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, and you will not be able
to 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. Your Lenovo Sales Representative
can help you determine what hardware you need and help you order the
correct parts.
- If you are attempting
to change the baseboard host ports of your storage array, and it currently
uses dual-protocol (also referred to as unified) SFP transceivers
that you purchased from Lenovo, you do not need to change your SFP
transceivers.
- Dual-protocol SFP transceivers
support both FC (at 4 Gbps, 8 Gbps, 16 Gbps,) and iSCSI (at 10 Gbps),
but they do not support 1 Gbps iSCSI. See Determine whether you have dual-protocol SFPsto determine
what type of SFP transceivers are installed.
