Perform maintenance blocking for storage nodes as follows.
Before performing maintenance blocking by using the VSP One SDS Block Administrator, verify that maintenance blocking is possible according
to Verifying the conditions for performing storage node maintenance
blocking.
-
Blockade the storage node in the Storage Nodes list tab (in the Storage Nodes window) or
Storage Node detailed information window by either of the following means.
-
In the Storage Nodes list tab in the Storage Nodes window, select the storage
node (one node) to be blocked, click the preceding icon to the right
of the Monitor link icon, and then select Maintenance
Blockade.
-
In the Storage Nodes list tab in the Storage Nodes window (displayed as
inventory view), click the preceding icon displayed for the storage
node to be blocked, and then select Maintenance
Blockade.
-
Click the preceding icon in the Storage node detailed
information window for the storage node to be edited, and then
select Maintenance Blockade.
The storage node maintenance blocking dialog is displayed.
-
Verify the displayed information, and then click Submit.
The storage node maintenance blocking dialog is closed and
storage node maintenance blocking is performed.
-
When the following "Completed" message is displayed, processing is
completed.
-
If you are logged out during blockage processing, verify the Jobs window.
In some cases, storage node maintenance blocking takes a long time, which might
cause logout.
In the Jobs window, verify a job whose PATH is
“/v1/objects/storage-nodes/<id>/actions/block-for-maintenance/invoke”*.
If the STATUS is "Completed", storage node maintenance blocking is
successfully completed.
* <id> represents the ID of the target storage node.
CAUTION:
The Jobs window only shows jobs performed by the user. Therefore, once
you are logged out, log in as the same user as when performing storage
node maintenance blocking.
-
(Cloud for Microsoft Azure) In the Azure portal, verify that the status of the storage node
VM (Azure VM instance) blocked for maintenance has become "Stopped
(Deallocated)".
CAUTION:
In the Azure portal, verify that the status of the Azure VM instance blocked
for maintenance has become "Stopped (Deallocated)". If it is not
"Stopped (Unallocated)", stop the corresponding Azure VM instance from the Azure Portal and
make it "Stopped (Unallocated)". In Microsoft Azure, if the status of an
Azure VM instance is "Stopped", the billing status of the Azure VM
instance will continue. If it is "Stopped (deallocated)", the billing
status will not be continued (the disk billing status will be
continued). Check the Microsoft Azure
document for how to stop the system.
