+ <title>ATA/SATA subsystem now &man.cam.4;-based</title>
+
+ <para>In &release.current;, &os; ATA/SATA disk subsystem has
+ been replaced with a new &man.cam.4;-based implementation.
+ The &man.cam.4; stands for Common Access Method, which is an
+ implementation of API set originally for SCSI-2 and
+ standardized as "SCSI-2 Common Access Method Transport and
+ SCSI Interface Module". &os; has used &man.cam.4; subsystem
+ to handle SCSI devices since 3.X.</para>
+
+ <para>Although the new &man.cam.4;-based ATA/SATA subsystem
+ provides various functionality which the old &man.ata.4; did
+ not have, it also has some incompatibility:</para>
+
+ <itemizedlist>
+ <listitem>
+ <para>An ATA/SATA disk is now recognized as a device node
+ with a name
+ <devicename>ada<replaceable>0</replaceable></devicename>
+ instead of
+ <devicename>ad<replaceable>0</replaceable></devicename>.
+ Currently, a symbolic link <filename>/dev/ad0</filename>
+ is automatically generated for
+ <filename>/dev/ada0</filename> to keep backward
+ compatibility. This symbolic link generation can be
+ controlled by a
+ <varname>kern.cam.ada.legacy_aliases</varname> (enabled
+ by default). You might want to update
+ <filename>/etc/fstab</filename> and/or consider to use
+ volume label (see &man.glabel.8; for more detail) for
+ specifying each file system to be mounted.</para>

+
+ <listitem>
+ <para>The &man.atacontrol.8; utility cannot be used for

+ utility is a replacement.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &man.ataraid.4; software RAID is supported by
+ &man.graid.8; GEOM class. It generates a device node
+ with a name
+ <filename>/dev/raid/r<replaceable>0</replaceable></filename>
+ if you had
+ <filename>/dev/ar<replaceable>0</replaceable></filename>.
+ Note that this is not enabled by default. To enable it,
+ enter the following line in the &man.loader.8; prompt:</para>
+
+ <screen>set geom_raid_load="YES"
+boot</screen>
+
+ <para>or add the following line to
+ <filename>/boot/loader.conf</filename>:</para>
+
+ <programlisting>geom_raid_load="YES"</programlisting>
+
+ <para>and reboot the system. A symbolic link like
+ <filename>/dev/ar<replaceable>0</replaceable></filename>
+ will be generated for
+ <filename>/dev/raid/r<replaceable>0</replaceable></filename>.
+ Therefore, if your system used
+ <filename>/dev/ar0</filename> as the root partition,
+ mounting local file systems will fail because it is
+ renamed to <filename>/dev/raid/r0</filename>. You need
+ to update <filename>/etc/fstab</filename>
+ manually in that case.</para>
