3.9 Start RAID Migration
*1: When the migration source is a TPV or an FTV, the capacity indicates used capacity (the physical capacity that is
allocated from a TPP or an FTRP).
*2: The maximum pool capacity is the maximum total capacity for TPPs and FTRPs that can be created in the ETER-
NUS DX. Refer to
• The encryption function cannot be used for the ETERNUS DX60 S3.
• To change the data protection method (Default/T10-DIF) for the migration destination, perform the
following procedure.
- Stop host access in advance.
- Reboot the server after the migration is complete.
• Migration cannot be performed under the following conditions:
- When the maximum number of volumes is already registered in the ETERNUS DX
- When a RAID group diagnosis or a disk diagnosis is being performed in the ETERNUS DX
- 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 migration, TPV balancing, and FTRP balancing (*1) processes that are
running in the ETERNUS DX exceed 32
- When the total capacity of the migration, TPV balancing, and FTRP balancing (*1) processes that are
running in the ETERNUS DX exceeds 128TB
*1: When the FTRP balancing is performed, the FTV balancing process starts in the FTSP. Refer to
Balancing Flexible Tier Pool" (page 587)
• A volume cannot be expanded when the type of migration source volume is "TPV" or the type of migration
destination is "TPP".
• A volume cannot be expanded when the type of migration source volume is "FTV" or the type of migration
destination is "FTRP".
• Even if the volume type is "Standard", the maximum ODX Buffer volume capacity is 1TB.
• A migration source volume and a migration destination volume that are undergoing migration cannot be
deleted.
• When performing migration for volumes for which "Cache Page Capacity" is changed using the procedure
in "3.14 Modify Cache Parameters" (page
value (unlimited).
• When the destination volume capacity is expanded by migration, the expanded volume capacity must be
recognized by the server after migration. Refer to the manuals of each OS or file system for information
about server operation.
• When "
TPP after migration, the used capacity of the relevant TPP is exceeding the threshold. In this case, expand
TPP capacity by using the procedure in
Provisioning Pool (Basic Information)" in "ETERNUS Web GUI User's Guide (Operation)" for TPP usage.
• When "
FTRP after migration, the used capacity of the relevant FTRP is exceeding the threshold. Use ETERNUS SF
Storage Cruiser to expand the capacity of the appropriate FTSP (for which expansion is determined to be
necessary based upon the performance and usage). Refer to "Flexible Tier Pool (Basic Information)" in
"ETERNUS Web GUI User's Guide (Operation)" for FTRP usage.
