Undetected RAID array

I use a HP DL180 G5 equipped of an E200 HP controller.

I built two RAID arrays using the E200 controller

1 65 GB hard drive

4 HDDs of 750 GB in RAID 5

I was able to successfully install ESXi 4.1 and everything seems to work without problems.  Except that I am unable to see the matrix RAID 2 to.  I am able to see the 1 65 GB drive, because that's where ESXi is installed.  But I can't seem to find the matrix RAID 2 to anywhere.

I tried to do a new analysis of all storage cards, but it is not always see it.  I tried to rebuild RAID 5, but it is not always see it.

When you run fdisk-l on the tech support console it does not show the RAID 5 array anywhere. I also ran lspci and it does not detect the Smart Array E200 mass storage, but it does not detect the RAID array.  DF not to see no more.

I don't know where to go from here.

What are the troubleshooting steps I can go through to find the missing RAID array?  I'm assuming that they will have to be performed from the CLI.

I have not tried to install 4 independent labels still to see if we can see them or not.  I'm sure that the disks are always good as I was running this server as a target iSCSI using Solaris 10 until a few weeks before.

Welcome to the community,

ESX has a limitation for the disk/LUN 2 TB sizes less than 512 bytes. Assuming that you are running the latest firmware on the E200 and the upgrade of cache installed (required for RAID5) I recommend you remove the 65GB disk and create a RAID5 with 4 x 750GB disks. Since the RAID 5 create 3 logical volumes, for ESXi and 2 x 10 GB ~ 1 TB for VMFS data storage. You need to do this, use the ACU on the SmartStart CD utility.

See http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00688683/c00688683.pdf for more details E200

  • OptiPlex 7020 and RAID array

    Greetings.

    I bought an Optiplex 7020 and controller card SATA referenced in this post after you speak with a representative and come far from believing the 7020 and the SATA controller card combination would allow me to set up a RAID 1 array. I bought both the 7020 and the controller Dell card.

    However, after several conversations with the Dell and Technical Support Technical Support Startech, I'm still not able to get this working. I am able to enter in the configuration menu of controller card at startup in addition to being able to access the system BIOS. The BIOS shows 'Mass Storage' assigned to the PCI Express slot (as it should), but complains without hard drive being found when I try to start.

    Just for clarity: I'm not trying to use a built-in RAID configuration and try instead to use a controller card to take care of the RAID array. So I am (perhaps erroneous) belief that the 'RAID ON' in the BIOS setting is unimportant because the controller card takes care of the RAID array. BTW: My BIOS is not a parameter "RAID ON". I say just that to prevent an answering machine to take me on the way to the RAID configuration integrated. The 7020 does not come with built-in RAID.

    In fact, this Dell page said I need to "buy additional hardware", which is exactly what I did when I bought the controller card - or at least I thought.

    So the questions are: what should I do to be able to get my Optiplex 7020 to mirror the first drive on a second so that the second is bootable immediately in case one breaks down?  Do I need a software solution instead? Do I need extra hardware yet?

    Thanks in advance!

    If this card requires a driver, so it is probably not responsible until Windows loads BIOS will not be able to see the drives connected on this card to boot from one of them.

    And according to the Manual, the startup options are:

    To specify the order in which the computer attempts to find an operating system. The options are:

    1. Floppy drive
    2. WDC WD2500AAKX-75U6AA0
    3. USB storage device
    4. CD/DVD/CD-RW drive
    5. Integrated NETWORK interface

    Therefore, there is no option to say BIOS to get a boot on PCI - e drive.

    That said, it is made reference to the Intel RAID controller in the manual, which suggests it could work with this system.

    Win 8/8.1 and win 10, there is a built-in utility called "storage space" to create a mirror. Two drives must be connected to the SATA ports on the motherboard and probably identical in size. So give that a try...

  • Data store missing after the reconstruction of the raid array

    One of the players in my raid array has failed a few days ago.

    I had a spare drive in the table so the controller immediately began the process of rebuilding and all servers were running throughout.

    When the reconstruction has been completed (I checked this via the user interface of raid array and the newspaper), I had to stop the server to remove disc defective (not replaceable chassis hot) and when I restarted the server, the data on the raid array store isn't there anymore.  I also checked through the raid controller interface that I removed the (defective) drive and that the table was always in a ready state when he came.

    In vsphere client, when I click on the storage... Add link, the server sees the material but if I click then it tells me that it will be re - format the volume.  See attachment.  I have most certainly does not take the next step and reformat.  Simply, I took the screenshot and regularized.

    I found these instructions, but they are for an older version of ESXi and am unsure if they are correct for ESXi 6.0.0 338124

    VMware KB: Lack of data store after the reconstruction of the RAID disk/LUN

    Here are the steps I should follow?

    If these aren't the right instructions can you tell me the version which is for ESXi 6.0.0 338124 that I couldn't find anything either.

    Thank you

    Hi ThompsG,

    Yes, there are two data stores for the virtual machine located on the RAID array.  The virtual machine itself was stored in a different data store that was not in the raid array.

    I spent about 48 hours last week, including this morning, trying to coax ESXi recognizing volumes, with no luck.  Finally, I gave up and I removed the virtual computer hard drives that were on the corrupt data store.  Then the virtual machine came without problem.

    Finally, since I have everything on these 2 volumes backed up to a cloud provider, I have recreated the two data stores in the raid array and began the restoration process. It is currently running and has about 16 days left to go.

  • After a failed raid array recovery my data store is missing

    Hi all

    I'm under ESXi at home, but I have a problem with that I need help

    First of all, let me start with the specs:

    ESXI: 5.1.0,799733

    RAID Controller: Adaptec 6805 (driver of the community with the support)

    Configuration of RAID: RAID 5 12,71 TB of disk

    I had some problems with my RAID controller which I solved it using the Adaptec article: a table failed can be recovered? I ended up drop the table and re-create it.

    The RAID array is now in OPTIMUM condition, so I started ESXi and connected using vSphere to find all my virtual machines as unknown (Inaccessible).

    I started googling and found some information, but nothing so far to solve this problem.

    I tried info from these links:

  • Restore virtual machines after building the new RAID array

    Hi all

    I am new to the virtual machines, so I'm sorry for the newbie question. Currently, I have a HP ML350 G6 ESXi 5.0.0 running on 4 GB Flash hosting SD cards two virtual machines and licenses for 5 Essentials vSphere and vCenter Server 5 Essentials. I also have a RAID5 configuration with drives SAS 146 GB (6). I intend to remove all six readers and their replacement by 300 GB disks and build a RAID6 array. My question is, what would be the best practice to move the two VMS in the current RAID array to the new RAID array? Wouldn't be also simple to make backups of virtual machines or clones, exchanging the readers, the new array of construction and restoring virtual machines? If someone could point me in the right direction would be great!

    Thank you all!

    Personally, I would go with backup & restore. In addition, use the downtime to upgrade the firmware of the host (HP published recently a few critical fixes on the RAID controller and some models of HARD drive).

    What I would do - to avoid any problem - is to remove the host ESXi, vCenter, replace disks, update the firmware, re - install ESXi and as final step add the host to vCenter again.

  • Install ESXi cannot see the RAID array

    I tried to install ESXi 5.1 on a HP Proliant Dl160 G6, with 4 hard drives of 2 TB in RAID 1 + 0 array, using a HP b110i controller. When it comes time to select the installation media ESXi to, the installer sees the 4 physical disks, rather than the logical disk that I created with the controller.

    The b110i is a RAID controller-based software that does not support the ESXi.  As you have noticed it will not recognize the individual disks and it work perfectly with them as individual disks.  But if you are looking for a RAID array, you need to add another RAID controller.

    One of the major downfalls of Aperture is that it shows you where are your pictures. They always favored it as a feature (even as a ' new paradigm'), but it's not so wonderful when you need to do something about Apple never intended. Then, it sounds really like it led to you not knowing where your files or files that correspond to which elements of the UI opening. I suggest that you need to nail for yourself - images from Aperture to right click and choose Show in Finder, until you know where everything is.

    Otherwise, make sure you have plenty of available disk space, stop asking questions and just see what happens when you run plugin import LR with the options I suggested. It won't damage the opening.

  • Ideal for RAID array

    Because have a new video workstation built last autumn I used installer disk hard next five:

    C: / OS & programs

    D: / sound & video Media & CS5Projects

    E: / swap file & media Cache

    F: / Previews and exports

    H: / other multimedia files (Photoshop, and al.)

    This week I pick up a controller from Areca ARC-1880ix-16. With it, I will implement an array of RAID3 eight discs with a hot swap.

    I tend to simply set up a unique folder for every video project that will contain all files previously stored on drives D, E and F. Before that, however, I want to solicit the comments or suggestions of others using RAID arrays.

    The IMO = Im my opinion. See your the Internet Dictionary

    The disk performance for the reader where export is stored is not very critical on export. CPU/GPU/memory is the usual bottleneck and exporting to: keep the fill rate on your lower raid, that you access two drives (raid and (H) at the same time instead of one (raid).

    Start the BIOS of the controller (CTRL-C)

    Select the controller

    This will bring you to the adapter properties window.

    Use the arrow keys to highlight and select Properties RAID, press on enter.

    This brings you to the window again select array Type, there is now an option to view existing matrix. Using the arrow keys, select view existing array,

    Select the Inactive matrix. Select manage the Array.

    The only options available is to activate the table or delete the table. In order to get this controller to accept the disk configuration, select Activate array by using the arrow keys to highlight, and then press ENTER.

    Confirm Activation.

    Return to the main menu and select SAS topology and check that the two tables are active.

    Let me know how it goes.

  • The fastest way to update Equallogic firmware without RAID RAID array initialize?

    I wonder if anyone has something they can share on how to upgrade the firmware to a new device (or newly reset) without having to wait for the RAID to initialize completely?

    For example, I've reset a PS6100 I just booted and began to update the firmware, however when I get to restart phase it fails because the RAID is only 2% initialized.

    Yes, you can reset it.  It will be just destroy everything again.

    Re: CLI.  Yes, if you make the configuration of the serial CLI, it will allow you to delay the RAID strategy.

    You'll just need assing the ETH0: IP port, then group IP and group name / password.

    You will be at the GrpName > prompt.   Then you can transfer the kit firmware once again, run the update to install version 7.0.5.   When she comes back, you can either:

    GrpName > member select raid-policy

    If the disks are TB or superior SATA, you really want to do RAID5 if you consider that.   Have chosen RAID6 or RAID50.

  • Regular driver change RAID array

    I have a Dell Precision T5500 running Window 7. I want to get rid of the RAID group configuration, i.e. set up a RAID (drive) one pilot regular.  I would greatly appreciate any useful guide. Thank you.

    Hi Zqu99,

    I guess you have RAID 1 (mirroring). If so, then simply turn off RAID in the BIOS of Intel RAID (Ctrl-i) should work. I think the option is ' restore discs non-RAID '.

  • Migration from VMware to USB RAID array

    VMware runs from a USB, installed from VMware-ESXi-5.5.0-1331820-HP-5.72.27-Feb2014.iso.

    Datastore1 contains virtual machines.  Datastore3 contains a data reader to one of the virtual machines.  Datastore2 is not used.

    Can I install VMware for a current HP specific image to the partition currently containing Datastore2 without losing my VMs on 1 and 3 data warehouses?

    Thank you!

    Oh now I understand! Logical drives separate are separate as readers for ESXi (and any other OS). So if you take the right one for ESXi, the last two must remain intact.

    I did this once (two logical drives on raid-controller) simple installation and did not know what is happening, so I backed up all virtual machines off site. But only the logical drive that I picked up for ESXi installation has been re-partitioned.

    0b: 00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05)

    Subsystem: LSI Logic / Symbios Logic MegaRAID SAS 9266-8i

    It seems that there is no kernel driver is handeling my raid card. To find the results of the adapter in the following using megacli

    root@Gondolin:/# megacli - adpCount

    County controller: 0.

    Exit code: 0x00

    Of course, the map is not visible the system at all. Manually load the modprobe megaraid_sas driver doesn't change anything. Google did not bring much usfull information, only of discussions with dead ends. So I started to wonder if I did something wrong initially, or if I'm doing something which is supposed to be gives in a driffrent more apropriat way.

    Is there a better way to spend logacl storage in a virtual machine? Or should I continue trying to get the card works with the approach that I have chosen? Maybe switch distro (would not very fond of that)?

    I'm grateful for any help

    RAID: mentioned above

    I thought that this myself. After that I spent about two days on google. It became clear that the service I was looking for is "RDM" (and the following pages on the VMware Documentation). If local LUN is not officially supported for this function, we can make it work via the service console. This blogentry explains the process quite well. But be aware that this is not officially supported. Regarding performance issues, I found this.

    I was testing the rate r/w on the network I ran, just out of curiosity, quick test using dd:

    Read test:

    dd = root@Gondolin:/# / mnt/data/test if = / dev/zero bs = 32 k count = 65392

    65392 + 0 Datensatze ein

    65392 + 0 Datensatze aus

    Kopiert 2142765056 bytes (2.1 GB), 11.065 s, 194 MB/s

    Write the test

    root@Gondolin:/# dd = / dev/null if = / mnt/data/test bs = 32 k

    65392 + 0 Datensatze ein

    65392 + 0 Datensatze aus

    2142765056 byte (2.1 GB) kopiert, 10.1793 s, 211 MB/s

    I hope that this will help future users with the same issue.
