System information

VNX™ System Operations52 of 114 Release 7.0
Restart a Data Mover
The following procedure explains how to perform an orderly, timed or immediate
restart of the network server’s Data Movers or blades. The procedure applies to all
VNX unified and VNX for file systems.
Action
To immediately restart and monitor a Data Mover or blade, use this command syntax:
$ server_cpu <movername> -reboot [cold|warm] -monitor <time>
where:
<movername> = name of the Data Mover or blade
[cold|warm]= defines the degree to which the Data Mover is reset.
•A cold reboot or a hardware reset shuts down the Data Mover completely before restarting,
including a Power on Self Test (POST).
• A warm reboot or a software reset performs a partial shutdown of the Data Mover, and skips
the POST after restarting. A software reset is faster than the hardware reset.
<time> = when the Data Mover or blade is to be restarted, specified as one of the following:
{ now | +<min> | <hour>:<min> }
Note: The default parameter of the -reboot option will be the warm parameter. In case the warm
rebooting fails, the -reboot option will use the cold parameter to reboot the Data Mover. To monitor
an immediate cold restart of server_5, type:
$ server_cpu server_5 -reboot cold -monitor now
Example 2:
To monitor an immediate warm restart of server_5, type:
$ server_cpu server_5 -reboot -monitor now
Output Note
server_5 : reboot in progress .....
