rebalance in vsan 5.5

Hi all,

We have vCenter 5.5 2442329 and ESXi 5.5 2638301

How can we do rebalance action for vsan 5.5 ?

vCenter 5.5 U2 does not have rebalance action in their command.

vCenter 6.0 have the command, but when trying to excute "vsan.proactive_rebalance -s 0", error message says that this command only works for host version 6.0 and above.

Need advice on these issues.
