<v ->In this section of the course,</v>



2

00:00:02.130 --> 00:00:03.660

we're going to be talking all about



3

00:00:03.660 --> 00:00:06.030

how to troubleshoot storage device issues



4

00:00:06.030 --> 00:00:08.460

including boot issues, storage issues,



5

00:00:08.460 --> 00:00:11.550

drive performance issues, and issues with RAIDs.



6

00:00:11.550 --> 00:00:13.500

So as we move through this section



7

00:00:13.500 --> 00:00:15.900

we're again going to be focused on domain five,



8

00:00:15.900 --> 00:00:17.670

hardware and network troubleshooting



9

00:00:17.670 --> 00:00:20.220

as we fully cover objective 5.3.



10

00:00:20.220 --> 00:00:23.160

Objective 5.3 states that given a scenario



11

00:00:23.160 --> 00:00:25.860

you must be able to troubleshoot and diagnose problems



12

00:00:25.860 --> 00:00:28.380

with storage devices and RAID arrays.



13

00:00:28.380 --> 00:00:30.060

So as we begin this section,



14

00:00:30.060 --> 00:00:32.460

we're going to first take a look at different boot issues



15

00:00:32.460 --> 00:00:34.980

including the storage device not being found by the bios



16

00:00:34.980 --> 00:00:37.740

or UEFI during the boot process and others.



17

00:00:37.740 --> 00:00:40.800

Then we'll move into some different storage device issues



18

00:00:40.800 --> 00:00:43.620

such as when a device makes a grinding or clicking sound,



19

00:00:43.620 --> 00:00:46.410

it's LED status indicators display a fault to you,



20

00:00:46.410 --> 00:00:49.710

data loss or corruption occurs, and SMART failures,



21

00:00:49.710 --> 00:00:51.840

which stands for the self monitoring analysis



22

00:00:51.840 --> 00:00:53.730

and reporting technology that is built into



23

00:00:53.730 --> 00:00:55.770

most modern storage devices.



24

00:00:55.770 --> 00:00:57.600

Next, we're going to move into our discussion



25

00:00:57.600 --> 00:00:59.220

of drive performance issues



26

00:00:59.220 --> 00:01:01.860

such as low input/output operations per second,



27

00:01:01.860 --> 00:01:03.570

which is known as IOPS.



28

00:01:03.570 --> 00:01:06.090

After that, we'll cover issues with RAID arrays



29

00:01:06.090 --> 00:01:07.890

such as a disc failure in the RAID



30

00:01:07.890 --> 00:01:10.770

or a failure of the entire RAID itself.



31

00:01:10.770 --> 00:01:12.720

As you're going to learn in this section of the course



32

00:01:12.720 --> 00:01:15.000

there are lots of potential storage device issues



33

00:01:15.000 --> 00:01:17.520

that you're going to encounter as a technician in the field.



34

00:01:17.520 --> 00:01:19.710

So let's get started with our coverage



35

00:01:19.710 --> 00:01:21.420

of how to troubleshoot storage devices



36

00:01:21.420 --> 00:01:22.920

in this section of the course.
