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: After performing an iDRAC Hard Reset operation on certain Linux operating systems, the IPMI driver (ipmi_si for
Linux operating systems, ipmi_si_drv for VMware ESXi operating systems) may become unresponsive because of an existing
issue in the IPMI driver. If the IPMI driver becomes unresponsive, reload the IPMI driver (ipmi_si for Linux operating systems,
ipmi_si_drv for VMware ESXi operating systems).
The issue is observed on Linux kernal version prior to 3.15. An update is available in the following operating systems with Linux
kernal version 3.15 or later:
● RedHat Enterprise Linux 6.6
● RedHat Enterprise Linux 7.1
● SUSE Enterprise Linux 11 SP4
● SUSE Enterprise Linux 12 SP1
The issue is observed in the following VMware ESXi operating systems:
● VMware ESXi 5.1
● VMware ESXi 5.5
● VMware ESXi 6.0
Steps to reload the IPMI driver in Linux operating systems is as follows:
● modprobe -r ipmi_si, if the removal fails, then all applications (such as, iDRAC Service Module and OpenManage
Server Administrator use ipmi_si) should be stopped using the modprobe ipmi_si command and retry the operation.
● Alternatively, you can also restart the Host OS in order to resolve the issue.
Steps to reload the IPMI driver in VMware ESXi operating systems is as follows:
1. /etc/init.d/sfcbd-watchdog stop
2. esxcfg-module -u ipmi_si_drv => unload ipmi_si
3. esxcfg-module ipmi_si_drv => load ipmi_si_d
4. /etc/init.d/sfcbd-watchdog start
Alternatively, you can also restart the Host OS in order to resolve the issue.
