3.2.5 Hot plug task

The hot plug task provides software function for those devices that support hot-plug or hot-swap capability. This includes PCI adapters, SCSI devices, and some RAID devices. Use diag -T identifyRemove to invoke the hot plug task manager.

Depending on the environment and the software packages installed, selecting this task displays the following three subtasks:

￿PCI hot plug manager

￿SCSI hot swap manager

￿RAID hot plug devices

The following section covers the SCSI hot swap manager tasks that are required to handle the hot-swappable six pack of the Models 6C1 and 6E1.

SCSI hot swap manager

This task was known as SCSI Device Identification and Removal or Identify and Remove Resources in some previous releases. This task allows the user to identify, add, remove, and replace a SCSI device in a system unit that uses a SCSI Enclosure Services (SES) device.

Table 3-2shows all available functions of the SCSI hot swap manager task.

SCSI hot swap manager functions

Description

 

 

List the SES devices

All the SCSI hot-swap slots and their contents are listed.

 

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.

 

 

Identify a device attached to an SES

This function is used to help identify the location of a

device

device attached to a SES device. This function lists all the

 

slots that support hot swap that are occupied or empty.

 

When a slot is selected for identification, the visual

 

indicator for the slot is set to the Identify state.

 

 

Attach a device to an SES device

All empty hot-swap slots that are available for the insertion

 

of a new device are listed. 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.

 

 

Replace or remove a device attached to

All populated hot-swap slots that are available for removal

an SES device

or replacement of the devices are listed.
