I've a vob, please find my vob detail

It has two sites on site when I run lsepoch I got output as below

Oplog IDs for row "ANTWERP_3" (@ beantsu0090.be.alcatel-lucent.com):

On other site it has

But when I run the syncreplica command on both sites it shows as Target replica(s) up to date

/usr/atria/bin/multitool syncreplica -export -fship CHENNAI_1@/vobs/esam/configspecs

Could you please help on this case, somewhere I'm missing.

Solution

You can find two avenues to pursue in "Different epoch values":

either on the target side (if you have access), import any pending sync packet (multitool syncreplica -import -receive)
or (my solution) re-exporting the all vob: multitool mkreplica -export -maxsize 200m -nc... and importing it

Check also the technote "Replicated VOB cannot import or export packets from scheduled jobs"

ERROR: command './bin/multitool syncreplica -export  -fship    replica:<replica-name>@/<vob-tag> >&2' encountered error.
Target replica(s) up to date. No export stream generated.

In that technote, the cause was Cause a duplicate replica created on the same host.

Diagnosing the problem

On the host, run a multitool lsreplica -l command while inside a view and VOB context. By examining the output, you should see there is more than one replica on the same host which is invalid.

Resolving the problem

Contact IBM Rational Client Support for assistance in resolving this issue providing the following information:

Output of a cleartool describe -l vob:<vob-tag> on in the "good" VOB to obtain the actual replica name.

Output of a multitool lsreplica -l to get the replica name of the duplicate replica on that host. This will also identify the mastering replica.
