Access attributes and supported HTI tasks

The following table lists the relationship between P-VOL and S-VOL access attributes and HTI pair tasks when using HDvM - SN to assign Data Retention Utility access attributes.


Volume access attributes specified for the HTI pair		HTI pair task
P-VOL	S-VOL	Create, split, suspend, Resync pair (Normal Copy)	Resync (Reverse Copy)¹	Delete
Read/Write	Read/Write	Yes
Read/Write	Read Only, Protect, S-VOL Disable	No
Read Only, Protect, S-VOL Disable	Read/Write	Yes	No	Yes
Read Only, Protect, S-VOL Disable	Read Only, Protect, S-VOL Disable	No
Reverse Copy does not copy S-VOL access attributes to P-VOLs (see Pair resynchronization methods).

The following table lists the relationship between P-VOL and S-VOL access attributes and HTI pair tasks when using CCI to assign Data Retention Utility access attributes.


Volume access attributes specified for the HTI pair		HTI pair task
P-VOL	S-VOL	Create, split, suspend, Resync pair (Normal Copy)	Resync (Reverse Copy)¹	Delete
Read/Write, Read Only, Protect	Read/Write, Read Only, Protect	Yes
Read/Write, Read Only, Protect	S-VOL Disable	No
S-VOL Disable	Read/Write, Read Only, Protect	Yes	No	Yes
S-VOL Disable	S-VOL Disable	No
Reverse Copy does not copy S-VOL access attributes to P-VOLs (see Pair resynchronization methods).

The following table lists the relationship between P-VOL and S-VOL access attributes specified by HTI and HTI pool tasks when using CCI or HDvM - SN to assign Data Retention Utility access attributes.


Volume access attributes specified by HTI				HTI pool task
Volume access attributes specified by HTI				Pool-VOL setting
Read/Write				Yes
Read Only				No
Protect				No
S-VOL Disable				No
Legend Yes: You can perform the task No: You cannot perform the task

Performing an HTI task does not change the volume access attributes.

The following table shows the HTI pair status that is required to use Data Retention Utility to assign access attributes to some HTI P-VOL and S-VOLs when using HDvM - SN to assign Data Retention Utility access attributes.
