Welcome to the Dell EMC 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.
One of 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 here we see the dashboard page and right off the bat, we see we have a hardware error and uh if we mouse over that we'll see the possibilities as to some of the crews that could be at fault here. So I simply clicked on that error and I can see that, uh, I in fact have a hardware fault and it's in a disarray enclosure and that enclosure is on bus one and C enclosure zero. I can get similar information from the view system status. So let's take a look at the alerts page and, uh, we'll see uh when the alert was generated.
So we have a date and time stamp. Uh and we'll see that uh this particular uh error was uh generated. In fact, the uh DAE is at fault here. I mean, it's a critical error. We can then take a look at the log to see if we have the same uh error logged uh at the same time. And you can see here the time frame is the same and that we have that uh disc arraying closure uh faulted and that we have uh an error in that particular controller. So we need to look at the system view to see what type of fault uh we have, see if it points anything else. And in fact, you can see here that on the uh the DAE, we have a link control card, so we need to fix it.
We're gonna do that by first uh open up the cable bracket and then unplug in any S a cables that you may be connected. Now, the LCC is up. You're gonna turn that counterclockwise, pull out that torque limiting screw and pull that straight out. And then you simply go ahead and uh push the other one in, turn the to liens crew uh clockwise until it locks down in place and you'll hear it uh sort of ratcheted through when it's uh complete and then cable in your SASS cables.
So remember the system is still up and running here and then go ahead and uh route all your cables back, put your cables uh bracket back in place. And then let's verify from the system view that the part was fixed. So we go to the enclosures view, we can go to the DAE and uh the D A at this point looks healthy and it looks like it's in a healthy state. That's the normal condition. There's no other faults being shown. So uh in this example, we replaced a link control card in a 80 drive Dae.
