HP XP P9500 Storage - Manual (Page 76)

Keep the record, but delete the tiering policy parameters.
Before the change:
#TYPE ,DEVICE,TPGID,TierLvl,Entry,Reloc
STORGRP,SG1 ,TPG1 ,2 ,HIGH
DEVN ,1202 ,TPG1 ,2 ,HIGH
After the change:
#TYPE ,DEVICE,TPGID,TierLvl,Entry,Reloc
STORGRP,SG1 ,TPG1
DEVN ,1202 ,TPG1 ,2 ,HIGH
The above example changes the tiering policy of volumes in the storage system in the SMS storage
group SG1 back to the default.
TIP:
After you change the tiering policy back to the default, the status of the volume to delete is as
follows:
• Tiering policy level: 0
• New-page assignment tier: MIDDLE
• Whether to execute tier relocation: Y
CAUTION:
If the record (not the tiering policy parameters) is deleted, the volume is deleted from the tiering
policy group while the tiering policy remains. Consequently, Smart Manager for Mainframe
cannot manipulate the volume.
When deleting tiering policies assigned individually to volumes in the SMS storage group so that
they match the settings on the SMS storage group
