Preface
The following ATTENTION statements appear in this publication
and describe practices that must be observed while installing or
servicing a product. An ATTENTION statement provides essential
information or instructions for which disregard or noncompliance
may result in equipment damage or loss of data.
ATTENTION ! Activating a preferred path can result in receipt of out-of-
order frames if the preferred path differs from the current path, if input and
output (I/O) is active from the source port, and if congestion is present on the
current path.
ATTENTION ! When configuring a PDCM array that prohibits E_Port
connectivity, mistakes can render ISLs unusable and cause complex routing
problems. These problems can be difficult to fault isolate and sometimes
manifest incorrectly as end-device issues.
ATTENTION ! If zoning is implemented by WWN, removal and replacement
of a device HBA or Fibre Channel interface (thereby changing the device
WWN) disrupts zone operation and may incorrectly exclude a device from
a zone.
ATTENTION ! If zoning is implemented by port number, a change to the
director or switch fiber-optic cable configuration disrupts zone operation and
may incorrectly include or exclude a device from a zone.
