C.2.2 Pre-processing when replication is executed

The replication source volume script (RepSrcPre.js) and the replication destination volume script (RepDstPre.js) are prepared for a pre-processing script, and it is stored in the following directory subordinates. Please customize these scripts according to the processing requirements.

In the case of non-cluster operation

/etc/opt/FJSVswsrp/sh directory subordinate

In the case of cluster operation

/etc/opt/FJSVswsrp/<logic node name>/sh directory subordinate
