Relocation priority

You can use the relocation priority function to set the selection priority of a DP-VOL when performing relocation. With this setting, a prioritized DP-VOL can be relocated earlier during a relocation cycle. To set this function, use Device Manager - Storage Navigator . The function is activated after the monitoring data is collected.

For example, if LDEVs of LDEV IDs with LDEV#1, LDEV#2, LDEV#3, LDEV#4, and LDEV#5 are not given priority for relocation, LDEVs are relocated with the following sequences. In this example, three LDEVs are relocated in each period. The number of LDEVs to relocate can change by the relocation cycle or the data size.

Relocating cycle

Relocating sequence of LDEV#1 in each cycle

Relocating sequence of LDEV#2 in each cycle

Relocating sequence of LDEV#3 in each cycle

Relocating sequence of LDEV#4 in each cycle

Relocating sequence of LDEV#5 in each cycle
