Ensure that the file module is 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 examining the LEDs of the Ethernet
ports.
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
each time until it is corrected or connected:
1. Verify that each end of the cable is securely connected.
2. Verify that the port on the Ethernet switch or hub is configured correctly.
Contact your network administrator to verify the switch and network
configuration information.
3. Connect the cable to a different port on your Ethernet network.
4. Replace the Ethernet cable.
5. For the 10 GbE Ethernet port, replace the small form-factor pluggable (SFP)
transceiver. Refer to “Removing a PCI adapter from a PCI riser-card assembly”
on page 143 and “Installing a PCI adapter in a PCI riser-card assembly” on
page 145.
Ethernet connectivity between file modules
This topic covers troubleshooting Ethernet connectivity issues between the file
modules. These connections are used for internal management operations between
the file modules. They make use of the Internal IP address range that you
provided during initializing the Storwize V7000 Unified system.
About this task
This procedure is used to troubleshoot Ethernet connectivity between the file
modules. These network paths are used for all internal file system communication.
Between the file module, there are two separate network paths for internal
communication.
