vmware ESX

My first question about one problem , some time I have trying create
new virtual machine , the process work normally but when I start
virtual machine show me message - "Not have enough space for start
virtual machine" .

I don´t understand why this message ,because I use storage all virtual
machines are storaged on SAN then should have enough suficient for
start a virtual machine . I have delete old virtual machine for start
this new VM .

There is  any form for check space of local disk VMware ESX SErver ?

if you only got 320mb free space that will not be enough for swap files, logs.

check the datastore storage space.

select host server, configuration, storage, and check the datastore.

what size virtual machine disk have you created, and what size is the datastore?

When you start a virtualmachine vmware kernel assigns a space which is at most equal to the memory you allocate for it. But if you have completely filled your storage it can not create this temporary space and cannot start the virtual machine.

So you should make sure that not the full SAN LUN is fully allocated o the sytems. And don't forget that currently vmware allows LUNS of Up to 2TB in size. so if your LN is greater it can only address the first 2TB of the LUN.

To check the storage ckik on the host > See Hardware box and select Storage and choose the storage from datastores. Make sure that there's no Alert forr size and you have still some free space left. If not create another LUN and move your VM there.

Thank very much for replys  then I have checked that data store of Vm have features  49.99gb total space, 49,75 gb total formatted capacity and 320 mb free space. I belive  is enough for only start. Vm.  

the vmware storage some thing local on server. ? because the lun  has space enough.

With only 320Mb free space, your virtual machine will need to have less than 320Mb of memory as VMWare automatically creates space on the disk equal to the memory of the guest instance plus a small overhead. If you are desperate to get the machine started, try reducing the memory down to around 200Mb, or moving the machine (or virtual swap) onto a different data store
