Converting from FC/iSCSI to FC (not applicable to controllers without two base-board
ports on the rear)
•
When converting all host ports to FC, keep in mind that asynchronous mirroring over FC must
occur on the highest-numbered FC port.
•
If you plan to convert the ports being used for mirrored relationships, you must deactivate these
relationships before applying the feature pack.
Possible data loss — If you do not delete the asynchronous mirroring
relationships that occurred over iSCSI before converting the ports to FC, the
controllers might lock down, and you might lose data.
•
If the storage array currently has iSCSI baseboard ports and FC HIC ports, asynchronous
mirroring operations will be unaffected.
Before and after the conversion, mirroring will occur on the highest-numbered FC port, which
will remain the HIC port labeled 2 in the figure. 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.
•
If the storage array currently has FC baseboard ports and iSCSI HIC ports, you must delete any
mirroring relationships that occur over FC before applying the feature pack.
When you apply the feature pack, mirroring support will move from the highest-numbered
baseboard host port (labeled 1 in the figure) to the highest-numbered HIC port (labeled 2 in the
figure).
