For more information about storing snapshot data by splitting pairs, see Splitting Fast Snap pairs to
store snapshot data on page 120.
• Split the Fast Snap pair within the consistency group using consistency group pair-split. Complete one
of the following:
◦ If you are not sharing Fast Snap P-VOLs with Continuous Access Journal or Continuous Access
Synchronous S-VOLs within a storage system, see Workflow for storing snapshot data or clone
pairs in consistency groups on page 121.
◦ If you are sharing Fast Snap P-VOLs with Continuous Access Journal or Continuous Access
Synchronous S-VOLs within a storage system, see Using consistency group pair-split with
shared volumes on page 122.
Splitting Fast Snap pairs to store snapshot data
A maximum of 1,024 snapshots can be stored or pairs can be cloned from a P-VOL. If you reach the
maximum, delete the unneeded or unused snapshots.
NOTE: If the amount of snapshot data in selected P-VOLs or the total number of pairs in selected
snapshot groups exceeds 37,768, an error message appears when attempting to perform pair tasks.
Prerequisites
• You must have the Storage Administrator (Local Copy) role.
• The Fast Snap pair status must be "PAIR".
• In RAID Manager, use the
raidcom add snap
command.
