Ability to store data about the free space is not the same in VMware and 3PAR

Hello

I'm running vSphere version 5.1.0 Server build 799731 and all my ESXi hosts running the same version: 5.1.0 799733.

I use 3PAR as a storage system for my VMware environment, but on some of my LUN created, I get a different number on what is currently available as a free space on the LUN.

On a LUN (LUN2_R5), vmware says that is has a capacity of 3 to and free pace on TB 2.08 (and it has been updated this morning).

But if I look in my view of 3PAR system, the same number of unit logic (LUN2_R5) has a size of 3 TB, but the size of the user used in 85% (2.6 TB of data).

If I do a look of VMware in the LUN, corresponds to the size on the LUN with the VMware view server, but I do not understand why 3PAR has another number.

Can you help me?

Kind regards

Your storage system only "knows" what's on the VMFS file system. As soon as the space is allocated, it is marked as used from the point of view to the storage.

  • several stores data on the same disks

    It's so strange. I can't create several stores data on the same drive. I have a 2 TB plugged on my server (motherboard) disk and after that I created my first store of data (100 GB), when I return to create another, that the drive isn't an option for me to create a new data store of. When I delete the data store, the drive comes as an option to create a new data store of. WTF?

    of http://pubs.vmware.com/vsphere-esx-4-1/wwhelp/wwhimpl/js/html/wwhelp.htm#href=fc_san_config/c_making_lun_decisions.html

    A logic unit number must contain only a single VMFS data store.

    I guess the reason for this is a SCSI reservation. Even if this has been significantly reduced in 4.x it is still necessary for some operations. Each SCSI reservation - even if this is necessary for an operation on a datastore - locks the entire disk and could therefore cause problems on other stores of data on the same drive.

  • Data store space used not maching between VMWare and 3PAR

    Hello world

    I have a strange behavior between our environment VMWare and 3PAR storage system.

    I checked each data store of our cluster and for each of them, the space used in vSphere Client does not match the size of the user 'used' their volume associated with 3PAR.  The value displayed in VMware is higher.

    For example, our data store named DS03 has space around 1 TB in VMWare.  And when I checked in the Console of 3PAR, I see that the volume created for this data store has a size of the user 'used' 722 GB.

    While doing some research, I came across this post: ability to store data about the free space is not the same thing in VMware and 3PAR

    But the problem I encounter is quiet different. It's the opposite. I do not understand why the displayed value is higher in VMWare...  We are also running vSphere Server version 5.1.0

    Any advice? Ideas?

    Thank you very much.

    It's the ASIC 3PAR inline zero detection function stripping zeros of incoming data until they land on the disc. Www.3parug.com try this happens a lot.

  • Need to consolidate 2 vmdk in 1 store data on the SAN.

    Hello

    I have a situation where I created a server (Windows 2008) with 2 drives and E. C resides in its own store of SAN (80 GB) data. E is an another data store (also on the same SAN), 500 GB. ESXi/vCenter 4.0.x

    Unfortunately, the instant/VM SAN backup software will not support a VM with several data stores (I know, stupid is not it?). Data recovery product VMWare supports this, but anyway...

    If I elect not to reconfigure this virtual machine by using a single SAN data store to accommodate two C & E readers, I was wondering the best way to do this? I have vCenter (essentials more, so no Storage vMotion or something fancy).

    I note that the navigation data store I see vmdk files can be a right click and there is an option "move to".  My 80 GB data store contains all the vmx files, etc.

    So, I thought I could:

    1 resize the 80 GB to 580 GB or slightly larger SAN volume.

    2. extend the vmfs from 80 GB to 580 GB data store. I expanded vmfs in the past, it seemed pretty good. Did not notice the extents, are problems that say.

    3. move the vmdk to 500 GB in the new size 580 GB data store. Only, he has about 60 GB of data and is thin provisioned in VMWare and SAN.

    4. make sure that the VM settings show the correct location again for his inappropriate disc.

    5. turn power on and test.

    Or well, maybe I thought I could create a whole new data store of appropriate size to keep both drives, then run the converter to clone the virtual machine on the same host, but with records changed to go into the same data store (new).

    In the meantime, I asked Equallogic to explain why their product can't make backups of virtual machines with multiple data stores. This will be more important for an Exchange 2010 deployment later this fall... I intend to have 2-3 LUN used for databases, newspapers, bones.

    I would NEVER do a store of data of the exact size of the VMDK files that are contained in this... You must have at least 10% free space (or do not exceed 90% of use on the data store). It's a good idea, even when using a provisioning, because if your VM to start using their allocated space (when you are too far on allocated) you will quickly encounter issues.

    I would like to make a single 1 TB LUN, migrating the virtual machine (and all it's files) to the new data store and go from there. I would advise to check the VMDK file names since you could easily have the same exact since filename you places on two data stores differetn VMFS initially (another good reason to not do NOT)... I did it a common practice to make sure that a VM resides on a single store of data/LUN at a time. Go with this method ensures that all software/tools/utilities will not have a problem with the virtual machine (or all VM)...

  • R12: Copy a group of companies with configurations, metadata and data in the same instance of OA

    The idea was born to a very common condition between the companies IT. pre-sales and pro-ventes groups do various tasks, including the response of the RPF/RFI, PoC, building, Solution architecture, customer demo etc. Ususally they do not have the dedicated application instances, or rather they do not find a sufficient number of cases of applications dedicated to deep study of the road. Every other day a group cries out for an Apps instance and the same gets lift for senior management in short time. It gives a lot of pain to the infrastructure/DBA groups because they fail to meet people like them, due to the limited availability of free nodes, resources, networks and space etc.

    I have a Vision of the R12.1.3 (tell SID = VIS1213) installed on a Linux machine. The box is quite busy with his hearts limited, showing little free memory and the attached SAN has insufficient free space remaining. A group of Oracle Apps pre-sales consultants, says "Group 1", is the use of this.»

    Now the 3 other groups are asking for a R12.1.3 Vision instance separately for different reasons below. Each of them wants the instance again and do not share with others.

    Group 2 for deep study of the road against a critical response to RFP
    Group-3 for the development of a point of contact for a customer demo
    Group 4 for the manufacture of PUK media on some business processes

    In this scenario, I should install 3 distinct Vision of R12.1.3 (using CDs or downloaded zip) or clone VIS1213 in 3 different places with different SIDS, possibly on one or more separated nodes (as above Linux node has insufficient free resources). In this case, the need for available server resources and disk space multiplied by 3, so that DBA maintenance for these 3 new instances is added.

    Hope that I have clear air up to this point.

    Then I was thinking if we have "virtual instances" within an existing instance of Apps, by copying from a vertain org level. First I thought I'd take THE level, but it will not work if an instance of group to work with HRMS claims. We must therefore take business group level. After that we will create the appropriate role and responsibility, user profile options so that the new user can see and work on the new BG and data area down only. It will be like a separate instance to use.
    Benefits of my desired task will be

    -no separate server resource, the required network
    -no additional DBA not involved maintenance
    -no separate required backup plan

    So here it is to create 3 new "virtual instances" right within the same instance of VIS1213. New groups will have same URL, same existing TNS details but 3 credentials different existing access. Each of them would be limited in a way so that they can not see each and other data and can not hurt each and other changes.

    This can be achieved if we can copy an existing group of its activities with org structures, metadata and data, within the same instance. Oralce planning cannot be copied within the same instance configurations.

    What I've done so far was I manually created a new BG, attached an existing sobbing (CoA, Agenda / currency), created a new, copied and modified accounting structure flexfields before fixing, created the new ORGANIZATIONAL unit, and then a new InvOrg of master and a new InvOrg clild, defined the profile MO some GL and HR profiles. Then I extracted finished master and data assignment article category Masters against a master/child existing InvOrg, updated the data for newly created InvOrgs, inserted into tables insterface and ran seeded import conc program element. Except for a few, all data have been loaded into base against new InvOrgs tables.

    Then I tried with master provider (with sites and contacts). A few AP configurations are required, and then data provider (+ contact + site) have been loaded against OR newly created (under new BG) base tables.

    I do not proceed after that. I'm currently looking for ideas from the experts on how to go further.

    Planning is able to create this kind of 'virtual instance' within the same instance of OSTEOARTHRITIS?

  • How to collect data on the programs of LabView and VC ++ at the same time?

    Hello

    There are two programs in LabVIEW and another is in VC ++. The two programs to collect hardware data.

    Therefore, for the experience, it is necessary to begin to collect data at the same time and lag must be

    less than millisecond (it is essential for the experience). How can this be achieved? BTW, I'm new to LabView.

    I think on the use of network socket to get the message for both applications.

    I was wondering if there is a better way.

    Thank you.

    You do not say if two programs access the same material, but I guess not. Because if they did, you probably get conflicts when the two programs try to access the same material at the same time.

  • Use two assistants for the acquisition of data at the same time

    Hello

    I want to read multiple data channels of analog inputs on my DAQ hardware. However, when I try to create two separate data acquisition assistants for each entry, it gives an error saying "is reserved for the specified resource. The operation could not be performed as indicated "." Can't use two assistants for the acquisition of data at the same time?

    I have to add different channels in the same assistant DAQ? I tried, but I couldn't separate the data in different graphs.

    How does this work?

    Kind regards

    Allard

    You can't have multiple tasks of the same type (in this case inputs analog) on the same device.  Just so having 1 DAQ Assistant read all your channels and separate your channels for individual transformation.

  • Non-compliant WMI when retrieving information about the same exact machine

    For some time, WMI has reported the following information some machine:
    Win32_ComputerSystem\Model = "HP EliteBook 8560p.
    Win32_ComputerSystem\Manufacturer = "Hewlett-Packard".

    One day, WMI has reported the following:
    Win32_ComputerSystem\Model = "161A___".
    Win32_ComputerSystem\Manufacturer = "HPQOEM".

    A few days later, WMI is returned for having reported the usual:
    Win32_ComputerSystem\Model = "HP EliteBook 8560p.
    Win32_ComputerSystem\Manufacturer = "Hewlett-Packard".

    I don't have the machine and the user can not explain what might cause WMI retrieve various information.

    How to get Windows in a State where it is retrieved different information about the same PC?
    Is there a way to 'reset' WMI so it retrieves information constantly?

    What similar (and different) for prior experience (different machines).

    The usual case is:
    Win32_ComputerSystem\UserName = DOM-user
    where:
    DOM is the domain of the user (in uppercase)
    the user is the user name (all lowercase)

    But sometimes WMI recovered:
    Win32_ComputerSystem\UserName = DOM- USER
    where:
    the username was all uppercase.   Apparently caused when the machine into hibernation

    or

    Win32_ComputerSystem\UserName = DOM- dom -user
    where:
    the field of user uppercase followed by domain user in all lowercase letters.  Never explained.

    I use WMI to develop an ID for purposes of the license, so it is extremely important that WMi systematically extract information.

    The problem with username is solvable.

    However, the model with randomness and Manfacturer seem more problematic.

    Not valid. This makes no sense and breaks all the rules of scope-resolution. And if it is in a single database, or uses tables in databases, is not relevant.

    Each object must be particularly well identified. If you cannot do this:

    select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a
    

    3 objects cannot share the same alias. Example:

    SQL> select * from (dual, dual) d;
    select * from (dual, dual) d
                       *
    ERROR at line 1:
    ORA-00907: missing right parenthesis
    

    You need to combine objects - by using a join union or similar. He will have to be done as follows:

    SQL> select * from (select * from dual d1, dual d2) d;
    select * from (select * from dual d1, dual d2) d
           *
    ERROR at line 1:
    ORA-00918: column ambiguously defined
    

    However, we need to have unique column in a projection of SQL names - so the join of the need to project a unique set of columns. So:

    SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
    
    DUM DUM
    --- ---
    X   X
    
    SQL> 
    

    I suggest that you look carefully at what opportunities are and how it applies in SQL - and ignore if the referenced objects are local or remote, because it has no effect on the basic principles of scope-resolution.
