Not clear about the number of allowed hosts

• Get-vmhost does not reflect the number of correct hosts on a few scenarios

  Hello members of the community.

  When I try to use the cmdlet get-vmhost against a cluster that has one or no hosts in there, I don't get the number of correct hosts. Here are some lines for this information.

  foreach ($objDataCenter to $objColDataCenters)
  {
  $objColClusters = get-Cluster-location $objDataCenter

  foreach ($objcluster to $objColClusters)
  {
  $Details = $Null
  $objClusterBaseRP = $objHosts = $objDataStores = $objVMs = $Null
  $intNUmDatastores = $intNumHostCPUs = $intTotCPUMhz = $intTotUsageCPUMhz = 0
  $intTotMemMB = $intTotUsageMemMB = 0
  $CPUStat = $CPUStatMax = $MemoryStat = $MemoryStatMax = 0
  $intTotMemGB = $intUsageGB = $intMemResGB = $intMemLmtGB = 0
  $inttOTDiskCapacityMB = $intTotDiskFreeMB = $intTotDSCapacityGB = $intTotDSFreeGB = 0
  $intTotVMMemGB = $intTotVMCPUMhz = $intNumVMCpus = $intTotVMMemMB = 0
  $intTotVMProvisionedSpaceGB = $intTotVMUsedSpaceGB = 0

  $objHosts = get-vmHost-location $objcluster

  $objHosts.Count

  }

  }

  code above produce white for clusters that has one host for all other groupings that has 2 or several hosts results are correct. I know that there is no point of having a single node cluster or not, but the result does not reflect his decent stats.

  In the same way under lines also produce incorrect information to the cluster that has no HOST or a single HOST that is in maintenance mode and has no inside VMs

  $objVMs = get-VM-location $objCluster

  $objVMs | %{
  $intNumVMCpus += $_. NumCpu
  $intTotVMMemMB += $_. MemoryMB
  $intTotVMProvisionedSpaceGB += $_. ProvisionedSpaceGB
  $intTotVMUsedSpaceGB += $_.usedSpaceGB
  
  }

  When I print the values of all the variables above, it should report 0 instead I have the chance to see some numbers. Please note I have explicitly assign values $null to all objects and 0 in all other variables at the beginning of the loop for clusters.

  Any help to solve this is greatly appreciated - thanks

  Hello, Ramkrish-

  Welcome to the communities.

  For the first part, the number of hosts in a cluster with zero (0) or one 1 host - there are a number of things happening there.

  When the Get-VMHost call returns only one host, and you then try to access to the. Property of the count of $objHosts, you try to access this property on an object VMHost, not an array of length 1 with a VMHost inside.  And, since the VMHost object has no property '. " Count' you get a return of the 'white' or null.

  And when Get-VMHost will return no host, and you are trying to access. Count on $objHosts, you effectively type '$null. "Count", since $objHosts - eq $null at that time.

  Two ways to handle these cases would be to use the Measure-Object cmdlet or explicitly to a table, even if zero or one VMHosts are returned.  As:

  ## using Measure-Object$objHosts = Get-VMHost -Location $objcluster($objHosts | Measure-Object).Count    ## correctly returns 0 or 1 (or greater)...## or## forcing an array, even if 0 or 1 items returned$objHosts = @(Get-VMHost -Location $objcluster)$objHosts.Count        ## correctly returns 0 or 1 (or greater)...
  

  Regarding the behavior you're seeing with the statement Foreach-Object with $objVMs, I suspect that the behavior of the Foreach-Object statement when you're running an empyt null him is at stake here.  In other words, while you can imagine "$arrEmptyArray | % {'Hello'}' to produce anything, happening actually by an interation of the loop (really - try - the).  So to avoid this, you can delete the unnecessary part that stores the output of Get - VM in the variable "$objVMs" and combine the lines to channel the output from Get - VM directly to the Foreach-Object statement, as:

  Get-VM -Location $objCluster | %{    $intNumVMCpus += $_.NumCpu    $intTotVMMemMB += $_.MemoryMB    $intTotVMProvisionedSpaceGB += $_.ProvisionedSpaceGB    $intTotVMUsedSpaceGB += $_.usedSpaceGB}
  

  By the way: while we're updating this code a little, another way that you could get these totals is again using the Measure-Object cmdlet, this time with the parameter - sum, as:

  Get-VM -Location $objCluster | Measure-Object -Sum -Property NumCpu, MemoryMB, ProvisionedSpaceGB, usedSpaceGB
  

  Much more compact and allows just of PowerShell do the work.  Although you then maintain the return of the object of measures, depending on the situation, it is quite practical.

  How about that?

  How it works is usually the application (explorer.exe is an application) in question is open about everything that monitor his last (final) session was closed the.  Not all applications have this built-in memory, but most do.

  I don't think that even something TO manage multiple monitors (this is what it was built for) will do what you are wanting.  ;-)  I see no way of programming of this type of automation.  ;-)

  About the LOCATION of keyword, the documentation says

  The LOCATION keyword specifies an operating system specific path name

  Cannot give us just a destination filesystem as/u04/arch_logs without the keyword RENTAL. What is the advantage in specifying the keyword LOCATION?

• Not sure about the best way to structure my app.

  Hello

  I'm not sure of the best way to structure my app.

  I have a main menu that links to 3 submenus, each a link to a number of pages. Initially when I clicked on a menu button, that he would open a submenu instantly and then clicking a button, the page open instantly. And return to the previous menus was also very fast.

  But at some point that he started getting really slow. I click on a button in the main menu and he thinks for a while before moving on to the pick-me-up submenu is too slow. I'm not sure why and I lose a lot of time trying different ways to do it.

  So what I want to know, as far as efficiency goes, should I create the main menu and submenus 3 at the start of my application, keep these same objects active and just pass pointers to them around like settings and pop on and off the screen of the battery when required, or should I just create them as new items whenever they are needed?

  Any advice on this would be greatly appreciated.

  If each submenu returns to the main menu, just use the screen for the navigation stack. Don't forward mainMenu for the submenus; to return, just pop the submenu and the main menu will be back at the top. At the time of mainMenu wants to open a submenu, just push without fun first.

• Expression regular-not clear for the result

  I have written 3 applications using regular expressions, but I'm not very clear on the outcome. Looking for help to understand the logic.

  3 > SELECT REGEXP_SUBSTR ('APT-101, BLDG 34, community xyz, XYZ ROAD, BANGALORE - 560066',(^'[[:alpha:]]+) ') ADDR FROM DUAL;

  All requests above returns the same result, i.e. 'APT '.

  I can somehow convince myself that regular expressions - ' ([[: alpha:]] +)' and ' [[: alpha:]] +' in the given scenario may return the same string that is 'APT', but in the last query the regex ([[: alpha:]] + is preceded by ^, which according to my understanding should return something that isn't ONE or MORE CONTINUOUS OCCURRENCE OF ALPHABETS, but even this query is retune "APT".)

  In expressions regular, curved brackets can be used for the Backreferences, for example \1 can be used to return to exactly what corresponded to the subexpression inside the 1st pair of parentheses.  You are not using anything like \1 here, so this backreferences do not apply to this question.

• not visible on the ESXi LUN iSCSI hosts

  So I have a bit of a strange and hoping the community can help me to understand. In my lab at the House, I have 3 x ESXi 5.1 Build 799733 hosts x 2 guests are the same hardware (BUD Intel) and the other host an old HP flat desk. I am running CE Nexenta 3.1.3.5 on a Microserver HP which provided the iSCSI storage to HP desktop computer. The 2 new Intel NUC VMware hosts however, I am unable to get any iSCSI storage visible to them. Software iSCSI adapter is enabled, peut vmkping storage to the host and the target will appear on the static discovery tab. The configuration appears to be identical between the 2 However, the hardware is different... I have a new analysis on the host and no devices appear. Now the obvious answer is there must be a security issue on the side of Nexenta... but the 3 hosts are all part of the same group initiator. Confirmed and copied the IQN name over and over again. I still think that this is maybe a matter of Nexenta, but maybe it's something else.

  Check the vmkernel.log file contains the following information after a new analysis...

  (2013 06-09 T 23: 49:06.160Z cpu3:2933) VC: 1547: device rescan time 17 msec (total number of 5 devices)

  Problem solved.

  Appears that it was a problem of connection iSCSI ports. There is only a single teddy bear in each of these hosts and allowing the port bindings vmkernel on initiator iSCSI under 'Network Configuration' result not being iSCSI target devices is not visible. Removed the vmkernel port binding and made a new analysis. Cameras then showed upward.

  Hello everyone,

• VM starts not directly from the CDROM drive ESXi host

  Hello. I was looking for a long time another discussion for people who have had the same problem, I found it but the answers that the candidates are not useful for me. I explain my problem giving you as much information as I can.

  I have created a virtual machine in order to intall inside Windows Server 2K 3. The problem is that I can't make the start of the VM from the CD I put in the ESXi host CDROM drive. I installed ESXi 3.5 U4. For the virtual CD/DVD Drive 1 (only in the virtual machine), I chose "Host device" as the device Type.  The only option, it's for me inside this option is ' / vmfs/devices/genide / vmhba0:0:0.» The message I get in the console view is "Not found operating system"

  Storage adapters I in the ESXi host are: LSI1068E - & gt; vmhba2 where I see my RAID1 disk1. The other device is ICH10 4 port SATA IDE Controller - & gt; vmhba0 where I see the physical CDROM Drive.  I also have another device that is "USB Storage Controller" - & gt; vmhba32 where I also see the CDROM (but when I create the virtual machine does not allow me to choose this controller, vmhba32:0:0). This controller is a "SCSI" where alumni are "Block SCSI".

  I have also checked the box "connect to power on" in the settings of VM window. The CD booteable because unless I restart the ESXi host and I do boot from the CDROM it loads the Windows Setup program. Thus, the CD is OK and the CD-ROM drive is also OK.

  I don't know what to do and what to test. If I choose to boot the client machine, the virtual machine option starts ok. The problem is that I need to transfer all the contents of the CD by the network and right now I am using an ADSL connection.

  The server I have is IBM System x 3650 M2, which is compatible with ESXi 3.5 U4.

  I know I have another option is to boot from and ISO image. Here, I have a few questions. First of all, how to download the ISO to the ESXi host image? Do I have to use the RCLI? Secondly, I want to make sure that only a problem of booting from the CDROM or the problem is maybe the ESXi of CDROM drive is not recognized by ESXi, so I'll never be able to use it.

  Advanced averybody thanks.

  The discussion has been moved to the VI: forum ESXi 3.5.  It seems to be the case, but could check you that ESXi is load the IDE driver for the ICH10 controller?  This mode is the controller of the value in the BIOS?

• Question about the location of a host of virtual machines

  I work on temporarily to change the behavior of the DRS for a particular VM (in VI Perl), but my question is more general research of the root 'to host' for a particular virtual machine.

  The installation of the infrastructure program:

  + Folder1

  - + Cluster1

  -

  ---

  + Esx1

  -

  ---

  + VMs

  -

  ---

  + Esx2

  -

  ---

  + VMs

  .. .etc

  There are several clusters on different servers in this configuration.

  In order to manage the DRS by VM, I find the cluster that hosts the virtual machine.  The $vm_view - & gt; parent returns one 'value' (other than the name of folder) folder.  It seems that the only way to match the virtual machine to the cluster of accommodation is to do a brute force search, open multiple views and retrieve the values of each until I have a match, and then looking through each cluster in the corresponding folder to find the one that contains the virtual machine.

  Am I wrong?  It is an ugly and ineffective way to find the host for a virtual machine.  If I am not mistaken, are there plans for the addition of the hierarchy of the path to the view of the VM?

  A $view - & gt; config - & gt; value of path containing something like: file - & gt; Cluster - & gt; ESX Server - & gt; VM would be useful.  In addition, a function which maps values of resources to names of resources would be very helpful (with a code depend on a 'value' of the 'field-c125"and any other code that depends on a 'name' of"Cluster1"creates a lot of extra work).

  Thank you

  -David

  You can determine the Cluster that host a virtual machine by browsing through the ResourcePool of the virtual machine. Owner of the ResourcePool is the ClusterComputeResource who manages the virtual machine.

  $vm_view-> resourcePool->owner

  Also, to get the HostSystem that contains the Virtual Machine, you can follow the path

  $vm_view-> run-> home

  Regarding your suggestion to have a predefined path to access a managed entities, we have after explanation.  There are different paths through which you can access to the different managed

  entities of your inventory according to its hierarchy. Virtual Infrastructure gives you the flexibility to design your inventory. You can add a folder or host or a Cluster directly to your data center.

  Then it still allows a folder to have three objects as its child entity. If the path for any entity depends on the structure of your inventory. If a path can be set.

  All managed objects are uniquely identified managed objects ID. Name can be dupilcate for few entities in a data center, you can have two Resourcepools with the same name in different groups. Similarly, you can even named so that each entity is mapped using an object ID, and not a property 'name '.
