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

119.Pp 120option. 121.Sh BOOT OPTIONS 122The following options are switchable by setting values in 123.Pa /boot/device.hints . 124.Pp 125They are: 126.Bl -tag -width indent 127.It Va hint.isp.0.fwload_disable 128A hint value to disable loading of firmware 129.Xr ispfw 4 . 130.It Va hint.isp.0.prefer_memmap 131A hint value to use PCI memory space instead of I/O space 132access for. 133.It Va hint.isp.0.prefer_iomap 134A hint value to use PCI I/O space instead of Memory space 135access for. 136.It Va hint.isp.0.ignore_nvram 137A hint value to ignore board NVRAM settings for. 138Otherwise use NVRAM settings. 139.It Va hint.isp.0.fullduplex 140A hint value to set full duplex mode. 141.It Va hint.isp.0.topology 142A hint value to select topology of connection. 143Supported values are: 144.Pp 145.Bl -tag -width ".Li lport-only" -compact 146.It Li lport 147Prefer loopback and fallback to point to point. 148.It Li nport 149Prefer point to point and fallback to loopback. 150.It Li lport-only 151Loopback only. 152.It Li nport-only 153Point to point only. 154.El 155.It Va hint.isp.0.portwwn 156This should be the full 64 bit World Wide Port Name you would like 157to use, overriding the value in NVRAM for the card. 158.It Va hint.isp.0.nodewwn 159This should be the full 64 bit World Wide Node Name you would like 160to use, overriding the value in NVRAM for the card. 161.It Va hint.isp.0.iid 162A hint to override or set the Initiator ID or Loop ID. 163For Fibre Channel 164cards in Local Loop topologies it is 165.Ar strongly 166recommended that you set this value to non-zero. 167.It Va hint.isp.0.role 168A hint to define default role for isp instance (0 -- none, 1 -- target, 1692 -- initiator, 3 -- both). 170.It Va hint.isp.0.debug 171A hint value for a driver debug level (see the file 172.Pa /usr/src/sys/dev/isp/ispvar.h 173for the values. 174.It Va hint.isp.0.vports 175A hint to create specified number of additional virtual ports. 176.El 177.Sh SYSCTL OPTIONS 178.Bl -tag -width indent 179.It Va dev.isp.N.loop_down_limit 180This value says how long to wait in seconds after loop has gone down before 181giving up and expiring all of the devices that were visible. 182The default is 300 seconds (5 minutes). 183A separate (nonadjustable) timeout is used when 184booting to not stop booting on lack of FC connectivity. 185.It Va dev.isp.N.gone_device_time 186This value says how long to wait for devices to reappear if they (temporarily) 187disappear due to loop or fabric events. 188While this timeout is running, I/O 189to those devices will simply be held. 190.It Va dev.isp.N.wwnn 191This is the readonly World Wide Node Name value for this port. 192.It Va dev.isp.N.wwpn 193This is the readonly World Wide Port Name value for this port. 194.El 195.Sh SEE ALSO 196.Xr da 4 , 197.Xr intro 4 , 198.Xr ispfw 4 , 199.Xr sa 4 , 200.Xr scsi 4 , 201.Xr gmultipath 8 202.Sh AUTHORS 203The 204.Nm 205driver was written by 206.An Matthew Jacob 207originally for NetBSD at NASA/Ames Research Center. 208Some later improvement was done by 209.An Alexander Motin Aq Mt mav@FreeBSD.org . 210.Sh BUGS 211The driver currently ignores some NVRAM settings. 212.Pp 213Fabric support for 2100 cards has been so problematic, and these cards are so 214old now that it is just not worth your time to try it. 215
