• PowerCLI Script required to identify all clusters in a data center and all hosts within each cluster and calculate it using cpu and ram, avg, min, and max.

  Hi all

  I'm new to powercli and try to create a script to list all clusters in a data center and all hosts in a cluster and calculate min, max and avg cpu usage and ram by the host and cluster. So far, I have tried the below but I can't publish the results of my script.

• Create a VMFS and add it to all hosts in a cluster

  Hi, I'm trying to create a script in order to create a data store and then present it to all hosts in a cluster.

  any idea?

  Add-PSSnapin "Vmware.VimAutomation.Core".
  # - Create Variables -
  #$vcenter = %1
  ##---Connexion to the VirtualCenter-
  $Server = $args [0]
  $ClusterName = $args [1]
  $VMHost = {get-Cluster $ClusterName |} Get-VMHost}
  $Name = $args [2]
  $Path = $args [3]
  SE connect-VIserver $Server

  Get-VMHost $VMHost | New-store data-Server $Server - name $Name - path $Path - Vmfs-confirm: $false
  Get-VMHostStorage - $VMHost - RescanAllHba - RescanVmfs-r VMHost

  You must be connected to the Cluster Get

  You need not create the data store on all nodes of the cluster.

  Just 1 host is sufficient.

  And the creation of a new store of data forces a new analysis.

  So that should be enough

  Add-PSSnapin "Vmware.VimAutomation.Core" ## ----Créer les  Variables----#$vcenter = %1## ----Connexion au VirtualCenter---- 
  
  $Server = $Args[0]$ClusterName = $Args[1]
  

  Connect-VIserver $Server
  

  
  $VMHost = Get-Cluster $ClusterName | Get-VMHost | Select -First 1 
  
  $Name = $Args[2] $Path = $Args[3]  Get-VMHost $VMHost | New-Datastore -Server $Server -Name $Name -Path $Path -Vmfs -Confirm:$false
  

• Script to pull the last timestamp spend all hosts in a cluster?

  Hi all

  Lately I have seen an issue where my host 5.1 logging abruptly stops and the other remote access to every host I have no way of knowing what happened.

  Is it possible to account for the last, for example hostd.log timestamp for each host in a cluster?

  Thank you

  Tony

  Try something like this

  foreach($esx in Get-Cluster -Name MyCluster | Get-VMHost){  $log = Get-Log -Key hostd -VMHost $esx  $esx | Select Name,@{N="Last entry";E={[datetime]($log.entries[-1].Split(' ')[0])}}}
  

  But be aware that fetch a newspaper of the ESXi could take some time.

  The script needs get the full log, to be able to extract the last line

• License question - do need me a VSAN license for all hosts in a cluster?

  I have a 6 host cluster exist using the VSphere Essentials Plus package with a single server VCenter. Can I buy x VSAN 3 licenses, for example to add the storage to the 3 hosts I have install the VSAN license on and access the VSAN of the 3 other hosts in the cluster data store? (Assuming only 1 CPU for each host.)

  Thank you!

  Hi Daniel,.

  Since Virtual SAN is activated at the level of a cluster, all cluster hosts can consume storage since the virtual SAN data store regardless of how many guests contribute to storage. So to answer your question, you need all 6 hosts in your cluster license, even though only 3 of them contributed storage.

  Also note that the licenses are per CPU so in your scenario if each host has 2 CPUs, you need a total of 12 CPU licenses. I hope this helps.

• Good way to stop and run again a FPGA reference

  Hi guys!

  I have some problems when I try to stop, and then rerun an FPGA vi, I explain.

  I have two DMA FIFO to send data to the FPGA of the CPU and the CPU for the FPGA. When it receives data, the FPGA treats them and sends them to the CPU, and according to the result of the CPU does something. For example, it can be turn on LEDs or to rotate a motor continuous.

  But to do these actions, I have to use a "personality FPGA", i/o pins and LEDs appear to be managed by the FPGA core. So I have to close my reference vi FPGA in charge to receive data from the CPU, make my power on LED and then after raise again my FPGA VI once again, if I don't do LED blink or stay without effect rotation motor... But close and start again the FPGA VI creates problems when running, especially for the previous reading on the FIFO DMA awaiting... I tried to intercept errors on the FIFO to restart the FPGA VI with a good time but nothing... I am lost and I think Miss me something, concept, or something else.

  I can't share my code because I work for a company, but I would like to know if you have VI with this type of structure: a FPGA reference that must be stopped to allow interaction of material with the FPGA default personality then run again, all with good timing...

  I hope I'm clear, but if it is not the case, I can rephrase if necessary.

  Thank you very much for the help!

  Afghow.

  I do not understand why you need to change the bit file is loaded in the FPGA.  Why you cannot add code that handles the inputs/outputs to your FPGA processing?  Why do you still need to send data to the host (CPU)?  Just having the process FPGA data and change the output directly.

• Is there a good way to find all references to a table or a column?

  I have recently inherited an application large apex and receive requests to make changes.  I would like to ensure that any changes that I could do on a table or a column in a table affect application pages which I think are involved.  However, demand is high, and I'm assuming that it is possible for other pages may refer to the same column or table, and I was not aware of these references (at least until after he breaks once I have change the column or table).

  My question is this: is there an integrated report, or a way to query apex, who will tell me ALL references to an application to a particular table or column?  This way I could fix all pages in the application, rather than waiting to break.

  Thank you!

  John

  John,

  Look to the upper right while in the Application Builder, for the area of the search Application .  Enter any string you want and APEX will search to find and view a report that contains a link.  Click the link and APEX will show the page and control chain concerned.

  Here's another way; query the table APEX seen through this code:

  SELECT workspace,
         workspace_display_name,
         application_id,
         application_name,
         page_id,
         page_name,
         region,
         item_name,
         display_as,
         display_sequence,
         item_label,
         db_column_name,
         db_table_name,
         help_text,
         item_id
    FROM apex_application_page_db_items
  WHERE     workspace = :workspace
         AND db_table_name = :table_name
         AND db_column_name = :column_name

• Version of the host of all hosts in a Cluster or a vCenter

  Hi guys,.

  Our environment has got more than one host to multiple clusters. I'm trying to get a report include a list of host names in a cluster or a vCenter server & ESXi version of each host.

  Could you please suggest me the best way to get that report either via vSphere client of power CLI command

  Kind regards

• List of all hosts in a Cluster, the Local single data warehouses

  I had a few attempts but failed miserably.

  Can LucD - you help maybe?

  I just need to list each local VMFS Datastore and ideally have each size. The idea is to get this info in a separate calculation in a hash table, something like this:

  @{N = "Datastore"; {E = {* list all the Local DS for the host that is currently being questioned and their respective sizes in here *}}

  I hope I explained well enough...

  Thank you very much!

• all hosts on the same page

  Hello

  on 5.6.4 I created a report of active host summary.

  I have four monitored servers. Then I have 4 pages. A host by page.

  Can I have all on the same page?

  I mean a single page for 4 guests.

  How?

  Thank you.

  The report of "Hosts" of the cartridge of the infrastructure, or other reports host designed for this purpose, is the best way to present all hosts on a single page.

  This is the PDF of the report "Hosts": exit

• Script to stop all instances of weblogic running on a box

  Hello
  
  There the script to stop all instances of weblogic running on a Unix machine at a time?
  
  My understanding is grep for weblogic and then issue kill-9 process.
  
  Correct me if im wrong and also provides good script to stop all instances of weblogic.
  
  Thank you!!

  Hello

  You can use simple JMX code to achieve the same (all servers within a domain at a time stopping):

  Topic: Force Shutingdown WLS using JMX
  http://middlewaremagic.com/WebLogic/?p=55

  NOTE: The code above JMX is supposed to close just down the AdminServer, you can remove the if {} block of line no-60 the following code JMX stop all servers rather than to stop only the server administrator.

• What is a good way to say WHAT HA is healthy?

  Go to the essential, how will I know if HA is happy and healthy for all hosts in a cluster?

  We are very new to ESXi/ESX/vCenter. We have the license for HA, etc. Most of the things are fine, but we had a problem with vCenter box recently and it hung (vCenter box runs on a server ESXi unrelated to our production cluster. The problem was caused by... you guessed it, NTP problems... we had NTP works fine on ESXi hosts in our production cluster, but the vCenter box is completely separated physically and virtually our production of HA cluster and we have neglected it). After restarting the host to vCenter, he came and began to cough up all sorts of errors of heart rate for all hosts and some mistakes HA of a single host. Could not find anything wrong b/c, everything seems to work very well. So I restarted the VM vCenter, and when it came 10 minutes ago he seems happy. No more alarms/errors not yet at this time.

  So I expect errors to start popping up at all now, but if there is nothing, how do I know if HA is happy?

  You can see the newspaper on each ESX:

  tail-f /var/log/vmware/aam/vmware_*.log

  HA is happy when all heartbeats works... do not forget to have redundancy of the network, if you have only 2 node ESX make sure default gw is to ping queries (or add additional tests of 'ping'), understand admission control (if using it),...

• Raw disk used by the prompt on the same host, broadcasts available on other hosts in the Cluster

  We have a Cluster of MS using RDMs in a host cluster ESXi 4.1 5.  The RDM physical Mode, on a guest on hostA, the storage is presented to the host b, hostC, pass, hostA, hostE.

  It has always been my understanding (and I saw with other RDMs in the past) when a ROW gets used by a hostA of comments, it will be posted is no longer in the pool of strage avalible under the window "Add Storage" on the host b.-e... I would still be able to see as RDM LUN if I went to a guest and added another hard drive, but the host would no longer display it as storage avalible.

  It is confirmed in the following article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1016222

  In my scenario, I can still see the storage that has been given to a guest on HostA as a RDM on hostsB-E in the add storage window. (this cause some problems when let storage recover 'unused' LUNS and storage that has been considered as non-allocated was actually released several guests as RDM.)

  The article suggests that this occurs when the storage is not presented consistently on all hosts in a cluster.  We use EMC FC storage, and my storage administrators swear that LUNS are the same for all hosts in my cluster.

  I search in the KB articles information and empty to come... I'll open a case with VMware, but was wondering if someone else has experienced problems similar, and that has been done on your side to solve (and hopefully help someone to avoid any similar problems)

  In addition, there is an easy way to compare points of view "Add Storage" of all hosts in a cluster to verify that they see the same unallocated storage?

  No, if the number of LUNs and the naa numbers game (don't forget the 16 and the last 8 digits of number of naa are still the same according to the table), you can have row filtering disabled Please check

  The values below the default values are true

  • In the vSphere Client, select Administration > vCenter Server settings > Advanced settings.

• Photo constantly order of photos in a slideshow changes no matter how many times the movements of the user the photo back to the good look at an order. Example: Bathroom Plans eventually grouped with pictures of kitchen! I have found no way to stop this o

  Apple Photo 1.3 serious problems - how can I SOLVE all these problems?

  (1) breaks down without rhyme or reason no matter where I am in the workflow.

  (2) pictures will not be Shut Down Every Time, even after several days of waiting.

  (3) aPhoto frequently badly chooses picture in the EDIT picture option, I get a picture different than the one I clicked on which is on a 100 pictures in a row.

  (4) picture constantly order of photos in a slideshow changes no matter how many times the movements of the end user the photo back to the good look at an order. Example: Bathroom Plans eventually grouped with pictures of kitchen! I have found no way to stop this weird behavior! Is there a way to stop this? If I drag the photo again some 7 additional photos in the slide show, after a minute or less, he appears again to where it was it not. !@#$%$#

  (5) If you make any CHANGES to a photo, it often changes the appearance of your complete slideshow of this picture with impatience. So you lose all this not work fix your configuration of the slide show. Even changing the order of photos once more that I had put back where they should be. !@#$$#@

  (6) photo identifies often shades of lamps and long door handles as the faces of the people.

  (7) photo made bad decisions when it comes to brightness, contrast and colors effortlessly around other than to use other software, where as with iPhoto there was a lot of workarounds. I could continue, but will save one who might be reading of this.

  I am up to date on all updates for my Mac. If anyone have REAL answers so please spilling the beans, but according to me, it's the only truth is that Apple has rolled out a product inferrer to replace an exceptional product, called iPhoto, which does not work on my new iMac computer 5K of 27 ".   If I knew what I would have chosen another computer that I use iPhoto to prepare more of fifty to sixty thousand photos in a given year and I use iPhoto to make hundreds of slideshows from it.  Are there plugins for Photo 1.3? I ask because I see where there could be Add-ons, but I can't find.

  Apple has taken a serious decision by turning his back to iPhoto and tens of millions of loyal users.

  Thanks in advance to anyone brave enough to tackle this job.

  First, back up your library of Photos and hold down the command and option keys while launching Photos - repair your database - you have a corrupted database

• good way to low environment vSphere all maintenance

  Hello

  I want to know what is the right way to lower all vmware infrastructure vspher

  I think it should be in the following order

  (1) lower all the VMS except vCenter

  (2) disable all hosts except running vCenter

  (3) then turn off the vCenter

  (4) connect to the ESXi host left and shut down that host

  (5) then we can stop the shared storage

  Am I wrong?

  We have 10 Server ESXi and vCenter 1

  do this process of changes if we use the money distributed vSwitch?

  Thank you

  I'm not sure if this will affect your virtual machines, but it is recommended (VMware Best Practice) to turn off your HA, DRS, and DPM in your vCenter to avoid any problem will be your maintenance may cause.

  in my experience, I always cut them and vMotion the DC DHCP and vcenter in one box so that I can have this ready next time as I raise the servers and hosts.
