snapdrive issues with 2003 servers and esxi 5.5

“vmdk is larger than the maximum size supported by datastore”

[SnapDrive Error]: Please specify valid VMFS datastore name. (SnapDrive Error Code: 0xc0041033)

 

Have a read of this:

http://support.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=600206

Create a new vmfs5 datastore and then add the key listed in the article. No need to restart snapdrive. snapdrive will then use that as the file to back the RDM when it does a verification.

Snapdrive Underlying connection was closed VCenter 5 / 5.5

It seems that a 2003 server doesn’t support the new SSL options that are enabled in the VC with 5.5 (and maybe earlier).

Try changing the following (taken from the release notes, which you’ve already read? 😉 :

  • On the vCenter Server host machine, reduce the implied security by allowing the server to communicate using weak cipher suites. To do this, include the following section in the vCenter Server vpxd.cfg file, located c:\Programdata\VMware\VMware VirtualCenter:
    <config>
    ...
    <vmacore>
    ...
    <ssl>
    ...
    <cipherList>ALL</cipherList>
    ...
    </ssl>
    ...
    </vmacore>
    ...
    </config>

restart the vcenter service and it should now hopefully work.

Vcenter 4 Windows 8 Hangs / Disappears

Having trouble installing Vcenter? If you look in %temp% the log file will give a clue, but it’s not obviosu to look there. Anyway, you need to install dot net 3.5 from the Add Features. You may get an error if you can’t get on to the internet, in that case, stick your CD in and run

Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs/LimitAccess

 

Or change /source to point to some network location that has an extract of the cd. Should work then!

Powersehll netapp volume resize

This script will resize any volumes on your controller that are more full than 96% and add an extra 5% on to them. You  can filter the list a little more if needed, for example I don’t attempt to resize any of our volumes that have the word “dr” in as they are snapmirror destinations.

 

 

$controllers = @(“controller1″,”controller2″)
$body=””
$resize=””
$emailto=”fillThisIn”
$emailfrom = “fillThisIn”
$emailsmtp = fillThisIn”
$emailsubject= “Drives resized”

foreach ($controller in $controllers){
connect-nacontroller $controller
$resize+= (Get-NaVol | where-object {$_.used -gt 96 } | ft -HideTableHeaders)
}

if ($resize -ne “”) {
foreach ($navol in $resize){
write-host “$navol”
Set-NaVolSize $navol +5%
$newsize = Get-NaVolSize $navol.SizeTotal
Set-NaVolAutosize $navol -Enabled
Set-NaVolAutosize $navol -MaximumSize +10%
$body += “Volume $navol on $controller script resized to $newsize and autogrow enabled `n”
}
$body += “check snapmirror destinations size for volumes above!”
send-mailmessage -to $emailto -from $emailfrom -smtpserver $emailsmtp -subject $emailsubject -body $body
}

 

Force Nexus Android Update

Want to force your Nexus to update to the latest version of Android, yet when you check it constantly say you have it? One way to do this is to wait… the other is to go to Settings>Apps>All. Find “Google services framework”. Force stop it then clear the data. After that got to the check for updates page. It should say last checked in 1970. Check for updates again and hopefully it will be there. I had to do this about 5 times before it worked, so you may have to too
