Increase the store of data in gray

• 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?

• PowerCLI - there cmdlets to browse the store of data for files/directories and their creation?

  Hello

  PowerCLI - there cmdlets to browse the store of data for files/directories and their creation?

  If Yes, can you please let me know.

  I took a glance at the reference of the cmdlet, but can not find...

  
  Kind regards

  You can use the data store provider.

  It is documented in the vSphere PowerCLI Administration Guide that was installed with PowerCLI.

• Space in the store of data not released when a virtual machine is removed

  Hey all,.

  I have a game fairly simple up - two servers ESXi 2 Terminal servers. I'll have a problem, but with space in the store of data not be released on one of them after that I got a clone to the virtual machine, made my changes and removed the original. I can find no record anywhere, using vSphere (not in the inventory or when I browse the data store), but the HARD drive space using the server is still assigned somewhere.

  Any body have tips on where to find or how to fix this if it is indeed a problem?

  Any help is greatly appreciated.

  Thank you.

• We can dynamicaly fill the store parameter data in OEDQ?

  Is there a way where we can dynamically fill in the parameters of data store that varies from env to env to OEDQ, in reading common file of param.

  This will avoid the hassle of conflict and maintenance for all future password or port changes.

  
  

  
  

  Kind regards

  Yes, you can do so by Instant exteriorization and exports, because these are executable tasks that use the data store settings. You can then replace the settings stored with the real settings needed to run using command line parameters or run profiles.

• At what level is the store of data latency measured?

  Hello

  I have a question about latency of data store. I see that, generally, 20 to 30 ms latency limit before having the performance issue, but at what level is this limit? It is the seat of the latency of the VM? See vsphere?...

  In Vcops, when I select a data store and access operation - details see read/write latency: see comments AVG or device AVG? (see image below)

  

  When I select a VM in Vcops to see the latency time "of virtual machine", what is the difference between latency vDisk and the VM latency data store?

  

  I know there are a lot of questions in one thread, thank you in advance to those who take the time to answer.

  As esxtop counters, you have different counters to measure different parts of the stack. If you have latency at a disk level your queues will be filled and reflected. Latency of disk order is good enough to pick up underlying storage latency, but it depends what resource you are watching. The attributes derived from 'latency' exist here and there which are calculated based on the type of storage/etc to simplify your life and give you one place to search.

  When you start to look at the latency of the queue, you must keep in mind that focuses only on the queue. Take a look at the Duncan article (ESXTOP - bricks yellow) on it and your questions will probably be kept clear with regard to what are the bits/s and for the disk counters.

• 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!

• Expansion of the store of data RAID 5

  Hi, I have a store of data on disks RAID 5 4 and I want to add more than 2 drives in RAID 5, is it possible to add the data store / RAID 5 arrary keeping the data store existing / (VMs) data intact?

  Thanks in advance!

  You must enter your PERC BIOS.

  Follow the manual of Dell.

  And (like writing above), perform a full backup before you start.

• 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".

• increase the size of data (do) in the report

  Hi all
  Not a programmer, but plays with express request and try to learn on the go.
  In an interactive report that gets data from our database via SQL. I can change the areas of labels to make them larger and different sizes and colors with: Span command: span style = "color: red" and p style = "" are-size: 15px ' "
  < span style = "color: red" >
  < style p = "do-size: 15px" >
  etc... and change the size to, however, the actual data in the report seem to be a font of text.
  Most of you will laugh at me, but I already spent several days trying to change this without success. I would like to increase the size of the data for a column in the report so that column brings more notice in the report than others.
  
  I learn SQL on the move and am not very good at this and trying to find a good source to pick it up.
  Even in the examples of applications: I do not see where the data is in a format of larger text?
  I'm kind of embarrassed to ask this question, but I waste a LOT of my time trying to improve at least this issue a report until I try more complex questions.
  Any input would be greatly appreciated.

• How to increase the speed of data acquisition?

  Hey, currently I using 6210 OR of data acquisition and control switch. I used labview to periodically check the 7 switches and read data from 7 channels in the meantime (1 sample on request). I ran 70 loops for 10 groups of data, the cost of the time looked like 2.2 seconds.

  I would like to end a 700 loops in 2 seconds, is it possible to improve?

  Thank you

  PEM

  Look at the Terminal stop of the DAQ Assistant Express VI. You are starting and stopping of the task for the acquisition of data on each iteration of the loop.

  Starting from the help file:

  Stop

  Specifies to stop the task and release device resources when this Express VI ends execution. For ongoing tasks, this entry is FALSE by default, which means that the task is running until the application terminates. To stop the task, you can use the device again in the same application, wire control wire you the Conditional stop this entry to the same terminal of the while loop. For single-point and finished tasks, this entry is TRUE by default, which means work stoppages after all samples are acquired. To optimize the performance of single point when using this Express VI into a loop, wire control wire you the Conditional stop this entry to the same terminal of the while loop.

  Also from the help file:

  Continuous single point of entry or exit, the of VI Express DAQ Assistant cannot allow optimal operation. See Acq & chart voltage-Single Point optimization VI in examples\DAQmx\Analog In\Measure Voltage.llb for an example of techniques to create more powerful applications, single point of I/O.

• May not increase the value of data chart history but may decrease

  Hello

  In my application, I use 3 cards. I have 250 Hz sampling frequency on my system and I want to display a different number of seconds on my paintings.

  By default, the chart history data have 1024 points, which is second ~4.1.

  Now the problem is, if I put this value Let's say 100, it works well, is less points on the graph.

  But, If I try to back to 1024 or any value that is greater than the previous, it won't affect my chart.

  Graph will always display the lowest number of points of each value written in 'length of the graphic history ".

  Is in fact the value in the length graphic window, but it does not really affect.

  In addition, the problem is that it worked fine yesterday, but today it stopped working.

  I also have a VISA for VCP USB port, if this has something to do here, but I'm sure that's not.

  Thanks for the help and answers.

  Make sure your x-axis are the autoscale value.

• Increase the capacity of data store, which with the block size?

  Hello

  I am trying to expand my datastore 2 TB, I added a new lun 2 TB of the FC SAN TB 4 even and there is no problem adding this in the existing data store.

  But the existing data store is formatted in VMFS3 with a block size of 4 MB for a maximum file size of 512 GB. But when I try to extend the data store to select the size of the block is set to 1 MB and disabled.
  The measure automatically takes on the size of the original block or wil he get a block size of 1 MB? There are some > 256GB files on the existing data store and I think I'd get a strange behavior, if half of the data store is 4 MB and the other half is 1 MB blocksize.

  Can anyone confirm that the blocksize wil be the same for the measure?

  I can also make a second warehouse 2 TB one manually fracture the virtual machine on 2 data warehouses. is there any advantages or disadvantages to this approach?

  Don't you worry, add an item to an existing data store certainly will not change the size of the block. In any case, if it is an option that you can use two data warehouses, I would. With two distinct data warehouses that you will not only be able to spread the load on each of these LUNS but also avoid the complexity. With ESXi 5 (VMFS-5), a single LUN can grow up to 64 ~ to without needing extensions.

  BTW, a 4MB block size allows 1 TB less than 512 bytes.

• ODI 12 - problem with missing data in the store column data types

  Hello world

  We have recently installed Studio 12 on Oracle RDBMS ODI. We have created some topologies, contexts and the logical architecture. We have created the necessary templates and made reverse engineering. The strange thing is when a model data store opening, we have noticed, the data types of its attributes are not displayed and cannot be selected in the drop-down list because they do not exist yet. You can see the image below.

  

  So the mappings are not correctly executed because on the stage of the creation of work tables CREATE script was not generated correctly. (It's something like "CREATE TABLE < name > ()")

  Anyone can give an idea what could be the reason for this and how might be solved?

  Any ideas would be appreciated.

  Thank you in advance.

• 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
