Target persistent binding method. 0 = bind by port name (default); 1
= bind by port ID.
Option to enable extended error logging. 0 = no logging (default); 1 =
log errors.
Maximum number of simultaneous commands allowed for an adapter.
Number of retries to perform on Queue Full status from device.
Default is 16.
Number of seconds to delay on Queue Full status from device.
Default is 2.
Option to enable allocation of memory for a firmware dump during
adapter initialization. Memory allocation requirements vary by ISP
type. 0 = memory not allocated (default).
Minimum command timeout value. Default is 30.
Set to 1 to display abbreviated persistent binding statements.
Enables FDMI registrations. 0 = no FDMI (default); 1 = perform
FDMI.
Option to specify to load ISP24xx firmware from Flash or embedded
in driver. 1 = load firmware from Flash. 0 = load firmware embed-
ded with driver (default).
Waiting time for firmware before it generates an interrupt to the host
to notify completion of request.
Ioctl timeout value in seconds for pass-through commands. Default is
66.
Login timeout value in seconds. Default is 20.
Maximum queue depth to report for target devices. Default is 32.
Maximum sectors per I/O request. Default is 512.
Maximum scatter or gather entries per I/O request. Default is 32.
Option to enable operation mode for ISP23xx or ISP24xx. For
ISP23xx, set to 0x5 to enable zero input output (ZIO) mode. For
ISP24xx, set to 0x5/0x6 to enable ZIO mode.
Option to enable PLOGI (port login) to devices that are not present
after a fabric scan. This workaround is required for some FC switch
defects. 0 = no PLOGI (default); 1 = perform PLOGI.
