Just for history: arcconf must be taken from CIM package, not from ASM !
It can be run in ANY pc/vm on the network. To get an access to adaptec controller via ESXi, you must execute command initially:
arcconf.exe setvmcredential <ip_address_of_HV_with_Adaptec_drivers> 5989 <user> <password>
File VMCIMOMConfig.txt will be created with hash-credentials, this file is used when you start arcconf.
Tested with Adaptec 2405, 2805 and windows arcconf client.
