– Capacity: The capacity of the volume. If the volume is thin-provisioned or compressed, this number is the virtual capacity. 

– IOPS Limit: The maximum rate at which the volume processes the I/O operations in IOPS, in case you set I/O throttling for the volume. Disabled means there is no IOPS I/O throttling enabled for the volume. 

– Bandwidth Limit: The maximum rate at which the volume processes the I/O operations in MBps, in case you set I/O throttling for the volume. Disabled means there is no bandwidth I/O throttling enabled for the volume. 

– Encrypted: Whether the volume is encrypted. 

– FlashCopy Mappings: The number of existing FlashCopy relationships. For more information, see Chapter 10, “Copy Services” on page 465. 

– Mirror sync rate: The ratio that determines how quickly the copies of the volume are synchronized. It also affects the format process speed. Be default, this rate is set to 50; 0 means no synchronization occurs. 

– Cache mode: Whether the cache is enabled or disabled for this volume. 

– Cache state: Whether open I/O requests are in the cache that is not destaged to the disks. 

– UDID (OpenVMS): The unit device identifiers (UDIDs) that are used by OpenVMS hosts to access the volume. 

– Volume UID: The volume unique identifier. 

– I/O Group: The volume caching I/O group and the I/O groups that the host can use to access the volume. 

– Preferred node: The ID of the preferred node for the volume.
