NAME 33.Nm isp 34.Nd Qlogic based SPI and FibreChannel SCSI Host Adapters 35.Sh SYNOPSIS 36To compile this driver into the kernel, 37place the following lines in your 38kernel configuration file: 39.Bd -ragged -offset indent 40.Cd "device scbus" 41.Cd "device isp" 42.Ed 43.Pp 44Alternatively, to load the driver as a 45module at boot time, place the following line in 46.Xr loader.conf 5 : 47.Bd -literal -offset indent 48isp_load="YES" 49.Ed 50.Sh DESCRIPTION 51This driver provides access to 52.Tn SPI 53or 54.Tn FibreChannel 55SCSI devices. 56.Pp 57SPI supports initiator mode for Ultra SCSI and wide mode transactions for 58.Tn SCSI , 59Ultra2 LVD (1080, 1280), and Ultra3 LVD (10160, 12160). 60.Pp 61Fibre Channel supports initiator and target modes of FCP SCSI profile, 62utilizing Class 3 and Class 2 (2200 and later) connections. 63Support is available for Public and Private loops, Point-to-Point 64and Fabric connections. 65.Sh FIRMWARE 66Firmware loading is supported if the 67.Xr ispfw 4 68module is loaded. 69It is strongly recommended that you use the firmware available from 70.Xr ispfw 4 71as it is the most likely to have been tested with this driver. 72.Sh HARDWARE 73Cards

support for Fibre Channel adapters may be enabled with the 119.Pp 120.Cd options ISP_TARGET_MODE 121.Pp 122option. 123.Sh BOOT OPTIONS 124The following options are switchable by setting values in 125.Pa /boot/device.hints . 126.Pp 127They are: 128.Bl -tag -width indent 129.It Va hint.isp.0.fwload_disable 130A hint value to disable loading of firmware 131.Xr ispfw 4 . 132.It Va hint.isp.0.ignore_nvram 133A hint value to ignore board NVRAM settings for. 134Otherwise use NVRAM settings. 135.It Va hint.isp.0.fullduplex 136A hint value to set full duplex mode. 137.It Va hint.isp.0.topology 138A hint value to select topology of connection. 139Supported values are: 140.Pp 141.Bl -tag -width ".Li lport-only" -compact 142.It Li lport 143Prefer loopback and fallback to point to point. 144.It Li nport 145Prefer point to point and fallback to loopback. 146.It Li lport-only 147Loopback only. 148.It Li nport-only 149Point to point only. 150.El 151.It Va hint.isp.0.portwwn 152This should be the full 64 bit World Wide Port Name you would like 153to use, overriding the value in NVRAM for the card. 154.It Va hint.isp.0.nodewwn 155This should be the full 64 bit World Wide Node Name you would like 156to use, overriding the value in NVRAM for the card. 157.It Va hint.isp.0.iid 158A hint to override or set the Initiator ID or Loop ID. 159For Fibre Channel 160cards in Local Loop topologies it is 161.Ar strongly 162recommended that you set this value to non-zero. 163.It Va hint.isp.0.role 164A hint to define default role for isp instance (0 -- none, 1 -- target, 1652 -- initiator, 3 -- both). 166.It Va hint.isp.0.debug 167A hint value for a driver debug level (see the file 168.Pa /usr/src/sys/dev/isp/ispvar.h 169for the values. 170.It Va hint.isp.0.vports 171A hint to create specified number of additional virtual ports. 172.El 173.Sh SYSCTL OPTIONS 174.Bl -tag -width indent 175.It Va dev.isp.N.loop_down_limit 176This value says how long to wait in seconds after loop has gone down before 177giving up and expiring all of the devices that were visible. 178The default is 300 seconds (5 minutes). 179A separate (nonadjustable) timeout is used when 180booting to not stop booting on lack of FC connectivity. 181.It Va dev.isp.N.gone_device_time 182This value says how long to wait for devices to reappear if they (temporarily) 183disappear due to loop or fabric events. 184While this timeout is running, I/O 185to those devices will simply be held. 186.It Va dev.isp.N.wwnn 187This is the readonly World Wide Node Name value for this port. 188.It Va dev.isp.N.wwpn 189This is the readonly World Wide Port Name value for this port. 190.El 191.Sh SEE ALSO 192.Xr da 4 , 193.Xr intro 4 , 194.Xr ispfw 4 , 195.Xr sa 4 , 196.Xr

205.An Alexander Motin Aq Mt mav@FreeBSD.org . 206.Sh BUGS 207The driver currently ignores some NVRAM settings. 208.Pp 209Fabric support for 2100 cards has been so problematic, and these cards are so 210old now that it is just not worth your time to try it. 211
