SAN Switch discovery

[Andreas F.]

Hello,

I tried to integrate our new SAN switch (model HP StorageWorks 8/20q Fibre Channel Switch) within HPSIM. The switch is configured to use SNMP, CIM and SSH as management protocols.
If I start to discover the switch, I only got some few information about this device (like ip address, hardware description and system contact - typically SNMP information). The 'System Type' is set to 'Unknown'. HPSIM lists SNMP and SSH as used management protocols, but not wBEM (of course the logon information are the right one).

If I test the connection with wbemdisco, I got the following error message:

C:\Program Files\HP\Systems Insight Manager>wbemdisco 10.0.91.240 5989 root/switch admin ######
07.08.2009 12:04:27,03
WbemDisco 01.01.00
------------------
HOST = 10.0.91.240
PORT = 5989
NAMESP = root/switch
USER = admin
PASSWD = *****
Connect to 10.0.91.240 in namespace root/switch with SSL=true
*** Error connecting with SSL=true - Return is for CIMVERSION 2.3 (CIM_ERR_INVALID_PARAMETER) ***

If I understand this error message correctly, the switch respond with a XML answer in cim version 2.3 and wbemdisco (and HPSIM too?!) expect cim version 2.0, right? BTW the same happen if I use a non-SSL connection.

Now my question: Is there a way to discovery my switch by using wbem?

Thanks in advance

To use wbem you'll need to load the appropriate CIMOM software. But SNMP should be able to pull more info from the switch and should be able to identify it. On the switch SNMP needs to be configured to allow the HP SIM Server access on the correct community name.

Hi Rob,

thanks for your answer. The switch have a built-in CIMOM and providers - no additional software installation is necessary. If I use my CIM Explorer I got many switch related information. The CIM works fine, but I guess that HPSIM cannot handle the answer from the switch (see the error message from wbemdisco, maybe HPSIM uses the same algorithm).
HPSIM and the switch uses the same SNMP community - and HPSIM can read some information like the system contact (which are entered by myself).

OK - That's new stuff for me. What version of HPSIM?
Looks like you're assessment is right, so you may need to drop back to SNMP until HPSIM catches up.

I use (Win) version 5.3 SP1 with the latest update kit installed.
Meanwhile I have to use SNMP and set some basic information (like system type) manually... :-|
