[ANNOUNCE] sdparm 0.92

[ANNOUNCE] sdparm 0.92

[Douglas Gilbert]

sdparm is a command line utility designed to get and set
SCSI disk parameters (cf hdparm for ATA disks). More generally
it gets and sets mode page information on SCSI devices or devices
that use a SCSI command set (e.g. CD/DVD drives (any transport)
and SCSI tape drives). It also can list VPD pages including
the device identification page.

For more information and downloads (tarball, rpm and deb
packages) see:
http://www.torque.net/sg/sdparm.html

There are now more than 150 parameters accessed by sdparm.
Thanks to Kai Makisara for interface and sanity checking
suggestions.

ChangeLog for sdparm-0.92 [20050520]
   - add data compression and device configuration mode
     pages (ssc3)
   - add timeout + protect plus write parameters mode
     pages (mmc5)
   - add XOR control mode page (sbc2)
   - add SES management mode page (ses2)
   - discriminate mode pages based on device's peripheral
     device type
   - disallow set/clear acronyms whose pdt doesn't match
     current device
   - with option "-ll" decode more of INQUIRY standard
     response
   - improve error checking when getting non-existent
     fields
   - use double fetch technique when fetching mode pages
   - add RBC device parameters mode page (rbc)
   - add '--flexible' option for mode sense 6/10 response
     mixup
   - '--inquiry -all' now outputs supported VPD pages page

This has gone beyond "creeping featurism" to cavorting and gamboling 
featurism! ;-)

I pulled a copy to try over the long weekend if not before, this looks 
as if it will be a valuable documentation tool, which is useful to CYA 
even if never used otherwise.

Nice! Just got it and tried on an external usb disk.
One feature I could use, probably others as well:
Could you add the ability to spin down/up a scsi disk?
I'd really like this for exteral (usb) disks.

Doesn't seem it can; if I missed it, I'm sorry..

Mogens,
With sg_start (in the sg3_utils package) I have tried
to spin up and down an ATA disk inside a USB enclosure
without success. The same command on a USB connected
CD/DVD combo drive did work.

Could you try sg_start on your USB external enclosure
which I assume contains an ATA disk rather than a
SCSI (SPI) disk and report if it works?

BTW I just checked libata (for SATA disks) and it does
not seem to support the START STOP UNIT command.
Jeff, could that one be added?

> Doesn't seem it can; if I missed it, I'm sorry..

It is hard to know where to stop with sdparm ;-)
At the moment I am adding transport (protocol) specific
mode page support. So currently sdparm specializes
in mode pages (for all SCSI command sets) and INQUIRY
information (including the device identification VPD
page).

Sure. Got it, compiled, but got the error:
   .../usr/include/scsi/sg.h /usr/include/scsi/scsi.h
   /usr/include/stdint.h   sg_lib.h sg_cmds.h llseek.h
   gcc: cannot specify -o with -c or -S and multiple compilations
   make: *** [sgp_dd.o] Error 1

I could only find  -o  and  -c  in the makefiles around line 95.

Slack 9.1 / 2.6.10 from sources.

It's 4am, I'm off to bed, sorry :p

Ehh.. I don't follow you here..
INCLUDES seems left undefined and hence evaluates empty, so yes, you can 
provoke an error by defining some nonsense, but since I cannnot compile, 
something's wrong: my gcc version, your makefile, or my (½empty) mind.

My mistake..

Guess not, but that's what they call it. Marketing.. :p
How doy you tell that it's the the interface, not the disk, that has 
those limitations? For sure, it's a Seagate 7200.7 ATA, so I guess it 
should have the same features as the other interface-types of the same..
Anyways, damn!

Yeah, I just don't need to spin 'em up/down ;)

As I said ealier, I'll keep looking; just got back in the saddle.
I cc'd to linux-scsi, in case someone has interesting input.

Dear oh dear!  Forgot to tell you I did:
   make clean; make dep; make

Doing just  make clean; make  did the job. Sorry about the problems.
Still,  make dep  ought to work :p

Doesn't change the fact that either my Prolific interface or the disk 
doesn't support the needed scsi modes..
