SP(4) BSD Programmer's Manual SP(4)NAMEsp - splice - pseudo-driver providing striping or concatenation
SYNOPSIS
pseudo-device sp count
DESCRIPTION
The sp driver splices together multiple disk partitions into a single sp
disk unit. This unit behaves much like a physical disk. Configuration in-
formation is passed to the sp driver by splice(8) utility. Once config-
ured the sp disk can be accessed through /dev/rsp0a, /dev/rsp1a, etc and
/dev/sp0a, /dev/sp1a, etc without partitioning the newly created splice
disk. The disks created by the sp driver can be carved up into partitions
with disksetup(8).
FILES

SEE ALSOdisksetup(8), newfs(8), splice(8)BUGS
If disksetup(8) is not used to label the disk an error will be reported
when newfs(8) is used to create a file system on the disk. This error is
benign.
When using Disksetup(8) to partition/label a sp disk disksetup(8) will
complain that it can not determine the type of disk. For the time being
tell disksetup(8) that the disk is type SCSI when asked. When given the
choice of how to determine geometry choose "Internal label used by ker-
nel".
