To perform maintenance, you might need to shut down a PS Series group. While the group is shut down, volumes are not available.

 

1. Stop all I/O applications connected to the group.

2. Disconnect iSCSI initiators from the group.

3. Shut down each group member. Do not turn off power to the PS Series array until you cleanly shut down the member.

To shut down a member:

a. Click Group.

b. Expand Members and select the member that you want to shut down.

c. Click the Maintenance tab.

d. In the Power panel, click the Shut down button.

e. In the Member shutdown dialog box, enter the grpadmin password and click OK. (Only group administrators can shut down members.)

f. The system displays a warning message that the member is shutting down. Click OK to acknowledge the warning.

4. To turn off array power, turn off all power switches on the array after the shutdown completes.

 

To restart the group, power on all group members.

 

 

Please let me know if you have any questions,

 

Thanks.

 

Hello, 

 The only drawback to using the GUI or SSH CLI, is as the array is shutting down, the network ports are turned off.  Meaning, there is no confirmation when the array is safe to power off.  If you use the GUI/SSH method, make sure you wait 5 minutes before powering off the array. 

 Alternatively, you can connect to the serial port of the active controller, and issue the shutdown command there.  Then you will get a message when the array is fully down.  

Re: Disconnecting.  The best process is shutdown all servers connected to the SAN.  This will insure, that any pending IO in cache is flushed to disk.
