On your 3020 did you expand one of the volumes? Once you do this the space will be available on the ESX side. A. expand a Volume in SC3020 ()not too large as you cannot shrink a volume) B. Expand the VMDK or RDM in ESX. Refer to page 55 of the Storage SC Series Best Practices with VMware vSphere 5.x–6.x: [URL]  
Hello, i addet more space to my storage and wanted to add this to my ESXI datastore. I cant't see space after the existing volume on esxi side - the svc3020 storage supports auto growing - what am I missing? Is theare any way to extend the existing vmfs beyond its limits?
