PS6210 Hardware Owner's Manual 1 Basic Storage Array Information Shutting Down and Restarting an Array A PS Series array includes redundant, hot-swappable drives, power supplies, and control modules (in a dual control module array). You can remove a redundant component without affecting operation if a functioning component is available. Otherwise, Dell recommends that you cleanly shut down the array and turn off power before removing a component. When an array is shut down, any volumes with data on the array will be set offline until the array is successfully restarted. Being offline affects initiators that are connected to the volumes. Array shutdown procedure 1. Connect to the array in one of the following ways: • Use telnet or SSH to connect to a functioning IP address assigned to a network interface on the array. Do not connect to the group IP address. • Use the null modem cable, shipped with the array, to connect the serial port on the active control module (ACT LED is green) to a console or a computer running a terminal emulator. Make sure the serial line characteristics are as follows: • 9600 baud • One STOP bit • No parity • 8 data bits • No flow control 2. Log in to an account with read-write access, such as the grpadmin account. 3. Enter the shutdown command, as follows: login: grpadmin Password: Welcome to Group Manager Copyright 2001-2013 Dell Inc. group1> shutdown If you are using a serial connection to shut down an array, it is safe to turn off power when the "press any key" message appears. (Pressing any key will restart both control modules.) If you are using a network connection, the session will be disconnected before the array is fully shut down. Confirm that the ACT LED on each control module is off (not lit) before turning off power to the array. After performing array maintenance, you can turn on power to the array. When the array restart completes, the member and volumes will be set online. 6
