Select a device unit and then select [Design] - [AffinityGroup Operation] from the menu or [AffinityGroup Operation] from the pop-up menu to start the AffinityGroup operation window.The AffinityGroup operation window is shown below.AffinityGroup cannot be operated by ETERNUS3000, ETERNUS6000, ETERNUS4000 models 80 and 100.
Setting AffinityGroup in the Storage will allow it to set an access path by access path management functions. For access path management, see "6.3 Access Path Management"
The following are descriptions of the configuration of the AffinityGroup operation window.
A LogicalVolume view is displayed that is configured in the device unit selected at start-up of the Affinity operation window
RAIDGroup numbers are displayed. RAIDGroups to which LogicalVolumes are not allocated are not displayed.
TPP numbers are displayed. TPP to which LogicalVolumes are not allocated are not displayed.
A LogicalVolume numbers is displayed by RAIDGroup.
To a LogicalVolume to which LUN concatenation is executed is displayed [(Serial number/LogicalVolume concatenated total number)], following the LogicalVolume number.
Example
When 0x0008(1/2) is displayed:
LogicalVolume Number is 0x0008, a serial number is 1 and LogicalVolume concatenated total number is 2.
The capacity of LogicalVolume is displayed. The unit is MB.
Depending on the allocation to AffinityGroups, font colors vary as follows.
Font color | Meaning |
|---|---|
Black | Allocated |
Blue | Unallocated |
Orange | Allocated to multiple AffinityGroups or to LUNMapping. (shared with LogicalVolume) |
A LogicalVolume to which LUN concatenation is executed is shown in [relevant amount/totoal amount].
The views of AffinityGroups and LUNMappings are displayed that are configured in the device unit selected at start-up of the AffinityGroup operation window.
AffinityGroup numbers are displayed in decimal. If AffinityGroups are concatenated, all the numbers of concatenated AffinityGroups are displayed set off with commas.
For LUNMappings, port names are displayed.
Aliases of AffinityGroups and LUNMappings are displayed.
A LUN number allocated to the LogicalVolume in a LogicalVolume view in the same row is displayed in decimal by AffinityGroup and by LUNMapping.
The cell color changes as follows depending on the relevant LogicalVolume state.
Cell color | Meaning |
|---|---|
White | LUN number is editable. Also, a relevant LogicalVolume is not allocated to multiple AffinityGroups or LUNMappings (Multiple LUN numbers are not allocated). |
Yellow | LUN number is editable. Also, a relevant LogicalVolume is allocated to multiple AffinityGroups or LUNMappings (Multiple LUN numbers are Allocated). |
Gray | LUN number is not editable. If a LUN number falls under the following, it is not editable.

The following are descriptions of operation procedures of the AffinityGroup operation window.
Press the <AffinityGroup addition> button on the AffinityGroup operation window.
Then, the AffinityGroup add dialog is displayed. Enter a group number and a group name. Group names are optional.
Press the <OK> button.
Once the maximum number of AffinityGroups has been created no more can be added.
If you want to allocate a LUN (or change a LUN number), focus on a cell at which a row of LogicalVolume and a column of AfiinityGroup are intersected.
Enter the LUN number you want to allocate.
Select multiple cells to which you want to allocate LUNs and at which multiple rows of LogicalVolume and multiple columns of AffinityGroup are intersected.
Select [Automatic allocation] from the pop-up menu displayed by right click of mouse.
For automatic allocation of LUN, LUN numbers are allocated in ascending order from the smallest LUN number that is not allocated in the relevant AffinityGroup.
Focus on a cell to which you want to unallocated a LUN and at which a row of LogicalVolume and a column of AffinityGroup are instersected.
Press the delete key or the backspace key.
You cannot create any AffinityGroup without LUN.
Drag multiple cells to which you want to unallocated LUNs and at which multiple rows of LogicalVolume and multiple columns of AffinityGroup are intersected.
Select [Unallocation] from the pop-up menu displayed by right click of mouse.
You cannot create any AffinityGroup without LUN.
Press the <AffinityGroup edit> button with an AffinityGroup number or an AffinityGroup name you want to change selected. Or, select [AffinityGroup edit] from the pop-up menu.
Then the AffinityGroup change dialog is displayed. Enter a desired group number and a desired group name.
Press the <OK> button.
In the following case, AffinityGroup number is not changeable.
AffinityGroup to which a host affinity is set.
In the following cases, AffinityGroup numbers and AffinityGroup names are not changeable.
AffinityGroup to which a LogicalVolume is allocated that is allocated to an unsupported RAIDGroup.
AffinityGroup to which an unsupported LogicalVolume is allocated.
Concatenated AffinityGroup.
LUNMapping
Press the <AffinityGroup deletion> button with an AffinityGroup number or an AffinityGroup name you want to delete selected. Or select [AffinityGroup deletion] from the pop-up menu.
Then the confirmation dialog to delete AffinityGroup is displayed. If it is all right, press the <OK> button.
In the following cases, AffinityGroups cannot be deleted.
AffinityGroup to which a LogicalVolume that is allocated to an unsupported RAIDGroup is allocated.
AffinityGroup to which an unsupported LogicalVolume is allocated.
Concatenated AffinityGroup
AffinityGroup to which a host affinity is set.
LUNMapping
If you want to reflect created or corrected contents to the design window, press the <Execution> button.
Whenever the <Execution> button is pressed on the design window after the AffinityGroup operation window exits, the Return/Redo commands are executable.
To exit the AffinityGroup operation window, press the <End> button. If the <End> button is pressed before the <Execution> button, created or corrected contents are not reflected to the design window but the window exits.
