Known Issues and Resolutions
Issue 1
Description: If DSET 3.4 or later is running, and iDRAC Service Module is shut down or uninstalled; a Watchdog Timer Expiry
event is observed.
Issue 2
Description: On Microsoft Windows 2012 operating systems; if an iDRAC reset operation is performed when any of the iDRAC
sessions are opened using iDRAC access via Host OS feature, then the connection between iDRAC Service Module and iDRAC
may not be re-established. Also, the Microsoft Windows service IP Helper might stop running.
NOTE: Microsoft KB3156418 update package fixes the above problem.
In such scenarios, the following steps will resolve the issue.
1. Restart the iDRAC Service Module.
2. Restart the Microsoft Windows IP Helper service.
3. If Open Manage Server Administrator is running; restart the dsm_sa_datamgr service.
Example:
● Open iDRAC GUI via the iDRAC access via Host OS feature.
● Perform an iDRAC firmware update from the GUI. This will reboot iDRAC with the new firmware.
● The iDRAC Service Module in the Host does not restart communication with iDRAC.
● IP Helper services stops running.
You can configure the Windows Remote Management (WinRM) Listener using a server authenticating certificate. If the
server authenticating certificate is not available, iDRAC Service Module will force-enable the WinRM listener using a self-sign
certificate. To configure the Windows Remote Management (WinRM) listener, you can create a self-signed certificate using
the PowerShell cmdlet New-SelfSigned Certificate from Microsoft Windows Server 2012 or later. In operating systems prior to
Microsoft Windows Server 2012 you cannot create a self-signed certificate due to the absence of PowerShell cmdlet.
Issue 3
Description: After performing an iDRAC Hard Reset operation on certain Linux operating systems, the IPMI driver (ipmi_si) may
become unresponsive because of an existing issue in the IPMI driver. If the IPMI driver becomes unresponsive, reload the IPMI
driver (ipmi_si).
The issue is seen on Linux kernel version prior to 3.15. An update is available in the following operating systems with Linux kernal
version 3.15 or later.
Steps to reload the IPMI driver:
● modprobe -r ipmi_si — If the removal fails, then all applications (such as iDRAC Service Module and OpenManage
Server Administrator) using the ipmi_si need to be stopped and retry the operation.
● modprobe ipmi_si — Alternatively, the administrator can also restart the Host OS to resolve the issue.
Issue 4
Description: After performing an iDRAC Hard Reset operation on certain VMware ESXi operating systems, the IPMI driver
(ipmi_si_drv) may become unresponsive because of an existing issue in the IPMI driver. If the IPMI driver becomes
unresponsive, reload the IPMI driver (ipmi_si_drv).
