5. Click DataMover.
6. Change the DataMover.HardwareAcceleratedMove setting to 0.
7. Change the DataMover.HardwareAcceleratedInit setting to 0.
8. Click VMFS3.
9. Change the VMFS3.HardwareAcceleratedLocking setting to 0.

Kindly go through the below more information:
Note: Please be aware of the recently published ETA 207784: “VNX: Storage Processors may restart if VMware vStorage APIs for Array Integration (VAAI) is enabled resulting in potential data unavailable”.

This ETA reports an issue that can cause SP panics on both VNX1 and VNX2, and the issue is described in clear detail within.

(TLDR?: The problem is caused by an error on ESX hosts that causes an SP to Bugcheck. If the Bugcheck were met during the Block upgrade, it could potentially lead to DU for the customer.

For example, if the SP is rebooting as part of the NDU and the condition is met on the host, the Peer SP would Bugcheck, resulting in both SPs being offline simultaneously).

Q: View all communication connection links & Active Locks on symmetrix.

Firstly, if you want to know, what all applications are actively communicating with your symmetrix array, run the below CMD
//list all the connection for an Symm Array
symcfg -sid xx list -connections

while running cmds if you any Symlock issues, run thebelow CMD to list the active Locks

//List the active Lock on Symmetrix
symcfg -sid xx list -lockn all

How to setup symavoid file for Symmentrix

Possible errors: ERROR [em.bp.DEPLOY] (EJB default - 1) DeployService.waitForDeployed:Failed to detect E:\Program Files\EMC\SMAS\jboss\standalone\deployments\domain-symm.ear.deployed

Resolution:
For Windows:
1. open cmd prompt, run the below cmd
cd \program files\emc\symapi\config\

note: most folks will install symapi on d: or other directories, in that case make sure cmd.exe is directed in the right director, or else you will get below error message.

C:\>cd \program files\emc\symapi\config\
The system cannot find the path specified.
what yo do now (search the root director where symapi is installed)
C:\>d:
D:\Program Files\EMC\SYMAPI\config>

2. Run the below cmd to create symavoid file, if its allready exists, notepad will be opened, or else prompt will appear requesting to create new file.
D:\Program Files\EMC\SYMAPI\config>notepad symavoid

3. Now Enter the array serial number that you would like to avoid by the local host to discover.
If you like to know the current view able arrays, run the below cmd
>>symcfg list.
note: For multiple arrays, put each serial on its own line. Like below
Example:
000190101186
000192601175
000192601103
000195701130

4. Save (as normal file, not .txt) and close.
Note: this is really important to make sure saved file is not saved in text format(.txt), File type should show File
//run the below cmd to remove the entries from the records.
symcfg remove -sid 1186
//run the below cmd to make sure symavoid Array's are not listing back again.
symcfg discover

SRM - SRA command 'discoverArrays' failed + Cannot enable the array pairs

I am here today to share some of the my experience that face in integrating SRM (SRA 2.2) with RecoverPoint v4.1.2.

Issue:SRA command 'discoverArrays' failed.
Cause:
Failed opening session for user to site mgmt IP.
Please see server logs for further details.

Fix:
enable Https at the vCenter server of both the production and the recovery site,
open a Windows command prompt and go to the directory
C:\Program Files\VMware\VMware vCenter Site Recovery Manager\storage\sra\array-type-recoverpoint

> Run (at production and recovery site):
command.pl --useHttps true

> after the cmd run successfully, we will see the http file on the file directory.

>enable https in recovery Point on Both RPA Cluster
Login to the RPA Cluster with admin account

Tricky part is here, some rpa come with Http & Https both enable. To fixed our issue we need only Https.

If it is already enable don't change anything, Like below

>> Register the RPA's Cluster in SRM with boxmgmt Account

Another issue you might get Issue: Cannot enable the array pairs - option Greyed out
This is because of SRM Manage Mode should be enable at the RecoverPoint CG Level.

If you still face any issues, Comment the post, i will try to answer in best of my knowledge.
