Specifying redundant mover service partitions for a partition mobility operation

You can specify redundant mover service partitions (MSPs) for a partition mobility operation by using the Hardware Management Console (HMC) command-line interface.

About this task

Procedure

  1. To specify the redundant MSP for a single partition mobility operation, run the following command from the HMC command line:
    migrlpar -o v -m <srcCecName> -t <dstCecName> -p <lparName> 
    --redundantmsps <redundantmspOptionValue> -i "redundant_msps
    =<group_id>/<src_msp_name>/<src_msp_id>/<src_msp_ipaddr>/<dst_msp_name>
    /<dst_msp_id/dst_msp_ipaddr>,<group_id>/<src_msp_name>/<src_msp_id>/
    <src_msp_ipaddr>/<dst_msp_name>/<dst_msp_id/dst_msp_ipaddr>"  
    
    Note: You must specify the same value twice for the group_id variable, once for the primary MSP and the second time for the secondary MSP.
    The redundantmspOptionValue parameter can have one of the following values:
    • 0 when the partition mobility operation must not use redundant MSPs.
    • 1 when the partition mobility operation must use redundant MSPs. If redundant MSPs are not available, the partition mobility operation fails.
    • 2 when the partition mobility operation must use redundant MSPs if they are available.
  2. For multiple migration operations, run the following command from the HMC command line:
    migrlpar -o v -m <srcCecName> -t <dstCecName> -p <lparName_1>,
    ...,<lparName_2>,...,<lparName_n> --redundantmsps <redundantmspOptionValue> -i 
    "redundant_msps=<group_id>/<src_msp_name>/<src_msp_id>/<src_msp_ipaddr>/
    <dst_msp_name>/<dst_msp_id/dst_msp_ipaddr>,<group_id>/<src_msp_name>/<src_msp_id>/
    <src_msp_ipaddr>/<dst_msp_name>/<dst_msp_id/dst_msp_ipaddr>  
    
    Note: You can specify multiple values for the group_id variable, but each group_id variable must be specified twice, once for the primary MSP and the second time for the secondary MSP. For example, consider two different values for the group_id variable, 1 and 2. The group_id variable with a value 1 specifies two pairs of redundant MSPs, and the group_id variable with a value 2 specifies another two pairs of redundant MSPs. This example indicates that more than four MSPs are configured on the source and destination servers.
    The redundantmspOptionValue parameter can have one of the following values:
    • 0 when the partition mobility operation must not use redundant MSPs.
    • 1 when the partition mobility operation must use redundant MSPs. If redundant MSPs are not available, the partition mobility operation fails.
    • 2 when the partition mobility operation must use redundant MSPs if they are available.
    When you do not want to use redundant MSPs for partition mobility operations, run the following command from the HMC command line:
    migrlpar -o v -m <srcCecName> -t <dstCecName> -p 
    <lparName> --redundantmsps 0 -i "source_msp_name=<srcMspName>,
    source_msp_ipaddr=<srcMspIp>,dest_msp_name=<dstMspName>,dest_msp_ipaddr=<dstMspIp>"   
    
    The --redundantmsps 0 option forces the HMC not to use redundant MSPs, and a single MSP pair is used for the partition mobility operation.
