Failed to create data store on LUN ISCSI

• Detach the corrupt empty VMFS datastore hosts (data store is an iSCSI LUN)

  Sorry people - can't all in fact it nails with a Google.

  I have a corrupted (size beyond 2 TB by accident) data store. Migrate all hosts out there - she is empty.

  As it is corrupt, it does not in the normal way.

  Now I CAN just tear out of the EqualLogic SAN - but I don't want to confuse ESXi.

  Can someone tell me how "friendly but firm" about ESXi to let go of it before I delete it the San?

  Thanks many many - Tim

  Like a little help, I have denied access of a host to the LUN and restarted mode maint.

  It is not in the view hosts of storage thereafter.

  If I repeat, it erases it completely from vCenter?

• Newly created data store only appear not

  I am building a new LUN NetApp that must be replicated on our site of Dr. I have create volume, LUN and configured the SnapMirror relationship. The SnapMirror runs successfully as expected. When I went to create the Group of Protection of RS, I had no options to select groups of any data store.

  I don't know there is something that I'm on. What should I do to get the data store to show as an option?

  We have a pretty standard setup.

  vSphere/Center 5.5

  5.8 SRM

  NetApp 8.2.3

  After further research, I noticed one of my hosts pointed out my LUN as "snap_xxxxxx" so I started to question the storage configuration. I built a new LUN, install the SnapMirror and SRM was happy.

• Can't see the logical volume when creating data store - vSphere 4.1

  Hi guys, got another problem with ESXi 4.1 on a HP Proliant ML350 G6.

  ESXi 4.1 update 1 has been installed successfully on the server on an internal USB. Our next step is to create a store of data through the vSphere client.

  The server has five 500 GB SAS configured in a RAID 5 array drives. The server has a HP Smart Array P410i RAID controller. I see five physical disks and logical volume of about 2.3 TB in RAID Utility. However, when access us the hypervisor via the vSphere client and try to create a data via a storage LUN/local store, the display shows then no logical volumes or the drive bays on which to create a data store.

  We are usnure why this is, as the ESXi 4.1 installation program could see this logical volume when I was installing the hypervisor, but he does not appear in vSphere for use in a data store.

  If anyone can help?

  Thank you very much.

  Each disk must be less than 2 TB - 512b

• What is a relationship between the data store and LUN?

  Hello

  I added 3 LUNS to a data store, but I can't list them since the MOB data store. Could someone tell me how to do it.

  Thanks in advance.

  LUNS was formatted as VMFS and created a data store? If not, it will not be displayed. You can search for available LUNS that can be used to create a VMFS with QueryAvailableDisksForVmfs volume

• Error in creating data store Local VMFS 2.3 TB RAID - 5

  Hi all

  I just reinstalled my ESXi 4.0u1, the local disk is configured as 6 x 500 GB SATA RAID - 5 altogether, it gives me 2.3 TB of disk capacity

  However, when I am about to create VMFS Local data store on the ESXi server it was fll of error as the following attached photos:

  can someone help me please in reconfiguring the VMFS 2 TB and 300 GB each?

  Thank you.

  Kind regards

  AWT

  Maximum size of the LUN is a little less than 2 TB.  Re-create the matrix, with two LUNS that is two 1.15 TB, both RAID-5.  Create a data store on the first, then add the second as a measure.

  Please give points for any helpful answer.

• "External I/O load detected on a data store" on LUN in vSphere Client version 4.1.0 build 345043

  Hello

  I have an ESX environment into a cluster of BL460G6 and 4 VMware ESXi, 4.1.0 installation 348481 in it.

  I have active DRS and the parameter ' level of automation of Migration: "="fully automated ".

  If I open the 'Home' = > 'Inventory' = > 'Warehouses', I have 26 MON, but only 9 in "mode healty", everyone has the following Alerts tab "alarms":

  Name:                                                                                    Description:

  Default alarm "Workload external I/O detected on a data store" which triggers if an external I/O workload is detected on a data store.

  Default alarm 'Use of data on the disk store' to monitor the use of disk data store.

  If I open "Alarm settings" on the "load external I/O detected on a data store" and choose the tab 'Triggers', the event carries the name according to 'vim.event.NonVIWorkloadDetectedOnDatastoreEvent', but I do not see what is coursing the alarm.

  What can I do to remove this alert? Is this a hardware issue on my LUN that generated this alert? (If Yes, what can I do about it?)

  Kind regards

  You must have an Enterprise license.

  Then check in the properties of the data store to see if the IGCS flag is set.

  For NOTTM there is a column in the list of data store where you can see if if on acceleration or not.

• Match each data store its Lun ID and the list of virtual machines in each data store

  Hello

  Can anyone help? I'm looking to create a report that will show each Monday name and store data to data warehouses, the list virtual machines belonging to the storage of data and the name of the VCenter at the top of the report. I tried several combinations but was more difficult to get the Monday. Any help appreciated gratefully.

  Thank you

  If you use only LUNS is an easy way to get the canonical name:

  Get-datastore. {Select-Object Name,@{Name="CanonicalName"; expression = {$_.extensiondata.info.vmfs.extent.diskname}}

  I don't understand your requirement regarding the name vCenter, but for everything else

  Get-datastore. foreach {($MyDatastore = $_)} | Get - vm | Select-Object @{Name="Datastore";expression={$MyDatastore}},@{Name="CanonicalName";expression={$MyDatastore.extensiondata.info.vmfs.extent.diskname}},Name

• issue of configuration for the store of data/LUN iSCSI

  Hi all!  I am all new to VMWare and iSCSI, and I have a question about data warehouses regarding being mounted on an iSCSI target.

  Here's my setup.  I have a Dell PowerEdge R810 connected over a link to 10 GB dedicated to a Dell PowerEdge 2950 that I use as a SAN.  The R810 has no hard drives in it, it starts ESXi on a redundant configuration of SD card integrated into the server.  My SAN software is Server 2008 Enterprise with Microsoft iSCSI software Target 3.3 installed.  I created target 1, LUN 0, 800 GB .vhd file sitting on a NTFS partition and set up a store of data on it in VCenter.  The data store is the size of the entire iSCSI, 800 GB target.  I have my first virtual server up and get 50GB of space between the data store.

  Here is my question: can I create several virtual machines using the data store I put in place?  I know it sounds like a stupid question, but my concern comes from some reading I did on several computers, access to a single LUN.  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  Issue of bonus points:

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  Thanks for your patience with a new guy.  I searched and read for hours, and I could have read too much so I thought that I had just askt experts.

  Hello and welcome to the forums.

  Can I create several virtual machines using the data store that I put in place?

  Yes.

  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  No, you should be fine.  One thing to keep in mind is that the Windows/MS iSCSI target is not a supported storage solution.  There could be problems of scalability with iSCSI Windows/MS, but you'll be fine in a VMware perspective.

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  You could, but I personally would put in place a different data store on another iSCSI target.

  Good luck!

• Nobody knows the largest available space supported for vmfs data store when creating a new form of vmfs data store a 3T lun mapped from FC storage.

  I traced a form of lun 3 t FC storage.

  And the project to create a vmfs on this lun, creating, data store, space available by default is 1024 G, no 3 t, so I guess that maybe some limitations.

  Anyone know? Thank you very much.

  Hello

  The limit is 2 TB - 512Bytes

  That 512 bytes is VERY important to remember.

  You will see that 1 TB as it roles once you exceed 2 tablespoons.

  As Anton suggested you can use two 1.5 TB LUN safely. However, you can in fact more than 500 GB LUNS or such. Will the LARGEST you can is not always the most efficient allocation of resources.

• vSphere ESXi 5.5: creating data warehouses

  I installed vSphere ESXi 5.5 on a system of self-build and downloaded VIClient her... everything connects very well.

  The system itself is an Intel Core i5 with 8 GB of ram and an Office CT pro Intel network card. Records are:

  • IBM 32 GB SSD (the ESXi OS is installed on this and can be seen fine... of course I guess).
  • a SATA III 1.5 TB drive
  • a disc of 2 TB SATA III

  The system can see the other readers, but when I try to create data stores that I can use, I get the error:

  Call 'HostStorageSystem.ComputeDiskPartitionInfo' to object 'storage system' on ESXi 'xxx.xxx.xxx.xxx' failed.

  Anyone has any idea why this would be and if I can do something? The only things I can think of existing partitions (it certainly is on the smaller disk as it was originally a server system 2008) or some kind of requirement for specific formatting, first.

  James

  This could be a problem with the current data on the disk. I suggest clean you the partition info using the DD explained to the KB VMware: Troubleshooting in the add storage Wizard error: cannot read this disk partition information to see if that solves the problem.

• size of the lowest data store then show storage

  Hello, I do not know why, when I add a new logical unit number data store to what I created in the storage appear at the VMware and then further down in storage.

  for example, I created a new LUN in the storage of 60 GB in size. but when I add a data store that LUN appears only 55.88 GB to 60 GB. where are the others? where are other 4.2 GB of my logic unit number. in storage, it appears with 60 GB.

  Why VMware view only 55, 88 GB 60 GB?

• Try to delete the data store: error DestroyVmfsDatastore

  Hi all

  I am trying to remove a data store (storage is iSCSI). There is no VM on the data store.

  In v2.5, I must click on remove datastore, she thinks for a few minutes and then remove the data of all servers store.

  In version 4.0, I clicked on delete, and it has only removed from a host. Instead of be connected to 8 hosts than before it was presented as connected to 7 guests.  (it should not be connected to all guests!).

  If I try to remove it from another host, I get an error message:

  "Error while configuring the host: DestroyVmfsDatastore: can't delete partition 1 on lun vmhba32:12:0 '.

  I tried this on two stores different data I needed to delete with identical results. Any ideas?

  Instead of be connected to 8 hosts than before it was presented as connected to 7 guests.

  Have you tried to force a rescan storage adapters?

• How many data store should be left to host his own execution

  Hi all

  I have EXSI 5.5 installed host recently. I'm going to create a new virtual machine on that host, but the data on this host store is about 2 TB and I want to put 1.8 to for my VM machine, so I only 0.2 TB left. The issue is with 0.2 left to there, that's enough to run its own code structures and data from the host? How to determine how much should be left? The same question for the memory and the processor.

  Could you please help with that?

  Thank you very much.

  Kind regards

  Thao

  ESXi is roughly Ligh weight. During Installation, the ESXi would automatically create the partitions. XXXX to hold (key code) bootbank, altbootbank, 4 Gigs vfat, store partition for tools and etc, that would be enough for the ESXi run and would not need anything else. A total of about 5 G of space is used and the rest should be left aside for you to create data stores to store virtual machines.

  From left to right on the space, ensure that you have left at least 20 to 30 GB per VM separately to run snapshots in your patch/maintenance cycles.

• Migration of virtual machines from a data store, and then delete the data store?

  Hello

  I have a future deployment this month and my Director wants to build a new RAID 6 array, create a store of data with the new table and then move all the VMS to the newly created data store.

  Then he asked me to take the old data store and remove it and the available space between the deleted data store and other stores of data in our shared environment. The question is when the new raid is created and vm has migrated to the new data store, which is the best way to remove the data store empty and make sure that the space available for other data stores? Any help would be appreciated...

  Greg ~.

  If all controls are met, you can go ahead and take it apart without any problem.

  I have re-iterate below checks:

  -No virtual machine is in the data store

  -The data store is not part of the cluster data store

  -The data store is not managed by the DRS storage

  -IGCS is disabled for this data store

  -The data store is not used for vSphere HA heartbeat.

  Especially highlighted 2 controls. Please note that SIOC can be enabled on the data without SDR photo store
