Mount CD ROM Error 1

[Tranbo]

Question for SCO-OSR6

what is the proper command to mount the CD-Rom? my CD-Rom is recognized by the system below:

Alias - Address - Inquiry String
-------- -------- --------------
hba3 - c1b0t2 - (ide,1) Generic IDE/ATAPI
cdrom1 - c1b0t0l0 - SONY DVD RW DW-Q120A PYS1

See sc01(7) for information about CD-ROM device nodes.
#

Here is the error

# mount /dev/rcd0 /cd-rom
UX:mount.svr5: ERROR: File system type cannot be determined
# mount -F iso9660 /dev/rcd0 /cd-rom
UX:cdfs mount.svr5: INFO: CDFS mount is read-only.
UX:cdfs mount.svr5: ERROR: Cannot mount: /dev/cd0
UX:cdfs mount.svr5: ERROR: I/O error
#

Try other tips from this forum still doesn't work

# mkdev cdrom
Mass storage devices are configured automatically
when the system is booted with a new device present.

Current CD-ROM configuration:

Alias - Address - Inquiry String
-------- -------- --------------
hba4 - c2b0t2 - (ide,1) Generic IDE/ATAPI
cdrom1 - c2b0t0l0 - SONY DVD RW DW-Q120A PYS1

Thanks advance for your help.

# dtype /dev/cd0
/dev/cd0 I/O error

when I put in the installation media the kernel will boot up and I was able to install from CD-Rom...but I can't install mp2 from CD-ROM because of CD is not available

 

[Tranbo]

Any one? I'm about to give it up on getting this CD-Rom mountable.

The mystery here is the CDROM drive only work when install new server and after that it no longer available for the new server install ?????

 

[edfair]

does 6 list devices during boot like earlier systems? that would give you the right device name to use. should be able to confirm that it exists in /dev.

My experience is all 5.0.5 or earlier so may not apply.

And is there a mountable CD in the drive?

Yes, there is a cd with MP2 on it, I can read and install mp2 on other server. I can also burn CD on this Server using command line below. but I can not mount the D_mn! CD Drive

mkisofs –f –R –r –l –J –V “DiskLabel” –o /u1/tmp/rwdisk.isa RWARC

cdrecord –v –pad –data –sao /u1/tmp/rwdisk.isa

 

[edfair]

And the crosscheck in 5.0.5 is in /etc/cdrecord for the hardware device IIRC. Should match with what you are attempting to mount.
This from memory, don't have a system up at present.

Understand the frustration. Went through it with SCSI devices until I built up stock so I could test by swapping.

Ed, we are on to something here...

content of CD Record

# The default device, if not specified elsewhere
#
CDR_DEVICE=ide

# drive name device speed fifosize driveropts
#
teac= 1,3,0 -1 -1 ""
panasonic= 1,4,0 -1 -1 ""
plextor= 1,4,0 -1 -1 ""
sanyo= 1,4,0 -1 -1 burnfree
yamaha= 1,5,0 -1 -1 ""
ide= 2,0,0 -1 -1 burnfree
cdrom= 0,6,0 2 1m ""


The mkdev hd shown ide is the correct parameter...I think

# mkdev cdrom

Got it!!!! to work by accident LOL

Using the media created with cdrecord using command line above on this server it work!!!!. In this case the media was a DVD-R format

# mount /dev/cdrom/cdrom1 /cd-rom
UX:cdfs mount.svr5: INFO: CDFS mount is read-only.
#

All other CD media will not work.

Thank-You all for helping.

 

[Tranbo]

Here is more info on this drive ...per PH advice

# dtype /dev/cd0
/dev/cd0 : RCKRDG filesystem

 

[Tranbo]

My conclusion at this point is: The Server can only read and mount what it created...kind like "don't eat what it didn't kill" LOL I believed it is can only read and create rockridge files format see the bottom of this post

Nothing on my 5.0.5 systems is DVD so my experience may have no relevance but I move(d) stuff built by cdrecord on CDs between machines without issues back when I was transferring data between 15 or 16 machines.

Because all the systems had SCSI tape before I shifted to CDR the units I used for burning were also SCSI to keep the I/O simple. Anything I built and burned on the drives would then go onto the system by "mount /dev/cd0 /cd0" with no switches. The data backup, the ISO build from the backup, the burning of the image, and a later move of the backup to the storage queue were CRONTAB driven. It also helped that the data and CDR were on different controllers and that any transfers, data to backup, backup to ISO, ISO to burner, and backup to backup queue never involved one controller or one drive for both duties.

You might want to try burning and reading with different switches to see what effects that might have.
