HOTFIX NAME
----------
Veritas Resiliency Platform Hotfix 3.3.2.2

APPLIANCES SUPPORTED BY THE HOTFIX
----------------------------------------
Infrastructure Management Server

BASE PRODUCT VERSION FOR THE HOTFIX
-----------------------------------
Veritas Resiliency Platform 3.3.2


SUMMARY OF ISSUES FIXED BY THE HOTFIX
---------------------------------------
Hotfix 3.3.2.2:
* STESC-2532 (VRP-23481) - vxtap IO hang when doing memory performance testing on CentOS 7.4
* VRP-23460 - IOTAP Package Installation failed if boot and root on seprate partition on SLES platform

DETAILS OF ISSUES FIXED BY THE HOTFIX
--------------------------------------------
This hotfix fixes the following JIRA issues:

* STESC-2532 (Fix Tracking ID - VRP-23481)

SYMPTOM: vxtap IO hang when doing memory performance testing on CentOS 7.4. The same behavior is observed on other versions of RedHat and SUSE as well.

DESCRIPTION: CentOS VM hangs when stress testing is performed on the VM. The VM works fine with same stress testing without the vxtap driver.

RESOLUTION: When stress testing is performed the memory consumption of the OS increases to such high level that vxtap does not get enough needed memory and used to go into sleep while trying to replicate the IO being processed.
Fix involves temporarily pausing the replication when vxtap detects that the available memory is beyond a threshold value. When enough memory is available replication processing resumes.

* VRP-23460

SYMPTOM: Installation of IOTAP addon fails on SLES platform

DESCRIPTION: IOTAP Package Installation failed if boot and root on seprate partition on SLES platform.

RESOLUTION: Handled the configuration of separate boot and root partition as part of installation.
