New groups of DRS and rules, would avoid vMotion Storm
DRS groups and rules below look good to present our cluster that has never had one?
Our current cluster of business (20 hosts running ESXi 5.5U2) does not have rules of DRS in place. I'd like to introduce five new nodes in this cluster, but I don't want (fully automated) DRS to move our critical production VMs to these five nodes until they are sufficiently burned in. We want only our critical VMs not filing migrate to these new nodes for the moment.
DRS Group Manager
- Create two 'DRS Host groups':
- the VM guests
- new guest VM
- Create two 'DRS VM groups':
- production critical VMs
- VMs critics off-production
Here are the screenshots of the DRS rules that I've not enabled yet. DRS will attempt to overhaul all of the critical production VMs (1000 VMs) on these existing hosts or will he see that they already exist on these hosts and left alone? It will be graciously vMotion 100 critical VMs off-production for the new guests I bring in this cluster? I would like to avoid creating chaos by making the production of 1000 reviews VMs dragging around the existing VM guests.
With these two rules configured as 'must' of the rules, and all virtual machines running on the 'existing VM hosts', I expect that DRS will start the migration of the 'non-production critical VMs' as soon as rules are enabled. What do I usually when DRS rules configuration is to temporarily put the DRS on "Manual", set / add the rules and then go to the DRS tab see small jets DRS recommend after pressing the button "execute DRS. If the recommendations of the DRS me correspond to the expectations, I then the DRS automatic value again and let her work with DRS.

Hi guys,.
I need to refresh my mind.
I need to create rules of the DRS to keep the virtual machines running on a specific hosts bunch, and that's fine.
What about the HA? the DRS procedure rules will be kept in the case of a virtual machine will reboot due to HA?
I remember that reboot because HA DRS rules are always checked before placing a virtual computer on a specific host, but I need to have this confirmed.
Many thanks in advance,
Daniele
Hi Daniele,
I wrote a few articles on this topic, you can check:
http://frankdenneman.nl/2012/02/SDRS-anti-affinity-rule-types-and-HA-interoperability/
http://frankdenneman.nl/2010/12/VM-host-affinity-rules-should-or-must/
In short, HA is aware of the required rules, (designated with Must (not) run away). HA does not know if the rules.
And after the failover, the first time DRS HA is called (within 5 minutes) DRS violation of rules will correct them before the imbalance of the renderfarm.
Kind regards

Scipt PowerCli to find VM outside groups of DRS in VMware clusters configuration rules
Hello
I have a cluster VMware DRS rules enabled, with 'Virtual Machines to hosts' type.
Whenever a virtual machine is created, it must be added manually in one of our group of DRS within the parameters of the VMware cluster rules. To check if this action has not been forgotten, we need run a script with PowerCli, showing the virtual machine that are not present in the Group of DRS.
any idea to create this kind of script?
Thanks for your help
ConcerningWould this be something like this work?
$cluster = get-Cluster-name mycluster
$vmsInGroup = $cluster. ExtensionData.ConfigurationEx.Group | Where {$_-is [VMware.Vim.ClusterVmGroup]} | %{
Notice-EEG-Id $_. VM | Select the name of ExpandProperty-
}
Get-VM-location $cluster | Where {$vmsInGroup - notcontains $_.} Name} |
Select the name of ExpandProperty-
The script first gets the names of all virtual machines that are used in any VM Group on the cluster.
Then he gets all the virtual machines in the cluster and displays only the names of these virtual machines that are not in a VM group

I am trying this:
app.activeDocument.copy;
var newItem;
var docSelected = app.activeDocument.selection;
If (docSelected.length > 0) {}
Create a new document and move the items selected to her
var newDoc = app.documents.add ();
}
If (docSelected.length > 0) {}
for (i = 0; i < docSelected.length; i ++) {docSelected [i] .selected = false;}
newItem is docSelected [i] .duplicate (newDoc, ElementPlacement.PLACEATEND);.
}
}
docRef var = activeDocument
iCount = docRef.groupItems.length var
If (iCount > 0) {}
graphRef = {}
create an object for the step/repeat
for (var i = 0; i < iCount; i ++) {}
graphRef = docRef.groupItems [i]; graphRef.selected = true ;}
}
ensures the selection of all items that have been copied to the new page
OK here - but what then? no idea what the settings are.
but know those shown is false.
for loop() {}
graphRef.duplicate(0,stepac*);?
as many times as necessary
}
If it worked
next step would be to group the result
and copy it down in another loop .
as many times as necessary
var stepac is my defined distance to cross
... unless there is a better method to use
to get the same result.
Sorry if I badly copied something here, media, etc.
"Here's one I prepared earlier".
General information:
I have a label to the step and repeat program (NOT of Esko stepX) which
used to work fine in previous versions of CS but now regularly
CS6 crashes. Before that, I used to use actions, but need one for
Every drill that we have (about 2500). stepX was formerly offered to us for a great $ 4 figure.
So I decided to try to "roll my own" script to work with my own details tailor .csv files.
No JS experience before last week, but worked a
Basic procedure called Arcplus DOS program for
25 years... any assistance would be most welcome
Hi, Monika
I had seen that you had posted something on the subject of step and repeat before.
Frankly, I can do that in Illustrator standing on my head: it's part of my job and I
fact for years. The point is to automate to save time and effort and avoid mistakes.
I used actions and a plug-in purchased from a developer, but the plug-in is not
as functional under CS6 and tends to crash the program and you would need an action
for every cut we have - at least 2500. You can buy Esko stepX for a sum of four thick numbers
but I just less expensive than that - if I can do it, and I think I can by trials, errors and effort.
Thanks for your advice - I'm sorry, but it's not to the point.

Hi, I bought a new laptop and I would like to install Photoshop 5.5 Extended for the new laptop computer. Something to consider before you begin to install?
The reason is to avoid any inconvenience. What do I need to uninstall Photoshop beforehand?
Thanks for the tips
The mobile fact have separate start-up and data readers? If so and the boot drive has limited space, you may want to consider relocation of things like bridges on the data disk cache. I can't think another thing to consider from the start, however.

My child has its own Apple ID, throughout I would buy apps for her and she would transfer to his iPad. But since a new update she has no access to its power supplies that are on my shopping list. She is using "Video star" app?
Hi Breda49
iTunes purchases (free downloads are taken for granted) are permanently linked to the Apple that was used to buy ID.
To work around this problem, you can set up sharing of family and your child. This will allow you to share all your purchases.

On my old computer (XP), I used app fast backup protection to back up my files to an external drive, Iomega hosted Media Network Hard (2 TB). I have a new Dell PC with Windows 7 (64 bit) OS. With the help of a cable I copied all the files from my XP to Windows 7 computer. All the files on the external hard drive, copied to a "network". I am able to view all the folders of the Iomega file, but I can't back up my files to protect fast has not been improved to work w/Win 7. Quick protect is divided into 6 different discs (photo-U, V-ActiveFolders, W-Music, X-backups, Public-Y, Z-movies), Iomega recommends using backup Windows and restore. "Before you start this process, I would like to know if Windows Backup and Restore will copy a new set of files and adding to what is there in the folder backup previous Player X or if it will start a"new"backup" folder on drive X.

Probably in a completely different format than you are accustomed to and accessible in a different way.
Although I suppose you could create separate jobs for each of the existing partitions, if you wish. But I would like to backup these partitions to something else before you start. Heh

I installed windows 7 on a mac with boot camp and then used parallels to create a virtual machine to run windows inside Mac os10.6. Now he says I need to activate windows again, but he said I need a new activation key. Any ideas would be appreciated
Yes, you must purchase a full license for the second installation of Windows 7 product key. 1 activation allows only one Windows 7 product key. Apparently, you now have a second facility that requires a second product key. Carey Frisch

Hello, I need help. in photoshop / editing / color / color / RGB management rules, it is impossible to change this point. Is in the "off" position and I would choose "preserve embedded profiles' I'm on windows 8 and creative cloud for photoshop.
Policies automatically goes to "off" If you have your screen as working RGB profile - what is something that you should never do. Always have a standard space like RGB work.
And Yes, "preserve embedded profiles" is the only sensitive parameter. Others are best for special purposes where you really know what you are doing - at worst they will transform your archive in a unrecoverable mess.

With previous versions, I could press control (mac) and click on a layer, and he would choose this graph, what form it was. Then I could go to image-culture and reframe the entire file down to that size. Now, this feature is missing. What is the new way to do this?
This is the command key, not the control key for a Mac that you use on the layer.
