Host sets total exported size seems small
On the Host Sets screen, the expanded list pane view includes columns for Volumes Exported to Member Hosts, Volumes Exported to Host Set, and Total Exported Size. In some cases, the total exported size might seem too small (or show as zero) relative to the number of exported virtual volumes that are listed.
The total exported size sums the size of the virtual volumes that are exported to the host set. The total does not sum the size of the virtual volumes that are exported to individual hosts in the host set.
This issue is known behavior. No action is required.
