Managed Systems Configuration Guide
Chapter 16: Enterprise Virtual Array Configuration
To qualify as a valid SMS, the server must have Command View EVA installed (Version 7.0.1 or later) and
be managing at least one array. SMI-S is delivered with the Command View EVA installation and is
required as it serves as the communication path between HP SIM and the array, using a CIMOM for
WBEM communications.
Note: Event data for the EVA is only delivered to the Command View EVA that is actively managing
the array. However, you should also install ELMC on any server that is running Command View EVA
that is capable of being an active manager of an array of EVA devices. Any Command View EVA
instance that is not currently actively managing an EVA is called a passive instance of Command
View EVA.
SMS System and Access Requirements
Storage Management Server (SMS) requires a Microsoft Windows account with the correct group
privileges required to access Command View EVA.
Installing Command View EVA adds two new group privileges to a system: HP Storage Admins (write
access) and HP Storage Users (read access).
WEBES – EVA Communication
WEBES on the CMS requires credentials for an account with a minimum of read access. This username
and password are entered in the WEBES Managed Entity page for the SMS. This allows WEBES to
communicate with the array. See "Command View EVA Password Configuration" on page 119 for more
information about this process.
HP SIM – EVA Communication
SMI-S allows for WBEM protocol communication between HP SIM and the EVA array. SMI-S delivered
with Command View EVA versions prior to V8.0 uses a CIMOM that has independent user credentials
defined to allow for this WBEM communication path. Starting with Command View EVA 8.0 and later,
SMI-S has a certificate trust established and uses the Command View EVA credentials (as described in
"SMS System and Access Requirements" above).
Prior to Command View EVA 8.0, the installation of Command View EVA creates cimuser credentials for
an account on the SMS with a username of administrator and a password of administrator. The success of
the automatic creation of this cimuser identity is dependent on the pre-existence of the Windows
administrator account on the SMS that has a minimum privilege level of read access (for example, HP
Storage Users as described in "SMS System and Access Requirements" above).
Important: HP SIM requires this set of user credentials to be entered in the System Protocol Settings
page (see "Settings in HP SIM for WEBES" on page 120) for the SMS CIMOM to pass the WBEM
communication with the EVA.
In Command View EVA 8.x this has changed. There is no longer a separate username/password for
SMI-S. There is a Single Sign On (SSO) design using a trust relationship between Command View
EVA and SMI-S. The Command View EVA username and password are used for the SMI-S
connection.
