ProLiant 1600's and Serial Numbers

[Michael Jay_2]

I've got a handful of 1600's (running NT, 2K and 2K3) that have the correct SN in their BIOS and it shows up correctly in the survey but attempting to read their SNs using WMI returns blank and thus SIM is blank. Mgmt Agents are anywhere from 5.5 to 6.4.

Any ideas on what might be causing this or how to make sure SIM gets the correct info?

TIA.

The management agents don't use WMI. When you view the management agent, is the serial number visible?

How are you attempting to read the S/N's via WMI?
I've just run a standard Inventory report on my 3 remaining PL 1600's the S/N's are reported on.

I guess I'm a bit off in my original post. All the above 1600 SN's ARE reporting to SIM OK, but some (not all) of the 1600's DO NOT report their SN via WMI and this is the issue I was trying to resolve (sorry for any confusion).

Maybe this question would be more appropriate in a WMI type forum or group...

The vbs script I'm running (in part) is:

Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!//" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_Bios",,48)
For Each objItem in colItems
If IsNull(objItem.Version) Then
WScript.Echo strComputer
Else
Wscript.Echo strComputer & vbtab & objItem.SerialNumber
End If

There were 2 major versions of the 1600, one with the ROM type of E34 and the other of P08. I don't recall which is the older of the two. Even though both are 1600s, they are different generations. These days we would differentiate them as G1 and G2, but that's the old days. My guess is that you're getting the information through WMI on the G2 servers and not the G1. The serial number field in WMI is populated from SMBIOS. I don't remember the exact dates, but it's possible that the older model pre-dates the SMBIOS spec.
