TSM Software

For more information about OSM software, see OSM online help and the OSM User's Guide.

Guide.

OSM Service Connection or TSM

Service Application Action

Description

Test Verify This action runs a vendor-supplied power-on

self-test (POST) that checks the internal circuitry of

the disk drive. This test can affect the performance

of the disk. Stop all processes from accessing the

affected disk drive before performing this test.

Validate Checksum This action scans the user data area of a disk for

sector checksum errors. If the action fails, the

Action Details dialog box reports that a sector

checksum error has been found and suggests that

you spare the sector only if you believe there is a

drive media problem.

Responsive Test This action verifies that the disk is installed and

responding.

Alarms An alarm reports faults or abnormal conditions on a

server, such as a failed disk drive. You can view

alarms that currently exist for operating system

resurces using the OSM Service Connection or the

TSM Service Application.

Events If your disk-related error is not identified using

DSAP or through OSM or TSM actions or alarms,

look for disk-related events. Use the OSM or TSM

Event Viewer to retrieve and view events related to

the error from EMS-formatted log files ($0, $ZLOG,

or an alternate collector).

Viewer online help.
