Install CIM provider 7.30 attached (downloaded from Adaptec web site) cim_vmware_v7_30_18837
esxcli software vib install -f -v file:/vmfs/volume/datastore1/filename.vib
Open ESXi firewall to CIM provider port
Create symbolic link on esxi
ln -s /dev/aac0 /dev/aac
I have not yet checked what happens on esxi reboot if link is lost (I think)
