Check FS pair status.
For more information about checking FS pair status, see “Checking Fast Snap pair status”
(page 61) .
•
Create FS pairs.
For more information, see:
◦ “Workflow for creating and managing Fast Snap pairs” (page 62) .
◦ “Workflow for creating Fast Snap pairs using Remote Web Console” (page 62) .
◦ “Creating Fast Snap pairs and defining them in snapshot or consistency groups using the
RAID Manager” (page 63)
.
•
Split pairs to store snapshot data.
For more information, see:
◦ “Splitting Fast Snap pairs to store snapshot data” (page 73) .
◦ “Splitting Fast Snap pairs to store snapshot data using the RAID Manager” (page 75) .
◦ “Workflow for splitting Fast Snap pairs in consistency groups” (page 75) .
◦ (If you are sharing FS P-VOLs with Cnt Ac-J or Cnt Ac-S S-VOLs) “Workflow for consistency
group pair-split with shared volumes” (page 76) .

If the FS pair is defined in a consistency group, change the FS pair status.
For more information about changing pair status, see “Workflow for defining pairs to
consistency groups when the host is down” (page 72) .
