I was in the process of verifying a dead drive bay on a Dell PowerEdge 3010.
When we arrived onsite we found that all 4 drives were plugged in, but only 3 drives were active. We logged into the server to get specs. We then logged into the RAID utility to learn more about RAID configuration. Found that Drive 4 was not active or noting in RAID utility. Then pulled 3rd and 4th drives to test drive 4 in bay 3. Drive 4 did not show active. Pulled drive 4 from bay 3 and replaced drive 3. Started rebuild on drive 3. Noted the time it took to locate drive 3, then attempted to change drive 2 to test drive 4 a second time as drive 2 was showing offline. Plugged in drive 4 and waited for it to show up. Drive 4 came on in bay 2. Then replaced all drives to original locations. Noticed problem with drive 3 being “Foreign.” Stopped there

How do I break RAID 1 mirror on Poweredge 2600
User has a PE2600 with 2 drives RAID 1 Stripes 2. I was called in because the server won't boot. Both drives were offline. I forced drive 1 to go online and it starts booting into Windows 2000 server but goes to a blue screen with a message that if it happens again to try running a chkdsk /F.
User cannot find their windows CD so that is not an option. I forced drive 1 offline and drive 0 online and it boots up just fine and I can login. Problem is the event logs show dates before I booted up as being over a year ago. I'm guessing that drive 0 went offline last year and they've been running just off of drive 1.
So I'm thinking if I break the mirror and boot up off of drive 0 then I can look at drive 1 as a second drive and pull their data off. Does this sound right?

VRTX Dual PERC 8 write-through only?
Is it really true that a VRTX with the Dual PERC 8 controllers cannot do write-back caching?
We have a new VRTX and got the dual controllers, have it set up as a Server 2012 Failover Cluster, and have migrated several VMs already to it. But we're getting reduced performance from our virtualized database server, and that got me to thinking about the write cache policy. Could this be my problem? Is there a way to increase write performance on the array?

CTIO and cachecade, Perc710, Perc710P 1 gig - Are they mutually exclusive?
Its my understanding that you can enable CTIO OR cachecade but not both. There is a disclaimer for cachecade that specifies the required settings and these would disable the use of CTIO.
I have read many posts where cachecade drives are being created and CTIO enabled, but its my understanding that the cachecade drive can be created in a CTIO deployment but it wont be used due to a conflict in settings.
I am seeking some supporting documentation regarding this conundrum.
Thanks!

PE C1100 with a PERC 6/i, do I need a battery?
I have a poweredge C1100 server. Purchased a PERC 6/i RAID controller. It did not come with a battery or a battery cable. Questions are:
1. Is the PERC 6/i able to be configured with a battery?
2. If yes, do I need to also purchase the RAID battery bay, that the server did noes not have?
3. Where can I purchase all these pieces?

Add new disks
We bough some new SSD disk for Dell R720
The server already had 4 SSD disks 200GB each that we had created a RAID 10 partition from.
What are the possiblities for me to present the new 6 x 400GB SSD disks to the server
I do not want to lose any data that i already have on the server.
XenServer 6.2 is installed on the existing disks.
I have attached the image of current config.
Also one thing i noticed after adding the new Dsiks , they did show green on the server
B ut when i looked into the iDRAC , i only see the 4 and not the new 6 disks.
Do i have to restart.
Are they not hot Pluggable.

Looking to replace an older RAID controller (UCS-61) with a newer Perc 5i (UCP-51) in a PowerEdge r610...
Hi everyone,
I am looking to get RAID 5 capabilities in an old R610 we have laying around. The new controller appears to be compatible with the server, and is known good. Every time I boot the server with the new Perc 5i card it gives me:
"Invalid pcie card found in the internal storage slot.
System Halted!"
Is there a step to this process that I am missing? This is my first time trying to do anything like this, and am getting beat up. If I put the old controller back in or no controller at all it boots without problem. I have updated the BIOS to Dell Server BIOS R610 Version 6.4.0.
Any advice would be greatly appreciated.

Adding space to a server
I have an R710 with a PERC6/I controller running exsi 4.1.0. Storage as purchased was 8 200GB drives. In order to accommodate another virtual machine 3 larger drives were purchased and swapped in one at a time to maintain the old array and allow space for a new logical drive in the empty space.
What would be the best way to accomplish this?

Does Dell PowerEdge Server's firmware supports booting ISO image stored on the local Hard Drive ?
Hi
I am using Dell PowerEdge 2950 servers.
Can I boot my PC through a "Bootable ISO image" stored on my Local hard drive? So that I need not to burn a CD/DVD as Bootable media.
Just like in a VMWare machine, an Acronics Bootable ISO image is stored on the Local Hard drive. By selecting option "Connect/Disconnect the CD/DVD Device of Virtual Machine -> Connect to ISO image on Local Disc, when you boot your machine, system automatically load the Acronics. I need not to insert a Bootable media into the PC.
Is this possible technique be implemented in a non-virtualized environment without installing any additionla software ? Just copy the bootable ISO image into the local machine and do the needful settings in CMOS Setup or anywhere it is applicable.
I am working as a System Test Enginer. I can't take a change to load any other 3rd party software to make this work on my test system. So want to know is this possible. I am using Windows 2008 R2 Standard SP1 & Windows 7 Professional SP1 OS.
Thanks.

T110 raid down.
Hi,
I have a T110. This morning the power went out in the building and the server would not boot.
The server has a PERC S100 with 4 500 GB hard drives. Currently Drive 00 says offline, 01 Ready, 02 online, 03 online.
From what I understand I have a bad drive on 00 and a the ready drive lost its way. Can I use 01 to rebuild my raid?
Thanks in advanced

Fault: BP Drive 0: Drive Slot sensor for BP, drive fault was asserted
Hello,
we have 2 Poweredge R810 with PERC H700 Integrated RAID controller. I am trying to install SATA hard drives. All drives i try actually work but i get a fault on the LCD and in iDRAC saying:
BP Drive 0: Drive Slot sensor for BP, drive fault was asserted
This fault moves with the hard drives through all drive bays and also on the 2nd server the same. i have tried these drives:
Hitachi HTS54322 232GiB
Hitachi HTS54503 298GiB
WDC WD10SPCX-55H 931GiB
if i google the fault message nothing come up. I had also asked the supplier if i would need an interpose but apparently thats only needed for older servers. anyone have a clue what this fault means and how i can fix it ? just to say it again, the drives DO actually work. here the output from the status report:
# megaraidsas-status
-- Arrays informations --
-- ID | Type | Size | Status
a0d0 | RAID 0 | 297GiB | optimal
a0d1 | RAID 0 | 931GiB | optimal

-- ID | Model | Status | Warnings
a0e*s0 | ATA Hitachi HTS54503 298GiB | online
a0e*s1 | ATA WDC WD10SPCX-55H 931GiB | online
I am running Debian 7.5 on the servers. Using the RAID utilities from here to display status information on the CLI:
would be great if anyone could shed some light on this.
Kind Regards

T300 with SAS 6 host bus adapter configured for Raid-1, one of the 1TB HDDs died.
I pulled one of the 1TB drives from one of the other Dell servers and am concerned about harming the raid configuration or breaking the pairing. Where can I go to see exactly what I need to do and exactly what I don't to sync the new drive. I'm running Windows Server 2003 R2 on this old server. Also, while these drives are identical size, one says KA02 on it and the says MA08, whatever that means.

Windows Server 2008 won't accept LSI Logic PERC 4e/Di Driver
Hello all.
This is a problem that has been posted before, but the solutions given have not worked for me.
I have a Dell PowerEdge 6850 with a PERC 4e/Di RAID controller firmware level 5B2D. I want to install Windows Server 2008 r2. Microsoft says that the driver i need has been removed from windows server 2008 r2. So i went to Dell and there is a LSI Logic PERC 4e Driver package for this problem.
This is the real problem tho when try to install windows server 2008 r2 it says it cant find the local drive and prompted for the drivers, but when it tries to install them it says no new drives found.
There is 5 SCSI hdds setup in a RAID 5 configuration with only one local drive. Also I am installing windows server 2008 r2 from USB drive if that makes any difference.
Thanks for the help.

PowerEdge 840 Raid Drives No Recognized
So all the sudden both Raid drives are not recognized. I go to Ctrl + M shows as failed.
I have RH478 Backplan and e2k-ucs-51 (b) Raid Card
Both drives read fine connecting to external USB enclosure so all data are in tact.
Just wondering is it the Backplan or the raid card itself? or something else I am missing?
Also I tried connecting the hard drive to the sata and its rebooting constantly I am assuming because its looking for raid drivers and not sata.
Thank You

write-through caching policy Fault Tolerant Shared PERC 8 big performance hit / very poor performance
Hi,
I have been struggling with a storage performance issue for a few months. I found out that the culprit in this performance hit, is the Fault Tolerant Shared PERC 8 in the VRTX. In this configuration you are bound to the write-through caching policy, which is currently performing very bad.
Because of this big performance hit on the storage (caused by the caching policy) I had the following problems:
- Poor performance of (HyperV) VM's
- Poor copy performance (copying big files within the same volume 70MB/s max)
- Unable to make a backup of the VM's using either Veeam B&R 7 or Backup Exec 2014 RTM (backup and VSS are related)
- VSS time-out errors (0x8000ffff- Catastrophic failure)
- Checkpoint creation of a VM took about 2 minutes
The release notes of the latest firmware (23.8.12-0061) for the SPERC 8 state:
Firmware supports VRTX running with single SPERC8 controller;
- Write-back cache is enabled for VDs.
- Does not have high availability capability
Firmware supports VRTX running with dual SPERC8 controller;
- High availability capability present (Both SPERC8 needs to be connected to expanders)
- One of the controllers is active and the other is passive
- Write-back cache is disabled for VDs; only option for write cache is Write Through.
To downgrade from a dual controller to a single controller, I removed the second SPERC8 controller, removed the second expander, re-cabled the SAS connections and downgraded the chassis to 1.25. Just removing the controller and expander wasn't enough, because then I still was unable to set "write-back" as caching policy. As soon as I downgraded to 1.25 I was able to set write-back as caching policy.
With the single controller configuration, the storage performance is as it should be. All the earlier mentioned problems are gone:
- (HyperV) VM's perform excellent
- copy performance is excellent (copying big files within the same volume around 650MB/s max)
- Backup actually works (backup and VSS are related)
- No more VSS time-out errors (0x8000ffff- Catastrophic failure)
- Checkpoint creation of a VM took about 4 seconds
From this experience I currently strongly advise to not go for the dual SPERC8 configuration and stick with the single configuration. Hopefully a firmware update will solve this performance issue, because at the moment having the dual / fault tolerant SPERC 8 configuration with this very poor storage performance makes no sense at all. Yeah, you're fault tolerant... but no backup and bad performing VM's aren't really a good option in a production environment I think...
Or might there be an essential setting I am missing for the write through setup? (I have tried different settings already...)
Below are the benchmarks made using Atto. The difference is tremendous! Funny fact: while doing the benchmark with the write back policy enabled, the virtual disk was still in its background initialization process, and with the write through it was not.
NOTE: Both VD's were configured as RAID6

Retag Drives on DELL PERC 6/I integrated RAID card
We have a DELL 2950 that has two 6 drive total set up as RAID1 and is the boot drive. The other four drives were set up as RAID5. Two of the drives on the RAID5 did not get reseated all the way and the configuration came up as Foreign. The only option we had was to clear configuration. We did that and know the Foreign option is greyed out and will not provide the import option. I have seen some discussion that a retag of the drives may work to get the information. Is the an option. Below is the exported log file.
