For details on the parameters for this function, refer to "A.6.2 Create Thin Provisioning Pool" (page 923).
For the factory default settings for this function, refer to "Appendix B Create Thin Provisioning Pool" (page
1006).
There are two methods to create a TPP: automatic drive selection and manual drive selection.
• When creating TPP type volumes, "Enable" the Thin Provisioning function. Refer to "6.1 Set Thin
Provisioning" (page 557) for details.
• For the ETERNUS DX60 S3, SSDs and SEDs cannot be used for configuring a TPP.
• The encryption function cannot be used for the ETERNUS DX60 S3.
• For the ETERNUS DX60 S3, "High Reliability (RAID6-FR)" cannot be selected as the RAID level because the
controller firmware version for the ETERNUS DX60 S3 is V10L25.
• When encryption mode is disabled, TPP encrypted by CM cannot be created.
• Once a TPP has been created, the encryption status cannot be changed.
• TPPs cannot be created in the following conditions:
- When the maximum number of Thin Provisioning Pools are already registered in the ETERNUS DX
- When the maximum capacity of Thin Provisioning Pools are already registered in the ETERNUS DX
- When the resources for creating TPPs (such as the number of RAID groups, the number of volumes,
etc.) are insufficient
(When the maximum number of RAID groups or volumes already exists, TPPs cannot be created)
• After a TPP is created, the 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 expand the TPP capacity after a TPP is created, refer to "6.5 Expand Thin Provisioning Pool" (page 571)
.
• To rename the TPP after a TPP is created, refer to "6.4 Rename Thin Provisioning Pool" (page 569)
.
• To change the TPP threshold after a TPP is created, refer to "6.8 Modify Threshold Thin Provisioning Pool"
(page 580).
• To check the current maximum pool capacity, refer to "Settings (Thin Provisioning Pool)" in "ETERNUS Web
GUI User’s Guide (Operation)".
• In the controller firmware versions V10L31 and earlier, "SED" indicates "Online SED".
