createmigration
DESCRIPTION
The createmigration command performs preparation phase of a migration. Actual data transfer will not be triggered by this command. This does following for a given set of source volumes while presenting to 3PAR destination storage system.
NOTE: Can only create one migration at a time per source EMC Storage system.
NOTE: Be aware, the createmigration command may take several minutes to complete.
NOTE: The volume(s) or host specified in the createmigration command are mapped to a storage group on the associated source EMC Storage system. All LUNs and all hosts in the mapped storage group will be migrated even if only a subset are entered in the createmigration command.

srcvolmap or volmapfile | A combination of commands is | Map that provides information about |

| used. | It can also have mapping of every |

| If srcvolmap is there, srchost should | source volume to required provisioning |
| not be there. | or destination CPG. This is required if |
| If srcvolmap has CPG and Prov | destCPG and destProv are not |
| provided. | |
| information, then destcpg and | |
| ||
| destprov need not be there. | |
| If the srcvolmap has mixed Prov | desired destination provisioning after |
| migration (Thin/Full), desired | |
| information ("thin" and "full") for some | |
| volumes, then destprov is | destination CPG name},{...},...] |
| Sample content of volmapfile: | |
| mandatory for the rest of the volumes | |
| not specified in srcvolmap. | “vdisk4”,thin,cpg1 |
|
| “vdisk2”,full,cpg2 |
|
| A provisioning and CPG entry here will |
|
| override default in destcpg and |
|
| destprov. |
|
| Possibilities: |
|
| “vdisk”,thin |
|
| “vdisk”,cpg |
|
| “vdisk” |
|
| “vdisk”,thin,cpg |
|
| For VMAX, use the following format: |
|
| Volume <device id> |
|
| The <device id> value must be five |
|
| characters in length. If the actual device |
|
| ID is less than five characters, add “0” |
|
| at the front to make five characters. For |
|
| example, if the VMAX device ID is |
|
| 0192: |
