Effect of changes in a production
fabric
Zone changes in a production fabric can result in a disruption of
I/O under conditions where an RSCN is issued as a result of a zone
change and the HBA is unable to process the RSCN fast enough.
Though RSCNs are a normal part of a functioning SAN, the pause
in I/O might not be acceptable. For these reasons, it is
recommended to perform zone changes only when the resulting
behavior is predictable and acceptable. Changing HBA drivers can
rectify the situation.
Confirming operation After changing or enabling a zone configuration, the user should
confirm that the nodes and storage are able to identify and access
one another. Depending on the platform, the user might need to
reboot one or more nodes in the fabric with the new changes.
