migratelp Command

Purpose

Moves allocated logical partition from one physical partition to another physical partition on a different physical volume.

Syntax

migratelp LVname/LPartnumber[ /Copynumber ] DestPV[/PPartNumber]

Description

The migratelp moves the specified logical partition LPartnumber of the logical volume LVname to the DestPV physical volume. If the destination physical partition PPartNumber is specified it will be used, otherwise a destination partition is selected using the intra region policy of the logical volume. By default the first mirror copy of the logical partition in question is migrated. A value of 1, 2 or 3 can be specified for Copynumber to migrate a particular mirror copy.

Note:
  1. You must consider the partition usage, reported by lvmstat, on the other active concurrent nodes in case of a concurrent volume group.
  2. Strictness and upper bound settings are not enforced when using migratelp.
  3. Running this command on an active, firmware-assisted, dump logical volume temporarily changes the location of the dump device to /dev/sysdumpnull. After you have successfully migrated the logical volume, this command calls the following command to set the firmware-assisted, dump logical volume to the original logical volume. 
    sysdumpdev -P

The migratelp command fails to migrate partitions of striped logical volumes.
