3PAR Remote Copy DR

[erichuang0616]

Hi,

I have installed remote copy by RCFC, source storage node name is CCH_3PAR_14F and DR site is CCH_3PAR_2F. All remote copy group is sync mode and CCH_3PAR_14F sync to CCH_3PAR_2F.

Recently we run failover testing on both site. If we shutdown source site, that is CCH_3PAR_14F not available, we found

we cannot do any actions such as failover remote_copy groups to CCH_3PAR_2F (refer the attachment). Why? As we know

If the source site is failed, we need to failover all remote_copy groups to DR site, so we simulate to shutdown source site 

storage,then how to failover all groups into DR site ?

Any hints are appreciated  

Best Regards,

Eric Huang

From the DR system Run the CLI commands
$showrcopy groups
Take a note of the name of your remote copy group name <group.r.xxxx>

$setrcopygroup failover <group_name>
Note: # setrcopygroup failover -t <target_name> command will Reverse the role of all volume groups on the system that is still in normal operation (the failover system)

Again run the CLI command on DR system
$showrcopy -d groups
Check the Role
