Saving hash() in a data store.

Hello

In my view, it is not possible to save a hash() to the data store object.

Pleas confirm.

Get the error below

Error in eapply (x,. ore.extrefobjs, do.reg.finalizer, envlst, all.names = TRUE):

the argument must be an environment

When you try to save a hash in the data store.

Thank you

Swathi.

Hi Jessica,.

I am able to reproduce this in Oracle company R 1.4. Oracle Enterprise R 1.4.1 upgrade will solve this problem.

Kind regards

Sherry

VDR can be saved in a data store

VDR can be saved in a store of data or just on a network share?

How can you save the data store?

Well, we need to create a NEW data store or you can add a player to the VDR device, and put this *.vmdk on a data store, so you use a data store to store backup data. I recommend sharing backup with your VM storage, for reasons of recovery after a disaster.

If anyone knows what I m hurt you showme how please!

Two thoughts:

If you have changed somehow the object type that you want to keep, you must remove the Simulator files before running again.
How about you provide a clue as to where the class cast exception that happens? You are more likely to help in this way.

Where temporary target data stores are save?

Hello
I took two sources. A source of oracle DB, second source of flat file and then I took the temporary target as data store.
After successfully running session, I want to see temporary target data warehouses. Where the temporary target databases are saved?
Please help me.
Thanks in advance,

I had the answer... When we target as a "temporary database. After run the interface what it will look like "yellow interface. This yellow interface is the stote of temporary data. We can use this temporary database as 'the source table.

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)
{
  //System.log("-> LUN: " + scsiDisk.canonicalName);
  for each (var dataStore in u_host.datastore)
  {
  if (dataStore.info.hasOwnProperty("extent"))
  {
  for each (var scsiDiskPartition in dataStore.info.vmfs.extent)
  {
  if (scsiDiskPartition.diskName == scsiDisk.canonicalName)
  {
  o_diskHash.put(scsiDisk.canonicalName, dataStore);
  }
  }
  }
  }
}

return o_diskHash;

// getScsiDisksKeyedByLUN
var o_diskHash = new Properties();

for each (var scsiDisk in u_host.config.storageDevice.scsiLun)
{
  o_diskHash.put(scsiDisk.canonicalName, scsiDisk);
}

return o_diskHash;

// in workflow
for each (var can in dstoreMap.keys)
{

Not enough space on the data store. Could not power on VM:No space available on the device

Hello
Here's my problem. I have several virtual machines. But one of them can be powered on because of the problem of space. I can not add spaces because there is nothing to add. The data store is only 760 MB left. There is summary information about the virtual machine below. I need power somehow on this machine, but how can I do. can I add another data store space. Y at - it files I can delete from the data store. Snapshot file is considerably large, I can reduce its size without changing anything.
Thank you.

There are several ways to approach this problem

1. you can storage vmotion, some VMs who are currently used and this will free space.

2. check the clichés that you don't use, and delete those.

3. reduce the memory of some other virtual machines which are turned on so that the swap space can be saved.

Script in time of latency list vm e/s and the data store the virtual machine is on

Hello. We have a vsphere 5.0 environment and we live a latency of IO heavy. I'm looking for powercli script will get the latency of i/o for each virtual machine and get the data store name, to what it is now. We will access our storage on optical fiber. I'm trying to get a good overview of the latency of IO in a nice view in a csv file. I found what could be a good basis to https://communities.vmware.com/thread/304827?start=0 & tstart = 0 , but I'm not sure how to get the name of the data store in the table and I think that it is written to the nfs in any case storage. Thanks in advance for any info\advice!

Try the next version, it includes the average latency time read/write for the virtual machine and PAHO are / s average for the virtual machine.

Since the CSV has a row for each data store, the values for the virtual machine are repeated.

I also added the host name

$vmName = "VM*"

$stat = "datastore.totalReadLatency.average","datastore.totalWriteLatency.average",  "datastore.numberReadAveraged.average","datastore.numberWriteAveraged.average"$entity = Get-VM -Name $vmName$start = (Get-Date).AddHours(-1)

$dsTab = @{}Get-Datastore | Where {$_.Type -eq "VMFS"} | %{  $key = $_.ExtensionData.Info.Vmfs.Uuid  if(!$dsTab.ContainsKey($key)){    $dsTab.Add($key,$_.Name)  }  else{    "Datastore $($_.Name) with UUID $key already in hash table"  }}

Add the total size of data store and space remaining
```
Hi,

What would be the easist way to add the total datastore size and remaining datastore size to the following.
I do emphasise, esasiest, since I'm as green as can be to powercli, powershell for that matter. I'm trying to learn in babysteps 
```
Get - VM $VM | %{ $_. Name; ($_ | get-datastore | select name). Name}
At the moment I get day like this, I get to the above.
DataStoreName (Add info here on DS size?)
vmname
DataStoreName (Add info here on DS size?)
vmname
...
...
...
Thank you!!

The $_ represents the object that has been passed through pipeline (the ' |') of the previous cmdlet.

For example

Get - VM | %{$_. Name}

The cmdlet Get - VM will get all the VMs on the servers of vSphere to which you are connected.

The pipeline ('|) ') said these VM objects one by one to the following code.

In what is a Foreach-Object (alias is '%') who will send the name of the virtual machine (available in the variable $_) to the default output.

On a Select-Object cmdlet, you can select properties of the object that was passed through the pipeline, or you can use what is called a "calculated property. Such a calculated property consists of a pair of hash, name (N) and Expression.

Obviously, name is the name you want to give to this calculated property.

Expression is the block of code that must be executed.

For example

Get-Datastore. Select Name,@{N="CapacityGB; E={$_. CapacityMB/1 KB}}

All database objects are passed to the Select-Object cmdlet.

The Select cmdlet displays the name of the data store, and it will display a property called CapcityGB, which displays the ability to store data in GB.

Notice how the property CapacityMB that is present in the data store object is converted to GB by the code in the Expression block.

The part of the Expression has not always need to do something with a property of the object that was passed.

For example

Get - VM | Select Name, @{N = 'Current time'; E = {Get-Date}}

In this case the Select-Object cmdlet displays the Name property of the virtual computer object that has been sent.

And it will display the current time as the propertyname "current time".

This is an example of a calculated property that has nothing to with the object passed through the pipeline.

I hope that clarifies the code a bit.

get the names of Get-ScsiLun data store

$row.vendor = $_. Name of the vendor
$row.model = $_. Model
$report += $row
}

Thank you very much, Kev - o

Try it like this
```
$esxName = "esxsrv1"

$dsTab = @{}
foreach($ds in (Get-Datastore -VMHost $esxName | where {$_.Type -eq "vmfs"})){
    $ds.Extensiondata.Info.Vmfs.Extent | %{
        $dsTab[$_.DiskName] = $ds.Name
    }
}

$report = @()
Get-ScsiLun -VmHost $esxName -LunType "disk" | %{

    $row = "" | Select Host, ConsoleDeviceName, Vendor, Model, Datastore    $row.host = $esxName    $row.ConsoleDeviceName = $_.ConsoleDeviceName
    $row.vendor = $_.Vendor
    $row.model = $_.Model
    $row.Datastore = &{
        if($dsTab.ContainsKey($_.CanonicalName)){
            $dsTab[$_.CanonicalName]
        }
    }
    $report += $row}

$report |Export-Csv c:\Temp\results.csv -NoTypeInformation
```
The script begins by creating a hash table where he maps the CanonicalName with the DatastoreName.

In the 2nd part of the script of the hash table is used to find the DatastoreName through the CanonicalName.

The data store could not be found.

Thank you.

Your destination data store is set incorrectly

VM_BACKUP_VOLUME = VMFS/Synology.

It should be

VM_BACKUP_VOLUME = / vmfs/volumes/Synology.

partedUtil get /dev/disks/mpx.vmhba1:C0:T1:L0
35697 255 63 573480304
What is - this? change this? which?
I have download parted (gnu) but everything installed try I get "configure: Permission denied ' suggest?
I try KB (1009565)
and I get this:
~ # vmkfstools Pei /dev/disks/mpx.vmhba1\:C0\:T1\:L0

but fdisk 'can not read... ". »
Please help with suggest another way...
Thank you!

There is a road to try to recover partition?

That's why I suggested to run the ACU. To check the controller has all the problems and presents the logical volume properly to the operating system.

Block size is too small - reformat the data store or create files VMDk 2?

Hello
I'm new to VMware and so far I absolutely love everything about her! Well, I was not too happy when I realized that I can't create more than 256 GB a drive without reformatting the VMFS datastore. Apparently, I accepted the block size of 1 MB by default during the installation... I now need to configure a file server with about 500 GB of storage. The data store with a larger block size (4 MB would be fine for me) reformatting is easy enough? I am currently working on the first host ESXi 4.1 and will move to set up 2 more hosts in the coming weeks. I read somewhere on the forum that ESXi 4.0 doesn't let you change the block size by default of 1 MB - is this true or relevant to 4.1?
Currently, I have only 2 small VMs on that host, and these can be easily saved and put offline for a few hours, if necessary. When starting the server, I created a single RAID array that holds ESXi and all virtual machines - does that mean that I have to reinstall ESXi in order to increase the size of the block?
An alternative that I can get to is to simply create 2 255 GB VMDK each and load distribution of storage in the guest operating system (Win 2008). Performance wise, is a disc more great and better (or worse) than the two smaller disks?
On a related note, what should I choose for the "Independent" option when you add a new virtual disk? Default is disabled (not independent).
Your thoughts, focus and expertise are welcome and will be greatly appreciated!
Thanks in advance,
Dothan

Dothan,

You should power (after the virtual machine backup) remove the current data store and create a new one with the new block size. I did not have this on ESXi 4.1 again, however, he worked on ESXi 4.0.

The maximum size of VMDK. If you want ot be able to take pictures, make sure you subtract twice the size of block in GB of the documented maximum size.

Block size 1 MB--> 254 GB (= 256 GB, 2 GB)

Block size of 2 MB--> 508 GB (= 512 GB - 4 GB)

Size of block 4 MB--> GB 1 016 (= 1 024 GB - 8 GB)

Block size of 8 MB--> GB 2 032 (= 2 048 GB to 16 GB)

EDIT: Just the KB for the maximum sizes. http://KB.VMware.com/kb/1012384

Prevent write access to a data store

All,
I hope someone can advise me on this problem?
The scenario:
We have introduced a new LUN in our ESX 4.0 cluster, configured as a data store VMFS and storage vmotion to migrate from a number of virtual machines on this data store. Each virtual machine is turned off. Logic unit number is presented an IBM DS8100 storage array. At a specified time, the LUN is migrated to a remote data center, where we intend to present the LUN to a cluster of replacement and saving virtual machines on this LUN. This provides a method of migration of virtual machines between remote sites.
The problem is when we test this guy storage advise that there are tracks out of sync in the replicated data, which they claim is due to the LUN writes during replication (which seems unlikely that all the virtual machines on this LUN were stop). According to me, the question is at the end of storage but have been asked to determine if there is a method to isolate completely the LUN of the cluster ESX source to ensure that no data is written during the migration.
The methods that I have considered are:
(1) delete the data store - not a viable option that he would destroy all data on the LUN.
(2) turn off all the paths to the data store by using the vSphere client. It resembled a possibility - I can deactivate 3 of the 4 paths to an ESX host, but get an error when I try to disable the fourth.
(3) use esxcfg-mpath to disable paths - not convinced that this will work any different use of the GUI.
(4) get the guys from storage to use to prevent ESX hosts to 'see' the LUN of LUN masking. My problem with this is how ESX will react if she can't see the data store.
My question is, is anyone know of any method I can use to ensure that this LUN cannot be written in during the migration to the remote site?
Many thanks in advance,
Martin

Yes, ESX will complain, but once you log LUN return - everything will be ok.

Remove the inventory of VMs (but don't delete disk) before disconnection LUN and ESX will not say anything.

root properties in the connected data store: error when accessing the date/time storage

When you browse the properties my connected data store I get an error message when you try to read the value of the property of 'storage date/time': object doesn't support this property or method.

Here is a minimal example:

Dim oMyDataStore, MyProperty, oMyProperties

Set oMyDataStore = Navigator.ConnectDataStoreByParameter ("TOC", "" & "C:\Program Files (x 86) \National 2012\Examples\Data\Example_data.tdm" & "" ')

Set oMyProperties = oMyDataStore.RootElements (1). Properties

For each MyProperty in oMyProperties

  Call MsgBoxDisp ("property name:" & MyProperty.Name & + "\n"&"property value:" & MyProperty.Value "")

Next

Why can I not access this particular property by default?

Hi Phex,

for the date/time properties, an object called UsiTimeDisp is returned. This object allows to that extend features of service as access to each part separately (day, year, hour, seconds,...) of your date/time value. If you want to print the value of time with MessageBoxDisp, you can use the VariantDate this object property.

Your code might look like this then:

Dim oMyDataStore, MyProperty, oMyProperties

Set oMyDataStore = Navigator.ConnectDataStoreByParameter ("TOC", "" & "C:\Program Files (x 86) \National 2012\Examples\Data\Example_data.tdm" & "" ')

Set oMyProperties = oMyDataStore.RootElements (1). Properties

For each MyProperty in oMyProperties

  MyProperty.DataType = eTime Then

    Call MsgBoxDisp ("property name:" & MyProperty.Name & + "\n"&"property value:" & MyProperty.Value. ' ") VariantDate)

  On the other

    Call MsgBoxDisp ("property name:" & MyProperty.Name & + "\n"&"property value:" & MyProperty.Value "")

  End If

Next

I hope this helps.

Good day
