Solved: Get-datastore shows every datastore twice

TylerDurden77 · ‎01-14-2013

Hi Admins,

I trying to move VMs to another datastore using powershell.

move-vm servername -datastore iSCSI-vmfs04

Error message : Move-VM The specified parameter 'Datastore' expects a single value, but your name criteria 'iscsi-vmfs04' corresponds to multiple
values.

If i run get-datastores it will return:

iscsi-vmfs04

iscsi-vmfs05

iscsi-vmfs06

Is my pathpolicy the problem? using RoundRobin.

Storage vmotion works just fine if i use the vCenter GUI.

Advice?

Cheers,

tyler

You did notice that the free space is not exactly the same for both lines of the same datastore.

Do you have some ghost datastores in your vCenter perhaps ?

Could it be that you are running in "multiple" mode and that you have more than 1 open connection ?

Do a

Get-PowerCLIConfiguration

and

$defaultviservers

Hi LucD,

Thanks for ur reply.

Guess you are right.

S C:\> Get-PowerCLIConfiguration

Proxy Policy    Default Server Invalid Certificate
                Mode            Action
------------    --------------- --------------------
UseSystemProxy Multiple        Unset

PS C:\> $defaultviservers

----                           ---- ----
bman-vcenter02.domain.local   443   domain\user

But how can this be changed?

I try:

PS C:\> set-PowerCLIConfiguration -defaultviservermode Single

Proxy Policy    Default Server Invalid Certificate
                Mode            Action
------------    --------------- --------------------

The Set-PowerCLIConfiguration cmdlet has 3 scopes (Scope parameter).

If you want to change it for the current session, you do

Set-PowerCLIConfiguration -defaultviservermode Single -Scope Session

But I find it strange that you only see 1 connection in $defaultviservers.

Let's first set the config to single and then do the Get-Datastore again to see if it changed the result.

Update: which PowerCLI build are you using ? Do a

Get-PowerCLIVersion

The Scope parameter was introduced in the lastest version (5.1).

But it should change the setting in PowerCLI 5.0.1 with

Set-PowerCLIConfiguration -DefaultVIServerMode Single

as you did.

Strange, can you try to stop/start your the PowerCLI prompt/session ? And then check the setting again ?

And it would of course be better to upgrade to 5.1

LucD · ‎01-14-2013

How many ESXi servers do you have in that vCenter ?

Are they in a cluster ?

If not, can each see all the datastores ?

If yes, try doing

Get-Datastore -VMHost ESX1

You need to update the ESXi name of course

Blog: lucd.info Twitter: @LucD22 Co-author PowerCLI Reference

TylerDurden77 · ‎01-14-2013

Hi LucD,

I have 5 ESX hosts in one cluster. (5.1)

All 5 hosts can see the all datastores.

get-vmhost esx | get-datastore

This is the output id like to get...Thats strange..... or?

TylerDurden77 · ‎01-14-2013

This worked

$vm = get-vmhost esxhost | get-vm vmname
$dest = get-vmhost esxhost | Get-Datastore iscsi-vmfs04
Move-VM $vm -Datastore $dest

Very strange..

Regards,

Tyler

What does the following produce ?

foreach($ds in Get-Datastore){
  Get-View ($ds.ExtensionData.Host | %{$_.Key}) |
  select @{N="Datastore";E={$ds.Name}},
  @{N="Host";E={$_.Name}}
}

You should see a line for each ESXi that sees the datastore.

You did notice that the free space is not exactly the same for both lines of the same datastore.

Do you have some ghost datastores in your vCenter perhaps ?

Hi LucD,

Now i am a little bit ashamed....

The thing is that i just realized that we have 2 datacenters. (Understood this when you pointed out the difference"free space" on the datastores)

get-datacenter bman | get-datastore gives me the correct answers.

Thanks again for all ur help!

Regards,

Tyler
