Dell 2850 not recongizing new HD

Our other server detected the new HD during the hot swap, but this 2850 has not. Lights on the front of the bay, show the HD is getting power. I know we have 3 drives, but dont know if the RAID is , nor if it is hardware or software. Any ideas how to get this working?

Are you trying to replace a failed drive, or simply add an additional single drive to the server?  Do you have OMSA installed?

just adding a new drive, what is the OMSA

We had a similar issue with a Dell PowerEdge 4400.  The system was a RAID-5 setup and was running on 2 hard drives even though we had 2 hot spares installed.  We found the way to get it to go was by upgrading the firmware for the PERC.  Once the new firmware was installed the system picked up the third hard drive to replace the failed drive and repaired the degraded raid.

Are you running the latest firmware on your RAID controller?

im going to guess no, it's been awhile. so i should start with upgrading the firmware

at one time we had that, not any more, i should download that, free?

PowerEdgeTechIT ConsultantCommented:
If you are just trying to add a drive to the server, you MUST configure it in the RAID controller (in the management software - OMSA, or in CTRL-M during POST) before the OS will be able to see it.

ok downloading OMSA now

If this disk was used in a system with a firmware revision > then the one running in your controller, then depending on specifics of the model number, the controller will reject the drive.  The sure-fire way to resolve the issue is to attach the disk to a NON-RAID controller and zero out the drive (with linux you can use dd if=/dev/zero of=/dev/xxxx  bs=1024k)  

This assumes problem is that the controller itself rejects the disk.  If the O/S can't see it, as PowerEdgeTech asked, then that is what is supposed to happen.  The controller must be told what to do with the disk, like is it a hot spare, or something that needs to be presented to the host o/s.

Once downloaded, run to extract the files, then run C:\Openmanage\windows\setup.exe, choose Custom and make sure that Storage Management is installed.  Then go to Storage, PERC, Connector/Enclosure, Physical Disks ... if your disk is showing Ready, then go to Storage, PERC, Information/Configuration (link at top of page), then Create/New from dropdown menu of Available Tasks for the controller.

new HD right out of the box , into the 4th bay in the 2850, once open manager is installed pretty easy to make it detect hd?
0
 
PowerEdgeTechIT ConsultantCommented:
Yes, if the server detects it, OMSA will see it.  Look under Physical Disks to see it.

on the "ready" one, do i assign to hot spare?

PowerEdgeTechIT ConsultantCommented:
Your drives were originally in a 3-disk RAID 5?  If so, you should fix your failed drive before worrying about adding one to the server.  

Test disk 0:1 with Online Diagnostics ... if it fails diagnostics, then replace it (maybe with the disk you are trying to put in now - if it is large enough).  If it passes diagnostics, then select Rebuild from the dropdown menu for that drive.

ok I was looking to add space to the c drive, extend that space out
0
 
PowerEdgeTechIT ConsultantCommented:
If, however, you ARE trying to replace that failed disk with this one (you mentioned earlier that you just wanted to "add" it to the server), then you can add it as a Hot Spare and it will begin to rebuild.
0
 
jamelessCommented:
Honestly this looks identical to the issue I mentioned above.  We tried everything to get it to rebuild.  The only way we got it to was by upgrading the firmware of our PERC controller.

PowerEdgeTechIT ConsultantCommented:
You need to fix your failed drive before you can add a drive to it.   As it stands, if disk 0 or 3 has an error, then you lose everything.

PowerEdgeTechIT ConsultantCommented:
There is no reason to update firmware until the basics have been attempted.

really guys If i need to repair that failed drive i should do so, but i was looking just to add more space to the c drive, im out

so i dont have that diagnosic software, should I just hit rebuid on the failed drive?

You can add a drive to your RAID 5, which is a different scenario than has been addressed so far in this thread, but you can't do it while the array is degraded.

PowerEdgeTechIT ConsultantCommented:
Also, simply adding a drive to your RAID 5 will not automatically fix your C: drive issue ... you will still need to repartition, possibly backing up/deleting/restoring partitions to do so, or paying $$$ for utilities that can do it while keeping data intact.

i clicked on rebuild on that failed drive
0
 
PowerEdgeTechIT ConsultantCommented:
Ok.  Did you test it?  If not, watch it ... if it fails again, then the drive is no good.  If it completes the rebuild (couple-several hours), then I would strongly recommend testing it before attempting to add a drive to your RAID 5.

After it rebuilds and passes diagnostics,  you can go to OMSA, Storage, PERC, Virtual Disks, and choose Reconfigure from the dropdown menu of Available Tasks for the RAID 5 - it will walk you through adding the drive.  This will also take several hours (how many depends on the size of your drives), then you can worry about partitioning.

drive rebuilt now, i have 3 drives reading online and my new one reading " ready", clicked assigned global hot swap on this on.. but im still not seeing any extra space available. All this is doing is adding a drive to the RAID 5 configuration, I need more space on the C drive, how can i achieve this, reformatting, repartitioning  and all of that isnt an option
0
 
PowerEdgeTechIT ConsultantCommented:
You don't assign it as a Hot Spare to add it to your RAID 5.  A Hot Spare is a drive sufficient to replace a drive in the RAID 5 in the event that one fails; it does not actively participate in the array, but only stands read to automatically rebuild if needed.

What you want to do is "reconfigure" your 3-disk RAID 5 to a 4-disk RAID 5 to add another drive's worth of space to the array.  As I described above, you can start the reconfigure:  "go to OMSA, Storage, PERC, Virtual Disks, and choose Reconfigure from the dropdown menu of Available Tasks for the RAID 5".

alright good deal, all drives are online now. Under device manager still do not the extra space. What do I need to do now?
0
 
PowerEdgeTechIT ConsultantCommented:
Device manager will not show disk space, and My Computer/Windows Explorer will only show formatted space.

Right-click [My] Computer, Manage, Storage, Disk Management ... you should see a black block of Unpartitioned Space at the end of your "disk".

charlestasseCommented:
This is a simple answer.
Based on what has been said already, you now have a 3 Drive Raid 5 that is online with a Hot Spare.

To increase the size of C: you need to re-size it by ensuring you have available disk space.

If you do not have any additional space on the Disk Array you will need to add more hard drives.

negative, i dont have that. Double checked, this what my OSMA says

PowerEdgeTechIT ConsultantCommented:
I also understood from your last comment that the drives (4) were all online, meaning you had completed the reconfigure.

ravenrx7Author Commented:
well thats what I was trying to acheive this whole time, was to add a drive for more space, not add a hot swap to a RAID

ravenrx7Author Commented:
I did complete the reconfigure

PowerEdgeTechIT ConsultantCommented:
I believe charles just misunderstood what you had done.

ravenrx7Author Commented:
so I've done the reconfigure, i dont know why i called it device manager, same area i guess, meant disk managment do not show anything different has far as available space.
0
 
PowerEdgeTechIT ConsultantCommented:
I know what you were trying to achieve (after some initial confusion from terms used), but I believe charles was confused because the last comment you had made stated that you had made your drive a hot-spare, which is why I gave the correct steps for reconfiguring again.

So, is the space in Disk Management then?

Rescan in Disk Management so that you see the current disk information that windows has

Highlight Disk Managment and then un the View Menu select Rescan Disks

Then post an image of what you have here
