Known issues on VMware ESXi operating systems
Issue 1: IPMI driver may become responsive after iDRAC
Hard Reset operation on certain VMware ESXi operating
systems
Description: After performing an iDRAC Hard Reset operation on certain VMware ESXi operating systems, the IPMI driver (ipmi_si_drv
on ESXi 6.5U2 and ipmi on ESXi 6.7U1 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_drv on ESXi 6.5U2 and ipmi on ESXi 6.7U1 Operating System).
Workaround: The issue is observed on iDRAC Service Module v2.3 and later supported ESXi versions.
To reload the IPMI driver:
• 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.
Run the following commands
esxcli system wbem set -e 0
esxcfg-module -u ipmi_si_drv/ipmi => unload ipmi_si_drv/ipmi
esxcfg-module ipmi_si_drv/ipmi => load ipmi_si_drv/ipmi
esxcli system wbem set -e 1
• Alternatively, the administrator can also restart the Host OS to resolve the issue .
Issue 2: iSM uninstall or wbem stop causes ungraceful
stop of iSM CMPI modules
Description: iSM uninstall or wbem stop causes ungraceful stop of iSM CMPI modules thereby resulting in system V semaphore leaks.
Recurring system V semaphore leakage impacts iSM functionality.
This is a known issue affecting vSphere ESXi 6.7. For more information, see https://kb.vmware.com/s/article/66775
