To partition, format, and mount under FreeBSD
1 Boot the system and log in as root.
2 Open a terminal window.
3 Partition the unit:
fdisk -BI /dev/da0;
disklabel /dev/da0 | disklabel -B -R -r da0
4 Create or make the file system:
newfs /dev/da0c
5 Mount the volume:
mount /dev/da0c /mnt
You can also use sysinstall to format and partition the unit.
You can designate an available drive as a hot spare. If a redundant unit
degrades and a hot spare the size of the degraded disk (or larger) is available,
the hot spare will automatically replace the failed drive in the unit without
user intervention.
Note:
When a hot spare replaces a failed drive, an event notification is generated
and appears in the list of alarms in 3DM. You can also have 3DM send you an email
about this. See "Managing E-mail Event Notification" on page 82.
It is a good idea to create a hot spare after you create a redundant unit.
