Table 11. Recommended configuration file parameters for a AMCC FCX-6562, AMCC
FCX2-6562, AMCC FCE-6460, or a AMCC FCE-1473 adapter (continued)
Parameters Recommended settings
PlogiControlSeconds 30: Default.
Defines the number of seconds that the
driver waits for a successful port login
(PLOGI) attempt. The maximum number of
attempts is defined by the PlogiRetryCount
parameter. Some devices might take longer
to respond to PLOGIs; if this is the case,
increase the value of this parameter.
FcEmldEngTcbCount 1789: Default.
Total number of concurrent exchanges (also
called transfer control blocks) that the
adapter allows. To optimize performance, set
this parameter to match the memory capacity
of the hardware.
TargetOfflineEnable Recommended setting: 0.
Function: Flag for enabling target offline
when target port fails.
1: Default. (Enable).

You can use these recommended configuration settings for your QLogic adapters
on a Sun host system.
Table 12 provides configuration settings that are recommended for the QLogic
QLA2310F, QLA2340, and QLA2342 adapters. These settings are for a storage unit
that is attached directly to or through a fabric switch. For the most current
information about fibre-channel adapter parameter settings, see:
