Sharing volumes and Data Retention access attributes
You can create FS pairs using volumes on which you set Data Retention access attributes.
Access attributes and supported FS tasks
Depending on access attributes, you cannot perform some pair tasks and pool tasks with FS. The
FS 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
FS pair tasks and pool tasks on volumes that have access attributes assigned by Data Retention.
Also, you can assign access attributes to FS P-VOL and S-VOLs. The tables below also explain FS
pair tasks and pool tasks after access attributes are assigned.
The following table lists the relationship between P-VOL and S-VOL access attributes and FS pair
tasks when using RWC to assign Data Retention access attributes.
