Hi
I want to check my Proliant Hardware RAID 5. I dont want to use SNMP. Can WMI lookup be used? |

What exactly means "check"? What exactly parameters do you want to check?
E.g.
- Free Space can be checked by UNC test method.
- Some basic disk parameters can be checked by standard Windows WMI classes.
- if you want to get some technical information from this controller, check the manual that comes with your device.
As I know if you install "HP Insight Management WBEM Providers", you will get WMI namespace for your HM devices.

May I ask why?
Usually SNMP works faster and uses much less system resources than WMI

Hi
I dont want SNMP because it may be configured on all the servers 500+. I want HM to make all the test, therefore a WMI lookup will be easy if it can get the the RAID broken information. I will make a small script to handle the WMI.
I only want to check is the RAID 1 or 5 is consistent, if one disk fail the WMI maybe have the information? |

Not sure I understand. You want to create your own script that will check 500 systems (single test item for 500 hosts)?

Probably.
We do not have such hardware so I cannot tell you for sure 
Why don't you ask HP support team?

You should reconsider not using SNMP.
The HP agents that are required to show RAID health (including via WMI as far as I know) require that you install SNMP (it's a pre req in the PSP install).
Once in place it's trivial - check SNMP for OID
1.3.6.1.4.1.232.3.1.3.0
.. anything other than a 2 is a problem. Check the MIB if you want to get fancy with it, but for our 1200+ servers we use this as a pointer to check Insight Manager for logs, additional info etc. - it's just a good first alarm for the Ops. If you want to get fancy, you can get the other staus codes from the MIB.
You only need a read only community defined. You can restrict lookup for snmp from only the localhost and the server performing the tes (RMA or Host Monitor server) - I don't see any big security risk in this config, and SNMP is straightforward to add to most OS. |

Dude! You rock! Thank you for sharing.
And when your finished enabling all your devices you can use this free snmp scanning tool to verify them all. It operates as a single exe. Perfect for the toolbox.
