Thin Provisioning Pool (Basic Information)

Overview

This function shows the list of Thin Provisioning Pools (TPPs).

Caution

  • 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.

Note

  • 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.
