The vradmin set command allows you to disable compression on a per secondary host basis.
To disable compression
# vradmin -g diskgroup set local_rvgname [sec_hostname] compression=off
The argument local_rvgname is the name of the rvg on the local host and represents the RDS.
The argument sec_hostname is the name of the Secondary host as displayed in the output of the vradmin printrvg command. This argument is optional when only one secondary is configured.
# vradmin -g diskgroup -l repstatus local_rvgname
The output resembles:
