7.1.5 Flexible Tier Pool (Basic Information)
This function shows the list of Flexible Tier Pools (FTRPs).
• To use the Flexible Tier function (auto storage layering), the following operations are required:
- Registering the license for the Thin Provisioning feature is required to use the Thin Provisioning
function. To check the registration status of the license, refer to "7.1.4 License (Thin Provisioning)"
(page 206).
- Register the Optimization option for ETERNUS SF Storage Cruiser.
- Create the Flexible Tier Pools (FTRPs), Flexible Tier Sub Pools (FTSPs), and the Flexible Tier Volumes
(FTVs), using the ETERNUS SF Storage Cruiser.
• When " Attention" or " Warning" is displayed in "Used Status" in the FTRP list, the FTRP used
capacity exceeds the threshold. Immediately add drives and 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 used capacity).
• If the target FTRP does not exist when displaying the details screen, a message, " Target is Not Found."
is displayed.
• The required policy for the [Format Flexible Tier Pool (All Area)] function and the [Format Flexible Tier
Pool (Unformatted Area)] function is changed from "RAID Group Management" to "Maintenance
Operation" with controller firmware V10L40. To format the Flexible Tier Pool with an ETERNUS DX Disk
storage system that has controller firmware version V10L40 or later, ask a maintenance engineer who has
the "Maintenance Operation" policy.
This function displays a basic FTRP information, a list of FTSPs which belong to the FTRP, a list of RAID groups
which configure the FTSP, and a list of FTVs which have been registered to the FTRP.
