no one? so, i guess i'm a little bit f****. Any ideas?
have you done a Rescan of your datastores in the Configuration -> Storage tab? If that did not help, the vCenter converter should be free of charges - try downloading it here https://my.vmware.com/group/vmware/evalcenter?p=converter , or you can find it on some other software package hubs like softpedia.
yes, with converter sounds good but as I said - I don't have enough free spaces there because currently the VM is using around 850 GB space and I have free only 100 GB (if i delete one of the other VMs). I think the problem is with the CID of the HDD. I was thinking to change them but this leads to the question: what is the right way to do it. Actually I've made similar test on another esx and the solution from the links above worked just perfectly.
