IBM RS/6000 Concurrent Mode, Key from a defined terminal produces Confirm, Share-test, Varyoff

Note: Pressing		the	F3	key (from a defined terminal) produces		a	"Confirm		Exi
popup menu which offers two options: continuing with					the	shutdown		by
pressing		F3;	or	returning to diagnostics by pressing	Enter.
For undefined terminals, pressing 99 produces a full					screen		menu	which
offers	two		options: continuing with the shutdown by		pressing		99	and	t
Enter;	or	returning to diagnostics by pressing Enter.

Concurrent Mode

Concurrent mode provides a way to run Online Diagnostics on some of the sy resources while the system is running normal system activity.

Because the system is running in normal operation, some of the resources tested in concurrent mode. The following resources cannot be tested in con mode:

Ÿ SCSI adapters connected to paging devices

Ÿ The disk drive used for paging

ŸSome display adapters

ŸMemory

ŸProcessor

There are	three		levels of testing in concurrent mode:
Ÿ The share-test		level	tests		a	resource	while	the resource is		being	shared
grams running		in	the	normal		operation.	This	testing is	mostly	limited	to no
commands	that test			for	the presence of			a device	or adapter.

ŸThe sub-test level tests a portion of a resource while the remaining part

resource is being used in	normal operation. For example, this test could
port of a multiport device	while the other ports are being used in
tion.

ŸThe full-test level requires the device not be assigned to or used by a

operation. This level of testing					on a	disk drive may require the use
varyoff		command. The	diagnostics		display	menus to allow you to vary off
needed		resource.
Error	log	analysis is	done in	concurrent		mode when you select the Problem
nation	option on the		DIAGNOSTIC	MODE	SELECTION	menu.

To run the Online Diagnostics in concurrent mode you must be logged onto t operating system and have proper authority to issue the commands (if nee help).
