NAME

sym — symmetric access SCSI devices

SYNOPSIS

sym* at scsibus?

DESCRIPTION

The sym driver attaches to SCSI logical units that support symmetric access, i.e. all paths to the device are as good as each other. Each path attached to by sym is presented to mpath(4) which uses it as a backend to the logical unit attached to its own scsibus(4).
