scsiquiesce - stop all SCSI bus activity for a specific amount of time
scsiquiesce -q bus_quiesce_time [-t quiesce_in_progress_timeout]
scsi_host_adapter_device device ...
scsiquiesce is used to stop all operations on a SCSI bus for a specific
amount of time. Ctrl-C kills the quiesce. You can extend the quiesce
time by pressing the Enter key and inputting additional quiesce time.
When the quiesce completes, the bus is rescanned for new devices.
The options are:
Quiesce time in seconds. This required option informs the low level
SCSI driver how many seconds to quiesce the bus for.
How long the low level driver should wait (in seconds) to finish all
currently outstanding commands. If this option is not specified,
the default is 10 seconds.
-v Verbose mode.
/dev/scsi/bus* the SCSI bus operation devices
This command is normally usable only by the superuser, because the
standard permissions of the devices in /dev/scsi restrict access to other
If drives are removed or drive IDs change during the quiesce, bad things
This function is only implemented on *some* controllers.
