FibrChanl-01 (fcd) B.11.11.16 Fibre Channel Mass Storage Driver Release Notes, Edition 3.0 (September 2008)

Table 11 HP-UX 11i v1 December 2005 Fixes (continued)
Concurrent BDRs issued to the same device when both BDRs failed, the application that
issued the commands hangs instead of timing out. Single BDRs repeatedly timed out due
to a timer reset issue. Both of these have been corrected by changing the way that a failed
BDR request is retried.

A turbulent link may result in I/O hang in the fibre channel controller firmware which
triggers an I/O timeout fatal error processing in the fibre channel driver.The fibre channel
controller firmware was modified to notify the driver once when multiple unsuccessful LIP
(Loop Initialization Primitive) sequences occur. This would help the driver to flow control
the I/Os and also to abort any I/Os that are already posted to the controller firmware, if the
LIP storm persists for over 10 seconds.
