You might need to install additional SFP transceivers to add more Fibre Channel
connections to the storage enclosure.
Before you begin
Note: You must have the correct type and speed of small form-factor
pluggable (SFP) transceivers. Using the wrong SFP transceiver might
result in loss of data access.
Be careful when you are replacing the hardware components that are
located in the back of the system. Do not inadvertently disturb or remove any cables that
you are not instructed to remove.
Ensure
that you are aware of the procedures for handling static-sensitive
devices.
About this task
To install additional SFP transceivers, complete the following
steps:
Procedure
- Read the safety precautions in the IBM Systems Safety Notices.
These guidelines help you safely work with the system.
- Shut down all host I/O to the enclosure.
-
If you are installing SFP transceivers in an enclosure that is located at the top of the rack,
you might need to slide the enclosure out of the rack slightly to access the adapters.
- To install a new SFP transceiver,
complete the following steps.
- If used, open the release handle on the SFP transceiver.
-
Push the new SFP transceiver into the
aperture in the adapter until it stops.
- If the SFP transceiver uses
a release handle, close the handle to secure the SFP.
- Gently pull the SFP transceiver.
If it is installed correctly, it does not move from its aperture.
- Repeat step 3 as necessary to install the remaining SFP
transceivers.
- Connect Fibre Channel cables to the new SFP transceivers.
-
To reset the adapters where you installed the new SFP transceivers, enter the svctask
maintenance -action reset -enclosure x -canister
y -adapter z CLI command, where
x, y and z are the numbers of the
enclosure, canister, and adapters.
You can use the
management GUI to determine the enclosure, canister, and adapter numbers. You can also use the
sainfo lsservicenodes CLI command to determine the enclosure and canister
number, then you can use the lsportfc CLI command to determine the adapter
number from the canister number.
- If you had to slide the enclosure out of the rack to install
the SFP transceivers, return the enclosure to its original position
now.
