WMI to query the current RAID status

Question

Hi guys...

Im in charge of monitoring lots of servers, all Dell and a few weeks back someone else noticed that one of our servers was having problems with one of the disks.

I've logged in to OMSA and the RAID status was degraded because one of the drives was failing.

I've noticed that this information was worth to monitor (we didn't noticed earlier hahaha).

I've been surfing trough root\cimv2\Dell and i couldn't find the namespace that holds the virtual disks information that IS showing on OMSA.

The only "similar" thing that i've found was Dell_EsmLog but it's not the same at all.

The one server that i'm testing this using server 2008 r2 and OMSA 7.4

The guys from Dell told me to try Open Manage Essentials. It's good but requieres to create a machine on every site and that costs money (to buy the hardware) and we already have a monitoring system that can reach all sites with no problem but it uses WMI.

Please help since the guys a dell support couldn't help me.

Regards.

Francisco.

Hi, Unfortunately there is not a way to do this with WMI. Storage health is not able to be monitored with that method, SNMP and IPMI are the methods that are available for monitoring storage health.

Hi Josh.. That is bad news. Do you know how can i do this with SNMP?... I'm still confused with that method. Regards. Francisco

It depends on what software you are using for monitoring, but you would import the mib files and the software should be able to query the server with OMSA and it should respond with the status of the hardware. ftp://ftp.dell.com/Manuals/all-products/esuprt_software/esuprt_ent_sys_mgmt/esuprt_ent_sys_mgmt_opnmng_svr_admin/dell-opnmang-srvr-admin-v7.4_Reference%20Guide3_en-us.pdf

What model server is this?

Hey Josh...

We have a variety of servers from PowerEdge 850 to PowerEdge R720 but the most importants are the PowerEdge 2950 and PowerEdge R710 and R720.

We currently have a software called NextNine to monitor our servers. We've also have (recently installed) Dell OpenManage Essentials because we had a disk failure and no one knew about it because there is no WMI to capture it.

NextNine can handle SNMP but i need to know where to look on the MIB since there are too many variables and data and namespaces and etc :).

Any clue on where can i exactly find this info?.

Thanks so much!

Francisco.

Are you just looking for monitoring storage? In the guide I linked to in the last post, page 407 arraydiskstate should be what you want.
