Expand Thin Provisioning Pool

This function expands the capacity of a Thin Provisioning Pool.
Refer to "The maximum number of pools and maximum pool capacity for each model" (page 559)
about the maximum number and capacity of pools for each model.
• TPP capacity is expanded in units of RAID groups. The specifications for a RAID group (such as the RAID
level, the drive type, and the number of member drives) that is to be added are the same as the existing
RAID group.
• TPP capacity cannot be expanded in the following conditions:
- When the maximum capacity of TPPs are already registered in the ETERNUS DX
- When resources for creating TPPs (such as the number of RAID groups and volumes) are insufficient
(When the maximum number of RAID groups or volumes already exists, TPP cannot be expanded)
• After a TPP capacity is expanded, the expanded area of TPP is formatted automatically. To check the
progress of formatting ("Progress", "Estimated Time Left", and "Remaining Size"), refer to "Thin
Provisioning Pool Detail (Basic)" in "ETERNUS Web GUI User's Guide (Operation)". Click the TPP name to
display the basic information.
• To check the current maximum pool capacity, refer to "Settings (Thin Provisioning)" in "ETERNUS Web GUI
User's Guide (Operation)".
• In the controller firmware versions V10L31 and earlier, "SED" indicates "Online SED".
