# 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).
