Restrictions for Volume Migration
Volume Migration must be used within the following restrictions:
• ShadowImage (HOMRCF). The operation for the volume migration
must be operated at the "SMPL" or "PAIR" or "COPY" state. If not,
paircreate -m cc command is rejected with EX_CMDRJE or EX_CMDIOE.
Also ShadowImage cannot be operated to CC_SVOL moving in Volume
Migration. In copying CC_SVOL, the copy operation for the volume
migration is stopped, if the ShadowImage pairsplit command is
executed.
• TrueCopy (HORC). The operation for the volume migration must be
performed at the "SMPL" or "PSUS" state. If not, paircreate -m cc
command is rejected with EX_CMDRJE or EX_CMDIOE. Also HORC cannot
be operated to CC_SVOL copying in Volume Migration. On one hand, in
copying CC_SVOL, the copy operation for the volume migration is
stopped, if pairresync command for of HORC is executed.
