Move RAID5 array to different server

August 22, 2016, 11:24 am

Had a RAID failure on an old PE2850 ; looked like two disks failing at once, which makes me suspect the PERC, not the disks - especially because I moved the disks as a unit to another PE2850 and was able to mount it as a second RAID array (OS of new server on RAID1 disks 0 and 1, this array disks 2-5) and it recognized the array. 

However, I can't mount it as an Windows partition.  I boot the OS on the new server and disk manager recognizes there is a disk there, but I can't use it unless I format it, which will defeat the purpose of the whole activity, which at this point is to somehow pull useful data off the array. 

Can anybody suggest a way to get that array recognized by a new server or PERC card or something?

Brand new T330 Raid 1 Test

Hello.

We just got a brand new Dell T330, configured with RAID 1 using a PERC H330 controller. There are 2 HD SATA 500 GB. They are installed in bay 0 and 1.

I have installed Windows server 2012 R2. There a 2 partitions: C: and D.

I decided to perform a test to see what happens when a HD fails:

- A wrote a small file of the C partition and an other small file in the D partition.

- Then I removed the drive in Bay 1. I was able to see both file in the C and D partitions.

- I reinserted the drive in bay 1.

- Then I removed the HD from bay 0:  The while system hung and stopped with error message and rebooted, tried to reboot...tryed to reboot...

...

I reinserted the HD in bay 0: but the system does not boot anymore.

what is wrong? How to make the new server work again? Was that the expected behavior when HD is removed from bay 0. I thought that either drives could be removed and the system would keep working..

Help me please!

Thanks

Gilles

I am currently working on an Power Edge M820 that has local storage hard drives installed.  Problem is the lights on the hard drives are inoperative, and I need access to, and the ability to download the Raid Logs from the Server.  Is it possible to gain access and download the logs from the Raid Controller itself, and if so how.  The hard drives are arranged as two physical disks, forming 1 Virtual Drive.

PowerEdge T310 - installing second drive as raid1 with dell server administrator software?

Hi all,

Quick question - we have a PowerEdge T310 with one drive in it. We want to install a second drive and put them in raid1. Questions:

  1. Can we use dell server administrator software to do this?
  2. Will this erase the volume on the current drive?

In a perfect scenario, we simply want to install the second drive, set them up as raid 1 and call it a day.

Thank you for any tips!

We had a healthy raid 5 array on a Dell R710 all of the sudden the array disappeared from my computer. When I try to initialize the disk in computer I get the error "The system cannot find the file specified"

This is on Disk 1. Disk 0 is still fully operational and the system boots.

Any help is greatly appreciated.

R710 RAID 5 Perc 6/i shows 2 missing drives and will not boot - recoverable?

August 23, 2016, 12:15 pm

I have a Dell R710 with 6 drives in RAID 5. One of the drives failed (05) and was replaced with a new, clean drive. After installing I checked the RAID config under "PD Mgmt". The new drive was showing as showing "Ready", but then drive 04 was now showing as "Foriegn". I cleared the foreign config, and then both drives showed as Ready. Couldn't get past that point. 

I rebooted the server and now it will not boot at all. Comes up with "There are offline or missing virtual drives with preserved cache. Please check the cables and ensure that all drives are present. Press any key to enter the configuration utility."

I entered the config utility. Under "VD Mgmt" Virtual Disk 0 is red. Hitting F2 gives only the option to "Delete VD" or see Properties.

When I expand "Physical Disks" drive 04 and 05 are now just listed as Missing. 

I now go into "PD Mgmt" page and the drives show as Ready.

Selecting F2 for either drive only gives the option for "LED Blinking" and "Make Global HS".

So, is there anyway to recover and/or re-add these two drives to the RAID 5 array?

Dell 1950 Crashing Intermittently Event ID 2336

August 24, 2016, 7:31 am

I have a old PowerEdge 1950 Server that I'm trying to repurpose.  I have gone through and attempted to make sure that the BIOS and any underlying hardware firmware have been updated.  I've installed Server 2012 R2 and there is an AV running.  When the AV does a daily quick scan the server will intermittently crash and records the following errors.

Event ID 41 - Kernel Power

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Event ID 2336 - Server Administrator

Controller event log: Fatal firmware error: Driver detected possible FW hang, halting FW.
: Controller 0 (PERC 6/i Integrated)

Controller event log: Fatal firmware error: Line 3622 in ../../raid/1078dma.c
: Controller 0 (PERC 6/i Integrated)

I've tried contacting the AV vendor and they weren't much help in resolving this issue.  I have the same AV running on other servers with 2012 R2 and haven't had any similar issues.  At the moment I'm not sure if the AV is causing the server to crash or if I've missed updating something on the hardware level that's causing a conflict.

Any suggestions are appreciated.

H700 dropping Cheetah drives

I have a C2100 with H700 on newest firmware. I have an issue where all drives in the server will be marked as failed at some point - the drives work fine in any other system (no other H700 systems). Initially I had them in RAID1 arrays, but the arrays would drop both drives. Then I tried setting up each drive as RAID0 with software mirroring, and the same thing is occurring.

Drives:

6x Seagate ST3300655SS
6x Western Digital WD50EFRX


These all get marked as failed at random times (days/weeks), I believe at times of heavy disk activity. I have to physically remove and reinstall the drives to get them to reset. Ideas? I'd think at least the Cheetahs would work flawlessly...

change boot order of array with SAS 6/iR Adapter RAID Controller

Hi, i have a server running with a SAS 6/iR Adapter RAID Controller (firmware 00.25.47.00.06.22.03.00) and created a second array.

It seems the controller only boots the first array. I can't find any option to select the other array. I have searched in the BIOS, the boot menu (F11) and also in the configuration utility of the RAID card. but no luck.

I hope this is possible.

Poor performance PERC H710P

August 24, 2016, 6:39 pm

I am experiencing a serious performance issue with a PERC H710P with 2 RAID 1 Mirrors. 

Sys config:

2 Intel Xeon E5-2620 CPU Running @ 2000MHz

32GB RAM

Mirror 1 

2 - 2TB SAS Drives

Mirror 2

2 - 2TB SAS Drives

Windows SBS 2011 Server.

With no users connected to the server, I run ParkDale (a HDD read / write testing prog) on mirror 1 (contains the OS and all Windows functions). On the first pass I get a Sequential write of 350 -400 MB/sec. Seq Read 400 -600MB / sec. Random Write 35 - 45  MB/sec Random Read 40 -55 MB / Sec. After the test completes I immediately run it again and typically the Seq Read / Write are cut in half (sometimes the Seq Write will drop below 100MB / Sec.

Running the same test on the 2nd mirror (contains the files for a company wide CRM prog) the numbers are always lower (Seq Write 100 - 200 MB / Sec Seq Read 250 - 400 MB / Sec); and an immediate re-running results in the same performance drop.

Within the CRM is a diagnostic program. This tests the processor and also the disk performance. While it doesn't list hard numbers for test results it does show a bar graph. On the over all tests, the server performs about mid-range - if I were to convert this to a scale of one to 10 - (1 being good); typically fast would be 2; typically slow would be 6 and this server is a 4. On the hard drive test; again 1 to 10 (1 being good) typically fast would be 2 typically slow would be 6 and this server would be 20 (the bar goes off the edge of the test page).

I have updated the FW on the RAID controller, both virtual disks have cache enabled, and are set to write-back. The server has all available updates. I have also stopped all SQL services, disconnected the server from the network and stopped every service I could for testing but nothing seems to make a difference.

Any ideas? Any suggestions? Am I missing something?

Slow writes PERC H700 and Samsung 850 PRO SSD

August 25, 2016, 8:05 am

I've seen several posts regarding this, but haven't seen a solution.

I have some R710 servers with H700 controllers. I've installed Samsung 1TB 850 Pro SSDs and seeing very slow write performance compared to other SSDs tested within a same box, just slow in general. Samsung SSDs are doing ~500 MB/s in both directions when connected to standalone desktop, but ~500 MB/s read and ~45 MB/s writes when connected to a server.

1. 1x SSD in RAID 0 - No redundancy, just to test performance. I've tried every combination of write-back cache setting and read ahead setting possible (enabled, disabled) and never got more than ~45 MB/s writes.

2. 6x SSDs in RAID 5 with all possible combinations of write-back cache never getting more than ~110 MB/s writes.

3. 6x SSDs in RAID 10 again all possible settings of write-back cache - ~140MB/s.

Lastly I've installed 120 GB Intel SSDs and got over 400 MB/s in both directions regardless of the RAID or caching.

What is the problem with H700 controllers and Samsung SSDs? Does anyone know how to fix it?

Any other R710 compatible controller that don't have this problem? JBOD capable, maybe? I've also tried an off the shelf PCIe controller without any luck (backplane compatibility issues or some sort)

Thanks in advance.

P.S.

Controller is on a latest firmware along with BIOS and all the other components. Used Dell repository manager iDRAC discovery and bootable ISO to update everything.

Samsung SSDs are on a latest firmware as well.

Hi, i have 2 samsung 750 500gb evo's SSD's and 2 WD red 3TB hard drives want to run in raid, I have the 2 WD red hard drives attached to sata0 and sata1 ports on the motherboard, the dvd on sata3.  I bought 2 "Best Compute M.2 PCIe SSD to PCIe 3.0 x4 and M.2 SATA SSD to SATA III Adapter Card s" and installed them in the expansion slots 1 and 4.  In the bios the computer doesn't recognize the cards, says all slots empty.  it recognizes the WD reds but of course not the SSD's.  The SSD drives work tried them in sata0 and sata1.  what am i doing wrong?  i want raid 1 to mirror the drives.  My thinking is  an older motherboard the SSD's run faster on the expansion cards.  nothing in manuals says the speed.  thanks

dell sas 5/iR raid 1 repair question

August 29, 2016, 8:08 pm

Hello,

Have an old power edge 840 running a raid 1 with two 750gb drives, one has failed. Have a bit of confusion about part 1 that Daniel referenced:

According to DELL-Daniel My on another thread about this controller, he said:


You will want to boot into the SAS5 controller BIOS and OFFLINE/FORCE OFFLINE the drive you are replacing before you swap it out. If you do not force the drive offline then when the controller boots up with the blank drive it will likely wipe all of the data across the array. The problem is that the controller will not know the drive is replaced and it will try to make the two drives identical, wiping out the data.

Offline the drive in the controller BIOS or OpenManage Server Administrator/Storage Manager
Shut down the server and swap out the drive
Boot up the server and set the new drive as a hot spare through the controller BIOS or OMSA
The drive will start rebuilding
=====

I found a great step-by-step article but it conflicts slightly with what Daniel says so want to make sure I understand before attempting these steps:

sheldonsblog.com/index.php/rebuild-degraded-raid-mirror-on-dell-poweredge-840-with-sas5ir-controller/

1) -When- do I remove the missing drive (bad drive)? Do I boot into bios as Daniel said and force the "missing" (bad) drive to show as offline, shut down the system, then replace it with the new blank drive (is it possible to offline drives in the raid bios on this controller, if so, how)?

2) Or do I simply identify what drive is bad in the raid controller bios (labelled as "missing"), shut down the server, remove the bad drive, put in the new blank one, boot up & re-enter bios using ctrl+C, set the blank drive as a hot spare, and wait till it's 100% resynced as suggested in the sheldon guide?

I've not seen anything in the official Dell documentation about setting 1 of the 2 drives in the virtual disk (raid 1 array) as offline. Obviously on reboot, I don't want it to start syncing the new blank drive over the existing good drive, wiping out my data. Will have a backup beforehand. Doesn't the raid controller have info it references and the "degraded" drive have headers referencing the raid 1 array? Shouldn't it know not to sync the blank drive (without raid headers) to the drive with "raid headers"?

As such, can't I power down, remove the bad drive, put in the good one, boot into bios again, set the new blank as hot spare and wait till the sync is finished?

I know anything can happen and I have backups but trying to avoid wiping things out by accident.

Thank you.
