• Number of hosts per LUN

  Hello world

  I've never really thought about it until I started going through some of the design books that are out there.

  This is all based on what I read in here.

  It is recommended to stick to a dozen or so hosts per cluster and you should connect to not more than 8 guests in a single LUN.

  If I follow this guideline, which is good practices about which 8 hosts, I decide to connect to a given LUN?

  What the DRS/HA in a cluster like this? DRS and HA is smart enough to understand that some a host does not have access to a certain LUN

  and choose another host, or would it fail?

  This question has a meaning?

  See you soon

  Hello

  The clarion should have no problem, but the MSA2000 may have some. I didn't a lot of research on this subject. The easiest way would be to add hosts to LUN until the SCSI reservation conflicts arise... This will give the upper limit.

• Number of hosts per rule Script

  Hello

  By following http://en.community.dell.com/techcenter/performance-monitoring/foglight-administrators/f/4788/t/19550391, we have a good wee script that returns the names of all the enabled rules that the scope is a certain crowd against.  The original script on this page has been changed, here's the actual script that we use:

  Don't forget to change the hostname down!

  //

  Initialize

  //

  def rs = server ["RuleService"]

  def QS = server ["QueryService"]

  def rules = rs.getAllRules)

  def hosts = new TreeMap()

  Browse all rules

  //

  (rule of rules)

  {

  This will not work for the rules without a scope query, so

  Let's ignore them!

  //

  def query = rule.getScopingQuery)

  isRunning def = rule.isRunning)

  If (request == null | query == "" |! isRunning)

  continue

  Kickoff of the scope query and see what we get.

  Browse all topology objects

  and collect the monitored hosts.

  //

  def objs = qs.queryTopologyObjects (query)

  for (obj in objs)

  {

  host of def = obj ['monitoredHost']

  If we cannot find the monitored host, this rule

  probably does not apply to us

  //

  if(Host == null)

  continue

  Create a new location for this host if necessary

  //

  def hostName = host ["name"]

  def hostRules = host [hostname]

  if(hostRules == null)

  {

  hostRules = [] like TreeSet

  host [hostname] = hostRules

  }

  Add the rule to the host

  //

  hostRules.add (rule.getName ())

  }

  }

  Print pretty

  //

  guests return ["your - client.here.com'"]

  Example of output would be:

  [CPU use, system files, use memory capacity]

  This script can be edited (or a written new) for a particular rule, it will return a list of all the hosts extended?  I guess it's pretty simple for geniuses here.

  Thank you

  Hi Brian...

  I have an iteration over for you. This gets all the rules and runs

  application of determination of the scope of each rule. It takes each result of said and tries to find any host (s) Hung

  out some likely properties of the result (see the getRelatedHostName() method). You can

  grep through the results for the rules you are interested in.

  Enjoy!

• MAX hosts per Pool of resources?

  Hello

  Looking ate Lele Maximums of Configuration doc for vSphere4 Update1, I can't find information like the number MAX of ESXi hosts perresource pool.

  Ask because we just added 8 ESXi hosts in the default pool and our broker began broadcasting the following error message:

  Event type: WARNING

  Event source: VMware View

  Event category: VMware View

  Event ID: 104

  Date: 12/07/2010

  Time: 15:10:25

  User: NT AUTHORITY\SYSTEM

  Computer: CDEVBROKER01

  Description:

  Pool cn = 3cf943ec-9879-45dc-92b5-c8fbe919b1c8, OU = virtualcenter, OU = propriΘtΘs, dc = vdi, dc is vmware, dc = int::Unable to create the new VM - VMware.Sim.Fault.TooManyHostsInComputeResourceFault: pool of resources me = resgroup-152, cluster me = field-c7, numHosts = 15, maxHosts = 8

  Then within the administration Web page VIEW data warehouses were more visible, non of them!  We then removed the new 8 hosts and now everything is fine. So my question is:

  Is this a limitation of resource pool or the host of MAX 8 for the limitation of the view?

  The limitation is around composer, and you can have a maximum of 8 hosts per cluster

• See the number of paths per LUN by host

  Hello

  I saw so many scripts these days on how to check my connections of storage, but I still don't get the info for that I'm looking. I'd like to see for each host for each LUN (RDM / Datastore) the number of paths. I found scripts that show me the active paths, paths of deaths and work, but none of them helps me to see the number of paths for each host.

  The following Luke good script seems to be a good starting point, but again once it shows total by hba, that I need for each host per lun.

  $esx = get-VMHost vcdvm580.virtualcenter.lan

  foreach ($hba to (VMHostHba Get - VMHost $esx - type "FibreChannel")) {}

  $target = ((get - see $hba. VMhost). Config.StorageDevice.ScsiTopology.Adapter | where {$_.} Adapter - eq $hba. Key}). Goal

  $luns = get-ScsiLun - Hba $hba - LunType 'disk '.

  $nrPaths = ($target | % {$_.}) Lun.Count} | Measure - Object - sum). Sum

  Write-Host $hba. Device ' target: ' $target. County "devices:" $luns. County ' path: ' $nrPaths

  }

  Any help would be appreciated.

  Gabrié

  You mean something like this?

  $esxName = "MyEsx".

  $esx = get-VMHost-name $esxName

  $esxcli = get-EsxCli - VMHost $esxName

  $hba = get-VMHostHba - VMHost $esx - type FibreChannel | Select the name of ExpandProperty-

• Limit the maximum number of characters per line in the TextField, help please

  Hello Livecycle designers!

  It would be great if you could help me with the following problem. I have a TextField with 5 lines (limit of the viewable area and the exact height) and I want to limit the maximum number of characters per line up to 10 (as well as the total in this field at 50, but I'm able to do with the option "time limit, max characters").

  As far as I know can be done only by the script so if you change that I wrote:

  lines of the var = xfa.event.newText.toString().split('\n');

  i = Lines.Length,
  maxChar = "10";

  If {(maxChar)
  While (I--> 0) {}
  If (rows [i] .length == maxChar) {}
  XFA. Event.change = "\n";
  }
  }
  }

  and actually who works very well when instead of '\n' in the 1st line, I put any character (e.g. ' |' and I won't pretend that ' |' is my new \n).

  So the main problem is to split the text entered by the user in lines (the '\n' is unfortunately not working). So the solution to this problem would somehow split my Textbox in lines (in table) after the user presses ENTER.

  I'd appreciate any help here, so if you have just 2 minutes of your time, please help me.

  Hello

  I have rebuild your idea... that is the result.

  var Input = xfa.event.fullText;

  var FullLength = Input.length;

  var SplitLength = 10

  var SplitParts = Math.ceil(FullLength / SplitLength)

  var JoinString = "";

   

  for (var i = 0; i)<= splitparts;="">

  {

  SplitString = Input.substring (0, SplitLength);

  Entry = Input.replace (SplitString, "");

  JoinString = JoinString + SplitString + "\u000a";

  }

  xfa.resolveNode("Textfield2").rawValue = JoinString;

• Limit the number of lines per group

  Hi guys,.
  
  I would use a query that returns only n number of lines per group and always show all columns in a table.
  
  For example:
  
  We have a table_customer, I would like to get a 100 records per dealer in a sql
  
  
  What would be the best way to do this? This isn't really my question saves back them, the top 100 or random, etc.
  
  Thanks in advance

  Hi and welcome to the forum!

  You can use the ROW_NUMBER() analytic function with a subquery to get the results you need. For example the following pseudocode (given that I have no definitions or column names) could be modified to work for your case

  SELECT     *
  FROM
  (
       SELECT     TABLE_CUSTOMER.*
       ,     ROW_NUMBER() OVER (PARTITION BY  ORDER BY

• Maximum number of hosts mapped to a single LUN ESX

  I have a TB 1.9 LUN presented to an IBM SVC to several groups of ESX/ESXi include versions 3.5 (ESX), 4.1 (ESXi) and 5.0 (ESXi).  I read 3.5 has a host LUN '' recommended '' limit 32.

  I'm looking for more details on this issue.  This applies only the number of 3.5 hosts who can see the data store or all combined ESX hosts.  And why is it recommended to vs a strict limit?  We are trying to implement a logic unit number mapped to ESX host clusters as possible in order to support a mass migration to a new environment.

  I'm pretty new to VMWare world so please excuse me if I'm not clear on what I ask, or do not include any other relevant information.

  I don't think it's a contradiction at all.

  It is said that a given host can have up to 256 LUNS.  A volume given (VMFS) are accessible by up to 64 hosts.

  They are 2 completely different scenarios.

• Script to gather and calculate the total number og Sockets PR. cluster

  Hello

  for licensing purposes, I need to collect a report host information and decision-making by the host.

  I want the report to include the following text:
  -Display the host by cluster (attached script) information.

  -A title with NOMCLUSTER by cluster

  -The total catch by cluster

  I guess my problem is that I work in a table and I want to insert empty lines and headlines and my attempts have failed so far. I don't know if I should convert to html format and change the page in this way. (hope not)

  I'd appreciate any help...

• Get number of VM by Cluster

  I have one line that I found but you want to convert to a format that I can export to CSV.  So, how to do this:

  $Clusters = get-Cluster

  foreach ($Cluster in $Clusters) {$VMHosts = Get-Cluster $Cluster |} Get-VMHost; $VMs = get-Cluster $Cluster | Get - VM; $Cluster.Name.ToUpper (); {$VMs.count}

  and convert them into something like this:

  $TDate = get-Date - uformat "%m %Y %d."

  $File = "DataStore_Report_by_Cluster_" + $TDate + ".csv".

  1. Check if the file exists

  If (Test-Path $File)

• ASA 5505 host under license limit has been exceeded

  I'm receive syslog message 450001 - host license limit has been exceeded.

  To see the version on my ASA 5505 (8.0.2), inside hosts are limited to 10. The limit of 10 corresponds to the limit (10) syslog error message.

  How is this calculated number of hosts? Show arp represents 6 addresses glued to the inside interface.

  Hello

  Don't use "show arp", use "local host" instead.

  Excerpt from http://www.cisco.com/en/US/docs/security/asa/asa72/configuration/guide/specs.pdf

  In routed mode, hosts inside (business and home VLAN) account in the limit only when communicating with the outside (Internet, VLAN).

  Internet hosts are not counted toward the limit. Also, guests who initiates the traffic between businesses and home are not counted toward the limit. The interface

  partner with the value default route is considered to be the Internet interface. If there is no default route, hosts on all interfaces are taken into account in the limit.

  In transparent mode, the interface with the smallest number of hosts is counted within the limits of the host. See the show local-host command to view the host

  limits.

• PowerCLI - get the number of cores per processor and number of Sockets

  Greetings,

  We are responsible to give a list of all our virtual machines with their host name, the number of CPUs, the BONES and the number of cores per processor for verification.

  I immediately said that this would not be a problem with PowerCLI. However I seem to have more trouble with it than expected.

  Get the number of CPUS is not a problem, but the time wherever I want to divide the number of cores and the number of sockets, it seems to hit a dead end.

  I found the following entries of the community concerned:

  Re: vSphere 5. Casings of vCPU and cores per CPU (PowerCLI) bug

  Machine virtual access avancΘs | VMware vSphere Blog - VMware Blogs

  Parameters to retrieve and set Advanced Configuration (VMX) VM

  But neither seemed to give me the right input. The advanced configuration settings do not appear to contain the number of cores/sockets and Get-View and Get - VM normal controls do not seem to differentiate between carrots and the power outlets and just give the number of processors.

  Because we need these settings for a check I doubt I'm the first to need this information. Does anyone have an idea how to get this information?

  Please note that it is the number of cores and casings of a VM, not an ESXi host.

  Thanks in advance,
