pairsplit
The pairsplit command is used to split volume pairs. This command stops updates to the secondary
volume of a pair and can either maintain (status = PSUS) or delete (status = SMPL) the pairing
status of the volumes. The pairsplit command can be applied to a paired logical volume or a group
of paired volumes. The pairsplit command allows read access or read/write access to the secondary
volume, depending on the selected options. When the pairsplit command is specified, acceptance
of write requests to the primary volume depends on the fence level of the pair (data, status, never,
or async). When you use Auto LUN, you can only execute the -S option because the other options
are rejected. Enterprise storage systems and Unified Storage VM do not support the -ms
<Split-Maker> option and the -mscas <Split-Maker> [mun#] option.
