HP Online Import Software manual Createmigration, Volume device id

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.

PARAMETERS

Parameter	Mandatory/Optional
sourceuid	Mandatory
srcvolmap or volmapfile	A combination of commands is
	mandatory as specified by user—for
	example, if srchost is used,
	destcpg and destprov should be
	used.
	If srcvolmap is there, srchost should
	not be there.
	If srcvolmap has CPG and Prov
	information, then destcpg and
	destprov need not be there.
	If the srcvolmap has mixed Prov
	information ("thin" and "full") for some
	volumes, then destprov is
	mandatory for the rest of the volumes
	not specified in srcvolmap.

Description

WWN (World Wide Name).

Map that provides information about the source volumes for migration. A list of volume names that identifies the volumes should be provided.

It can also have mapping of every source volume to required provisioning or destination CPG. This is required if destCPG and destProv are not provided.

-srcvolmap[{”source unique name”, desired destination provisioning after migration (Thin/Full), desired destination CPG name},{...},...]

Sample content of volmapfile:

“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:

createmigration -sourceuid 50000972C012F400 -srcvolmap [{"Volume 00192"}] -destcpg
