PATCH NAME
----------
InfoScale Storage 7.1 Patch 100


OPERATING SYSTEMS SUPPORTED BY THE PATCH
----------------------------------------
Windows Server 2008 R2 X64
Windows 2012 X64
Windows Server 2012 R2 X64



BASE PRODUCT VERSIONS FOR THE PATCH
-----------------------------------
   * InfoScale Storage 7.1


SUMMARY OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
Patch ID: IS 7.1 CP1
* 3919881 (3917778) Reduced I/O performance and memory leak may be observed in case of TRIM-based reclamation


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following incidents:

Patch ID: IS 7.1 CP1

* 3919881 (Tracking ID: 3917778)

SYMPTOM:
On devices where TRIM-based reclamation is enabled, you may observe the following issues:
- Issue 1: Application I/O performance may be reduced when TRIM request is being processed
- Issue 2: Memory leak may take place for vxio non-paged pools

DESCRIPTION:
On devices where TRIM-based reclamation is enabled, you may observe the following issues:
- Issue 1: The application I/O performance may be degraded when a TRIM request is being processed. This issue occurs because of a conflict in read-write locking.
- Issue 2: Memory leak may take place for vxio non-paged pools. This issue occurs if multiple file delete operations are performed while the TRIM request is being processed.

RESOLUTION:
The InfoScale Storage and InfoScale Enterprise behavior to handle the read-write locking and the memory leak during multiple file delete operations is modified as part of this hotfix.
Even when TRIM is enabled, the read-write locking and the file delete operations now do not affect the application I/O performance and no memory leak occurs too.
FILE / VERSION:
vxio.sys / 7.1.7003.448 
ddlprov.dll / 7.1.7003.448 
vdsprov.dll / 7.1.7003.448



INSTALLING THE PATCH
--------------------
What's new in this CP
=====================|

The following hotfixes have been added in this CP:
 - Hotfix_7_1_07003_448_3919881_x64 
 
For more information about these hotfixes, see the "FIXED_INCIDENTS" section in this Readme.


Install instructions
====================|

Download the appropriate cumulative public patch (CP) executable file to a temporary location on your system.
Note: You can install the CP directly on the host machine without downloading the executable file using the Veritas InfoScale Operations Manager (VIOM) Server

Each cumulative public patch includes the individual hotfixes that contain enhancements and fixes related to reported issues.
See the "FIXED_INCIDENTS" section for details.

Before you begin
----------------:
[1] Ensure that the logged-on user has privileges to install the CP on the systems.

[2] One or more hotfixes that are included with this CP may require a reboot.
Before proceeding with the installation ensure that the system can be rebooted.

[3] Veritas recommends that you close the Cluster Manager (Java Console) and the Veritas Enterprise Administrator (VEA) Console before installing this CP.

[4] Ensure that you close the Windows Event Viewer before proceeding with the installation.

[5] Ensure Veritas InfoScale Operations Manager server is deployed

[6] In case of installing the CP using Veritas InfoScale Operations Manager (VIOM) Server, the machines must be added as host on which you want to install the CP.



To install the CP in the silent mode
-----------------------------------:

Perform the following steps:

[1] Double-click the CP executable file to start the CP installation. 

The installer performs the following tasks:
    - Extracts all the individual hotfix executable files
      The files are extracted at %commonprogramfiles(x86)%\Veritas Shared\WxRTPrivates\<HotfixName>
    - Runs the pre-install tasks
    - Installs all the hotfixes sequentially
    - Runs the post-install tasks
The installation progress status is displayed in the command window.

[2] After all the hotfixes are installed, the installer prompts you to restart the system.
Type Y to restart the system immediately, or type N to restart the system later. 
You must restart the system for the changes to take effect.

Note that the installer prompts for a system restart only if hotfixes that require a reboot are included in the CP and are installed.

To install the CP using the command line
----------------------------------------:

Use the VxHFBatchInstaller.exe utility to install a CP from the command line.
The syntax options for this utility are as follows:

vxhfbatchinstaller.exe /Patch:<CPName> [/PreInstallScript:<PreInstallScript.pl>] [/silent [/forcerestart]]

where,
    - CPName is the cumulative patch executable file name without the platform, architecture, and .exe extension.
For example, if CP executable name is CP1_IS_71_W2K12_x64.exe, specify it as CP1_IS_71.

    - PreInstallScript.pl is the Perl script that includes the pre-installation steps. These steps forcefully kill the required services and processes in case a graceful stop request does not succeed.
    Veritas recommends that you use this option and script only in case the CP installer fails repeatedly while performing the pre-installation tasks.

    - /silent indicates the installation is run in a non-verbose mode; the installer does not prompt for any inputs during the installation.

    - /forcerestart indicates that the system is automatically restarted, if required, after the installation is complete.


Perform the following steps:
[1] From the command prompt, navigate to the directory where the CP executable file is located and then run the file to extract the contents to a default location on the system. 
The installer displays a list of hotfixes that are included in the CP.
    - On 64-bit systems, the hotfixes executable files are extracted to:
      "%commonprogramfiles(x86)%\Veritas Shared\WxRTPrivates\<CPName>"
      
[2] In the same command window, run the following command to begin the CP installation in the silent mode:
vxhfbatchinstaller.exe /Patch:<CPName> /silent

For example, to install a IS 7.1 CP for Windows Server 2012, the command is:
vxhfbatchinstaller.exe /Patch:CP1_IS_71 /silent

The installer performs the following tasks:

    - Extracts all the individual hotfix executable files
      The files are extracted at %commonprogramfiles(x86)%\Veritas Shared\WxRTPrivates\<HotfixName>
    - Runs the pre-install tasks
    - Installs all the hotfixes sequentially
    - Runs the post-install tasks
The installation progress status is displayed in the command window.

[3] After all the hotfixes are installed, the installer displays a message for restarting the system.
You must restart the system for the changes to take effect.

Note that the installer prompts for a system restart only if hotfixes that require a reboot are included in the CP and are installed. The installer automatically restarts the system if you had specified the /forcerestart option in step 2 earlier.


VxHFBatchInstaller usage example
---------------------------------:

[+] Install CP in silent mode, restart automatically:

vxhfbatchinstaller.exe /Patch:CP1_IS_71 /silent /forcerestart

Post-install steps
==================|
The following section describes the steps that must be performed after installing the hotfixes included in this CP.

Ensure that VIP_PATH environment variable is set to "C:\Program Files\Veritas\Veritas Object Bus\bin" 
and NOT to "C:\<INSTALLDIR_BASE>\Veritas Object Bus\bin". Assuming that C:\ is the default installation drive.

Known issues
