mscsi(F) 06 January 1993 mscsi(F) Name mscsi - SCSI peripheral device and host adapter configuration file Description /etc/conf/cf.d/mscsi is a description of each SCSI peripheral device con- nected to a host adapter. SCSI peripheral devices and host adapters are configured statically in the kernel by the Link Kit using this file. Each line in mscsi represents one SCSI device connected to a host adapter, and contains five fields separated by spaces or tabs. Each field described below must be supplied with a value. ha The prefix name of the host adapter driver for the adapter con- nected to the peripheral device. Each adapter expects to find an array named xxcfg in the kernel where xx is the handler pre- fix for the driver. A host adapter driver that is present in the kernel, but is not statically configured through the mscsi file, is referred to as non-configured. The keyword auto can be used in this field to reserve space for at most one non-config- ured host adapter driver. There may be several ``auto'' lines, but each line must correspond to a different permitted peri- pheral driver. attach The name of the peripheral driver that controls the device. Possible values are: Sdsk Direct-access disk device Srom CD-ROM device Stp Sequential-access tape device number The host adapter number distinguishes different host adapters controlled by a single adapter driver. The first adapter will have this field already set to 0 (zero) but for a non-config- ured host adapter, the field should be set to 0 (zero) and ha field set to auto. ID The SCSI identification number of the peripheral device. lun The SCSI logical unit number of the peripheral device. The first adapter will have this field already set to 0 (zero) but for a non-configured host adapter, the field should be set to 0 (zero) and ha field set to auto.
