Shutting off a storage controller
This procedure describes how to shut off a storage controller.
Procedure performed by
: Solution administrator, or ThinkAgile Advantage Support (optional, via Chapter 4
“Support Mode” on page 23).
Execution
: On hardware
Storage controllers must be shut off in the storage controller itself, not in the Cloud Controller. To connect to
the OS running on the storage controller, connect your laptop to the storage controller and use the Hardware
Console available on the storage controller action menu in the Cloud Controller.
While connecting to the storage controller, enter the username
manager
and the password set during
installation. If you have forgotten the password, reset it in the Cloud Controller.
Notes:
Shutting off a passive storage controller is non-disruptive, but shutting down the active storage
controller disconnects all exported drives for the VMs. If you are shutting down the active storage controller,
either:
• fail over to the passive storage controller, or
• move the VMs to another storage node
After a successful sign-in, execute the following commands to shut down the storage controller at the node-
level OS:
> > ssu ud do o //u ussrr//b biin n//ttaaccp p--sstto orraag gee--cco on nttrro olllleerr--ssaaffee--sstto op p
> > ssu ud do o ssh hu uttd do ow wn n --h h n no ow w
When you initiate shutoff of the entire storage block, the Cloud Controller lists the VMs that have disks
exported to the storage block.
At this point, the shut-down storage controller can be pulled and serviced.
Trigger manual storage HA
This procedure describes how to trigger a storage HA, moving disk export control from the active storage
controller to the passive storage controller.
Procedure performed by
: Solution administrator, or ThinkAgile Advantage Support (optional, via Chapter 4
“Support Mode” on page 23 to ThinkAgile Advantage).
Execution
: On hardware only
To transfer disk export control from the active storage controller to the passive storage controller, you must
simulate an active storage controller failure, so the system safely generates a storage HA event. To do this,
you must simulate storage HA heartbeats between the Storage Controller service running on the active
storage controller.
