VVOL access path is the connection setting for the VMware host, FC switch, and the ETERNUS Disk storage system. The setting is necessary in order to recognize the created VVOL datastore in the VMware host.
The procedure to set a VVOL access path is as follows:
On the global navigation tab, click Storage.
On the Category pane, click VVOL Management.
The items of the Category pane change into the items concerning the VVOL Management.
On the Category pane, click VVOL Access Path.
The VVOL access path list is displayed on the Main pane.
On the Action pane, click Set under VVOL Access Path.
The Welcome page is displayed. Click Next.
The Specify Disk Array and Server page is displayed.
Select the ETERNUS Disk storage system and server for setting the VVOL access path, and then click Next.
The Specify HBA and Port HBA page is displayed.
When performing an FC switch zoning setting, select "Yes", otherwise select "No".
Perform the following operations for each HBA.
Check the Set Access Path checkbox for the HBA where the access path setting is performed.
Click Connect for the HBA that was loaded in the VMware host.
In the displayed dialog box, check the checkbox for the port of the connection target ETERNUS Disk storage system and then click OK.
Refer to the ETERNUS Disk storage system manuals and specify the host response that corresponds to the server.
When the input is completed, click Next.
The information confirmation screen is displayed. Confirm the information, and then click Set.
Point
The FC switch between the VMware host and the ETERNUS Disk storage system is registered as a device and when selected to perform as a zoning settings in step 7, the zoning of this FC switch is automatically configured.
After replacing the HBA hardware for the same slot on the server, perform an access path inheritance. When performing an access path inheritance, an inheritance is also performed for the access path that is set for the same server HBA and disk storage system port. Refer to "11.4.7 Inherit Access Path" for information on the access path inheritance procedure.
When changing the connection to an FC HBA of a different slot on the server, delete the VVOL access path, and after changing the access path, perform a VVOL access path reconfiguration. Refer to "9.19.4.3 Delete VVOL Access Path", "11.4.5 Change Access Path", and "9.19.4.1 VVOL Access Path Setting" for information on the various operations.
For the replaced iSCSI HBA, set with the same iSCSI Name and IP address that was set before the replacement. An access path inheritance operation is not required.
After deleting the VVOL access path and the access path, set the access path and VVOL access path again. Refer to "9.19.4.3 Delete VVOL Access Path", "11.4.4 Delete Access Path", "11.4.2 Add Access Path to ETERNUS Disk Storage System" and "9.19.4.1 VVOL Access Path Setting" for information on the various operations.
The procedure to delete the VVOL access path is as follows:
On the global navigation tab, click Storage.
On the Category pane, click VVOL Management.
The items of the Category pane change into the items concerning the VVOL Management.
On the Category pane, click VVOL Access Path.
The VVOL access path list is displayed on the Main pane.
On the Main pane, check the target VVOL access path checkbox.
On the Action pane, click Delete under VVOL Access Path.
The Delete VVOL Access Path page is displayed.
Confirm that the target VVOL access path is displayed, and then click Delete.
Point
In environments in which multipath is not configured, the VVOL access path in use (path that the virtual machine is operating) cannot be deleted. In environments in which multipath is configured, VVOL access paths can be deleted until there is only one VVOL access path remaining.
In an environment in which both an access path and a VVOL access path are set, if only one of access paths is deleted, FC switch zoning is not deleted. In both the access path and the VVOL access path are deleted, zoning is deleted.
The VVOL access path status is updated only when reloading the configurations for both the related ETERNUS Disk storage system and the servers. However, by performing an operation for updating the VVOL access path status, the latest status of the VVOL access path can be checked.
Update the VVOL access path status for the following situations:
When setting/changing/deleting the VVOL access path
When notified of an event that is related to a device or part that is related to the VVOL access path
The procedure to update the VVOL access path status is as follows:
On the global navigation tab, click Storage.
On the Category pane, click VVOL Management.
The items of the Category pane change into the items concerning the VVOL Management.
On the Category pane, click VVOL Access Path.
The VVOL access path list is displayed on the Main pane.
On the Action pane, click Reload under VVOL Access Path.
Information
When performing this operation, the VVOL access path status and access path status are updated simultaneously.
