# spmgr display -a HBA
Use this feature to move I/O to another adapter as the first step to replacing an HBA.
Example:
# spmgr quiesce -a td0
# spmgr quiesce -c controller_serial_number
When this command is invoked, spmgr moves all active I/O using this controller to paths on the
other controller of the storage system. The paths of the specified controller are marked as quiesced
and no further I/O is sent along that path until the controller returns to service with the restart
command.
You can verify these actions by entering the following command to view the current path state.
# spmgr display -c controller_serial_number
Use this feature to move I/O to another controller as the first step to upgrade or replace a controller.
Example:
# spmgr quiesce -c ZG11233409
# spmgr quiesce -p path_instance
When this command is invoked, spmgr moves all active I/O using this path to another path on the
same controller, if possible, or to a path on the other controller. The specified path is marked as
quiesced and no further I/O is sent along that path until the restart command returns the path to
service.
You can verify these actions by entering the spmgr display command to view the current path
state.
Example:
# spmgr quiesce –p c12t0d5
restart command
Object restarting changes a quiesced adapter or controller to an available or standby state. When
restarted, the HBA or controller is available as an I/O entity for a path.
Syntax:
# spmgr restart [option]
Options:
-a <adapter>
-c <controller_ser_num>
-p <path instance>
all — Full system-wide restart
NOTE:
The restart command returns successfully if no restart action is taken by the driver. For example,
if a restart is issued to a path that is not quiesced, the command returns successfully.
The restart command provides the following options:
