Has anyone seen any issues with a single failing port on a perc 5/i? I am running raid 10 composed of two 500GB seagate disks and two 1TB WD RE4 disks. One of the RE4 disks was marked as failed and it was on port 3. I pulled the RE4 and replaced it with a 2TB WD Green disk as I waited for a replacement RE4. I had no problems for the 7 days or so that I waited for the RE4 replacement and I then pulled and replaced the WD Green with the new RE4. The raid array was rebuilt however 9hrs and 50minutes later the new RE4 on port 3 is again marked as failed.

I'm going to move the RE4 to the unused port 4 and see if I have any better luck however I just wanted to ping this group to see if anyone more experienced than I has seen this before. Thanks for any responses

*Edit* I've moved this post to http://www.overclock.net/t/1391613/perc-5-i-single-port-keeps-being-marked-as-failed as I think this thread is for Tips and Benchmarks and not support. If possible please respond there.

Hey guys. I tried searching through this thread to find an answer to my question, but at 650 pages, it's hard to find anything. Just got a 5i for really cheap and I'm trying to set up my disks. These will be used in ESXi for datastores. I've got the firmware updated on the 5i and everything seems to be working swimmingly. Initially, I wanted a RAID 10 configuration, but after some research, realized you couldn't create multiple virtual disks on the 5i with a RAID 10 setup, so I instead opted for RAID 5. However, I can't get more than one virtual disk created. I create the initial virtual disk, then go back to the main VD page and hit F2 to create another new virtual disk and it's grayed out and not select-able. What am I missing here?

By default creating a vd uses all of the availible disk space. You must manually input the size of first vd and make sure you leave enough for the second vd. Be aware you are SOL if the array becomes corrupted or inoperable because there is no way to easily recover the 2 VDs.

Go to the create array page, and go through everything you usually do, selecting raid5, etc. But go up to the Volume Size section and change the size of the first virtual disk to be, then create it. Then when you go to create a second virtual disk, it will automatically take the remainder as one large one. This is what I have done with my secondary computer, using a PERC 5/i in my x58 intel system (No EFI Bios), I have a 100gb VD #0, and then a 3.4 TB VD #1, OS on VD #0, Storage VD #1.

It works and it's bootable by my non-EFI-motherboard just fine.

Thanks for the response guys. So the issue is, after I initialize the first VD, there's no way to create another, even though there's plenty of space left for another VD. Here's what I'm seeing:

Here's the default size for a VD.



Here's what I set it to, roughly 715GB.



Then I initialize it.



Here's what I got after it's initialized.



When I go to create another, the option is grayed out and un-selectable.



I don't see any options in other menus to create a new VD. Any ideas?

So, I'm a dumbass. Found the submenu for adding a new VD with the leftover space. For anyone who might come to this thread and have a similar question:



Thanks for the help though.

Glad you figured it out. Sorry I wasn't much help further as I couldn't give you a step-by-step without deleting and re-creating my arrays and I don't want to do that. I knew it was possible in there somewhere though.

Doing all of these things is also possible with MegaRAID Storage Manager within windows, and it's a lot easier. The thing is, you may not be possible to do these things from within windows, as your OS resides on those very same disks off of which you're trying to make a RAID in the first place. biggrin.gif

Once I found that submenu it wasn't too difficult, but yeah, MegaRAID is much easier. I would've done that if I was just setting up a Windows server.
