Welcome to the Dell E MC unity XT crew removal and replacement series. In this series of short videos, we're gonna use Unisphere and UEM cli commands to identify faulted custom replaceable units on a Dell E MC unity XT storage system. We'll then look at the ways to prepare the system for service, including service mode and reset and hold modes will demonstrate the removal and replacement of the faulted crew and finally verify the replacement crew is working correctly. The first things you want to do is to log on to the storage system using the Unisphere interface.
This requires that you have initialized the system and provided an IP address in your browser. And once you do that, you're gonna be brought to the page that you see here, you're gonna have to have a user name along with a password. That combination was uh also set up during the initialization process. And once you provide those correct credentials, we'll be able to log in and view the dashboard page.
So from that dashboard page, we're gonna go ahead and uh trace down the error. We see we have a single hardware failure. If you mouse over the icon, you'll see uh some possibilities as to uh what that may be. You can also view the system status as we've done here. You can get your software version the, the date and time and uh and also confirmation that you in fact have a problem.
If you looked at some of the view uh details, it takes you to the system view, summary page and then from that page, you'll see we have a health issue and that health issue calls out the storage process A B embedded IO module. Now, if we go a step further and look at the alerts, we see we have critical alerts.
If you click on that alert, it will give you again confirmation of the uh embedded module being faulted and additional uh information about the uh Acknowledgments and so forth and, and even you can go to the logs and val validate as well that the uh time and date are correct and that the logs themselves log the same failure uh as you saw in the alerts. If we go to the enclosures, view from the system view, we should see the faulted part and you can see that here.
It's the embedded IO module in from the rear uh legend. Uh up in the uh right hand side, any time you see something faulted in the, in the rear, uh it's gonna require you to put the storage processor in a reset and whole condition and you can see the IO personality module, the IO personality module in the embedded module are the same thing. They just called different things uh depending on where you look. So we see a four port uh in in E card here we see slicks. So again, all these, all these crews that I'm pointing out are crews that require you to go to reset. And, and here is the uh envio module show condition shows a major failure, just a confirmation of that. And so at this point, we need to put this in a reset and hole condition.
The only time you wouldn't need to put the uh the sp in a reset and hold when you get a failure from the rear of the chassis is when you have a power supply fail. Now, here's a condition where both SPS are healthy. So there's nothing wrong with the storage process. So that's why we're gonna put it in reset and hold and not service mode. You see by default, the inter service mode is selected, but we're gonna come on down to uh locate the reset and hold operation and we're gonna go ahead and select that reset and hold operation and execute that. Now again, this is a special condition where power is maintained to the SP and it gives you time to uh go ahead and pull out the IO modules or slicks or, or embedded for Ethernet current. It's gonna require a password. And after some time period.
This is gonna be quick here because as an example, you're in reset and home, so your power led will be solid green, your sp fault led will be solid amber. So let's remove the part. If you're in the back of the system, you see those led s we start by removing the management port cable and you then remove any back end cables, you pull the white tab of that uh cable and pull it on out of the sport that your, your back in connectivity. And in this case, we have a couple Ethernet cables going to the four port Ethernet card and you always mark your cables.
That is a habit that you should always do. You push in the orange tab and you're gonna use the lever, you're gonna ease that module on out, grab it by the side and go ahead and uh lay it on the table and you wanna swap the four port meds card. You see here, this is Med zero, that's a four port card. Uh There is another sport here. You see sport one, there's nothing in that board. So we need to take the good for port Meds card and we need to remove it and put it on the new replacement card. So we're gonna do that with the two blue tabs.
You're gonna push those back and free up the uh four port Meds card, pull it on out. You're gonna take the new embedded ion module. And then on that module, you're gonna go ahead and put the four port me card back onto that module. You see the two alignment posts that uh it has to uh align with and then snap it on uh down at this point, you're ready to go back into the chassis. So you just align the board, push it in all the way and then put your liver in all the way and you'll feel a little uh uh click in there and should be snug and secure in the chassis.
Go ahead and cable, your system back up, put your cable back in, put your um management cable back in and now that you've removed and replaced uh the uh embedded IO module, we need to verify its operation. So we can do that by in this case, logging back into the system, looking at the system view. You see there's no errors in the system health. You see it's green up in the uh menu, the alerts that were once uh present have gone away because they were cleared as a result of the uh issue being fixed and even the logs tell you the embedded a module is, is operating normally. So again, the system view should confirm that you see there's no errors. The enclosure shows a good IO module in the legend rear that was amber and to begin with is now uh green as well and finally confirm that with the envio module show command. So at this point, you removed and replaced a embedded IO module on a unity XD storage system.
