Changing The Mode On 220S And 221S Enclosures
Make sure that you turn off the enclosure before you toggle the bus configuration switch on a 220S or
221S enclosure, the enclosure should be powered off. The bus configuration switch is used to change the
enclosure to split bus, joined bus, or clustered mode. If you change the 220S or 221S enclosure mode
with the enclosure turned on, the enclosure may no longer be displayed by Storage Management and
you may notice erratic behavior. In addition, the bus configuration switch on these enclosures is not
rated for frequent toggling.
Enclosure Management
In addition to the enclosure tasks, the following activities may be required for enclosure management:
• Identifying the service tag of the enclosure — To identify the service tag of the enclosure, select the
enclosure in the tree view and click Information/Configuration. The Information/Configuration
page displays the service tag and other enclosure properties.
• Identifying the Express Service Code of the enclosure — The Express Service Code is a numeric
function of your service tag. You can key in the numeric Express Service Code for automated call-
routing while calling technical support. To identify the Express Service Code of the enclosure, select
the enclosure in the tree view and click the Information/Configuration. The Information/
Configuration displays the Express Service Code and other enclosure properties.
• Preparing a physical disk for removal — To prepare a physical disk for removal is a physical disk
command. See Preparing To Remove.
• Troubleshooting — For more information on Troubleshooting, see Troubleshooting.
• Removing the wrong physical disk — You can avoid removing the wrong physical disk by blinking the
LED display of the disk you intend to remove. See Blinking And Unblinking A Physical Disk.
• If you have already removed the wrong physical disk, see:
– Recovering From Removing The Wrong Physical Disk
– Identifying An Open Connector On The Enclosure
– Checking The Temperature Of The Enclosure
– Verifying The EMM Firmware Version Of The Enclosure
Identifying An Open Connector On The Enclosure
Does my controller support this feature? See Supported Features.
If you have not attached the enclosure to an open connector, you may need to identify a connector on
the controller that can be used for this purpose. To identify an open connector:
1. In the Server Administrator window, under the System tree, expand Storage.
2. Expand the controller object.
The available connectors are displayed. These connectors are numbered starting from zero.
3. Identify a connector that is not attached to storage. If the connector is already attached to storage,
then the connector object can be expanded to display an enclosure or backplane and the attached
physical disks. A connector object that cannot be expanded in the tree view is an open connector
not currently attached to storage. Storage Management displays a number for each connector.
These numbers correspond to the connector numbers on the controller hardware. You can use
these numbers to identify which open connector displayed in the tree view with the open connector
on the controller hardware.
