reset_bus This command causes the system to generate a SCSI bus reset
condition on the associated bus. A SCSI bus reset condition
causes all devices on the bus to be reset (including clearing all
active commands on all devices).
-k Continue processing arguments even after an error is detected. The default behavior is
to exit immediately when an error is detected.
Command line syntax is always verified for correctness, regardless of the
-k option.
Improper command line syntax causes
scsictl to exit without performing any opera-
tions on the device.
-m mode Display the status of the specified mode parameter. mode can be one of the following:
immediate_report
For devices that support immediate reporting, this mode con-
trols how the device responds to write requests. If immediate
report is enabled (
1), write requests can be acknowledged
before the data is physically transferred to the media. If
immediate report is disabled (0), the device is forced to await
the completion of any write request before reporting its status.
ir Equivalent to immediate_report
.
queue_depth For devices that support a queue depth greater than the system
default, this mode controls how many I/Os the driver will
attempt to queue to the device at any one time. Valid values
are (1−255). Some disk devices will not support the maximum
queue depth settable by this command. Setting the queue
depth in software to a value larger than the disk can handle
will result in I/Os being held off once a QUEUE FULL condi-
tion exists on the disk.
-m mode=value
Set the mode parameter mode to value . The available mode parameters and values are
listed above.
Mode parameters that take only a binary value (
1 or 0) can also be specified as either
on
or off, respectively.
-o command
Currently this option supports only the following command:
ola_params This command should be followed by five arguments namely,
hw_path , scsi_id , width , period , and offset. Actual values of
scsi_id , width, period and offset are decided by the hardware.
If the hardware is not capable of supporting the requested
values, they will be brought to the maximum capability of the
card. A value of -1 may be specified for scsi_id , width , period
and offset in order to use the hardware default values.
Note: This command does not validate any of the arguments
passed. Therefore, it does not show any output upon successful
completion.
-p pr_clear key device
Use the scsictl command with the -p pr_clear option to clear the persistent reser-
vation from a device. This command cannot be used with any other scsictl options or
commands.
This command should be followed by two arguments: key and device. key is a string of
characters which was used while setting persistent reservation. This key can be in any of
the following two formats:
(a) Text format: can contain any of alphanumeric characters. In this format length of
the key should not exceed 8 characters.
(b) Hex format: preceded by 0x or 0X, can contain any of hexadecimal digit. In this for-
mat length of the string should not exceed 18 characters in total (including 0x or 0X).
