reboot

NAME

na_reboot - stop and then restart the filer

SYNOPSIS

reboot [ -d halt_string ] [ -t minutes fR] reboot [ -s ]
reboot [ -r ]

DESCRIPTION

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.

OPTIONS

-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 Global Services.

This command is only supported by FAS980 filers.

The reboot -r command does not power cycle the appliance shelves.

CLUSTER CONSIDERATIONS

You cannot use the reboot command in partner mode to reboot a failed filer.
