On the storage page, the Disks page should include an option that triggers an Update-HostStorageCache on the on the machine being managed. Simply clicking the refresh circular arrow never does this.
This is important if Honolulu is being used along side the vSphere management tools to enlarge disks. Without the Update-HostStorageCache, you can never see the new space, and thus can't resize the volume for your customer.
Also needing the storage rescan. Further, when you go to actually extend/resize volume, it would be nice for an option to choose all available space on the disk the same as disk management. When I typed the exact value shown in maximum size, it still left 14 MB unallocated as per disk management.
Yes. Came to say the same. Surely there are more than two people running into this issue...
