Increase Datastore

[malabelle]

Hi,

is there a way to increase a datastore by powercli?

I tried with vcli and it gives me that

C:\Program Files (x86)\VMware\VMware vSphere CLI\bin>vmkfstools.pl --growfs /vmfs/devices/naa.600507630affc1f30000000000000040:1 --server esx1.domain.local --username root --password "blablabla"

Unknown option: growfs

For a summary of command usage, type 'C:\Program Files (x86)\VMware\VMware vSphere CLI\bin\vmkfstools.pl --help'.

For documentation, type 'perldoc C:\Program Files (x86)\VMware\VMware vSphere CLI\bin\vmkfstools.pl'.

Afaik there is no PowerCLI cmdlet to extend a datastore.

You can do it by using the vSphere API from PowerCLI, but it is a rather complex process.

How to use the vmkfstools.pl script is documented in KB1009125

Thanks. I had read it, but it doesn't work when I try the last command.

What I don't understand, since the "Increase" option is a GUI button, it odd it is not scriptable by powercli, don't you think?

[LucD]

You can do this in a PowerCLI script but it will require the use of some SDK API.

Have a look with Onyx what goes on behind the scene when you click the Increase button.

Ok, thanks, good Idea, I did'nt think about Onyx

here it is.
