Operating System Software Owner manual

• over_per_alert - If a synchronization of a periodic Remote Copy group takes longer
to complete than its synchronization period, an alert will be generated. This is the default
behavior.
• no_over_per_alert - If a synchronization of a periodic Remote Copy group takes
longer to complete than its synchronization period then an alert will not be generated.
<dr_operation>
Specifies the operation of the group(s). Valid operations are:
• reverse - Reverses volume group roles. By itself, the reverse specifier does not change
the natural direction of data flow. The operation is mirrored resulting in a direction change
on both systems.
CAUTION: Do NOT use the reverse specifier as part of the disaster recovery process.
Misuse of this specifier can result in lost data on the system configured as the primary
system under normal operating conditions.
For information on using the reverse specifier as part of normal operations, see “Using
Tape for Initial Synchronization and Backup” (page 82)
• failover - Changes secondary volume groups to primary volume groups on the primary
system in the event of a system failure. If the group has multiple targets it will also attempt
to pull more recent data from other targets and start Remote Copy to those targets when
complete.
• recover - Used for groups on which the failover operation has already been run.
Changes matching primary volume groups on the backup system to secondary volume
groups and then starts and synchronizes all groups.
• restore - Used on groups on which the recover operation has already been run.
Returns all groups to their natural direction and starts them.
<group_name>
Specifies the name of the volume group whose policy is to be set, or whose target designation
is to be switched.
<target_name>
Specifies the target name for the target definition created with the creatercopytarget
command.
<period_value>s|m|h|d
Specifies the time period in units of seconds (s), minutes (m), hours (h), or days (d), for automatic
resynchronization (e.g. 14h for 14 hours). The time must be longer than or equal to five minutes
and not more than one year in duration, or set to zero to indicate that no period should be
used. This specifier can only be used with the period subcommand.
<mode_value>
Specifies the mode, sync or periodic, to which the group is set. This specifier can only be
used with the mode subcommand.
<pattern>
Specifies a glob-style pattern. If this specifier is not used, the <group_name> or
<target_name> specifier must be used. For more information, issue: clihelp sub,globpat
RESTRICTIONS
• This command requires the HP 3PAR Remote Copy Software license. Contact your local service
provider for further information.
• When issuing the setrcopygroup <dr_operation> command, either the <group_name>
specifier, the <target_name> specifier, or the <pattern> specifier must be specified.
• Reversing the direction of primary volumes will result in the loss of any data changed after
the group was stopped.
