Are you sure?  I.e., are you sure it isn't just a driver issue?  Do
you have the HP-specific distro for ESXi?  The one you get from VMware
won't have the right driver for that RAID controller, for sure.

The only way to use ZFS pools in any reasonable fashion with ESXi is
to present iSCSI targets to the ESXi server from the host that has the
pools.  Just my $0.02 ($0.11 adjusted for inflation).
