Appendix A Parameter List
A.3 Volume Management
• FTSP Priority
Description
Input condition/
Display contents
Select either "Automatic" or the FTSP number that belongs to the migration destination
FTRP for the FTSP number to which priority is given.
When FTRP is not selected from the migration destination list, only "Automatic" is
displayed as the available option. If FTRP is specified, "Automatic" and the FTSP numbers
that belong to the migration destination FTRP are displayed. If "FTSP number" is selected
and the specified FTRP is changed, the "FTSP Priority" setting returns to the default value
("Automatic").
"FTSP Priority" indicates the FTSP number to which priority is given for allocating physical
capacity as the volume migration destination when multiple FTSPs exist in the migration
destination FTRP.
When "Automatic" is selected, the physical area is allocated to an FTSP for which the
drive type is "Online". If no free space exists in "Online" type disks and migration is not
available, the physical area is allocated to an FTSP for which the drive type is "Nearline".
If "Nearline" is also not available for migration, the physical area is allocated to an FTSP
for which the drive type is "SSD". Migration to an FTRP cannot be performed if "SSD" is not
available for migration. "Online SED" type FTSPs are used as "Online" type FTSPs. Also,
"Nearline SED" type FTSPs are used as "Nearline" type FTSPs and "SSD SED" type FTSPs are
used as "SSD" type FTSPs.
When "FTSP number" is selected, the physical area is allocated to the selected FTSP. If
there is no free space in the selected FTSP and migration is not available, the migration
destination FTSP number is determined as having the same priority ("Online" 
"Nearline"  "SSD") as when "Automatic" is selected.
The drive type for FTSPs can be checked from the [Flexible Tier Pool Detail] screen
(Flexible Tier Sub Pool). Refer to [Flexible Tier Pool Detail] screen (Flexible Tier Sub
Pool) in "ETERNUS Web GUI User's Guide (Operation)" for details.
