na_reboot - stop and then restart the filer
reboot [ -d halt_string ] [ -t minutes fR]
reboot [ -s ]
reboot [ -r ]
reboot halts the filer and then restarts it. reboot is
commonly used to allow modified configuration files to
take effect or to run a newly installed version of Data
ONTAP.
NFS clients can maintain use of a file over a halt or
reboot (although experiencing a failure to respond during
that time), but CIFS, FCP, and iSCSI clients cannot do so
safely. Therefore, if the filer is running CIFS, FCP, or
iSCSI you may use the -t option to specify the time before
shutdown. If halt is invoked without -t, it displays the
number of CIFS users, the number of open CIFS files, the
number of mapped LUNs and the number of connected FCP and
iSCSI clients. Then it prompts you for the number of
minutes to delay. cifs terminate automatically notifies
all CIFS clients that a CIFS shut-down is scheduled in
mins minutes, and asks them to close their open files.
CIFS files that are still open at the time the filer
halts will lose writes that had been cached but not written.
FCP and iSCSI will not notify clients, but will
allow administrators to confirm that the mapped LUNs are
not in use. LUNs that are in use at the time the filer
halts will result in client failures.
reboot logs a message in the /etc/messages file (see messages(5))
file to indicate that the filer was rebooted on
purpose.
-d halt_string Dump system core before rebooting. The
halt string should indicate the reason why
the system was rebooted.
- -t minutes
- Reboots after the indicated number of minutes.
- -s
- Initiates a clean system shutdown, followed
by a power cycle reboot. (When the -s flag
is omitted, reboot performs a clean shutdown
but does not power cycle the appliance.)
The reboot -s command is equivalent
to physically turning the power to the head
off and back on after typing "halt".
This command is only supported by FAS980
filers.
The reboot -s command does not power cycle
the appliance shelves.
- -r
- Bypasses the shutdown process and initiates
a power cycle reboot, without first
performing a clean system shutdown. (When
the -r flag is omitted, reboot performs a
clean shutdown but does not power cycle the
appliance.) The reboot -r command is equivalent
to physically turning the power to
the head off and back on, without first
halting the system.
Use this command only when instructed to do
so by Network Appliance Customer Support.
This command is only supported by FAS980
filers.
The reboot -r command does not power cycle
the appliance shelves.
You cannot use the reboot command in partner mode to
reboot a failed filer.
If you reboot the live filer that has taken over the
failed filer, after the reboot, the live filer reinitiates
the takeover process.
