EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
Installing and Configuring the Linux Host with the QLogic Driver
◆ ql2xintrdelaytimer: defines the amount of time for the
firmware to wait before generating an interrupt to the host as
notification of the request completion.
◆ retry_gnnft: defines the number of times to retry GNN_FT in
order to obtain the Node Name and PortID of the device list.
◆ ConfigRequired: If set to 1, then only devices configured and
passed through the
ql2xopts parameter are presented to the OS.
◆ Bind: defines the method for target persistent binding method. If
set to 0, then the Portname is used; if set to 1, the PortID is used.
◆ ql2xsuspendcount: defines the number of 6-second suspend
iterations to perform while a target returns a
NOT_READY status.
◆ ql2xdevflag: defines whether to display the abbreviated
persistent binding statements.
◆ qfull_retry_count: defines the number of retries to perform on
a queue full status from a device.
◆ qfull_retry_delay: defines the number of seconds to delay on
queue full status from a device.
◆ extended_error_logging: defines whether to enable extended
error logging.
◆ ql2xplogiabsentdevice: defines whether to enable a PLOGI to
devices that are not present after a fabric scan. Per QLogic, this is
needed for several broken switches.
◆ ql2xfdmienable: defines whether FDMI registration is enabled.
◆ qlogin_retry_count: defines whether the login retry count will
be modified.
◆ ql2xioctltimeout: defines the IOCTL timeout value in seconds
for pass-through commands.
◆ ql2xprocessnotready: defines whether the driver handles
NOT_READYs.
◆ ql2xuseextopts: defines whether the driver will use the
extended options saved in the module object itself, even if a string
is defined via
ql2xopts.
Failover-specific
parameters
◆ MaxPathsPerDevice: defines the maximum number of paths to a
device.
◆ MaxRetriesPerPath: defines the number of retries to perform on
the current path before failing over to the next path in the list.
