VMware vSphere 5 is now Generally Available

August 25th, 2011 No comments

 

Some big news – the recently announced vSphere 5 is now generally available for download. I have been waiting with baited breath for this and will be giving it a try in my home lab soon. It may be a while yet until the company I work for moves in for the upgrade, so hopefully in the meantime I will be able to learn a fair amount for when the upgrade process does begin.

 

You can grab vSphere 5 from the VMware site here.

 

Are you running vSphere 5 already? How has your testing been? Has anybody upgraded from a previous version of ESX or ESXi? Drop your feedback in the comments section to discuss!

PowerCLI – Automate adding NFS Datastores to a cluster of ESX or ESXi hosts

August 21st, 2011 No comments

 

The other day I needed to add three NFS datastores to a bunch vSphere ESX hosts in a specific cluster. Rather than go through each host in vCenter individually, adding the datastore using the Add Storage wizard, I thought I would script the process in PowerCLI and get it done in a more automated fashion. Using PowerCLI automation, this helped me save some time. I had about 7 ESX hosts to add the Datastores to, so doing this manually would have taken twice the time it took me to whip up this script and run it. Plus, this can be used in the future for other Datastores or other clusters by simply modifying the script and re-running it.

 

Here is the script:

 

# PowerCLI script to add NFS datastores to ESX/ESXi hosts in a specified Cluster
# Only does this to hosts marked as "Connected"
$hostsincluster = Get-Cluster "Cluster 1 - M" | Get-VMHost -State "Connected"
ForEach ($vmhost in $hostsincluster)
{
    ""
    "Adding NFS Datastores to ESX host: $vmhost"
    "-----------------"
    "1st - MER001 - NAS-SATA-RAID6 (Veeam Backups)"
    New-Datastore -VMHost $vmhost -Name "MER001 - NAS-SATA-RAID6 (Veeam Backups)" -Nfs -NfsHost 10.1.35.1 -Path /share/VeeamBackup01
    "2nd - MER002 - NAS-SATA-RAID6 (ISOs)"
    New-Datastore -VMHost $vmhost -Name "MER002 - NAS-SATA-RAID6 (ISOs)" -Nfs -NfsHost 10.1.35.1 -Path /share/Images01
    "3rd - MER003 - NAS-SATA-RAID6 (XenStore01)"
    New-Datastore -VMHost $vmhost -Name "MER003 - NAS-SATA-RAID6 (XenStore01)" -Nfs -NfsHost 10.1.35.1 -Path /share/XenStore01
}
"All Done. Check to ensure no errors were reported above."

 

So the script above looks for ESX or ESXi hosts in a specified cluster that are in a “Connected” state – i.e. they are not disconnected in vCenter (we wouldn’t want to try add Datastores to hosts that don’t exist!). So we use the Get-Cluster cmdlet to say we are only concerned with hosts in this particular cluster (specified by the “Cluster 1 – M” name in my case. Obviously change this to the name of your cluster you will be working with.) We then use Get-VMHost -State “Connected” to list all of the hosts in this cluster that are in a connected state. In my example I had 2 x ESX hosts that were in a disconnected state, and I didn’t want to include these, so this part worked nicely. This list of hosts in then assigned to the $hostsincluster variable. We then use the ForEach loop to iterate through each host in this list of hosts and do the bit in-between the curly brackets for each host.

 

In my case you may notice that I am adding Datastores from the same NFS (NAS) server. They are just being mounted to different paths on the server and being given different names. I had three Datastores to add, so therefore use the New-Datastore cmlet three times for each host. You will need to adjust this to your needs – maybe you just need to add one datastore to each host, therefore remove the two extra New-Datastore cmdlet parts. Also remember to adjust the -NfsHost and -Path sections to suit your own environment.

 

We could improve on the above script by making it more customisable for future / others to use. Lets give that a quick go then and use variables to define everything at the top of the script. This means that the variables can be changed at the top of script without worrying too much about reading through the whole script to check for things to change. We’ll also add a Connect-VIServer cmdlet in there in case you have not already connected to your vCenter server and authenticated in your PowerCLI session that is running the script.

 

# PowerCLI script to add NFS datastores to ESX/ESXi hosts in a specified Cluster
# Only does this to hosts marked as "Connected"

# Define our settings
$vcserver = "vcenter01"
$clustername = "Cluster 1 - M"
$nfshost = "10.1.35.1"
$nfspath1 = "/share/VeeamBackup01"
$nfspath2 = "/share/Images01"
$nfspath3 = "/share/XenStore01"

# Connect to vCenter server
Connect-VIServer $vcserver

# Do the work
$hostsincluster = Get-Cluster $clustername | Get-VMHost -State "Connected"
ForEach ($vmhost in $hostsincluster)
{
    ""
    "Adding NFS Datastores to ESX host: $vmhost"
    "-----------------"
    "1st - MER001 - NAS-SATA-RAID6 (Veeam Backups)"
    New-Datastore -VMHost $vmhost -Name "MER001 - NAS-SATA-RAID6 (Veeam Backups)" -Nfs -NfsHost $nfshost -Path $nfspath1
    "2nd - MER002 - NAS-SATA-RAID6 (ISOs)"
    New-Datastore -VMHost $vmhost -Name "MER002 - NAS-SATA-RAID6 (ISOs)" -Nfs -NfsHost $nfshost -Path $nfspath2
    "3rd - MER003 - NAS-SATA-RAID6 (XenStore01)"
    New-Datastore -VMHost $vmhost -Name "MER003 - NAS-SATA-RAID6 (XenStore01)" -Nfs -NfsHost $nfshost -Path $nfspath3
}
"All Done. Check to ensure no errors were reported above."

So as you can see we have now defined the name of the cluster, our NAS/NFS server and three paths to different NFS shares at the top of the script, then just referenced these variables later on in the script. This means we can now easily adjust the defined variables at the top of our script in the future to work with different clusters, NAS/NFS servers or paths. The output of your final script when run should give you a nice view of what has happened too. It will output that it is adding NFS Datastores to each host it iterates through, and if it comes across any errors those should be marked in red as PowerShell / PowerCLI normally would do, allowing you to amend or update any details as necessary. PS, don’t forget to change the name of each Datastore in the script to something of your own choice (it is the part after the -Name parameter in each New-Datastore line).

 

Here is the download for the full script (with latest improvements):

Cosmosis (iOS) – updated to version 1.3

August 9th, 2011 No comments

So heres an update that is slightly off my usual subject matter! I have been spending a little bit of time updating my 2D Space shmup game I have developed for iOS (iPhone, iPod touch, iPad). I  finished submitting the update to Apple on 04/08/2011, and this morning I saw it has now been approved, so it is ready to be downloaded / updated from the App Store.

 

Bonus level 2 added in version 1.3

 

Here is a list of the most significant new features in version 1.3.

 

– Unlocked all levels by default
– New (Second) Bonus Level added
– New enemy ship type added
– New enemy ship attack patterns (more challenging/interesting)
– New scrolling level select screen
– Main menu redesigned and new ambient music added for menu and in game
– OpenFeint updated
– New News menu option added for the latest news and announcements
– Game difficulty tweaked to make it slightly more challenging
– Bosses are a bit to tougher to fight now
– Survival mode difficulty tweaked
– New loading & credits screen
– App rating dialog that appears after a few days now works

 

So there is some new content as well as better difficulty and more challenging enemies to fight. I also added an interesting new feature – the News screen. This integrates with OpenFeint and pulls down and news / announcements I make on my developer control panel for OpenFeint into this custom designed (Cosmosis themed) News screen. It also updates the App’s badge icon according to the number of new (unread) news announcements and displays a small badge icon on the news menu in game. The main reason I developed this extra bit, is that I would like to be able to notify users of any future new releases (apps) I may release.
