Discovery



Troubleshooting a discovery task that fails to be created or executed

Make sure DSM Essentials Task Manager service is running in Windows Services

Devices discovered with WMI are classified as Unknown

WMI discovery will classify a device as Unknown if the credentials used are in the Administrators group and used for the discovery range.

Click here for more information

ESXi servers are classified as Unknown

Increase the timeout setting to 10 and retry setting to 4 in the WS-MAN page for discovery wizard

Important Discovery information and Dell OpenManage Server Administrator (OMSA)

OMSA must be installed on Dell PowerEdge servers to be discovered and managed using the SNMP protocol. OMSA can be installed using the OME console. PowerEdge servers using WMI can be discovered without OMSA. The servers will not be classified as Unknown or Computer. Management capabilities in OME are limited if OMSA is not installed.

Servers appear under the Unknown node in the device tree

Systems discovered with SNMP only without OMSA installed will be classified as Unknown and displayed under the Unknown device group. Check the SNMP settings if OMSA is correctly installed on the managed node
Note: SNMP community strings are case sensitive

Start the Services MMC on the managed node and open the properties page for SNMP Service
Add the OME server on the Security tab under Accept SNMP packets from these hosts

Run /etc/init.d/dataeng enablesnmp followed by /etc/init.d/dataeng restart on Linux servers

Run the Services test in the Troubleshooting Tool to determine if the following conditions are met

dsm_sa_datamgrd
dsm_sa_eventmgr
dsm_sa_snmpd
dsm_om_shrsvcd
dsm_om_connsvcd

Restart the services

Devices have the status System Down determined and frequency of checking device status

The connection state shows 'ON or 'OFF' under device summary table in the LHS. The removal of the device from the network by either powering it off or removing the NIC cable will result in a status of 'System Down'. The device is considered down if it does not respond to the ping application. Polling for connection state defaults to 1 hour. The frequency of polling can be changed

Troubleshooting a server in Unknown status or not returning inventory data even after SNMP is enabled and OMSA is installed on the target server

Confirm the DSM SA Data Manager Service is running in Windows Services on the target server. Restart the service if necessary and re-run the inventory task.

Discovering EqualLogic storage arrays

EqualLogic arrays are discovered with the SNMP v2 protocol. Choose SNMP in the OME discovery wizard along with the appropriate 'read' community string. Include the IP address of the EqualLogic Group and IP addresses for all the members in the discovery range.

The iDRAC 6 IP address shown as 0.0.0.0 in OME

Upgrade the iDRAC firmware

EqualLogic blade devices are not classified under the Modular group

Confirm the chassis service tag in EqualLogic is populated for that to be classified under Modular group

Discovery of PowerConnect 8132 is time consuming

Update to the latest firmware

KVM 4332DS is not classified under KVM

Update the firmware

iDRACs are being deleted and re-added during a long discovery and inventory

Enable the DNS iDRAC to Server name correlation

DSA (LASSO) collection of logs from EqualLogic group upon receiving an event is incorrect or incomplete

Discover EqualLogic storage groups using the Group Management or Storage Group IP address only and not include any of the member IP addresses in the discovery range configuration.

Troubleshooting the "invalid package signature" error when tasks such as OMSA deployment, iDRAC Service Module deployment or system update fails

Install the VeriSign Class 3 Public Primary Certification Authority - G5 certificate on the server running OME

The Dell Server appears in the OEM device group

Perform a Lifecycle Controller wipe using winrm from a computer on the same network using the command below
Note: The LifeCycle Controller wipe operation is destructive. It will wipe out your iDRAC License key. Export the key so it can be restored. Refer the appropriate iDRAC manual. winrm i LCWipe -u:[iDRAC_root] -p:[iDRAC_PWD] -r:https://[iDRAC_IP]/wsman -SkipCNcheck -SkipCAcheck -encoding:utf-8 -a:basic
Note: The command will ReturnValue of 0 if it was successful. The iDRAC will inaccessible for a short period of time. The iDRAC will be back to a default state with an IP address. Run an OME discovery in order to re-categorize the server in the device tree.

Unable to discover iDRAC/chassis/ESXi servers using WSMAN protocol

Check that the devices have valid certificates installed

The devices in Device tree disappear during discovery

Edit the dconfig.ini located in SysMgt\Essentials\configuration
Change the following line PRIVATE_MAC_EXCLUDE_LIST to
PRIVATE_MAC_EXCLUDE_LIST=127.0.0.1,0.0.0.0,005345000000,33506F453030,505054503030,0000FFFFFFFF,204153594EFF,000000000000,00000000000000e0,020054554e01,204153594eff,0000000000000000
Save and restart the OME services
Note: Administrative privileges are required to edit dconfig file. Make a backup copy of dconfig.ini file before making changes.

Inventory



Troubleshooting inventory task failures

Make sure DSM Essentials Task Manager service is running in Windows Services

Updating inconsistent data in the device details and Modular Enclosure Information report for a PowerEdge VRTX CMC after performing discovery and inventory using WS-Man when all the server slots of the chassis are empty

The PowerEdge VRTX only reports data for server slots with a modular server present and does not report any data for empty server slots.

PCIe Information and Virtual Adapter Information table in the PowerEdge VRTX device details page continue to show the server name of a modular server that has been removed from the VRTX chassis, after the CMC has been re-inventoried

This behavior will impact data tables which show association of the modular server slots to the PowerEdge VRTX chassis resources such as the PCIe Information, Virtual Adapter Information and Virtual Disk Access Policy Information tables. To update these tables to reflect the correct data the instance of the VRTX CMC must be removed from the device tree and re-discovered and inventoried.

The output power supply shown as 0 watts in the PowerSupply info table for my server with a cabled PSU

The output power supply info will be shown as 0 watts for servers with cabled PSU such as a T430 server.

Health



Retrieving the health status of Dell PowerEdge servers

OMSA should be installed on the server

OME displays the power supply health as Normal when the redundant power supply has lost power

Upgrade OMSA

The device count and rollup health show 0 when the REST API command is used for a group marked hidden in the OME Console

The REST API used to return information about a Device Group ( /DeviceGroups/DEVICEGROUPID ) should not be used on device groups that are marked hidden in the OpenManage Essentials console

The PowerConnect W series switch not displaying device health

The health attribute is only available if the PowerConnect W switch is in the master role

System Update



Loading a Dell catalog for software update or errors when trying to run software update tasks

Download the catalog to the OME server directly
Browse for catalog.xml file on the local system
Load catalog and verify it shows as loaded in OME. Download to get the latest catalog from ftp.dell.com for troubleshooting purposes
Create software update tasks. Information can be found in the task details when the task fails.
Change Internet Explorer security settings to Low if tasks will not run when executed

Order installation of packages

Packages are applied in the following order.- Driver- Firmware- Firmware ES- BIOS- Application

The error "Attempted to perform an unauthorized operation." occurs when performing a catalog import task

Change the folder and share permissions to allow the user access
When using Repository manager as you catalog source make sure that the packages associated with the RM generated catalog are present in the same folder as the catalog.
If the packages are not present in that folder you would see an invalid path result for the packages.

Configuring Internet Explorer with Enhanced Security Configuration so OME can utilize all features that use resources from Dell Online

Add *.dell.com to the Trusted sites security zone.

The error "Access to path 'C:\Program Files (x86)\Dell\SysMgt\Essentials\SystemUpdate is denied" occurs running system updates

In File Explorer navigate to C:\Program Files (x86)\Dell\SysMgt\Essentials\ and create a new folder named SystemUpdate

The System Update task displays as failed even though the server updated successfully

The target server required a reboot and did not respond within 30 minutes. Check the server status and run the inventory separately for the server.

The inventoried server does not have a software inventory or displays as a non-inventory state when an inventory task was executed

Install OMSA on the server or verify the services are started
Check the OMSA log located at C:\Program Files\Dell\SysMgt\oma\log
Delete all of the files except for the cachecfg.txt and restart the DSM SA Shared Services within Services.msc.

Dell PowerEdge servers are discovered and inventoried, identified as non-compliant and the update task completes quickly

Provide NTFS Full Control permissions to the C:\Program Files (x86)\Dell\SysMgt\Essentials\SystemUpdate folder
Re-run system update tasks on the same target when they have not completed
This will result in OME resending the same updates again.

The Error "Exception message: Error: 1205, Procedure: usp_Catalog_Insert, Message: Transaction (Process ID 69) was deadlocked" occurs

Use a different tool to mount the ISO

Pushing updates to VRTX Chassis

The VRTX chassis must be discovered and inventoried using WS-Man protocol for OME to push updates
