Description

Error Message


Error received while attempting to "make secondary" on the original primary:
...V-106-58644-363 Cannot perform the operation. RLINK is not up to date.
 
vxprint -VPl on the new primary reports:
....state  : state=STALE
....flags : write detached consistent disconnected
 

Cause

There are two factors to be considered:

(1) The RLINK on the new primary where the take over without fast-failback synchronization was initiated will be marked "STALE" and will be detached. This is by design, and it has the purpose of forcing a full sync with the original primary when / if the host is recovered.

(2) When the original primary comes online, it is still a primary with read and write access to the volume, therefore an application or the OS could place I/O on it, thus explaining the RLINK not up to date message, even if this was up to date before the host went down.

Resolution

On the original primary, after it comes online: 

(1) Detach the RLINK using the following command line syntax:

   vxrlink [-g ] [-r ] det  

   Note: Dissociating the Replicator Log (SRL) will have the same result, as it will detach the rlink.

             The SRL would have to be Re-associated after the make secondary step.

(2) Make secondary, via the VEA GUI or by command line:

   vxrvg [-g ] makesecondary

 (3) Start the replication with the "Synchronize Automatically" option. 

To avoid the above described behavior and manual steps needed for re-establishing replication, it is highly recommended to use the "fast fail-back" sychronization method when initiating a take over on the secondary VVR host. 

 

Applies To

  • Veritas Volume Replicator for Windows 5.1 SP2 (VVR)
  • Veritas Volume Replicator for Windows 6.0.x (VVR)

Issue/Introduction

After a take over without fast fail-back synchronization was initiated on the original secondary VVR host, the subsequent "Make Secondary" on the original primary VVR host may fail with: V-106-58644-363 Cannot perform the operation. RLINK is not up to date.
