This example deletes the record of the volume from the tiering policy information CSV file.
After the record is deleted, the tiering policies assigned individually are deleted. The tiering
policies that are set to the SMS storage group where the volume belongs are applied.
Before the change:

#TYPE ,DEVICE,TPGID,TierLvl,Entry,Reloc

STORGRP,SG1 ,TPG1 ,2 ,HIGH

DEVN ,1101 ,TPG1 ,1

DEVN ,1202 ,TPG1 ,2 ,HIGH

After the change:

#TYPE ,DEVICE,TPGID,TierLvl,Entry,Reloc

STORGRP,SG1 ,TPG1 ,2 ,HIGH

DEVN ,1202 ,TPG1 ,2 ,HIGH

In the above example, the tiering policy level of the volume of device number 1101 in the
SMS storage group SG1 is 2. The new-page assignment tier is HIGH.

Update the tiering policy group definition file to the new definition.

CALL KTLOAD "STEM(stem1.) MSG(msgstem.) PREFIX(PREFIX1)",

"TPG(TPG1)";

CALL KTACTTPG "STEM(stem1.) MSG(msgstem.)";

Confirm that the updates are applied to the storage system.

CALL KTLOAD "STEM(stem1.) MSG(msgstem.) PREFIX(PREFIX1)",

"TPG(TPG1)";

CALL KTQRYTPG "STEM(stem1.) MSG(msgstem.)";
