Switchover Failure Conditions
This section describes a switchover failure scenario. In this scenario, cluster-paris is the original primary cluster and cluster-newyork is the original secondary cluster.
A switchover switches the services from cluster-paris to cluster-newyork as follows:
phys-newyork-1# geopg switchover -f -m cluster-newyork srdfpg |
While processing the geopg switchover command, the symrdf swap command runs and returns errors for the EMC Symmetrix Remote Data Facility device group, devgroup1. As a result, the geopg switchover command returns the following failure message:
Processing operation.... this may take a while .... "Switchover" failed for the following reason: Switchover failed for SRDF DG devgroup1 |
After this failure message has been issued, the two clusters are in the following states:
cluster-paris:
srdfpg role: Secondary
cluster-newyork:
srdfpg role: Secondary
