setrcopygroup
InForm OS Version 2.3.1 Remote Copy User’s Guide
■ The reverse value of the <dr_operation> is not to be used as part of the normal
disaster recovery process.
EXAMPLES
The following example sets the group policy for Group1:
The following example reverses the current direction of secondary group
Group1 on InServ2
(the secondary system) so that I/O might be applied to the group after disaster recovery:
The following example sets
Group1 to be automatically synchronized every 30 minutes to
InServ2:
NOTES
■ An earlier version of this command provided a target subcommand. This subcommand
was deprecated in InForm OS release 2.2.3.
■ Reversing the direction of primary volumes will result in the loss of any data changed after
the group was stopped.
■ There is no default resynchronization period. For groups whose mode is asynchronous
periodic, you must specify a resynchronization period using
setrcopygroup period
<value>
or resynchronizations will not automatically take place.
■ The minimum interval for periodic resynchronizations is five minutes.
■ If the mirror_config policy is set for this group's target and the group is a primary
group, then the setrcopygroup command will be mirrored to the target when the
period and pol subcommands are used.
■ Use the -nosnap option when the primary server has failed or where the disks are ruined
or in an unknown state. For example, an uncontrolled shutdown can result in loss of data. If
you suspect that the primary volumes are not in a known good state, you should use this
option to force a FULL RESYNC when the primary system is restored.
