Disk Replacement Wizard, we’re going to do this on a VNX system but the first thing we want to do is take a look and see how a disk error might show up with Unisphere. So, I have Unisphere launched and I’m going to double-click on the system that I found.
So, we’ve already logged into the system, taken care of that, and I can see now that I do have errors here. And I could actually click on one of these errors. And I’ll double-click, and I can see that I have a DPE on Bus 0 Enclosure 0 and that enclosure is faulted. So, I’m going to take a look at that, and to do so we need to go back to the dashboard.
We’ll click on the system itself, and we’ll go to “System.” And we’ll get the Storage Hardware. So, here’s my fault, I can see that by the error message “Bus 0 Enclosure 0.” I’m going to expand the disk, and I’m going to see what the disk is. And here is the fault, here. It’s on Bus Enclosure 0:13, so if I hightlight this I can see where it shows up physically in the chassis.
This happens to be a 2U chassis containing up to 25 drives. So, I can see that. So, I’ve basically validated, yeah, I have a fault. So, I’m going to close this out now. And I’m gonna launch the... ...Unisphere Service Manager utility. And, again, assume that I’ve already logged in, and I’m gonna go to the Hardware part and Hardware Replacement. And I find a “Replace a Faulted Disk” utility. And this we’ll go ahead, and I’ve run through a Wizard, so I’ll double-click on that.
Launch the Wizard, read this, and say “Next.” And once the analysis of the system is complete, I can see that it did identify a replacement candidate. Now, had there not been anything to identify that would have been a red X here, okay? But it did identify something, so I’m going to go ahead and click “Next.” And it says it’s a candidate for disk replacement, and here’s some of the details on that.
So, I’m going to take a look at this, I see the serial number, the system, the type of VNX system, this happens to be a 5100 And, again, I knew this earlier from looking at EMC Unisphere: Bus 0 Enclosure Disk 13. So, I’m going to go ahead, and this procedure assumes the disks you’re installing are new and have no user data on them.
And so “Do you have a valid replacement disk?” I’m gonna go say “yes,” because I do, and then I’m gonna go ahead and click on that. And there’s the disk. I could flash the LEDs, I could do that if I want to locate it, but it basically shows me where it is.
I’m gonna go ahead and do that, that’s the location procedure. And I’ll say “Next” to that. And then I’m gonna come to a whole procedure to do this. And I guess I also can click on this disk replacement instructions. And that will launch... ...several things here too, and tell me how to go through that process.
So, we’ll close out of that. Close down that. Close down that. And I’m gonna go ahead and replace that disk now. Okay, so, I’ve replaced the disk, and disk was replaced and is transitioning. And it gives me some of that information. The next button becomes highlighted, I’m going to go ahead and do that. And then this is going to be some activity performed, and I can fill this in.
I don’t want to really save that, but I could go ahead and fill in this information, and save activity, name - I’ll just put “test.” And, no comments, and go to “Go Hidden.” I’ll do that. Let it go through the summary, and to gather this information. Okay, the summary’s finished. I could view details if I wanted to do that.
In this case I’m going to say “Next” and “Finish”. And that completes the “Replace a Faulted Disk” utility. Now, if I could go back to EMC Unisphere, and I’m gonna go ahead and just check that. You see, it still shows faulted, but I haven’t refreshed the system, so I’m gonna try that.
And, here’s the case, I can see the fault has gone away. The disk that was faulted has come and is now in an equalizing state, so it’s going to go ahead and equalize. It’s going to build back with the hot spare, and and then it will become enabled. So, again, I can highlight that, and that completes the instruction on the “Replace a Faulted Disk” Utility.
