• Standard volumes, SDVs, or SDPVs are registered in the RAID group or the RAID group is
not being used
• The RAID group does not belong to a TPP
• The RAID group is not registered as a REC Disk Buffer
• The status of the RAID group is "Available" or "Present"
• The RAID group must not be blocked
• The free space of the RAID group is more than the capacity of the migration source volume
(*1)
• The RAID group is not the same RAID group as the RAID group to which the migration source
volume belongs
• LDE is not being performed in the target RAID group
*1: When the migration source is a TPV, the capacity indicates used capacity (the physical capacity
that is allocated from a TPP)
Requirements for a migration destination TPP:
• The "Status" is "Available"
• The capacity of the TPP is more than the capacity of the migration source volume (*1)
• The capacity of the migration source volume is less than the maximum TPP capacity for each
model
• The TPP is not the same as the TPP to which the migration source volume belongs
*1: When the migration source is a TPV, the capacity indicates used capacity (the physical capacity
that is allocated from a TPP)
Model per RAID group per ETERNUS DX Disk
storage system
ETERNUS DX80 S2 Up to 128 Up to 2048
ETERNUS DX90 S2 Up to 128 Up to 4096
ETERNUS DX410 S2/DX440 S2 Up to 128 Up to 16384
• Migration cannot be performed under the following conditions:
- When the maximum number of volumes is already registered in the
ETERNUS DX Disk storage system
- When a RAID group diagnosis or a disk diagnosis is being performed
in the ETERNUS DX Disk storage system
- When the RAID group to which the migration source volume belongs
is blocked or failed
- When Advanced Copy is being performed by specifying the whole
volume in the migration source volume and the settings for the
volume capacity that is to be expanded are performed before and
after migration
- When the total number of migrations and TPV balancing processes
that are running in the ETERNUS DX Disk storage system exceed
32
- When the total capacity of the migration and TPV balancing
processes that are running in the ETERNUS DX Disk storage system
exceeds 128TB
