GROUP |
Specify a path group for each source storage system. Up to 16 path groups can be specified. Specify "0x" (2-digit) + 0 - F (1-digit) with hexadecimal numbers. (Example) GROUP=0x0 |

OPEMODE |
Specify one of the operation modes (M/M+QC/M+FC/QC/FC/M & IO) for the Storage Migration. The following symbols are used for the operation modes: M: Migration M+QC: Migration + Quick Compare M+FC: Migration + Full Compare QC: Quick Compare FC: Full Compare M & IO: Migration & Host IO OPEMODE can be omitted. When this parameter is not specified, "Migration" is used. Refer to "Operation Mode" for details. (Example) OPEMODE=M+QC |

PATH |
Specify the path information of the destination and source storage systems. Up to 8 paths per path group can be specified. (Example) For the ETERNUS DX900 S5 or the ETERNUS DX8900 S4 PATH=CEx,CMy,CAz,Pw,vvvvvvvvvvvvvvvv For the other models PATH=CMy,CAz,Pw,vvvvvvvvvvvvvvvv x: CE number, y: CM number, z: CA number, w: Port number vvvvvvvvvvvvvvvv: WWN |

WWN |
Specify the World Wide Name (WWN) of the source FC-CA port to which the path is configured. |
16-digit hexadecimal (using "0" as the first digit or using an "F (f)" for all 16 digits is not allowed) |
|||||||||
VOL |
Specify the source LUN (Y) and the destination volume (Z). The maximum number of source LUNs for each migration path (PATH) is 512. (Example) VOL=Y, Z Example of specifying source LUNs and destination volumes

Specification code | Meaning | |
M |
Migration |
Data migration from the source storage system to the destination storage system is performed (offline Storage Migration). |
M+QC |
Migration + Quick Compare |
Data migration from the source storage system to the destination storage system and a data comparison of source LUNs and destination volumes are performed. "Quick Compare" compares data in a part of the volume area. "Migration + Quick Compare" consecutively executes "data migration" and "data comparison" for each volume (offline Storage Migration). |
M+FC |
Migration + Full Compare |
Data migration from the source storage system to the destination storage system and a data comparison of source LUNs and destination volumes are performed. "Full Compare" compares data in entire volume area. "Migration + Full Compare" consecutively executes "data migration" and "data comparison" for each volume (offline Storage Migration). Caution
|
QC |
Quick Compare |
A data comparison of source LUNs and destination volumes is performed. "Quick Compare" compares data in a part of the volume area (offline Storage Migration). |
FC |
Full Compare |
A data comparison of source LUNs and destination volumes is performed. "Full Compare" compares data in entire volume area (offline Storage Migration). Caution
|
M & IO |
Migration & Host IO |
Data migration from the source storage system to the destination storage system is performed. Stop the operation only when switching the host connection to the destination storage system. This enables continued access from the host to the destination volume during the data migration (online Storage Migration). |
