Disabling compression

The vradmin set command allows you to disable compression on a per secondary host basis.

To disable compression

  1. Disable compression using the following command:
    # 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.

  2. Verify that compression has been disabled using the following command:
    # vradmin -g diskgroup -l repstatus local_rvgname

The output resembles:
