volumes. Refer to the online help for SANtricity System Manager to change the settings for a
volume to permanently disable the data assurance setting.
Note: After it has been disabled, DA cannot be re-enabled on the volume.
• Confirm the following:
◦ SANtricity System Manager is accessible via web browser.
◦ The storage system is running SANtricity OS (controller firmware) version 08.40.11.00 or
later.
Mirroring operations need same host protocol
Mirroring operations are not affected if the host ports being used for mirroring keep the same
protocol after you apply the feature pack. Even so, before applying the feature pack, you should
confirm that all mirror consistency groups are synchronized. After applying the feature pack, you
should test the communication between the local storage array and the remote storage array. Refer to
the online help for SANtricity System Manager if you have questions on how to do this.
Change host protocol
You can convert the host port protocol of the baseboard host ports from Fibre Channel (FC) to iSCSI
or from iSCSI to FC. If you have an Infiniband (IB) HIC, you can also convert the protocol of the IB
HIC from iSER to InfiniBand, SRP to InfiniBand, NVMe to InfiniBand, or from NVMe to RoCE.
Steps
1. Determine whether you have dual-protocol SFPs on page 118
Use SANtricity System Manager to determine what type of SFP transceivers you have. Because
these SFPs can be used with both FC and iSCSI protocols, they are referred to as
dual-protocol
or
unified
SFPs.
2. Obtain the feature pack on page 120
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.
3. Stop host I/O on page 131
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.
4. Change the feature pack on page 132
You change the feature pack to convert the host protocol of the baseboard host ports, the IB HIC
ports, or both types of ports.
5. Complete host protocol conversion on page 133
After converting the protocol of the host ports, you need to perform additional steps before you
can use the new protocol. The steps you might need to complete depend on the starting and ending
protocols of the baseboard host ports and the HIC ports.
Determine whether you have dual-protocol SFPs
Use SANtricity System Manager to determine what type of SFP transceivers you have. Because these
SFPs can be used with both FC and iSCSI protocols, they are referred to as
dual-protocol
or
unified
SFPs.
About this task
If your current SFPs support data rates of 16 Gbps and 10 Gbps, you can continue to use them after
converting the host port protocol.
