Configuring the Driver Parameters
FE0254601-00 A 5-17
ql2xplogiabsentdevice Enables (1) or disables (0) PLOGI (port login) to
devices that are not present after a fabric scan.
Enabling this parameter is required to work around
some Fibre Channel switch defects. The default is 0.
ql2xqfullrampup Number of seconds to wait before increasing the
queue depth for a device after a queue-full condition
has been detected. The default is 120 seconds.
ql2xusedefmaxrdreq PCIe maximum read request size. Adjust the PCIe
maximum read request size (0); use system default
(1). The default 0.
ql2xusedrivernaming Enables (1) or disables (0) the consistent device nam-
ing feature. The default is 0.
qlport_down_retry Maximum number of command retries for a port that
returns PORT-DOWN status. This parameter deter-
mines how long the driver internally queues I/O before
returning the DID_NO_CONNECT status to the SCSI
mid layer. Multiply this parameter by two to determine
the number of seconds that the driver holds the I/O
request. Default is 15.
