- Short: Parks devices and loads and ejects media
- Author: thor@math.tu-berlin.de (Thomas Richter)
- Uploader: thor@math.tu-berlin.de (Thomas Richter)
- Version: 1.10.1
- Type: disk/misc
- Requires: Os 2.04
-
- This tool ejects, parks or restarts a HD unit, either given by its DOS
- device name or the name and unit of the exec device driver. All partitions
- on the parked unit will be unaccessible to the dos afterwards. To be able to
- restart the HD, "Park" can be made resident.

-
- Version 1.10.1:
-
- Ooops. Forgot to include the 1.10 correctly. The 1.10 contained actually the
- 1.09 release of Park. Thanks to Nils Goers for detecting this fault.
- _____________________________________________________________________________
-
- Version 1.10:
-
- Major cleanup release. Added checks for some AFAIK undocumented SCSI ASC/ASCQ
- values I receive from my CD/RW which broke some commands. Added the "LOAD"
- argument to load a device (mainly CD-ROMs and related). Changed the ejection/
- loading/parking sequence a bit to keep care of some strange Iomega mechanisms.
- _____________________________________________________________________________
-
- Version 1.09:
-
- Added more sanity checks to avoid Enforcer hits.
- _____________________________________________________________________________
-
- Version 1.08:
-
- If the NOCHECK option is present, Park no longer rejects to "eject"
- empty drives, i.e. to open an empty CD drive or similar.
- Thanks to Nils Goers for testing.
-
- _____________________________________________________________________________
-
- Version 1.07:
-
- Fixed a bug that caused an unnecessary "out of memory" failure in case no
- disk to be ejected is present.
-
- Park uses now a smarter algorithm to decide whether the given argument is
- a dos device or an exec device name.
-
- Better check for the SCSI result codes, the error code returned is now
- more "AmigaDos like".
- _____________________________________________________________________________
-
- Version 1.06:
-
- Added a workaround for a feature of the gvpscsi.device and the FFS.
- _____________________________________________________________________________
-
- Version 1.05:
-
- Added a workaround for a bug in the AmiCFDS, added the NOCHECK option.
- _____________________________________________________________________________
-
- Version 1.04:
-
- Internal release, unpublished.
- _____________________________________________________________________________
-
- Version 1.03:
-
- Added the EJECT argument - *should* be used with the SCSI argument, too.
- Added the EJECTDELAY, STARTDELAY and FLUSHDELAY arguments that define
- command specific delays.
- _____________________________________________________________________________
-
- Version 1.02:
-
- Park checks now if a device is already parked (or, to be precise, if the
- filing system is shut down) and fails if the user tries to park it again.
- _____________________________________________________________________________
-
- Version 1.01:
-
- Added an explicit check whether the handler name supplied does really contain
- a colon.
- _____________________________________________________________________________
-
- Synopsis:
-
- Park HANDLER=DEVICE/A,UNIT/N,FLAGS/N,SCSI/S,
- ON=START/S,EJECT/S,LOAD/S,EJECTDELAY/K/N,STARTDELAY/K/N,
- FLUSHDELAY/K/N,INHIBITDELAY/K/N,NOCHECK/S
-
- HANDLER: DOS Device name to be parked, or name of the volume. To
- restart a unit, this must be the device name.
- This *must* be the name of the dos device driver, i.e.
- a string like "DH0:" or "SYS:".
- Alternatively, this may be the name of the exec.device, i.e.
- "oktagon.device" or "gvpscsi.device".
-
- UNIT: The unit number of the exec device. Makes only sense if
- HANDLER is an exec style device name.
-
- FLAGS: The flags for opening the device. Defaults to zero and is
- usually not required.
-
- SCSI: If given, try to park the unit with direct SCSI commands.
- This should work with all scsi.device compatible device
- drivers.
- If not given, try to use the TD_EJECT, CMD_START
- and CMD_STOP.
-
- Unfortunately, most device drivers do not support
- TD_EJECT, CMD_START/STOP. The "SCSI" keyword is
- therefore almost always required.
-
- ON=START: Restart the device and the partitions in question.
-
- EJECT: Eject the given device, if possible. In almost all
- cases the SCSI keyword IS required since there is almost
- no device which implements the - documented though -
- command TD_EJECT
-
- LOAD: Loads the given device, e.g. CD-ROMs. Since there is no
- exec command that is supposed to support this, the SCSI
- keyword is mandatory here.
-
- EJECTDELAY: The delay in 50th of seconds Park should wait after
- ejecting and before re-running the filing system. Defaults
- to 50, i.e. one second.
-
- STARTDELAY: The delay in 50th of seconds Park has to wait after
- having started a device until the filing system is allowed
- to touch the disk again. Thus, this should be the spin-up
- delay of the device. Defaults to 50, i.e. one second.
-
- FLUSHDELAY: The delay in 50th of seconds Park waits for the filing
- system to execute ACTION_FLUSH, i.e. to flush its buffers
- to the disk. Unfortunately, this packet is broken - which
- requires this ugly, and unsafe(!) workaround.
-
- INHIBITDELAY: The delay in 50th of a second park waits after stopping
- the filing system and before parking the device. This is
- required by the gvpscsi.device since this device fiddles
- on its own in the device list of the DOS (Bah!) and may
- lead to enforcer hits of the FFS. Defaults to one second.
-
- NOCHECK: Bypasses the test if the filing system of the drive(s) to
- be parked is up and working. If you see a message like
- "Drive xyz is already stopped", but the handler is just
- disabled for whatever reason, insert this argument.
-
- _____________________________________________________________________________
-
- Examples:
-
- Park all partitions on the oktagon.device, unit 2:
- (The oktagon knowns CMD_STOP, SCSI is not required)
-
- Park oktagon.device unit 2
-
-
- Park all partitions on the gvpscsi.device, unit 6:
- (The gvpscsi.device does NOT know the CMD_STOP, SCSI is required)
-
- Park gvpscsi.device unit 6 scsi
-
- The "device" keyword is very important in both cases.
-
-
- Park the partition DH0: and all other partitions on the same device:
-
- Park DH0: scsi
-
-
- Restart DH0: and all other partitions on that device:
-
- Park DH0: on scsi
-
-
- Eject a ZIP drive, named ZIP:
-
- Park ZIP: scsi eject
-
-
- Eject a SCSI CD, named CD0:
-
- Park CD0: scsi eject nocheck flushdelay=0 ejectdelay=0
-
- A flush delay isn't needed here because a CD filing system can't write
- anything to a CD.
