When Using EMC Symmetrix for Data Replication, `geopg switchover` Command Fails (6456435)

Problem Summary: EMC SRDF does not allow role changes when domino effect is on. If adaptive copy write pending and domino modes are set, you see failure messages that are similar to the following example:

# geopg switchover -f -m no-1 srdfpg
Processing operation... The timeout period for this operation on each cluster is 3600 seconds 
(3600000 milliseconds)...

Resource groups "fo-rg,scal-rg" is unmanaged.
Failed to perform the protection group role change for device group  testdg.

# Aug  2 11:05:14 pbrew2 symrdf[29990]: 'Suspend' for device group testdg - Cannot proceed in the 
current RDF state except if the Symmetrix force flag is used. Note that the Symmetrix force flag is 
not allowed to be used by default in RDF control operations

Aug  2 11:05:17 pbrew2 symrdf[11]: 'Swap Personality' for device group testdg - The device is not 
in a valid RDF state for this operation

Workaround: Use failover instead of switchover.
