Thin Provisioning Pool (Basic Information)
Overview
This function shows the list of Thin Provisioning Pools (TPPs).
When using the Thin Provisioning function, "Enable" the Thin Provisioning. Refer to the [Set Thin Provisioning] function for details.
If the TPP usage exceeds the threshold, immediately add drives to expand the TPP capacity. The threshold can be checked in "Used Status" of the TPP list.
This function shows the TPP basic information, a list of the RAID groups that configure the TPP, and a list of the TPVs that are registered in the TPP.
To check whether the Thin Provisioning function is enabled or disabled, use the [Settings (Thin Provisioning)] function.
To check the threshold for monitoring the TPP used capacity, use the [Threshold (Thin Provisioning Pool)] function.
To check the Eco-mode setting that is specified for the TPP, use the [Eco-mode Schedule (Thin Provisioning)] function.
