Environment

VMware ESXi 6.7.x
VMware ESXi 6.5.x

Cause

  • The HBA driver "smartpqi" always requests the physical memory address below 4 GB range
  • This fails to get additional memory If there was no any DMA memory available in that range.
As lack of memory, the 3th utility "SSA CLI" will slowly get feedback from the HBA driver.
  • This will lead to host management agent "hostd" to turn non-responsive 

Resolution

  • The latest driver "smartpqi" version "1.0.3", an enhancement was added to fix this issue.
  • It's release on Jan 2019.
  • Download VMware ESXi 6.5 smartpqi 1.0.3.2035 SAS Driver for HPE Smart PQI controllers

In the release note snippet :
Fixes & Enhancements:
---------------------
* Added an enhancement to remove "Below 4 GB" DMA memory usage.
  The driver always requests the physical memory address below 4 GB range and there might not be any DMA memory available in that range.

Note: As this enhancement,it's requested to use the 64-bit SSA CLI utility to work with the latest driver.


Workaround:
  • Sometimes, the host will be resume by restarting the hostd.
# /etc/init.d/hostd restart


Additional Information

Impact/Risks:
  • The ESXi host will be un-responsive from the vCenter
