Hello I am quite new with Powershell and with SCOM, but I am trying to put a list of servers into maintenance and I created this script:

New-SCOMManagementGroupConnection-ComputerNameServername

$ServerList=Get-Content"\\servername\Users\Automatisering\_Infrastructure\PS Scripts\Scom Maintenance\servers.txt"

$Hours=Read-Host"How many hours do you want to set the maintenance?"

$Time=((Get-Date).AddHours($Hours))

$Comment=Read-Host"What is your comment for setting the maintenance?"

ForEach($Serverin$ServerList)

{

$HostName="$Server*"

Try

{

$Instance=Get-SCOMClassInstance-Name$HostName

Start-SCOMMaintenanceMode-Instance$Instance-EndTime$Time-Comment$Comment-ReasonPlannedOther-ErrorActionContinue-PassThru

}

Catch

{

"error$server"

}

}

but I receive for some servers the following error:

start-SCOMMaintenanceMode : The client has been disconnected from the server. Please call ManagementGroup.Reconnect() to reestablish the connection.

At \\Servername\Users\Automatisering\_Infrastructure\PS Scripts\Scom Maintenance\ScomMaintenance.ps1:14 char:25

+ ... Start-SCOMMaintenanceMode -Instance $Instance -EndTime $T ...

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : InvalidOperation: (Microsoft.Syste...anceModeCommand:StartSCMaintenanceModeCommand) [Start-SCOMMaintenanceMode], ServerDisconnectedException

+ FullyQualifiedErrorId : ExecutionError,Microsoft.SystemCenter.OperationsManagerV10.Commands.StartSCMaintenanceModeCommand

I am trying to figure out what is going wrong, especially this isn't happening for every server that I want to put in maintenance.

Hopefully someone can help me out or point me to right direction.

Thank you in advance!

Regards,

Jay

I haven't had to deploy one of these in awhile.  Has anyone experience with a hardware solution for an HP proliant 380 server for SMS secondary notifications?  I saw that the modem or device must support SMS PDU mode.

Windows Server Cluster Disks Monitoring 6.0.7303.0

So , we have missed some cluster disk free space situation and after some investigation  i can see that there are totally 

No cluster disk on monitoring. They all gone.

Cluster Disks Discovery/Cluster Shared Volume Discovery/Cluster Name Discovery are enabled by default and they are not turned off by overrides. No errors on agents where cluster disks are

What can i do for troubleshooting ?

Is there a way to see which machines are using which management packs?

We know that the MPs are loaded on the scom management servers but we are not sure which machines are using our Universal Linux MP, or our Windows 2008 R2 MP, etc.

Maybe this is a sql query?

Thanks in advance.

Still using SCOM 2007 R2. We have the MP for 2012 installed and the discovery for mount points enabled. I can see the mount points as logical disks. However, SCOM does not alert when free space gets below the alert threshold.

Logical disks on 2012 servers with drive letters do not have the same issue and alert when they should.

Is this a known issue with monitoring mount points on 2012 servers from SCOM 2007 and, if so, is there a fix for it?

Thanks

Hi,

Here we have a requirement to find total C:\ drive disk space on each windows agent servers and how much free space is available on these agents. We tried to pull the reports using Reporting tab, as we have 900+ agents are configured, its getting DB error. Do we have any alternate way to fetch the details from Data Warehouse DB server using SQL query. I am not familiar with SQL tables and views as well with SQL queries. If you guys knows the table / views name where the logical disk space performance reports being pulled out, pls share the details. Will take the help from our internal SQL team to pull the details.

We are using SCOM 2012 Management servers and the SQL box is 2012

The desired output is like;

1.Agent Name

2.Total Disk space

3.Available disk free space

Hello,

I have a network device (router01.contoso.com) being monitored in SCOM 2012 R2 using SNMP.  I'm using a community string (secretWord) to monitor it.  I'm able to pull Processor/MEM/Interface details.

I want to monitor BGP connection details on a virtual interface by probing a specific OID, however, that OID is only accessible by specifying a different community string (specialSecretWord).

Creating a SNMP monitor is no problem.

My question - Is there a way to use different community strings to query the same device?  If so, how?

Thank you in advance,

Hi,

Bear with me, a somewhat complicated story here.

One of our servers ASR booted two some days ago but we didn't notice it (the Heartbeat Failure and Failed to Connect to Computer went from new to close and thus we didn't see it because our View only shows New alerts).

Although, since it was an ASR boot, our "HP Windows (WMI ASR reboot occorued."-alert should trigger, and it did! But somehow it went to Closed immediatley with no sign on who closed it. So the question is, why did SCOM close it automatically? Since its a rule, no auto-resolve is configured (screenshots attached below).

We also have a custom rule that reacts on Eventid 6008 in the System log (The previous shutdown at xx:xx:xx on xxxx-xx-xx was unexpected) that is also set to Closed with no trace on who actually Closed it.

Also - we received the "SQL Server Broker disabled"-alert two days before all this, could that have something to do with it?

Thanks for your help.

"Health Service limits: maximum 128 dataitems per a workflow, maximum 5120 dataitems simultaneously"

The above statement seems to be somewhat known between SCOM admins. Is there any authoritative source for this information or any way to measure these values?

Are these values applicable to Health Services running only on Agents or also Management Servers/Gateways?

PS.

I know in UR 5 there are some registry keys that allow to override the hard coded value for the agent :https://support.microsoft.com/en-us/kb/3023138

Thanks.

Hi, I have an issue with proper display alerts for operators. I have some groups with specific objects and I scoped operator role for that groups only. Objects are displayed correctly in SCOM Console but I get also warning alerts from SCOM itself in Active Alerts view like "Operations Manager failed to start a process" or "Worklfow Initialization: Failed to start workflow that run a process or script"

Those objects in groups are windows computers and vmware.

Anyone know why this might be happening?

Hi,

Is there a PowerShell script about that can install a UR to a list of servers (e.g. the amd64-agent .msp file from UR9) from my SCOM server?

(I'm finding that too often many hours are spent in updating agents that fail to get the updates from the SCOM GUI and for those that are manually installed).

Thx very much,

John Bradshaw

Hello everyone,

===

As you can tell from the subject, I`m having difficulties exporting a report that I made on Report Builder.   I could save it as rdl file but i can only open that report through the Report Builder itself.   I have this report runs a query to read from MS SQL server.   It runs smooth, is there any way i can have this report into SCOM?

Abdullah

hi Team,

We have 3 MS servers in Data center 1 and 1 in other data center 2, in total 4 MS servers in a single management group.

as per the "All Management Servers Resource Pool" alert failure is caused by  "Majority of collection Management Servers are not running".

just want to understand more on this.

what is the minimum number of MS servers to be online. this will help me in planning a simple DR activity and HA test.

If 3 MS goes down in data center 1 will the MS in data cent 2 takeover all the roles or do we need to have extra MS.
