BIOCTL(8)               NetBSD System Manager's Manual               BIOCTL(8)


NAME

     bioctl -- RAID management interface


SYNOPSIS

     bioctl [-Dhiv] [-a alarm-function] [-b channel:target[.lun]]
            [-c raidlevel] [-H channel:target[.lun]]
            [-l special[,special[,...]]] [-u channel:target[.lun]] device


DESCRIPTION

     RAID device drivers which support management functionality can register
     their services with the bio(4) driver.  bioctl then can be used to main-
     tain RAID volumes.

     The options are as follows:

     -a alarm-function
             Control the RAID card's alarm functionality, if supported.
             alarm-function may be one of:

             disable  Disable the alarm on the RAID controller.
             enable   Enable the alarm on the RAID controller.
             get      Retrieve the current alarm state (enabled or disabled).
             silence | quiet
                      Silence the alarm if it is currently beeping.

             The alarm-function may be specified as given above, or by the
             first letter only (e.g. -a e).

     -b channel:target[.lun]
             Instruct the device at channel:target[.lun] to start blinking, if
             there is ses(4) or safte(4) support in the enclosure.

     -c raidlevel
             Create a softraid(4) device of level raidlevel.  The device must
             begin with ``softraid'' followed by a number.

     -D      Enable debug output.

     -H channel:target[.lun]
             If the device at channel:target[.lun] is currently marked
             ``Unused'', promote it to being a ``Hot Spare''.

     -h      Where necessary, produce "human-readable" output.  Use unit suf-
             fixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte,
             Exabyte in order to reduce the number of digits to four or less.

     -i      Enumerate the selected RAID devices.

     -l special[,special[,...]]
             Use special device list to create within the softraid(4) frame-
             work.  Requires -c.

     -u channel:target[.lun]
             Instruct the device at channel:target[.lun] to cease blinking, if
             there is ses(4) or safte(4) support in the enclosure.

     -v      Be more verbose in output.

     device  Select a drive by name (e.g. sd0) or a RAID controller by name
             (e.g. ami0).  For operations which will be performed against
             ses(4) or safte(4) enclosures, it is also possible to directly
             specify the enclosure name (e.g. safte0).


EXAMPLES

     The following command, executed from the command line, shows the status
     of the logical drives on the RAID controller:

     # bioctl -h mfi0
     Volume  Status           Size Device
      mfi0 0 Online            74G mfi0    RAID1
           0 Online            75G 1:0.0   noencl <ATA     WDC WD800JD-75MS1E04>
           1 Online            75G 1:1.0   noencl <ATA     WDC WD800JD-75MS1E04>
      mfi0 1 Online           697G mfi0    RAID5
           0 Online           233G 1:3.0   noencl <ATA     WDC WD2500JS-75N2E04>
           1 Online           233G 1:2.0   noencl <ATA     WDC WD2500JS-75N2E04>
           2 Online           233G 1:4.0   noencl <ATA     WDC WD2500JS-75N2E04>
           3 Online           233G 1:5.0   noencl <ATA     WDC WD2500JS-75N2E04>
