Chapter 7. Host port protocol
7.1. Requirements for changing the host port protocol
Before converting the host port protocol in the DE6000, review the
requirements.
The following figure shows the DE6000 with its SFP+ (optical) baseboard host ports *(1)* and the
optional two IB HIC ports *(2)*.
A two-port HIC is also available.
The following figure shows the DE6000 (without two SFP+ (optical) baseboard host ports) with four
HIC ports *(1)*.
For the system without base ports, 2x HICs are required to make the system work
normally. Systems without HICs installed are not allowed to be powered on.
7.1.1. Requirements
•
You must schedule a downtime maintenance window for this procedure.
•
You must stop host I/O operations when you perform the conversion, and you will not be able
to access data on the storage array until you have successfully completed the conversion.
•
You must use out-of-band management. (You cannot use in-band management to complete
this procedure.)
