When a failure occurs on a single fibre-channel link, the SFP connector might
need to be replaced.
The SFP connector is
designed to be hot-plugged, so that you do not need to power off the SAN Volume Controller node.
CAUTION:
Some laser products contain an embedded Class
3A or Class 3B laser diode. Note the following information: laser
radiation when open. Do not stare into the beam, do not view directly
with optical instruments, and avoid direct exposure to the beam. (C030)
Perform the following steps to remove and then replace the SFP connector:
- Carefully determine the failing physical port connection.
See Fibre-channel port numbers and worldwide port names for
illustrations of the fibre-channel port locations.
Important: SAN Volume Controller nodes
are now supported with both long-wave SFPs and short-wave SFPs. A
long-wave SFP has some blue components that are visible even when
the SFP is plugged in. You must replace an SFP with the same type
of SFP that you are replacing. If the SFP to replace is a long wave
SFP, for example, you must provide a suitable replacement. Removing
the wrong SFP connector could
result in loss of data access.
- Remove the fibre-channel cable by pressing
the release tab and pulling the cable out. Be careful
to exert pressure only on the connector and do not pull on the fibre-channel
cables.
- Remove the SFP. There are a number of different handling
or locking mechanisms that are used on the SFP connectors. Table 1 describes
the usual type of mechanisms that are found on a SAN Volume Controller model.
It is possible, however, that the installed SFP connectors have
a different mechanism than is indicated.
Table 1. Instructions for removing the SFP connector| SAN Volume Controller model |
Removal instructions |
| SAN Volume Controller models 2145-CF8,
2145-8A4, 2145-8G4, and 2145-8F4 |
Locate the release handle that is incorporated
into the SFP connector,
unclip the handle, and then use the handle to pull out the SFP connector. |
| SAN Volume Controller 2145-8F2 and SAN
Volume Controller 2145-4F2 |
Locate the small black locking tag on the bottom
of the SFP connector,
push it back, and then pull out the SFP connector. |
Note: Other SFP connectors might
have a plastic tag. If so, pull the tag to remove the SFP connector.

Important: The customer might be
using a non-standard SFP connector.
If so, the customer should alert you as to the SFP connector to
use, and provide the SFP connector to
you. Always check that the SFP connector that
you replace matches the SFP connector that
you remove.
- Push the new SFP connector into
the aperture and ensure it is securely pushed home. The SFP usually
locks into place without having to swing the release handle until
it locks flush with the SFP connector. Figure 1 illustrates
an SFP connector and
its release handle.

- Reconnect the fibre-channel cable.
- Confirm that the error is now fixed. Check the fibre-channel
port status using the front-panel display.
If possible, check the status given by the customer's SAN monitoring
tools. Either mark the error as fixed or restart the node depending
on the failure indication that you originally noted.
