HTSM for MF

All

Known problems

Problems

The value of the total used capacity shown in HTSM for MF excludes the reserved capacity for a DP pool with Full Allocation enabled volumes. For this reason, note when checking the following values:

REXX variables

ISPF panels

- Total field on the Tiering Policy Group Summary panel.

- Total field on the Tiering Policy Group Volume List panel

- Total field in the Current Relocation Information area on the Tiering Policy Group Pool Status Detail panel.

The following value is also evaluated without including Reserved Capacity in overall Capacity for a DP pool with Full Allocation enabled volumes. 

- Pools exceeding threshold field on the Tiering Policy Group Summary panel.

You can check the used capacity and the reserved capacity on the Storage Navigator as follows.

- DP pool unit:

  Used and Reserved field on the Pools tab in the Pools window.

- DP volume unit:

  Used and Reserved field on the Virtual Volumes tab of the target pool.

You can check if the Full Allocation is enabled as follows.
