Issue/Introduction

Symptoms: 

• It has been observed that each time the Discover Devices operation is initiated from the Site Recovery UI, the command fails with the following error:
  
  SRA Discovery array pair is failed with error message: 'SRA command 'discoverDevices' failed. Authentication failed with User/Password for the specified connection address. Check if User/Password for the connection address is appropriate.'
  
  
• This issue is observed for the Hitachi Storage Replication Adapter.

 

Environment

VMware Live Site recovery 8.x

VMware Live Site recovery 9.x

Cause

The SRA cannot reach HORCMINST=0@X.X.X.X and failed with an error code 1003 indicating a possible network connectivity problem, firewall block, or wrong IP/hostname.

VMware SRM's vmware-dr.log indicates there is an issue on the SRA side.

FYI : 

HORCM means Hitachi RAID Command Manager, and this is a background service used by Hitachi's storage software to manage and monitor replication operations like TrueCopy, ShadowImage, and Universal Replicator.

• HORCMINST stands for "HORCM instance".

• It identifies a specific instance of the HORCM service, which allows multiple HORCM processes to run on the same server (each managing different replication configurations).

• Each instance is tied to a HORCM configuration file, typically named:

  • horcm0.conf for instance 0

  • horcm1.conf for instance 1

  • ... and so on.

• If your SRA configuration has HORCMINST=0@X.X.X.X it means SRA will try to communicate with the HORCM instance 0 on X.X.X.X

 

Resolution

1. Verify that the username and password for the specified connection address are correct.

2. Ensure that the username, password, and connection address do not contain any unsupported characters as outlined in the Hitachi Storage Replication Adapter 2.5.1 documentation, specifically under:

• Configuring SRM to communicate with RMSRA20 (SRM v8.2 or later) – Page 46

• Add Array Manager (SRM v8.2 or later) – Page 47

If the above fix does not work, then please engage your Hitachi SRA Vendor to investigate the issue accordingly.
