• 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!

• Why the store of data/LUN locked automatically

  Some of the virtual machine are not accessible, and some are very slow, after investigating everything that it's a matter of SAN data store is locked so LUN Reset to cancel the lock to a SAN / LUN

  Problem is resolved after rest LUN.

  Now, I want to know why the locked automatically store data/LUN

  You can check if a host is isolated recently network - HA sometimes continually tries poweron VMs elsewhere and locks prevents it - other causes is a year very busy Bay SAN not finding time CPU to release locks... vmkernel hosts should help... Also look for VC events for the isolation of the host

• Cancellation of the assignment and reassign the data store by using different LUNS that datastore has not appeared.

  Hi all

  I have a data store after vdisk1 I have not assigned the vdisk to data store and reread the esxserver, the data store has disappeared.

  Again, I assigned the vdisk using the same number of logical unit as before and reread the esxserver, datastore appeared again return.

  But if I use a different assignment vdisk lun and on a new analysis of data store does not appear.

  Can someone tell me if the LUN must be even to see the store of data back again.

  If so why. ?

  Is there a vmware documentation to substantiate this claim.

  concerning

  Neela

  What do you mean by vdisk1?  The data store are stored as metadata on the LUN, when is formatted VMFS.  If you remove the LUN the VMFS is sitting on, then Yes, the data store will disappear.  If you only remove the vmdk who lives on this data store, then no, the data store must remain as it is, and you should be able to move the vmdk on the data store as needed.

• 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.

• Find the store of data with more free space.

  So I'm trying to build a script to configure the virtual machine.

  I'll have it retrieve the node to keep newly available vm out based on the cluster, I said to use. I'm just using the Random function to do that then I select a node in the cluster.

  Where I have questions, how can I

  find the data store less used, based on a particular data store naming scheme.

  I want to say is:

  Hypathetically, I for example named data warehouses:

  store data-prod-01 200 GB free

  store data-prod-02 500 GB free

  free data-prod-03 10 GB store

  free data-qa-01 200 GB store

  free data-qa-02 1000 GB store

  I want to throw in a piece of code to tell him to watch data warehouses "datastore-prod *" and place the virtual machine on the store of data with the most space. (that's assuming that the vm will agree on the DS and let fresh generals)

  I guess I want to know if it is possible?

  I would also be concerned about scenario that perhaps the vm should I build just will not match on any of my other data store. I guess I need a logic to check if it is still possible.

  This is more than a wish rather than a necessity. I'm thinking if I just read the info, or use a cvs file after running the script. Any recommendations would be greatly appreacted.

  Hello, drivera01-

  You should be able to do this with a very small amount of code.  Download all data warehouses that correspond to the model name, sort free space (in descending order) and select the top one.  As:

  ## get the datastore matching datastore-prod* that has the most freespace$oDatastoreWithMostFree = Get-Datastore datastore-prod* | Sort-Object -Property FreespaceGB -Descending:$true | Select-Object -First 1
  
  ## if the freespace plus a bit of buffer space is greater than the size needed for the new VMif (($oDatastoreWithMostFree.FreespaceGB + 20) -gt $intNewVMDiskSize) {<# do the provisioning to this datastore #>}else {"oh, no -- not enough freespace on datastore '$($oDatastoreWithMostFree.Name)' to provision new VM"}
  

  The second part, where it checks for sufficient freespace on the data store that has the most free, can be updated to behave as you need, but that should be the basis.  How does this look?

• Why there is no data type that stores only date (without the part of hour)

  Hi all
  
  Is there a particular reason to not have a data type that stores only date (without the time part) in ORACLE - I'm asking this because the DATE (without a time) is a type of data very frequently used in any application.
  
  Thank you.

  In fact, I was reading about the types of data...

  We have numbers with details. According to the argument above it is not necessary. We need only a default type NUMBER.

  It depends on. Much of the work that we do, we only create just like NUMBER and don't worry precision. However for financial purposes, a clarification for the monetary values of the application can be very important.

  In the same way do all the varchar2 (4000) character data type. Why we would require an option to specify the length... ?

  Because you can limit the size of the string that can be stored.

  I see what you're saying, but that's just the way it is. Why Oracle would need to confuse the issues by having several types of data to store the type Date and DateTime requiring an explicit or implicit conversion to be necessary, or provide an indicator of accuracy against the date where this indicator of precision would take of additional storage space on something that is already only 7 bytes.

  There will be internal historical reasons why it has happened this way... but really there is no need to worry.

• After doing a failover and failback - store of data replicated

  So I have a question of the State of the data store where my vms are in fact a table after failover and restore.

  I did a few VMs reocvery failover, and then made a reprotect and definitely failed virtual machines to their original location... Then when I discovered the virtual machines they are running on the original cluster before testing with SRM (as expected)

  what I didn't expect is the data store using the vms system has the prefix "follow" yet.

  I really don't think that the store of data they use is a snapshot, when I did an esxcfg-volume - l, nothing came as far as snapshots.

  So has she not only removed the prefix 'snap' or did I miss something...

  Thank you!!!

  Regarding your point about retrieved data warehouses, they actually aren't all that normal.  During the recovery process, vSphere resignatures LUN and it is this will need the LUN that makes vSphere treat it like a snapshot.  The prefix '-wink', says @memadd, is just the default agreement used by SRM for resigned handling LUN, that they are all in the recovery.  The recommended option to keep the original name works well, I've used it before datacenter migrations.

  These could help.

• Best way to migrate data from a store of data to a ROW

  Hi all

  I have a maybe simple question.

  I have some SQL clusters to customers that are not configured by the best practices of VMware.

  They are running ESX 4.0 with vCenter 5.0 u2 u2

  Some of them are running two nodes on the same ESX, some of them have mixtures of RDM and data warehouses and LUNS are connected by mixtures of policies of multiple paths.

  I can make changes to the MPP and the separation of the knots without problem, but I was wondering if anyone has recommendations for the data transfer of any store of data that exists in a ROW?

  Obviously if it is possible I would disconnect the data store, add as a RDM again but is it ok to do?

  Are there catches hidden here?

  If this possible isn´t would I need to create a new drive as a vMotion RDM and the storage of the data between the 2?

  I Don t need to migrate data for the operating system, the data on disks, so I can use storage vMotion for this or it would be better to run VMware converter?

  Someone at - it advice or recommendations?

  Thanks in advance

  Mark

  You can't add the data store to a server asa RDM because the data store is in VMFS format.

  you could use vmware converter or restore backups to place the data on the rdm.

• ESXi and store design data

  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

  .

  almost:

  ESXi 5.0 supports LUN/data warehouses with up to 64 TB (without extensions). = RDM in physical compatibility ((pass through)) mode

  AND

  2 TB less 512 bytes for virtual disks on VMFS datatores. = Of VMDK more RDM in virtual compatibility mode

• 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".
