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.

Table 3-2 SCSI hot swap manager functions

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.
