Host port protocol conversion
You can convert the protocol of a host to a different protocol so that compatibility and you can
convert the protocol of your host connections to a different protocol to match your infrastructure
needs.
Overview and requirements
Learn about the requirements you need to know about before converting the host protocol.
Requirements for changing the host protocol
Learn about the requirements you need to keep in mind when changing the host port protocol.
• You have scheduled a downtime maintenance window for this procedure.
• You must stop host I/O operations when you perform the conversion. You cannot access data
on the storage array until you have successfully completed the conversion.
• You are using out-of-band management. (You cannot use in-band management to complete this
procedure.)
• You have obtained the necessary hardware for the conversion, which may include a new set of
HICs and/or SFPs. Your NetApp Sales Representative can help you determine what hardware
you need and help you order the correct parts.
• The dual-protocol SFP transceivers support 16Gb and 8Gb FC, as well as 10Gb iSCSI.
Therefore, you may not need to change SFPs if you have the dual-protocol and are simply
switching between FC and iSCSI or vice versa.
• Some host port protocol conversions may require a host interface card addition, or upgrade.
Follow the instructions in the
Host interface card
section for this requirement.
This section describes how to change the host port protocol for the following controller shelves:
• EF300 controller shelf
• EF600 controller shelf
Change host protocol
If you have an Infiniband (IB) HIC, or a Fibre Channel (FC) HIC you can change the host port
protocol using the process in the following section.
Steps
1.
Obtain the feature pack key
on page 74
To obtain the feature pack, you need the serial number from the controller shelf, a Feature
Activation Code, and the Feature Enable Identifier for the storage array.
2.
Stop host I/O
on page 78
You must stop all I/O operations from the host before converting the protocol of the host ports.
You cannot access data on the storage array until you successfully complete the conversion.
3.
