For details about the relocation progress rate, check the tier relocation log. For more information
about the table item for the tier relocation log file, see “Tier relocation log file contents”
(page 83).
• Pool Management Task (Status/Progress) on “View Pool Management Status window”
(page 293).
Displays the status of the pool management task being performed, each V-VOL progress ratio
in the pool and its average.
◦ Waiting for Relocation: The tier relocation process is being waited.
◦ Relocating: The tier relocation process is being performed.
For details about the relocation progress rate, check the tier relocation log. For more information
about the table item for the tier relocation log file, see “Tier relocation log file contents”
(page 83).
• Relocation Result on “Pools window after selecting pool (Pools window)” (page 242), “Top
window when selecting a pool under Pools” (page 247), and “View Pool Management Status
window” (page 293).
Displays the status of the tier relocation processing.
◦ In Progress: The status of Pool Management Task is Waiting for Relocation or Relocating.
◦ Completed: The tier relocation operation is not in progress, or the tier relocation is
complete.
◦ Uncompleted (n% relocated): The tier relocation is suspended at the indicated percentage
progression.
◦ -: The pool is not a Smart Tiers or Smart Tiers Z pool.
• Relocation Priority on “Top window when selecting a pool under Pools” (page 247) and “View
Pool Management Status window” (page 293).
Displays the relocation priority.
◦ Prioritized: The priority is set to V-VOL.
◦ Blank: The priority is not set to V-VOL.
◦ -: V-VOL is not the Smart Tiers Z V-VOL or the tier relocation function is disabled.
• Performance Graph on “View Tier Properties window” (page 284).
The performance graph for the available monitor information is displayed in the View Tier
Properties window.
Execution modes when using RAID Manager
Manual execution mode
In Manual execution mode, you can manually collect monitoring data and relocate a tier. You can
execute commands to do the following:
1. Start monitoring.
2. Stop monitoring.
3. Perform tier relocation.
The following illustrates tier relocation processing when in Manual execution mode:
