ESX recognize partial VMFS

[dingding]

3 ESX 4.1 connect to one Dell EqualLogic PS6100X, from storage, mapping 6 LUNs to all ESX, all ESX can see the LUNs, but only ESX1 can see all VMFS, ESX2 can see only 3 VMFS, and ESX3 can see only 1  VMFS, any suggestion? thanks in advance!

By default Equallogic volumes are "single-host-connections".

You must flag the multiple host option on each volume.
