• Cannot create a store of data more than 1.37 to?

  Software initiator iSCSI in ESX sees the target 6 TB and when I go to create a new data store, it allows me to choose what size I want but after creation, it creates a data store 1.37 Tb in size. Have deleted and recreated many times, same blown away, the virtual disk and a bunch of disks on the san, a couple of times and recreated them still getting only datastore Tb 1.37.

  What I am doing wrong? Any help would be appreciated! It drives me crazy.

  See you soon,.

  ESXi has a limit of 2 TB LUN. It does not take account the piece of 2 TB of a LUN when they are larger than and uses only the rest.  You will need to split the storage in all LUNS (2 TB - 512 b) 3 or less.

• Error creating the store of data on iSCSI LUN (EMC CX4/120)

  I run an error when you try to create a data store on a Clariion CX4/120 system.  Connectivity to the San is performed via iSCSI.  I exhibited with success the target on the storage card and it shows in Configuration > storage adapters > vmhba33 > Details.  It has a capacity of 5.37 to.

  When I go to Configuration > storage and select Add..., I can select the disk/LUN.  The LUN appears here as well.  When I click Next, it fills the device information and location and also reported "the HDD is empty."  After 10 minutes, it generates the following error...

  Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" of object "ha-datastoresystem" on ESXi '172.20.100.78' failed.

  I did some research on Google and looked around here on the website of VMware, and I can't find any references to this error.  Are there log files for the process that I can look into?  I must engage EMC and see if there is a problem with the SAN itself?

  It has a capacity of 5.37 to.

  VMFS data storage limit is 2 TB less than 512 bytes. Try presenting small LUN, then it should work.

• Creating a store of data on ESX 3.5

  I have a setting wrong until a data store on ESX 3.5. Recently, I got a Dell PowerEdge 2900 (two Intel Xeon Quad Cores with 32 GB of RAM, just in case where this info would be important) and installed ESX Server 3.5 on it. Before installing ESX, I created two virtual disks on the server, one that was used to install ESX and VMs on and another larger virtual disk which should be used as the primary storage for virtual machines, images of .vmem more etc. The largest virtual disk consists of eight SAS 400 GB hard drives in a RAID 5 configuration. ESX is installed and runs on the first virtual disk very well. The problem I have is that when I try to add the virtual disk larger than a store of data in VMware Infrastructure Client it shows 2.54 TB capacity, which is what it should be, but is showing that 555,99 GB available space. This doesn't seem fair to me. This virtual disk has been defined, so it is completely empty. Maximum RAID 5 configuration must use the equivalent of one of the 8 disks for parity data, theoretically giving me ~ 2 TB of usable disk space to use as a data store. Is there something I'm missing here? Any help would be appreciated!

  Welcome to the forums - the problem is the size of the largest LUN - maximum ESX and ESXi recognized the LUN size is 2 TB by maximum configuration http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_config_max.pdf- so you'll have to sculpt your drive to the top in less than 2 TB LUN.

• Creating a store of data from local hard drive

  If I wanted to use the free space on the computer host ESXi as a data store, I need to partition the disk hard until I have install ESXi on it or I can do after?

  Default install ESXi uses your hard drive and converts it to a VMFS volume if you install it on local storage. If you plan to use the entire disk, just install ESXi with General settings you will have already created for you a data store.

• Create the store of data without formatting?

  I'm looking to be able to access physical drives on the host to the guest virtual machine. I'm under vsxi v5 and the virtual machine's windows server. vSphere client does not seem to allow he same disc for virtualmachines as VM Workstation configurations.  Is anyway to do this without creating warehouses of additional data for each hard drive and put in the form of each player. I'm looking to keep the data on the disks.

  There is no - its called has Raw Device Mapping and detailed here:

  Now, RDM are not supported on RAW SATA disks, so if you want to do this, you need to hack a bit, using this method:

• How to move a virtual machine to another store of data on the same host

  Hello

  I have a single ESX4 host with 3 data warehouses and I need to move a virtual machine to another data store, how can I do that since I don't have the ability to migrate the virtual machine when I am connected directly to the client with vSphere host and I do not have a server vCenter also?

  Thanks, Julien

  Hello

  Yes, you can use #vmkfstools-i /vmfs/volumes/datastore/VM/VM.vmdk /vmfs/volumes/datastore/VM1/VM1.vmdk

  For the record, the data store must be shared if you copy of VM and VM must be turned off. In the above command you copy VM.vmdk to VM1.vmdk and add the newly created with this existing VMDK VM.

• [ADF, JDev12.1.3] Which is the right place (for example, bean or AM) to create and store secret data that the user is unable to intercept?

  Hallo,

  in my page, when the user clicks on a button, I'have run an operation and in particular generate a code PIN and password that the user must not not know/interception.

  The STEM must be kept "secretly" in the comic book.

  I created a function to generate the PIN code in the 'Utils' to the ViewController project class.

  In the managed bean associated page I would deal with the click of the button through its ActionListener function.

  In this function I would also generate PIN call the "generatePIN" works and finally store the PIN in the comic book.

  Is the bean, the right to 'place' where build and store the PIN in the database?

  Maybe I'd better to generate the PIN and then store it throug a function of the module of the Application?

  Thank you

  Federico

  Well, he should go to the model because it is part of business process and is not part of the presentation of data.

  (AMImpl, VOImpl, or same ViewRowImpl are good places to write such code)

  The STEM must be kept "secretly" in the comic book.

  I don't know what that means exactly.

  Aspect of security, no matter where you place code (in the model or ViewController) because both are executed inside the Java virtual machine server-side.

  If you need to secure communications between WLS and DB, then open the database by using the SSL protocol connection (or create the stored procedure and generate PIN directly in db)...

• How to create a store of data with the small block size

  Hello

  I want to create a data store on two 160 GB drives. All the VI Client allows me to do is to create a data store of whole disc with 1 MB block. But for reasons of performance with the virtualized Oracle RAC, which is 8K organized, I want to go down to a smaller block size. But how?

  Is it possible to split my drive to (lets say) four parts, each with a smaller block size and putting them all together like extends in a data store? To create partitions with fdisk does not work, as the VI Client wants to use the unpartitioned disk. Any ideas?

  Robert

  Hello

  It is not possible. The smallest block size is 1 MB on a VMFS partition.

  Best regards

• How to ensure that "" is not creating a studio ODI data store. ?

  Hi Expertise,

  While I creates a store of DATA (TABLE) in the studio of the ODI, I have created a table name with quotes Double for the table as example 'TABLE_NAME'.

  Is there a method to get rid of this. ?
  At the studio of ODI, it does not show the name of the table with the quotes, but when I'm trying to see a TOAD, I get the quotes.

  Can someone help me on this. ?
  I can't do "' to the table I create in the studio of ODI.

  Thank you

  Hi Shakur,

  Go to the topology-> Oracle technology-> language (tab)-> delete quotes under object delimiter, and advance to the next field to ensure that the change is made, then save.

• ESXi and store design data

  Hi all -

  I find VMware site but can't find any info about my installation and hope someone can help me with a few questions about the configuration of the data store, or maybe someone has implemented a similar setup in their environment.  Any comments would certainly be appreciated

  
  Questions: I have two 5.0 ESXi host and will link to 5300 VNX via iSCSI. Each ESXi will host virtual machines about 6-Windows 2008 R2 File servers each - VMs C: 50 GB on iSCSI SAN disk. Data store single for example 500 GB for all readers of VMs C: create?
  In addition to the C: partition, each VM file server will host several partitions greater than 2 TB data, for example a 3 TB S: and T: 2 TB partition I create a store of data for each partition and under the VM iSCSI, select change settings, select Add hard drive, and then navigate to the data store for each VM partition? This means that I will create a data store for each partition of data correct?

  Thank you

• Cannot create a volume larger then Go 212

  Hello

  I created a volume of 12 to on equallogic storage and I'm trying to connect it with a bit of esxi servers.

  Once the storage adapter detects the volume it see all 12 s to.

  But when I try to create a store of data from this volume in vSphere I'm limited to 212GB and I can't create a larger volume.

  Any suggestions are welcome.

  Thank you

  Haris

  Hello and welcome to the forums.

  The maximum volume size is 2 TB - 512 bytes. It is documented in KB 3371739 - you will need to carve up this storage in an appropriate manner.

  Good luck!

• 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.

• 2.0 server loses the connection to the store of data on reboot

  I will install ESXi on my server in the very near future. I just ordered another NAS (Buffalo Terastation Pro 2 TB II) and prefer to use it for a data store since I can't afford a SAN skinning in LUN for my virtual machines.

  I'm running 2.0 on a Windows Server 2003 Server. I have a problem and I was wondering if you had this happen or know how to prevent it from happening.

  I copied some of my virtual machines from the current server to a 1 TB NAS (Netgear Ready NAS NV +) which is located on the network. I added the data store to the server pointing to it as a CIFS share. Everything seems to work fine until I restart the server... then it can not find the data store. I tried refreshing the data store, but it does not. I have to actually remove the data store and Add again... If I just try adding another store of data that it knows that it is mapped to the same location and she won't let me. So I remove, add a data store and computers virtual it appear in the server...  I thought I could try the drive mapping to the location of the data store but it won't let me just use the drive letter mapping, it requires the name of the folder too... Any thoughts?

  Thanx

  There is a workaround solution posted here:

  http://communities.VMware.com/message/1098864

  BTW. I found it by searching the community for "CIFS".
