The ‘Hardware’ option located under the ‘Manage’ menu allows you to reboot the active controller of the appliance. Depending on the model type, it may also allow you to view the status of hardware components.
The hardware page for appliance model 1010 is shown below. This page will only allow you to shut down and restart the appliance.
For appliance models 5010 and 7010, this page also allows you to view the status of the various hardware components of the system. The hardware page for appliance models 5010 and 7010 are shown below.
Rebooting and Restarting an Appliance
In situations where you need to reboot the active controller, click the ‘Restart Active Controller’ button. You will be prompted to confirm the action through a browser pop-up. Confirming this action will take you to a progress page as shown below.
For appliance model 1010, performing a restart or a shutdown is a disruptive operation. Typically, an appliance model 1010 will reboot within 5 minutes. When performing a shutdown, you will need to physically press the appliance power button to turn the appliance back on once you have completed your maintenance or other activity that caused the need to shut the appliance down.
For appliance model 5010 and 7010, performing a restart is not disruptive to connected initiators, assuming the standby controller is available. TCP connections between initiators and the active controller will be reset, but will be re-established once the standby controller assumes operation. There may be a temporary (less than 30 second) pause in I/O activity between initiators and the appliance during the course of this operation. If you need to shut down a controller, remove it from the chassis as per the hardware replacement guide. In order to return the controller to service you must insert it into the chassis as per the hardware replacement guide.
Note: Restarting a controller or shutting down an appliance should not be required as part of normal system operation. Shutdown operations are common generally only in cases where failed hardware requires replacement, the unit is being physically moved, or when taking an appliance out of service.
Note: For appliance models 5010 and 7010, connections from iSCSI initiators may not automatically re-establish upon failover if the server using the volume does not have any outstanding IOs waiting for that particular volume. This is expected behavior, and the connection will be re-established when the application using volumes mounted via iSCSI needs to perform IOs against those volumes.
