Removing the Controller from the Array
1.
Label each copper cable or fiber-optic cable that is attached to the controller canister so that you can reconnect
each cable correctly after the controller canister is reinstalled.
2.
Record the information from the seven-segment display on the rear of the base system.
The display flashes a sequence of codes. To find information about the displayed diagnostic codes, refer to the
StorNext Q-Series Storage Install Guide
.
Use either the GUI (first bullet) or the CLI (second bullet) to take the appropriate controller offline.
—
From the
Hardware
pane in the
Array Management
Window, right-click the picture of the controller you
want to take offline, and select
Advanced > Place > Offline
.
—
Run the following command:
SMcli <DNS-network-name-or-IP-address> -c “set controller [(a | b)]
availability=offline;”
If necessary, wait for the Controller Service Action Allowed LED to come on (
on page 4). This indication might
take several minutes for a large configuration.
ATTENTION
Potential degraded performance
– To prevent degraded performance, do not twist, fold, pinch, or step
on the cables. Many cables have a minimum bending radius. For example, do not bend fiber-optic cables
tighter than a 5-cm (2-in.) radius. Check the specifications for your cables, and do not bend any cable
tighter than the minimum specified radius.
