Hello,
You can select volume(s) you wish to sync up by running the command below
#vradmin =g <dg_name> syncvol <vol_list>
where <vol_list> is " a comma-separated list of volume names or volume set names. "
Please ref to the vradmin man page for the command syntax details
To sync CFS vols, you can run vradmin syncvol command on CFS primary
To find out which node is the CFS primary, run the command below
#fsclustadm -v showprimay </cfs_mount_point>
Please note that the each CFS vols may have different node as cfs primary.
For VVR data replication network bandwith, please ref to this technote https://www.veritas.com/support/en_US/doc/129692942-129692945-0/uxrt-731_id-SF180175499-129692945
Thhe best way to do CFS replcation is to issue the sybcvol command on CFS primary when the system/network loads are not high
Regards,
Frank
