After a failed raid array recovery my data store is missing

• Names of recovery SRM data store

  I just did a full restore on some demo servers and data warehouses on the side of recovery mounted with snap-< number > - DatastoreName...  Is this normal?

  Yes this is normal - ESX on any volume resigned proceeds to indicate that it was a copy and has a new signature. See the thread next to the advanced option to change it.

• Replacement of a data store - migration of virtual machines

  We have a VMware ESXi 4.0 installed on a SD card and our data store is on a dedicated internal RAID array. Our data store is running out of space... what we would do is remove the old hard drives and add new - therefore, delete and re-create the matrix RAID and the data store.

  What is the best way to migrate our existing data store / VMs from the old array to a new one using vSphere or vSphere CLI? How we then re - associate VMs on the SD card with the new data store? Advice would be appreciated. Thank you very much.

  Hello

  Looks like it's a single ESXi host.

  You will need to copy/save all the contents of the data store existing to another location (external HARD drive) while all virtual machines are closed.

  Once it's done and you are sure that the copied data are intact, you can:

  -remove all virtual machines of the inventory

  -remove the data store

  -Stop the host

  -replace the HARD drive with the new

  -Launch the host and to reconfigure the new raid

  -Create the new data store in ESXi

  Copy/restore all data to the new data store

  -Browse the data store and add all the virtual machines to the inventory (create a list to make sure you get all the)

  -Start the virtual machines

  May be a good time to do an upgrade of ESXi5 as well

  Please allow points to useful/correct answers

• Pouvez ESXi 4.0 to randomly delete all in a data store?

  I'll put up a test server ESXi. I had several virtual machines installed, he tested for a few months and was almost ready to put it into production. I installed it on a flashdrive of ESXi and had implemented our Synology DS209 RAID 1 NAS NFS data store.

  Yesterday, I installed a program on one of the XP virtual machine when all frose upward and I couldn't do a thing. I waited for a minute or two and finally tried to reset the virtual machine. This also seemed to have no effect, but after 2-3 minutes the bar to reset the vm started to go. Reset frose seized finnished for even 5-6 minutes before it finnally says "waiting for host" or something to that effect. I tried to log in Vsphere client to check what was going on, but received a message the host took time to answer. I tried several times but got the same message. I finally did a hard reset of the host as a last resort.

  When the host came, I was able to connect to Vsphere, but my datastore was gone! When I created the NFS datastore folder on the NAS, all my iso and VM have disappeared as well! It was not a file in this folder was left on the NAS. All other files on the NAS from network backup were fine and all files were there. I tried hard to recover the files, but do not have mangaged yet. The biggest problem is cannot determine the cause of the problem. How can I determine if there was a problem with NAS, glitch in VMware, a kind of Hacker/virus or something else? More importantly, how can I stop to happen?

  There is nothing in ESXi who would, on its own, remove all. If this is going to be a HOST I would not rely on a low end device as my store of data storage in an autonomous way. Add local drives and use the Synology DS209 for backup storage.

  Have you looked through records of storage from another source. You can often use several protocols to access the same directories. Try allowing CIFS on the same directory and try to access it from a Windows machine.

• Capacity of data store poster now much smaller than the original configuration

  Hi all

  I have my new configuration of server DELL R710 - 2 x 146 GB drives in the server on a RAID 1, connected to an MD1000 with 10x146GB in a RAID 10 SAS drives, and 5 x 750 GB SAS drives in a RAID 5.  My controllers RAID show each virtual table as you would expect to see the ability, however, VMware now shows my RAID 5 744 GB data store, instead of the 2.5 to he showed last night!  My VM on this data store seems solid, but I have no idea where my ability went.   I'm under ESXi 4 - free Version.

  What can I do to recover this loss of capacity?

  ESX (i) has a limit of 2 TB LUN and with ESXi you end up with the rest of storage after have been subtracted portions of 2 TB (i.e. TB 4.7 LUN donnerait.7 TB of storage (4: 7 - 2.0 - 2.0)).  With most of the controllers, you can create multiple LUNS on the same disks that you can use the complete storage if you create 2-Bay RAID 5 on the 750 GB drives.

• Configuration of San - data store have more than 1 LUN

  Hello

  We look at our San configuration for improvements. Our San has about 10 TB total.

  We currently have 6 LUN 1.5 TB all which are enclosed in 1 store 10 TB data

  It was suggested that we should NOT combine multiple LUNS in a data store for the reason if 1 LUN goes wrong then the entire data store is non-refundable.

  Although our SAN LUNS are created on top of raid 6 and are therefore a bit 'protected' by councils LUN 1 data store is interesting

  Does anyone have ideas to share?

  Thank you

  Tom D

  I would say that having a single data store, regardless of the underlying storage architecture is probably not a good idea.  Although this configuration is authorized you can paint yourself in a corner fairly quickly.

  1. one wonders about the maximum number of VMDK you should have by the data store.  http://communities.VMware.com/message/944120  Basically the more s VMDK on the SCSI data store more blocking of activity taking place on the disk, causing performance problems.  Each VMware engineer, I've talked about seems to stay around the VMDK 20 a range of data store, but that could change with vSphere.

  2 - How this data store backup and how long does it take?  What happens during a restore scenario?  10 TB is plenty of space and could take some time for the backup.  If you push it on tape and you must always restore the together 10 to it could take weeks or months.  This space by breaking into warehouses of smaller data gives you smaller segments of data that you can restore in case of disaster.

  3 - the number of data warehouses you have is very important if you are always looking to implement the Site Recovery Manager.  SRM relies on your storage device to replicate data between the sites.  There could be serious consequences on the rate of change of the data for a single LUN 10TB.  If you are moving in several data stores that it will make it easier to handle your recovery plan.

  Apart from the considerations above of VMware. I guess 7 performance LUNS in RAID-6 is not so great.  You have a lot of protection, but you pay for it with capacity and performance.  If you went to 10 stores of data and the LUN 10 you can change RAID settings at each data store to optimize performance, protection, and capacity.  For example 4 LUN RAID-10 high performance DB apps and 6 LUNS to RAID-5 for the ability.  With smaller LUN and data warehouses a disk or LUN failure will affect only a smaller set of services rather than your entire data center.

  In short, unless there is a really compelling reason to go with a single store of 10 TB database, I recommend you to change your architecture.

• 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.

• Data store / latency issues with HP ProLiant DL380 G7 - controller HP Smart Array P410i after disk 2014.09.0 SPP / hpsa - 5.0.0.74 update

  Hello

  We are currently investigating massive data store and the problems of latency of disk (mainly READING) on some of our HP ProLiant DL380 G7 with P410i (BBWC) controller.

  It all started after our half of regularly updated cycle for ESXi 5.1 U2 to:

  ESXi510-201407001 (no problem)

  -hp - esxi5.0uX - bundle - 2.1.1 - 2 (no problem)

  -HP-HPUtil-esxi5.0-bundle-2.1-15 (no problem)

  -hpsa - 5.0.0.74 (pilot) & SPP2014.09.0 (-assigned problems)

  It is not a permanent increase in the latency of reading, but rather meeting points that trigger alerts of Veeam. Store of data read latency increases about 5 MS to 100 ms as soon as this happens, but after a few seconds, everything is back to normal. These data warehouses special are RAID5 (but we have also seen some alerts on RAID1), having read and write cache enabled and the most affected machines are those with the LOWEST its use.

  We have a few WinServer2012R2 RDP for a small number of sessions (less than 5) - there is no noticeable delay on work on these.

  Maybe someone of you knows a similar behavior after you apply the updates of HP ProLiant servers. We don't have any idea on what to try next, a SPP restoration is not possible, maybe the pilot, but we find the correct predecessor, as the old drivers of 2014 HPSA leads the Group on the host computer.

  Best regards

  HZ

  Hello

  most likely, you have already solved the problem... I did some research and was in contact with HP. It is a problem with the driver hpsa - 5.0.0.74. It occasionally crashes when used with P410i. In the papers, you can find "WARNING: LinScsi: SCSILinuxAbortCommands:1843: failure, pilot hpsa to vmhba0. HP knows talking and working on the new driver. As a workaround, you can use hpsa - 5.5.0.60 (at least it works well for us).

• 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.

• Comment fails to power after moving to a new data store.

  I had this problem a lot where migrate machines. I navigate to the data store appropriate and right click on the folder of the guest, and I select "move". I choose the new data store and sit back and watch the progress bar. Once its migration adds the guest to the inventory and try to power on. Sometimes it works, sometimes I have to repeat the steps above twice. Why missing files when trying to turn on when I move the files this way?

  Right-click on the virtual machine, click on migrate.  Follow the prompts for destination until you reach the Select data store.  Click the radio button "Move virtual machine and virtual disks configuration files" and select the new data store.

• W700ds: Select RAID using recovery media created

  Hello!

  I am owner of a ThinkPad W700ds, but I guess my question will be answered there as well if it were a W700... Please, any help would be great!

  I bought a "used" W700ds with Windows Vista Business (COST and recovery partition intact, but no media provided). The laptop has been published with RAID0, but I was always doubtful that it has been implemented correctly. I spent some time he investigation this afternoon and noticed that the BIOS has not been configured correctly - it was set to AHCI instead of the RAID.

  I did the following:

  (1) created using the installation in the ThinkVantage software recovery media.
  (2) RAID enabled in the BIOS
  (3) entered in the RAID (Ctrl + I) starting at the top. I configured as RAID0 readers.
  (4) reinstalled Windows Vista using the recovery media created in (1) above.

  After completing the installation of Windows Vista would be failed to start - always BSOD'ing.

  I repeated step 3 & 4 above, select RAID1 instead. Exactly the same problem.

  I have since return to the setting of the AHCI BIOS and reinstalled Windows Vista using the recovery media and I'm back where I started (Windows installed, but in a RAID array).

  I did some research and it seems that in the RAID drivers are not included in the recovery media and this is the reason for the BSOD. I've included some of the many websites I read, both for your reading and, somehow, to check that I really spent some time to the consideration of this issue before asking for help.

  Media recovery that I created, that's all I have - is there a 'stand-alone' for me way to activate RAID? I prefer RAID1 (I would favour redundancy over the speed), but would be happy with RAID0 if this is not possible. It seems it is scandalous that Lenovo (aware - and obviously not "expected" as alternative installation media is considered a book 'around') offer the possibility to create recovery media, which does not have to reinstall Windows by using a configuration valid.

  It seems that it is not possible to maintain the RAID by Lenovo R & R, which probably explains why the seller announced the ThinkPad RAID, but it did not come to me as such (the seller has used the recovery partition to restore laptop to factory for me state before ending our sale - makes sense!). It seems a shame to have a laptop that offers RAID functionality and has the necessary equipment (RAID controller and two disks) and hit a sort of brick on software restrictions. Can someone advice how can I proceed to reinstall Windows with the disks in a RAID array, as I have only the Lenovo recovery media?

  Lenovo support are closed today due to the day Bank holiday UK but I'll try next time - but I'm afraid my fate is in your hands already, like the ThinkPad is out of warranty.

  Thank you!!

• Windows cannot load after a failed update

  Hello

  Last night, I had some windows update. After clicking on the button closure (option 'install updates and shut down' was) logging Windows appeared with a message "Configuring Windows updates 13 1 do not plug off your system" (something like that) but the update was stuck on the 6th floor for several hours and nothing was not happening... .not yet restart, so the frustration, I plugged my PC directly. Next morning, when I restarted my pc... windows could not load, and a text screen with a message similar to this "Windows failed to load. "a recent change hardware or software update could caused this" then give the steps to insert the windows installation disc and restart to repair windows.
  Also, I was unable to restart my pc in any type of safe mode and last known configuration windows proper.
  I have my windows since abt 1 year 2-3 months. and I can't find my Windows Setup disk...
  Can I use any other windows installation disc to repair my windows.
  or please suggest me a way to recover the data store in my pc... all my important information are saved in my pc...
  Help, please.
  Thank you

  Hello Rajiv111,

  It is perfectly acceptable to borrow a CD of Windows Vista to perform operations of repair with friends.

  You will not be able to upgrade a "on-site" due to differentiation of service pack.  However, you have several options to fix when you use the CD:

• Pavilion d4999t-2 double Raid disk recovery files

  Hello

  How did you come to the conclusion that your motherboard is toast?

  If you disconnect the SATA drive connectors hard and any other external device except a keyboard and video output and then it turns on, what is she doing?

  You must have a motherboard that was identical in all respects to recover a RAID set or pass (as you now now) crazy amounts of $$. Even with an identical motherboard (storage controller identical Intel and chipset) the RAID set may not be recoverable. You can not move readers to another motherboard and wait for everything to be good again. RAID is a special case and it simply does not work out like that.  If the RAID set has been the RAID 0 then the data are spread over two discs. This means no redundancy. When a drive goes down your data has disappeared. If the drive was RAID 1, then replace the failed disk can be done. The RAID set can be re-created by the Intel Matrix storage software solution.

  Here is a Wikipedia article that has a reasonable explanation of the many types of RAID and their advantages and disadvantages.  The acronym RAID means redundant inexpensive disk array. Redundancy in Information technology is the "repetition of critical elements" or functions of a system with the intent to increase the reliability of the system, usually in the case of a backup or fail-safe.

• ESXi 4.1 with 2.7 to RAID server only has a 750 GB data store

  I have a server ESXi 4.1 Build 260247. It has a controller Adaptec 5805Z with 2.7 TB RAID6 material. The ESXi is installed and running on a USB key. The server runs a lot and don't have any problem with the performance, but what I failed to note (after the creation and configuration of the 7 servers for an Exchange 2010 lab) is that the datatstore1 is only 740,75 GB. I looked everywhere in vSphere and online on how to access the rest of this storage. Under configuration > hardware > storage it shows the 'Adaptec disk Local (mpx.vmhba2:C0:T0:L0)", type = parallel SCSI disk to Transport, 2.73 Capasity TB.

  How can I access the additional storage on the disk? I certainly don't want to have to reinstall the LAB if I have to. Attempts to increase its size in the properties of the data store has failed. No error, that he just does nothing nothing found...

  

  

  Creating logical volumes on the RAID is a feature or function of the RAID controller, respectively the RAID controller software. Most RAID controllers authorize splitting of the RAID (unless it's a RAID level 0 x) in several logical volumes. You will need to check this for your RAID controller.

  You should probably migrate VMS off the coast of the current data of 750Go store and delete data store. Then, remove the current volume of 2.75 to logical and create a new logical volumes - maximum 2 TB - 512 bytes by using the controller BIOS or software RAID.
