• How to map esx storage clariion lun number data store

  Hi all

  I'm at a client, and they say there is a plug-in to vSphere to show the amount of data to clariion lun mapping esx.

  Can any that confirm it, let me know where to find and how to install it?

  Thank you!

• LUN data stores

  Hello

  Im just reconfigure our SAN and have a wide range of installation as a single LUN to ESXi 4.1.

  I was under the impression that I could have warehouses of multiple data on a single logic unit number, with each host accessing a different data store on this LUN?

  Can Somoene confirm?

  Or will I have to cut the table side SAN and assign a piece for each data store that I want to, on a different LUN?

  Thanks in advance to all.

  normally it is 1 LUN = 1 data store, and several host can access the same data store, so that the virtual machine can be migrated to different host (vMotion).

• 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

  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.

• 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.

• A cluster of vCenter will share a single data store on a NAS?

  I have a vCenter 3 ESX host cluster. I want that these 3 hosts to share a single data store on a NAS (Dell Powervault md36xxi).

  
  

  The goal is that if one of the hosts go down, the other two still have access to the unique shared data store on the NAS.

  So far, I've been able to create a separate data store for each host on my NAS.

  Any help would be greatly appreciated. Thanks in advance.

  Since we normally have a 1:1 mapping between LUNS and data store, if the three hosts share the same LUN, then they will also share the data store even... just the map the LUN to all three hosts, using the vCenter create a store of data with vmfs format and three guests will share the data store. If after having create the data store on the hosts of the first, if other hosts do not see yet the store data, just try to rescan the host for new storage devices and data warehouses.

• Help adding extensions to a VMFS data store

  Hello people,

  I am working on some automation for creation of data store and must be able to add extensions to a data store.  The initial creation of data store works well enough at this point, but I'm a little puzzled about how to add additional extensions.  In my example, I am using the navi cli to make the LUN UID off the coast of the Bay of EMC, then format it correctly for the canonical name the host for the creation of data store.

  I read a little about the extendvmfsdatastore here , but I am not able to separate the part "add the measure" of "questioning the existing data store and remove references to pass."  If someone has an extract whose orders must be performed and the text to pass to the .extendvmfsdatastore method, I'd be very happy.  I know measure in several data stores fall into disgrace with VMware, but I can't migrate 10TB data storage immediately.

  Thanks in advance!

• get the data store with details of mapped cluster

  Hi with the script below, I am able to do data store maps on which the cluster and its host details... but I'm having multiple LUNS how to write for everyone to get to each store data below the output...

  Get-data store 'testdatastore ' | Get-VMHost | Name,@{N="cluster select '; E={$_| Get-Cluster}}, version

  Output:

  Version of cluster name

  10.0.0.0 testcluster 5.1.0

  Desired output:

  I need the name of output data store because I check for several data stores... can someone help me to get .csv exit foreach datastore as below

  Data name cluster version store

  testdatastore 10.0.0.0 testcluster 5.1.0

  testdatastore 1

  10.0.0.1 testcluster2 5.1.0

  What type of data store?

  I'm asking because there is no mentioned properties (. ExtensionData.Info.Vmfs.Extent) for data warehouses is of type NFS:

  PowerCLI C:\Windows\system32 > ((get-datastore_iscsi*).ExtensionData.Info.Vmfs.Extent). Diskname

  NAA.60a9800042594835695d453439742f53

  PowerCLI C:\Windows\system32 > ((get-datastore_NFS).ExtensionData.Info.Vmfs.Extent). Diskname

  So, you'll need probably something like this:

  Get-Datastore. % { $ds=$_; Get-VMHost - Datastore $ds | Select @{N = 'Data store name'; E = {$ds. Name}},@{N="NAA '; E = {if($ds.) Type - such as 'NFS') {'NFS'} elseif($ds.)

• 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?

• get support scsi LUNS for the data store?

  I've been delving into the different classes available to HostSystem.queryHostConnectionInfo () and none of the properties appear to contain the id of naa I see when I look at LUNS on an HBA.  How do you get to LUN support for a data store?

  Figured it out.  For anyone else who wants to know:

  I created two actions, one to return a hash of the id of naa-online data store object and another action to return a hash of the naa-online drive scsi id

  // actions
  //getDatastoresKeyedByLUN
  var o_diskHash = new Properties();
  
  for each (var scsiDisk in u_host.config.storageDevice.scsiLun)

  Is it possible to use autosize, as the data store long filenames trunctes.

  Try Autosize

  Get - VM (Get-content c:\temp\vms.txt). Select-Object - property @{Name = "VMName"; Expression = {$_.} Name}},VMHost,@{name='ClusterName'; Expression = {$_.} VMHost.Parent}}, @{"Name" = "Datastore"; expression = {($_.)} DatastoreIDList | %{(Get-View-nom de la propriété-Id $_).

• Removal of LUNS in a data store

  I installed a new volume of virtual disk of three 2 TB (RAID5) SAS drives on our HP SAN. So I have 4TB as the disk capacity that LUN. Now I was ignorant of the fact that the maximum size of a data store for ESXi 4.1 2 TB - 512 bytes. So when I added this new 4 TB LUN to a store of data on ESXi 4.1.0, only 1.64 TB has been appearing as available as against 4 TB or 3.64 to capacity. Now, I want to delete this new LUN of this data store and return to the utility of HP storage to recreate smaller i.e. two 2 TB LUN management. However, the problem I have is, I don't know how to remove this new LUN in the data store to which I added this without losing data or a data store. In my case, I had a data store 300 GB to 1.09 and I added this new 1.64 TB LUN to this Datastore.But I want to delete this LUN data store. Thank you, Clément

  I'm afraid there is no way taken in charge to remove a measure from a data store. If you want to use the entire disk space, you must destroy the entire data store.

• How to span multiple LUNS on one (or less) data store (s) in Vmware ESXi 4.1 vSphere environment?

  Hey guys -.

  I currently have 2 hosts ESXi (version 4.1u3), 1 vCenter Server and 1 EMC VNXe3300 SAN (20 to via iSCSI) that make my virtual environment.

  On the EMC is, you create VMware Datastores (which have a limit of 2 TB) then connect these data storage to VMware ESXi hosts.  Once logged in, would continue it the process through the Add Storage Wizard via VMware to connect the disk/LUN storage via iSCSI.  Ultimately, the Lun (s) would then be accessed through the virtual environment (in the Configuration > storage > data warehouses) as generally expected.

  Due to the limit of 2 TB (both on the CEM, Version of VMware and VMFS3) on data warehouses, I find myself with having several data warehouses being created on the side of the EMC and VMware (see photo) appearance.  I know that's not rectifiable via CEM level, but I was wondering if there was any way for me to bring together all these data stores on the side of things VMware.  This way rather than navigate to Configuration > storage > data warehouses and separate iSCSI indicator 6 data warehouses, it would just be a (or more, but less than the existing) data store; It would then extend in all actual data stores that I would.

  I don't know what the appropriate terminology is used to describe it, but I hope someone can help me to what I want to achieve.  Or at the very least, can you please steer me in the right direction.  If this isn't something that can be achieved or it is discouraged, what are the other options which would be recommended?

  Thanks for the help.
