To control the access to a volume, assign an access attribute to each volume. One of the following
access attributes can be assigned to each logical volume:
Read/Write
If a logical volume has the Read/Write attribute, hosts can perform both read and write operations
on the logical volume.
All volumes have the Read/Write attribute by default.
Read Only
If a logical volume has the Read Only attribute, hosts can perform read operations but cannot
perform write operations on the logical volume.
Protect
If a logical volume has the Protect attribute, hosts cannot access the logical volume. Hosts cannot
perform either read nor write operations on the logical volume.
Assigning access attribute
You can assign access attributes to volumes by using Volume Retention.
CAUTION:
Do not perform Volume Retention operations if any other program product is running.
