Appendix D Notes on Use for Data Replication

*2: When the total capacity of logical disks is less than 0.1 GB, it is represented as 0.1 GB.
(2) S series (not including S400/S1400/S2400/S2800 and 3000/4000 series)
The user or the system engineer can bind logical disks of the disk arrays (except for
S400/S1400/S2400/S2800 and 3000/4000 series). The capacities of logical disks to be bound
vary depending on the RAID configuration.
If you want to bind logical disks which are to be used with DataReplication, the disks to be paired
must have the same capacity. If having purchased or planning to purchase the products such as
DataReplication, keep in mind that the following assists in easily updating the system
configuration later:
y Binding logical disks having the same capacity
y Selecting RAID configuration in which logical disks having the same capacity are easy to be
bound
iSM can also bind logical disks through the CLI (Command Line Interface). However use of
GUI is recommended. This appendix mainly explains how to bind logical disks through the GUI.
If use of DataReplication is not for binding logical disks, read the description of “RV”*1 as
“logical disks having the same capacity” in the explanation below.
A logical disk’s capacity smaller than 0.1GB*2 is shown rounded on the configuration setting
summary display*3. Note that different capacities may appear to be identical.
*1: RV (Replication Volume) is a copy volume in using DataReplication.
*2: iSM processes data with 1MB = 1024KB.
*3: When the total capacity of logical disks is less than 0.1 GB, it is represented as 0.1 GB.
