Command View EVA: "No storage systems are visible to this management server"

Command View EVA: "No storage systems are visible to this management server"

Our configuration:
- Host: Windows Server 2008 R2; Emulex HBA LP9802; Emulex OneCommand installed; EVA Command View 9.2 installed
- FC Switch: HP 2/16
- Controller: 2x HSV110
- Storages: 2xM5214 with 2 FC I/Os

Situation:
- FC is running; FC name service shows both controllers and HBA
- controller installed with same WWN and checksum, no password
- Zoning is configured
- Storages connected to HSV controllers (storage 1 to controller 1, storage 2 to controller 2; no redundancy)

Problem:
- Emulex OneCommand shows link down to the fabric even the HBA LEDs and the FC switch shows online status with 2G
- Command View EVA shows "No storage systems are visible to this management server" after discovery

Re: Command View EVA: "No storage systems are visible to this management server"

Did you check if the switch see both, array and server and the EVA can see the server?

Hope this helps!
Regards
Torsten.

Re: Command View EVA: "No storage systems are visible to this management server"

Thank You for fast response.

The switch can see the controllers with the unique WWN and the HBA in the server (checked with Web interface).

From server side the Emulex OneCommander shows me a "Link Down" of the HBA (I can't understand it) but connected to this the (unique) port WWN of the controllers.

What do You mean with "and the EVA can see the server". I don't know any other possible diagnosis then from FC switch und FC HBA side.

Re: Command View EVA: "No storage systems are visible to this management server"

When you configure the hosts on EVA you should see the WWN of the CV server too.

Hope this helps!

Re: Command View EVA: "No storage systems are visible to this management server"

When you configure the hosts on EVA you should see the WWN of the CV server too.

I went through the EVA installation guide and though there is a single point of configuration for the arrays in the CV. This starts with the dicovery (and fails). Is there an additional configuration point ("configure the hosts on EVA ...")?

Try setting the HBA's to be forced to 2GB instead of Auto. Also, make sure the HBA is set to Point-to-point fabric. Make sure you have the Storport drivers installed as well as the MPIO/DSM drivers. These drivers can be downloaded at:

Storport: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12169&prodSeriesId=3185350&swItem=co-83126-1&prodNameId=1833540&swEnvOID=4064&swLang=8&taskId=135&mode=3
MPIO/DSM: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12169&prodSeriesId=421492&prodNameId=421494&swEnvOID=4064&swLang=13&mode=2&taskId=135&swItem=co-84060-1

Re: Command View EVA: "No storage systems are visible to this management server"

I've changed the port settings on FC switch and HBA side to 2G.

I've changed the HBA driver parameter Topology to F_Port Fabric.

The StorPort driver from Emulex was installed (the driver from HP could not be installed: message during installation regarding the an already installed driver).
I've installed the MPIO/ DSM driver from HP and restarted the host system.
At the end without success. Still no storage ressources visible in the Command View EVA.

Re: Command View EVA: "No storage systems are visible to this management server"

Hi!

You can try to run the command "cvutil paths" from the command view directory. That should show you if the server can see the storage.
If it can't see any storage devices then yes, your server cannot see the EVA over fc.
You can also check device manager and in there if it's working you should see "HSV controller devices".

What do you mean with "- Storages connected to HSV controllers (storage 1 to controller 1, storage 2 to controller 2; no redundancy)"?

How is your zoning configured?
Do you have a zone for the CV server and both controllers? Has it been enabled?

Has this ever worked?
Do you have any other fc targets that the server could view over the SAN?
Do you have any other servers or HBAs?

Re: Command View EVA: "No storage systems are visible to this management server"

cvutil paths and cvuti luns give no information back (only new line).

The device manager of the CV server doesn't show any "HSV controller devices".

The storages (I/O A and B) are connected to the DP ports of the HSV controllers (1A, 1B); no cross connection; no redundancy.

I've 1 zone configured and enabled (checked by telnet to the FC switch) for the ports 0-4. The CV server and the HSV controllers are connected to ports 0, 1, 2.

This is a complete new and standalone installation. There are no other devices or hosts connected to the FC.

You need to connect your SAN to the FP ports.
The DP ports are where you connect the disk enclosures.

With storages - do you mean the disk enclosures?

How are the FP ports connected? To your SAN?

Re: Command View EVA: "No storage systems are visible to this management server"

The HSV controllers are connected to the FC switch via the FP parts.

The disc enclosures are connected via the A and B I/O modules to the DP ports (1A, 1B) of the HSV controllers.

Starting the HSV controllers the disks in the enclosures are reacting in phase "discovering disk" of the controller.

The FC switch can see the HSV controllers and the HBA (checked with Web interface).

So for me the communication from disk enclosures to HSV controllers to FC switch looks o.k.

The problem is the HBA in the CV server and the connectivity to the FC switch.

I'm thinking about deinstallation of the OneCommand tool and StorPort driver from Emulex replacing it with the StorPort driver from HP.

Re: Command View EVA: "No storage systems are visible to this management server"

You should not be using the Storport driver from Emulex. You SHOULD be using the storport driver from HP. Does your FC switch show the port as being logged into the fabric?

Re: Command View EVA: "No storage systems are visible to this management server"

I`ve already deinstalled the Emulex software components and tried to install the HP driver. The HP install program terminates the installation due to an already installed driver of the same version.

"logged into the fabric": I can see the connected host in the FC name services and the port data, e.g. in the zone configuration wizard.
