customer-supplied
network switches, be sure that there is an available communication path between
the file module network connections and the control enclosure network
connections.
If you want redundancy, connectivity of the control enclosure to the file modules
requires that all four of the physical network paths that are available on the control
enclosure are connected to the customer network. If you do not want redundancy,
connecting port 2 of the control enclosure to the customer network is optional.
Verify the control enclosure system IP settings:
Verify that the IP configuration is properly set on the Storwize V7000 Unified
storage control enclosure by doing the following:
v Use the USB key to obtain the information for the control enclosure node
canister status. Refer to "Problem: Storage system management IP address
unknown" on page 190. The status, speed, and MAC address are returned for
