na_reboot - Stops and then restarts the node.
reboot [ -t minutes ]
reboot [ -s ]
reboot [ -r ]
reboot [ -d dump_string ]
reboot [ -f ]
reboot halts the node 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 the node will fail to respond during that
time. CIFS, FCP, and iSCSI clients cannot safely maintain
use of a file over a halt or reboot. If the node is
running CIFS, FCP or iSCSI, you may use the -t option to
specify the time before shutdown. If reboot 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 node reboots 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 node reboots will result in client
failures.
reboot logs a message in the /etc/messages file (see
messages(5)) file to indicate that the node was rebooted
on purpose.
-t minutes
Reboots after the indicated number of minutes.
Applies only if the node is running CIFS, FCP,
or iSCSI.
- -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".
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 technical support.
The reboot -r command does not power cycle the
appliance shelves.
- -d dump_string
-
Dumps system core and reboots the node. This
results in a dirty shutdown; cached data will
not be flushed to disk. The dump_string should
indicate the reason for the core dump. Because
it results in a dirty shutdown, the -d option
generally should not be used for normal
maintenance (see NOTES in na_halt(1)).
- -f
- Applies only to nodes in a High Availability
(HA) configuration. If you enter the reboot -f
command on a node, its partner does not take
over.
You cannot use the reboot command in partner mode to
reboot a failed node.
If you reboot the live node that has taken over the failed
node, after the reboot, the live node reinitiates the
takeover process.
