Specification method: "0x" is not added on top of the value.

Decimal numbers can be used only when the source LUN is from "0" to "255".

Input a decimal number

Specification method: "0x" is not added on top of the value.

Input a hexadecimal number (4-digit)

Specification method: Add "0x" on top of the value. Input in the "0xYYYY" format.

Operation Mode

OPEMODE Description
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

  • Host access to the destination storage system must be stopped when "Migration + Full Compare" is specified.

  • When "Migration + Full Compare" is specified for the operation mode, the time to complete the operation after data migration is increased significantly.

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

  • Host access to the destination storage system must be stopped when "Full Compare" is specified.

  • When "Full Compare" is specified for the operation mode, the time to complete the operation after data migration is increased significantly.

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).

Coding Conventions for the Storage Migration Setting File

Keyword Coding conventions

Common

  • The Storage Migration setting file must be saved in the text format.

  • Contents of the file must be described in alphanumeric characters.

  • A keyword (Type, GROUP, OPEMODE, PATH, VOL) and its setting value must be connected with "=" (equal).

  • Only a tab or space can be placed before a keyword (Type, GROUP, OPEMODE, PATH, VOL).

  • The number of setting values assigned to a keyword (Type, GROUP, OPEMODE, PATH, VOL) with "=" must coincide with the number specified for each keyword. For more information on the number of setting values for each keyword, refer to "Template File for Storage Migration Settings".

  • Add the following information for each GROUP.

    • For the ETERNUS DX900 S5 or the ETERNUS DX8900 S4

      PATH (CEx, CMy, CAz, Pw, WWN), VOL

    • For the other models

      PATH (CMy, CAz, Pw, WWN), VOL

  • There must not be an overlap with the content of the Storage Migration setting file or the migration information (GROUP, destination CA port, source WWN, source LUN, or destination volume) of the path already configured.

GROUP

OPEMODE

  • Specify "M", "M+QC", "M+FC", "QC", "FC", or "M & IO" for each GROUP (when OPEMODE is omitted, it is regarded as though "M" is specified and only migration is performed).

  • OPEMODE in the Storage Migration setting file must be only "M & IO" or options other than "M & IO"

  • For the setting range for each OPEMODE, refer to "Template File for Storage Migration Settings".

PATH

  • Enclose the PATH and VOL for each GROUP with "{ }" (bracket symbols).

  • Describe all "PATHs" and then all "VOLs" for each GROUP.

  • Up to 8 PATHs per GROUP can be specified.

  • Separate the PATH setting values with "," (comma).

  • For the setting range of PATH, refer to "Template File for Storage Migration Settings".

  • Describe the PATH in the following order.

  • If the migration destination is the ETERNUS DX900 S5 or the ETERNUS DX8900 S4, "CEx" must be specified when specifying a CE other than "CE0".

    If "CEx" is omitted, "CE0" is assumed.

  • For the other models, omit the "CEx" setting or specify "CE0".

  • Start a new line for each PATH. Multiple PATHs cannot be described without breaking.

VOL

  • Keep the number of VOLs to 512 or less, so they can be accessed from the source FC-CA port.

  • Separate the VOL setting values with "," (comma).

  • For the setting range of VOL, refer to "Template File for Storage Migration Settings".

  • Describe the VOL in the following order.

  • Start a new line for each VOL. Multiple VOLs cannot be described without breaking.

  • There must be no overlaps within the same GROUP for the source LUN.

Other Information

  • Entered letters are not case-sensitive.

  • A line that starts with "#" is a comment.

  • A file name can be any text string.

  • Spaces and tabs at the end of the line are not recognized as characters.

A setting example of the Storage Migration setting file is shown below:
