The Attach a Device to an SES Device function lists all empty hot-swap slots that are available for the
insertion of a new device. After a slot is selected, the power is removed. If available, the visual indicator
for the selected slot is set to the Remove state. After the device is added, the visual indicator for the
selected slot is set to the Normal state, and power is restored.
The Replace/Remove a Device Attached to an SES Device function lists all populated hot-swap slots
that are available for removal or replacement of the devices. After a slot is selected, the device populating
that slot is Unconfigured; then the power is removed from that slot. If the Unconfigure operation fails, it is
possible that the device is in use by another application. In this case, the customer or system administrator
must be notified to quiesce the device. If the Unconfigure operation is successful, the visual indicator for
the selected slot is set to the Remove state. After the device is removed or replaced, the visual indicator, if
available for the selected slot, is set to the Normal state, and power is restored.
Note: Before you remove the device, be sure that no other host is using it.
The Configure Added/Replaced Devices function runs the configuration manager on the parent adapters
that had child devices added or removed. This function ensures that the devices in the configuration
database are configured correctly.
Standalone Diagnostics has restrictions on using the SCSI Hot-Plug Manager. For example:
v Devices being used as replacement devices must be exactly the same type of device as the device
being replaced.
v New devices may not be added unless a device of the same FRU part number already exists in the
system, because the configuration information for the new device is not known after the Standalone
Diagnostics are booted.
You can run this task directly from the command line. See the following command syntax:
diag -d device-T"identifyRemove"
OR
diag [-c] -d device -T"identifyRemove -a [identify|remove]"
Flag
Description
-a
Specifies the option under the task.
-c
Run the task without displaying menus. Only command line prompts are used. This flag is only
applicable when running an option such as identify or remove.
-d
Indicates the SCSI device.
-T
Specifies the task to run.
SCSI and SCSI RAID Hot-Plug Manager
This task was previously called "SCSI Hot Swap Manager", "SCSI Device Identification and Removal" or
"Identify and Remove Resources" in previous releases. This task allows the user to identify, add, remove,
and replace a SCSI device in a system unit that uses a SCSI Hot Swap Enclosure device. This task also
performs these functions on a SCSI RAID device attached to a PCI-X RAID Controller. The following
functions are available:
v List the SCSI Hot Swap Enclosure Devices
v Identify a Device Attached to a SCSI Hot Swap Enclosure Device
v Attach a Device to an SCSI Hot Swap Enclosure Device
v Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device
v Configure Added/Replaced Devices
The List the SCSI Hot Swap Enclosure Devicesunction lists all the SCSI hot-swap slots and their
contents. Status information about each slot is also available. The status information available includes the
slot number, device name, whether the slot is populated and configured, and location.
