1. If you use RWC to share the volume with other software applications, the pair status determines
whether you can share the volume.
2. To share the volume with other software applications, you must use RAID Manager.
3. You cannot use Quick Restore.
4. Use the Data Retention to set this attribute.
5. RAID Manager is required to set this attribute. For setting the attribute, use the
raidvchkset -vg
command.
6. Use the Data Retention or use the
raidvchkdsp -v gfalg
command to confirm whether this
attribute is set to volume.
7. Can be shared if the pair is cascaded or has the clone attribute.
8. Can be set on an S-VOL of a cascaded pair or a clone attribute pair. Note that only the clone attribute
enables capacity saving.
Sharing Fast Snap volumes that have Data Retention access attributes
Depending on access attributes of the P-VOL, S-VOL, or pool volume, you cannot perform some pair
tasks and pool tasks with Fast Snap. The Fast Snap pair tasks you can perform are different depending
on whether you assign Data Retention access attributes using RAID Manager or RWC. The tables below
explain whether you can perform Fast Snap pair tasks and pool tasks on volumes that have access
attributes assigned by Data Retention. If you release assignment of snapshot data after assigning access
attributes to a Fast Snap S-VOL, the Fast Snap tasks you can perform are the same as those that can be
performed when the Read/Write attribute is assigned to the S-VOL.
Also, you can assign access attributes to Fast Snap P-VOL and S-VOLs. The tables below also explain
Fast Snap pair tasks and pool tasks after access attributes are assigned.
Access attributes and supported Fast Snap pair tasks
The following table lists the relationship between P-VOL and S-VOL access attributes and Fast Snap pair
tasks when using RWC to assign Data Retention access attributes.
