Chapter 8. Host port protocol conversion
8.1. Requirements for DE6400 or DE6600 host protocol
conversion
Before converting the host protocol for a DE6400 or DE6600 array, review the
following requirements.
• 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 Lenovo 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.
8.2. Change host protocol for a DE6400 or DE6600
Follow this procedure to change the host port protocol in a DE6400 or DE6600
array. This procedure applies only to host interface cards (HICs) using either
Infiniband (IB) or Fibre Channel (FC).
8.2.1. Step 1: Obtain the feature pack key
To obtain the feature pack key, you need the serial number from the controller shelf, a feature code,
and the Feature Enable Identifier for the storage array.
Steps
1. Locate the serial number.
a. From ThinkSystem System Manager, select Support › Support Center.
b. With the Support Resources tab selected, scroll to the View top storage array properties
section.
c. Locate the Chassis Serial Number, and copy this value to a text file.
