Welcome to the Dell E MC.
unity XT crew removal and replacement series. In this series of short videos, we're gonna use unsphere 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 from the view here from the Unisphere dashboard, we can see we indeed have a fault. It's a, a single hardware fault. Uh We're gonna go ahead and verify that with the alert. See when uh we generate uh generate an alert.
We can see here we have a, a storage processor uh failure and then we have uh a second failure above that telling us that we have an issue with the uh the enclosure itself, the ARA. So let's again verify that uh in the logs we're looking for the same time uh as always the same uh time as the generated alerts uh in the uh logs. And we uh confirm that indeed the storage processor looks bad.
So from the system view, uh we see we have an error and I can go ahead and click on that error, all the uh crew I should say and I can see the whole top uh S PB uh looks like it has uh faults. OK? So that whole uh the, the whole processor itself. And I can uh that's from the rear view uh in the legend.
So I can see here uh again, the SP uh B is faulted. I can verify that again by looking at the ENV uh show SP and I can see again it has a major fault. So uh just another verification. And so I'll come down to the affected S PB in this example, and I'll put it into service mode by uh entering service mode, you provide your service password.
And then once that uh uh SP is in service mode, the uh sp fault led will be amber uh blue and uh flashing at one second intervals. We're ready to service the system. So we'll go ahead and uh disconnect all the cables. We need to get that sp uh out of the system. And because it's defaulted SP, we're gonna have to transfer all those components.
So you used to be really just uh pull that orange latch uh on the sp, uh pull it all the way out to dislodge that storage processor and then go ahead and uh pull it on out here from the back. So you have a replacement storage processor and you have your old faulted storage processor.
So you're gonna go ahead and uh use those uh blue uh push uh almost like push buttons to open that uh lever and then uh make sure you swap any of the NV modules out in the memory modules. We're gonna identify the uh the uh S sds for us. So I should say the M two device here.
So we're gonna swap that on and we're gonna replace it on to the a new storage processor. And then uh you do gonna do the same thing uh by start uh go ahead and remove your memory modules. Now, you gotta do this one at a time. Of course, you're gonna take one off the old one, you're gonna put it on the new one, make sure it's seated properly.
Press down and you're gonna repeat that procedure for as many dims as you have, uh, in that storage process, it could be 24 of them if you're, uh, fully populated and we continue to, uh, just go ahead and, and, and do that operation. And finally, uh, the last one that we have, so we've done that and, uh, we're gonna swamp all the, uh, cooling modules, uh, cooling modules.
You'll see. Uh, here, I'm, I'm, I'm starting with one here. It's a little blue latch that you just really just pull out and, and take off uh to expose that. And the six of them in the uh uh in the chassis here. So I took one off. You see, I, I have to connect it back on to the motherboard and you're gonna pop it back on there, press it down and, and securely.
Uh see it and you do the next, uh the next uh cooling module, disconnect the uh cable from the motherboard, pull it on straight out and swap uh the second module and you continue to do that until you swapped all six cooling modules. Here goes the last one. So we've done that. We've done the M two devices, we've done the dims, we've done the cooling modules.
Now, we'll swap out the uh battery backup unit. So the battery backup unit, uh has a little dust cover on it and uh, it has a cable uh that connects to the motherboard. You need to take the dust cover off, pull off the cable and there's two little levers that you're gonna press back towards yourself.
Uh And you're gonna pop that uh battery backup unit uh back on and there's two little holes uh in the battery backup unit that have to align to the pegs on the motherboard. Uh Once you align that you, you go ahead and uh insert it, cable it up, put your cover back on and that is the uh completion, at least swapping of the modules on the uh storage processor.
So at this point, uh we should be uh good to go and we're gonna take that. We're gonna um go ahead and uh swap out uh just the remaining uh parts that we have here that weren't internal to the storage processor. So this one's gonna be the uh power supply and you're gonna do power supplies. And in this case, I take the orange lever and I slide out uh the IO modules.
You see, I'm doing this again, one at a time, I'm taking one out, putting in the same slot on the good sp uh one at a time, press in the orange uh lever there. Uh Go ahead and pull the IO Personality uh board out or the embedded IO module. If you want to refer to it as the embedded IO module and you push it in, you make sure it's locked into place.
And at that point, you've replaced uh the uh external, uh, parts of the SP as well. And you're gonna lock that sp into place into the chassis and you're gonna go ahead and, uh, if you took it out of the chassis, just uh, install it in the chassis. Yeah, I, I took it out for demonstration purposes, but it's just showing us that we can install the chassis back in where we had it.
Normally, you don't have to do that. You can do that by uh doing the same thing by just pulling the sp out of the chassis. And then you uh of course, you have your cables marked and then you're gonna uh replace the cables uh the same uh place where you actually uh took them off.
Now, at this point, we're ready to reboot that storage processor out of service mode and we go to the uh unisphere, we find the uh S PB. We're gonna go ahead and select reboot any time. Of course, you go into the service mode, you type in your service password to uh uh allow you to perform the operation and it should come up as a normal uh sp after some uh amount of time and both SPS at this point should show a normal status.
The system view should show a normal status as well and the enclosures uh the enclosures should show uh no faults. And you see this uh in this example, the rear shows as green, the rear uh view shows as green, there are no faults and it looks like everything is good.
All the critical errors uh because we had auto uh enabled for the alerts are gone and the logs are cleared as well. So that is, uh and uh I guess finally verify that uh it works with the UEM cli. So that's how we replace a sp.
