CAUTION: If any of the following operations are performed on an XP Auto LUN source
volume during migration, the volume migration process stops:
◦ Compatible XRC operation
◦ Concurrent Copy (CC) operation
◦ TrueCopy for Mainframe operation that changes the volume status to something other
than suspended or simplex
◦ XP Continuous Access operation that changes the volume status to something other than
PSUS, PSUE, or SMPL
◦ XP Continuous Access Journal operation or Universal Replicator for Mainframe operation
that changes the volume status to COPY
◦ ShadowImage for Mainframe operation that changes the volume status to SP-Pend or
V-Split
◦ XP Business Copy operation that changes the volume status to COPY(SP) or PSUS(SP)
◦ XP Continuous Access Journal operation or Universal Replicator for Mainframe operation
XP Thin Provisioning: If some XP Thin Provisioning virtual volumes related to one pool are used
as a source volume, the other XP Thin Provisioning virtual volume related to the same pool
cannot be specified as the target volume.
•
Expanded LUs as source volumes. To specify an expanded LU as a source volume for migration,
you can specify individual LDEVs within the expanded LU (for example, LDEVs with high
usage), and XP Auto LUN will migrate only the specified LDEVs. If desired, you can also specify
all LDEVs of the expanded LU to relocate the entire expanded LU. In this case, you must make
sure that the required reserved target LDEVs are available.
•
Target volumes. Target volumes must be reserved prior to migration using the XP Auto LUN
software. Hosts cannot access reserved volumes.
The following volumes cannot be reserved as target volumes:
◦ Expanded LUs
◦ Volumes that are set as command devices (devices reserved for use by the host)
◦ Volumes that are assigned to XP Business Copy or XP Continuous Access pairs
◦ Volumes that are used by the Compatible XRC host software function
NOTE: If the status of a Compatible XRC volume is suspended because the session was
canceled, the volume can be used as a source volume.
◦ Volumes that are used by the IBM 3990 Concurrent Copy (CC) host software function
◦ Volumes that are reserved for XP Business Copy operations
◦ Volumes that have Cache Residency Manager data or Cache Residency Manager for
Mainframe data stored in cache
◦ Volumes used by XP Continuous Access Journal or Universal Replicator for Mainframe as
a data volume or journal volume
◦ Volumes in which Volume Retention Manager specified the Read Only or Protect attribute
◦ Volumes with Volume Security disabled to be used as secondary volumes
◦ Volumes that Data Retention Utility specified the Read Only or Protect attribute, or disabled
to be used as secondary volumes
◦ Volumes that are reserved by a migration program other than XP Auto LUN
