Displays RAID type of logical disk in any of the following at “RAID” column.
“0”: RAID 0
“1”: RAID 1
“5”: RAID 5
“6”: RAID 6
“10”: RAID 10
“50”: RAID 50
(vi) Capacity
Displays the capacity of logical disk in Gigabyte units (1G byte=1,073,741,824 bytes) to 1 decimal place.
(Truncate less than 2 decimal places. However, displays 0 byte to 100 Megabyte in 0.1).
(vii) RPL Type
Displays the replication type of logical disk in any of the following at “RPL Type” column. This column does
not appear when none of DynamicDataReplication and RemoteDataReplication is purchased.
IV: Not used as a replication volume
MV: Used as a replication source volume
RV: Used as a replication destination volume
RV/MV: Used as both RV and MV
(Blank): Cannot be used as a replication volume
(viii) Snapshot Type
Displays the snapshot type.
If you do not buy DynamicSnapVolume, this is not displayed.
Blank: Volume not used by snapshot
BV: Base volume (original volume from which copies are made)
SV: Snapshot volume (volume as the snapshot generation)
LV: Link volume (virtual volume establishing connection with BV or SV and implementing indirect access)
SDV: Snapshot data volume (logical disk configuring snapshot reserve area (SRA))
SV*: A type of snapshot volumes (volume that is not the snapshot generation)
* SV* may exist due to an iSM abnormal end and the like, however it cannot be reused. Therefore, free it
immediately by “Freeing Logical Disk” of configuration setting.
(ix) Link
Displays the connection state between BV-LV or SV-LV.
If you do not buy DynamicSnapVolume, this is not displayed.
(x) Group
Displays the group to which a logical disk belongs in any of the following at “Group” column. This column does
not appear when AccessControl and ReallocationControl are not purchased.
Preserve: Preserve group
Reserve: Reserve group
(Blank): Already assigned to the LD Set
