Converting IB-iSER to/from IB-SRP
• You do not have to make any changes to your hardware when you convert from/to iSER to SRP.
• The Data Assurance (DA) feature is not supported for SRP.
• The DA feature is not supported for IB-SRP. If you are currently using this feature via the IB-HIC and you
want to convert those ports from iSER to SRP, you must permanently disable DA on all volumes. Refer to
the online help for SANtricity System Manager to change the settings for a volume to permanently disable
the data assurance setting.
After it has been disabled, DA cannot be re-enabled on the volume.
• Confirm the following:
◦ SANtricity System Manager is accessible via a 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.
Asynchronous and synchronous mirroring are not supported for NVMe over Fabrics. To disable
Asynchronous and Synchronous mirroring, you can use the
disable storageArray
feature=asyncMirror
or disable storageArray feature=syncMirror commands
through the command line interface. Refer to the
Disable storage array feature mirroring
commands under the CLI Command Reference Online Help for more information on how to
disable mirroring.
Change E5700 host protocol
For an E5700 storage array, you can convert baseboard host ports as follows:
• Fibre Channel (FC) to iSCSI
• iSCSI to FC
• iSER to InfiniBand (IB)
• SRP to IB
• NVMe to IB
• NVMe to RoCE
Step 1: 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.
If your current SFPs support data rates of 16 Gbps and 10 Gbps, you can continue to use them after
115
