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.

Possibilities:

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:

 

 

createmigration -sourceuid

 

 

50000972C012F400 -srcvolmap

 

 

[{"Volume 00192"}] -destcpg
