The
options autosupport.noteto
command specifies the recipients of short
email messages sent by
autosupport
. The short email messages are for urgent
events, such as disk failures or filer reboots. The following example shows a short
message:

Short messages are useful if the person who should be notified of urgent events
reads email on a small screen, such as the screen on an alphanumeric pager.

The filer uses two commands and a set of options to control and synchronize the sys-
tem time.
The
date
command sets the time locally.
For example, the following command sets the system date and time to 9:25 a.m.
on May 22, 1999:
date 199905220925
The
rdate
command synchronizes the filers time with the time on another host
with an accuracy of one second.
SNTP (Simple Network Time Protocol) synchronizes the filers time with the time
on a time server with a theoretical maximum accuracy of one nanosecond; actual
accuracy depends on the accuracy of the time server and network delays.

The
rdate
command synchronizes the filers time with a target computers time
using the UDP time service (typically, UDP port 37). This service is available on most
UNIX computers. Check
/etc/services
and
/etc/inetd.conf
on the target computer to
see whether this service is supported.
