I am having problems sending the fixate command to a HP6020i CDR.
The worm.c code burns the file system but dies when the final
fixate command is given. Resulting in a useless CD. Doing a dry run
with the dummy option is fine. The only changes I have made was;
1) add the following to the scsiconf.c code to identify the device at
boot time.
{
T_READONLY, T_WORM, T_REMOV, "HP", "CD-Writer 6020", "*",
"worm", SC_ONE_LU
},
2) commented out the two calls "scsi_stop_unit" and "scsi_prevent"
in the worm_close function in worm.c.
These lines seemed to casued the drive to report "Not Ready" for
any command after the "wormcontrol select HP 4020i" was run.
Opening and closing the CDR clears the message.
Here is the run that failed
# wormcontrol select HP 4020i
# wormcontrol prepdisk double
# wormcontrol track data
# rtprio 5 team -v 1m 5 < cnsn8.cd | rtprio 5 dd of=/dev/rworm0 obs=20k
631938 kilobytes, 2099 seconds
1263876+0 records in
31596+1 records out
647104512 bytes transferred in 2109.314342 secs (306784 bytes/sec)
# wormcontrol fixate 1
wormcontrol: ioctl(WORMIOFIXATION): Input/output error
#
Note: 3-5 second delay from fixate command and error message (as I recall).
>From the worm.c code
hp4020i_finalize_disk(struct scsi_link *sc_link, int toc_type, int onp)
{
struct scsi_fixation cmd;
SC_DEBUG(sc_link, SDEV_DB2, ("hp4020i_finalize_disk"));
if (toc_type < 0 || toc_type > WORM_TOC_TYPE_CDI)
return EINVAL;
/*
* Fixate this session. Mark the next one as opened if onp
* is true. Otherwise, the disk will be finalized once and
* for all. ONP stands for "open next program area".
*/
bzero(&cmd, sizeof(cmd));
cmd.op_code = FIXATION;
cmd.action = (onp? WORM_FIXATION_ONP: 0) + toc_type;
return scsi_scsi_cmd(sc_link,
(struct scsi_generic *) &cmd,
sizeof(cmd),
0, /* no data transfer */
0,
1,
20*60*1000, /* takes a huge amount of time */
NULL,
0);
}
It would appear that scsi_scsi_cmd is returning EIO ???
If I am way off base perhaps someone could suggest a more likely
location for the problem.
I hate to create more coasters for my coffee cup.
Thanks,
John

F.Y.I. More background...
The HP-4020i scsi command info is in the http://www.hp.com/isgsupport/cdr
under product info.

According to various people, the philips cdd2600 is the same unit as the
HP6020. From the philips site they have a manual for the 2600 which gives
the scsi command set used.
