In this example, group1 represents the group name in the CCI configuration definition file, and pair1 represents the name of the volume whose pair is the target volume of the operation.

CAUTION:
If any of the following operations is performed on Volume Migration source volume during migration, the volume migration process stops:
  • ShadowImage operation that changes the volume status to COPY(SP) or PSUS(SP).
  • Universal Replicator operation that changes the volume status to something other than PSUS
  • TrueCopy operation that changes the volume status to something other than PSUS/PSUE/PAIR
  • You must have the Storage Administrator (Provisioning) role to perform this task.
  • The volumes meet all requirements as source and target volume candidates.
  1. Start CCI.
  2. Type the following command for a SMPL pair to start volume migration:

    paircreate -g group1 -d pair1 -m cc -vl

    When volume migration starts, the status of the pair changes to COPY.

  3. Type the following command to check the status of the pair:

    pairdisplay –g group1 –d pair1 -fcex

    When volume migration completes, the status of the pair changes to PSUS. If volume migration fails, the status of the pair changes to PSUE.

  4. After the pair status is changed to PSUS or PSUE, type the following command to delete the pair:

    pairsplit –S –g group1 –d pair1

    Note:
    • If the migration fails (the status of the pair becomes PSUE) in step 3, repeat steps 2 to 4. When the alert message is displayed, check the alert message and recover the failure, and then repeat steps 2 to 4. If you are unable to change the pair status back to SMPL, contact the service engineer.
    • Entering the pairsplit -S command during volume migration interrupts volume migration.
