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:
Table 12. Recommended configuration file parameters for the QLogic QLA2310F, QLA2340,
and QLA2342 adapters with driver level 4.03
Parameters
hba0-max-frame-length
hba0-max-iocb-allocation
hba0-execution-throttle
hba0-login-timeout
hba0-login-retry-count

Recommended settings
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.
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.
Recommended setting: 0.
Function: Flag for enabling target offline
when target port fails.
1: Default. (Enable).
