• MD 1220 / PERC H800 - how Raid 1 virtual disks?

  Hello I'm trying to configure Raid 12 1 (two pairs disks) in my Inbox MD 1220 with PERC H800. I started with 12 discs as 12 virtual drives Raid 0 and have recently added 12 additional physical disks for a mirror. I am able to mirror 9 virtual disks but when I select my 9th virtual to the mirror, no drives appear as available. The other 3 drives are there in the 'ready' State, but manage to open or the BIOS configuration utility seem to be able to use them as candidates of mirror. My computer is running in a kind of limitation of Raid 1 with Cabinet / card? Operating system: Windows 2008 R2 Datacenter Open Manage 7.4 Latest firmware / drivers for PERC H800 thanks! Dan ouedraogo

  Hi Joey

  I just tried OMCleanup and reinstalled 7.4.  He exhibited the same symptoms showing is not the physical drives in the H800.  I can't find a download 7.2 but would be willing to try the previous versions.  A previous version of OM worked with the same controllers / speakers / computer, but I do not remember the version where I improved.  (I am an individual shop and am not very informed when it comes to managing open, its versions and how to install/uninstall).

  I can still kill the DSM SA connection Service by running a foolish occupation for the H800 report.  The report H700 works fine.

• PERC 710 add physical disks for RAID 5 virtual disk and keep data

  I think to set up a physical disk 4 RAID 5 array on my new PowerEdge T320.  That should give me enough space to last long.  I have two empty slots of HD.  If I need more space, later, I'll be able to add one or two additional physical disks without losing the data already on the virtual disk?  If so, how?  I don't see a way to do this in the manual of Perc 710.

  Thank you

  Andrew

  Yes, it is "doable" later.  This can be done in the PERC BIOS, but it can be done in OMSA (OpenManage Server Administrator) within the OS.

  One thing to keep in mind is the limit of 2 TB "floppy" Windows on BIOS systems compatible.  If you plan to 4x4TB disks in a RAID 10, that TB ~ 8 'disc' will be converted to the GPT and BIOS UEFI boot mode value.

• Single controller RAID, LUNs, virtual disk groups question does?

  Hi VMware Experts.

  I have 5 servers (each at full load with local SSDS 8 x 1 TB).

  I'm curious:

  1. If I configure raid 5 (I'll have 6 TB per host), how many LUNS / data warehouses should create? Is it important here? In any case, we still have controller raid just unique, right?
  2. If I use VSANS, is there a difference in the answer above? A data store for each host is probably correct? Or because the VSAN configuration: raid0 /passthrough better to create several data warehouses/LUN?
  3. Insights into the performance here?

  Thank you!

  1. Yes, it is ok, because you have no other choice.

  2. you can't do several stores data vsan. A single vsan by cluster data store is possible.

  No matter how many ssd\hdd for each host that you have.

• PowerEdge R720 virtual disk question

  Hi, our company has bought a Dell PowerEdge R720. I tried to use the lifecycle controller in RAID configuration. At the start, it has 3 500 GB SAS HARD drive, but I ordered 2 x 320 GB additional SAS being what I intend to do it, use the 2 x 320 GB like OS install as RAID 1 and RAID 5 on the default 3 x 500 GB, but for some reason any, whenever I have configure RAID , either on the two 320 or 3 x 500 GB, it shows just a virtual disk, 2 x 320 GB or 500 GB x 3, I see not two for RAID 1 and RAID 5 virtual disks. Am I missing something here? or I have to perform an extra step?

  Kind regards

  Jeff

  Hello Jeff,.

  If you try to install the operating system through the lifecycle controller method. You must have the latest lifecycle controller OS driver pack installed in your system. For the latest driver pack OS, please download from our support http://support.dell.com/ site by entering you service number and download OS Driver pack drivers.

  You can update the OS driver pack thorugh iDRAC GUI or through the lifecycle controller GUI and once after the OS driver pack update. When you try to deploy the operating system through the life cycle of the controller, you will appear on the list of supported operating systems and you can select the operating system you want to install by mounting the image operating system or DVD media connected to the system.

  Please let me know if you have any question.

  Thanks, Neeraj

• Re-create a virtual disk (RAID 1) of two existing drives

  After several power outages, my server Dell PowerEdge T110 ii starts plu. The virtual disk (RAID 1) has disappeared, but the two physical disks are still visible and a State of readiness.

  Is it possible to create a virtual disk Raid1 of two existing disk which was composed the original virtual disk without losing any data?

  If this is not possible, is there a way to recover the data (image) and re - create a new virtual disk?

  I hope someone can help me.

  I don't think, because the process would have initialized the disc, which formats.

• Cloning of a virtual disk before developing a RAID 5 system

  Hi all

  My apologies if this has been answered before, or there is a simple solution that I have not yet met.

  I have a Dell Poweredge 2900 with a Perc 6 / i RAID controller. I'll use OMSA to reconfigure a virtual disk RAID 5 I want to increase the storage of data on this drive, but I would like to the VD to backup before you go ahead and commit to reconfigure the disk (data stored on the VD is critical and I don't want anything to go wrong when the reconfiguration and lose all data).

  I have the RAID 5 VD on 4 discs and filled the other empty bays 4 identical drives and created a new VD on these new readers. Is it possible that I can use the BIOS RAID configuration or the OMSA to everything from the original to the new VD VD clone, or do I need a third party software?

  No, you need some sort of backup and imaging software.

• Reference Dell R610 RAID, virtual disk more problems of 1800 GB

  Hello community,

  I was frustrated by my attempt at installing VSphere 4.0 Update 2 (or 1) on a virtual disk on a SAS Perc 6, which is more than 1 800 GB in size and I was wondering if any of you have had similar experiences and how you have handled THIS.

  Unfortunately this system will use internal to the storage drive as it will be in a remote location.

  Any help is greatly appreciated

  Thank you

  Break your table into smaller pieces. ESX requires a minimum of about 10 GB, even if you can make bigger it. ESXi requires only 1 GB. Data warehouses may not be less than 2 TB. You may be able to use virtual disks raid based to break the table.

• Reduce the size of the virtual disk RAID 5

  I have Windows Server 2003 is installed on a virtual disk PERC H700 RAID-5. Total size of the disk is 5.5 TB. The problem is that WinServer 2003 cannot use the disk due to the MBR 2 TB limit (and I can't convert to GPT without destroy all partitions, which is what I try to avoid). Since 3.5 TB of drive space is unallocated (and reconciliations), is there a way to reduce the size of the virtual disk to remove this space which can not be used anyway? Then, I could by using the remaining capacity to create a new virtual disk that can be set up as GPT and access the space through it (or two new virtual drives 2 TB and 1.5 TB in size). I know that you can expand a virtual disk, but you can a shrink?

  No, you can develop most of the virtual drives, but you will not be able to reduce them.

  You will have to start on this subject, creating a VD less than 2 TB for boot/OS disk, then the rest can be used in an another VD.

• Reconfigure the virtual disk using OpenManage of RAID 0, RAID-5

  I apologize for the spacing.  I'm having a little wrong with this forum edit my post.

  My small business has had a T610 run for a few years with the following configuration:

  T610 Server

  PERC 6 / i controller

  4 physical disk 1 TB

  Virtual disk 0 size 1 800 GB RAID - 5

  Size of the virtual disk 1 992 GB RAID - 5

  Virtual Disk 1 was running Exchange and everything else on VD 0.

  Last weekend, I had a breakdown of table flat due to the failure of a damaged drive on Windows SBS 2008, who couldn't recover. When I contacted support Pro and got a new drive, I was told not to recreate the same virtual drives and use one.

  The local tech and I have been quite underlined and used the Perc 6 / I BIOS to recreate the exact configuration. Then, we had to use Backup Exec 2010 to restore the data. Somehow, we have selected by mistake instead of RAID 5 RAID-0 on recreation of the two virtual disks.

  So now, I have the following configuration in OpenManage:

  Virtual disk 0 size 1 800 GB RAID - 0

  Size of the virtual disk 1 992 GB RAID - 0

  I called Dell and gave instructions in OpenManage on how to reconfigure a virtual disk by adding a physical drive and conversion to RAID-5. My problem is reconfigure is not an option in the dropdown menu, I am told, because I have two virtual disks that have stripes.

  I have the ability to drive to go to 1 single virtual disk, given only Exchange is on the second and I can move, then unmold Virtual Disk 1. So my plan is:

  Full backup tape.

  Move Exchange off the drive sitting in virtual disk 1 to disk on virtual disk 0.

  Remove the virtual disk 1.

  Add a 5th physical HD.

  I hope at this point OpenManage will then give me the option in the drop-down list to reconfigure Virtual Disk 0.

  The option to Reconfigure in OpenManage will appear after that he sees only 1 virtual disk?

  Hello

  KRoy66

  The option to Reconfigure in OpenManage will appear after that he sees only 1 virtual disk?

  Yes, the ability to reconfigure should be available as soon as you remove the second table off readers. Technicians are you talked with correct you cannot reconfigure a table in slices.

  I know that you went through the entire process of relocation and restoration of backup, but it is preferable that do you it again. Let me explain why your table has been configured in this way, and why you may need to reinstall again.

  There are limits on the partition. To create a partition more of 2 TB, it must be TPG. In order to boot the system from a partition GPT Board must be set to UEFI mode. The problem you will encounter when trying to create a large RAID 5 is that you will not be able to use more than 2 TB of it. You create a new table in slices to use the extra space.

  If the system card is already set to UEFI mode then you should be able to convert the GPT partition and expand to necessary to hold account space. If you have installed the operating system with the system of administration established on the MBR can change in UEFI and conversion of GPT likely to cause BONE to be unstable if you are able to boot on it at all.

  I think you need to save yourself a lot of hassle and do this upgraded correctly. I know it will be a lot more time to restart, but you should set the UEFI boot mode, remove the two RAID 0, create the new large RAID 5, reinstall the OS and then restore the backup.

  Do it right now probably will save you a lot of time.

  Thank you

• Reference Dell MD3220 virtual disk - hot spare in use

  We have a Dell MD3220.  one of the hard drives was taken out by an end-user trying to exchange a defective disc.

  Hello, GalaxyTechService.

  It is perhaps not as complicated as it may seem, in fact. There is a wizard that you can use to return the disk to the raid set. Right-click the affected virtual disk and select 'Replace physical disk' and use the wizard that opens.

  In the upper area will be "missing disks", and in the lower field will be options available to replace them.

  Then just follow the steps.

  Let me know how it goes.

• MD3000 cannot change virtual disk ownership / preffered path - ERROR 29

  Current configuration

  PowerVault MD3000 (deleted by the moderator) - attached to two servers PowerEdge R610 using Dell SAS 5/e card in each r610. The R610s act as a host ESX VMWare ESXi 5.5.0

  We have created multiple LUNS on the storage array and noticed that traffice all happening through a RAID controller or another module (and it seems to me not change without prompting when you look at the storage Bay). I turned off a two different virtual machines to try to change the path and had an error with a certain delay - I stuck this error below. I also tried to redistribute virtual disks tab the MDSM software nothing works support.

  By reading, it seems that the LUN should be attributed to a particular raid controller before all I / 0, but I still feel like're missing us something as to why we cannot distribute the traffic properly.

  According to some records for a MD3200 -.

  "If the host has a path of data unique to the MD, the virtual disk storage array.
  must be owned by the controller to which the host is connected.
  That's what we're trying to accomplish. I don't know if the hosts are to be physically detached from the SAN, or if there is a bit of software to fail us.

  Hello MrRedPants,

  Since you are using a configuration not redundant you will have problems trying to modify the paths between the controllers since the two hosts have only a single connection to the MD3000.  What you could do if possible is to get 2 more SAS cables & connect ports second on the MD to RAID opposite that the host is currently connected to.

  Now, if this isn't an option so that you can make is to have 2 disk groups and assign the virtual disks / LUNS that are connected to each host in their own disk group.  If you go to each host their own groups of disks, then you will need to stop the e/s as you move the Ramdisk to the new group of disks so that you want to discard any data loss.

  Please let us know if you have any other questions.

• initializing virtual disks

  I have a powervault MD1000 (Bay raid storage) connected to a backup server. It is set up with 3 virtual drives that each use 2 terabytes of storage in RAID 5 from our range of 8 physical disks.

  I had to replace two of the physical drives, and I need to initialize my virtual disks. In the Perc 6/E management screen VD, I can select the virtual disks (that show in red) and press F2 to display the operations, but the initialization button is dimmed and I can't select it. In the PD management screen, the new drives show as ready.

  How do I initialize my virtual drives? Should I delete them and create new virtual disks? It's my first time doing this, so please bear with me. Any help would be appreciated.

  I just updated the firmware of the 6th Perc to version 6.3.3 - 0002, which has a rep to support Dell recommended that I do, if this is useful.

  After you remove virtual drives, I was able to create a new virtual disk and initialize it. It seems that I just have to build the virtual disks from scratch.

  Thank you for your time.

• Max MD3000 virtual disk size

  Can how big I grow a virtual disk?  As above, I have two servers Dell PE in a cluster failover with Windows 2008R2 Ent. The MD300 contains two Virtual disks 1 x 50 GB of disk as a cluster quorum and 1 x 4TB which holds virtual machines. I would add 2 TB for the largest virtual disk; that would be appropriate?

  The only limit to the size of the virtual disk on a series of Dell's MD3k is the maximum number of physical drives in a single group. For raid 5, it's 30, RAID 10, is 44 and for raid 0 is 45.

  When you configure a cluster, I usually use a Quorum GB 2. If it is an installation of hyper-v I then use 2 disks or more virtual to spread the i/o load. If not for hyper-v, then the structure of the virtual disk depends on the needs of the application and storage.
