Use this feature to move I/O to another adapter as the first step to replacing an
HBA.
Example:
# spmgr quiesce -a 2300-1
# 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 will then be marked as quiesced, and no further I/O will be sent along
that path until the controller is returned to service with the restart command.
These actions may be verified by issuing the
# spmgr display –c controller
command to view the current path states.
Use this feature to move I/O to the other controller as the first step to upgrading or
replacing a controller.
Example:
# spmgr quiesce -c P56350A91MN19M
# 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 will then be marked as quiesced, and no further I/O
will be sent along that path until the path is returned to service with the restart
command.
These actions may be verified by issuing the spmgr display
command to
view the current path states.
Example:
# spmgr quiesce –p hsx_mod-1-0-0-2
The restart command
Object restarting changes a quiesced adapter, controller, or path to an Available or
Standby state. When restarted, the HBA or controller is available as an I/O entity
for a path.
