sd6 Cdrom device help needed 3

[gallows]

Below is the output of iostat on a Solaris 9 system. I need to mount a cdrom and cannot use vold, autofs etc. I have to mount it manually. Normally, the cdrom on our systems are on c6t0d0s0. What is this sd6 and what command would I use to mount a cdrom?

# iostat -En
sd6 Soft Errors: 1 Hard Errors: 0 Transport Errors: 0
Vendor: TOSHIBA Product: DVD-ROM SD-M1711 Revision: 1005 Serial No:
Size: 0.00GB <0 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 1 Predictive Failure Analysis: 0

Thanks,
Fred

mount -F hsfs /dev/dsk/c6t0d0s0 /mnt should do the trick. "hsfs" stands for High Sierra File System.

just to double check this. If your cdrom is c6t0d0s0 than it is externally attached to the system through a scsi controller correct.

If it is internal than it is targeted as c0t6d0s0 most likely since this is Suns default for cdroms.

Thanks

sure? usually they are c0t6d0s0

>> mount -F hsfs
I would add a "-o ro" after that; check "man mount_hsfs" for more info

Thank you all for the great responses.
This is for an internal cd/dvd drive on a sun 280R.

If the device address is c0t6d0s0, why doesn't that show up in the iostat -En and sd6 does? Is there a way I can verify the correct address? This is a production server and I don't want to hose anything up.

iostat -En normally displays the names in c0xxx format
iostat -E doesn't and displays sdxx. Are you sure you're using the n option. If not try it without

 

[gallows]

Thanks marrow. Yes I am sure I used the -En. My original post is copied/pasted. I tried the other options as well along with the -i.

hmm, not sure why it shows sd6

to get realy "good answers" which device is what you better use a scsi inquire program. I usually used the inquire from Legato Networker/Solstice Backup (install at least SUNWsbus2 - you will not need a license to do so)
# grep inquire /var/sadm/install/contents
/etc/LGTOuscsi/inquire f none 0555 root bin 680640 20066 1069888559 SUNWsbus2

you will get things like that:
# /etc/LGTOuscsi/inquire
scsidev@0.6.0:TOSHIBA DVD-ROM SD-M14011009|CD-ROM, /dev/rdsk/c0t6d0s2
scsidev@2.0.0:ATL P1000 62200701. |Autochanger (Jukebox)
.....

I have installed Version 6.1, which is pretty old...

Thanks Franz. Unfortunately I am at a gov site and cannot install anything without an Act from Congress)
I will get it and see if I can put it in out lab.

If you have Veritas Volume Manager installed /usr/lib/vxvm/diag.d/vxdmpinq is similar to the Legato utility.

attached is the scsi bus paths for the 280R.

run ls -al /dev/dsk/c0t6d0s0 and you will see the path for the cdrom. Check this against the path list I attached and you can be sure of what you are looking at.

Sun Blade[TM] 1000/2000, Sun Fire[TM] 280R, Netra[TM] 20
PCI Slot 1 /pci@8,600000/pci@1,* 33/66mhz-32/64bit-3.3V
PCI Slot 2 /pci@8,700000/pci@3,* 33mhz-32/64bit-5V
PCI Slot 3 /pci@8,700000/pci@2,* 33mhz-32/64bit-5V
PCI Slot 4 /pci@8,700000/pci@1,* 33mhz-32/64bit-5V
Internal Drives /pci@8,600000/SUNW,glc@4/fp@0,0/ssd@<WWN>
Internal SCSI bus /pci@8,700000/scsi@6/<device>

Tape Drive /pci@8,700000/scsi@6/st@4,0

External SCSI Port /pci@8,700000/scsi@6,1/<device>
External USB /pci@8,700000/usb@5,3/<device>

I also ran this command that seems to give you what you are looking for.

ls -al /dev/sd6*

Thanks

CA

 

[gallows]

Thanks CA. Here is what I got.

# ls -al /dev/dsk/c0t6d0s0
lrwxrwxrwx 1 root root 42 Jan 24 20:53 /dev/dsk/c0t6d0s0 -> ../../devices/pci@8,700000/scsi@6/sd@6,0:a

So that confirms sd6 is the cdrom. I also checked /dev/dsk
and it contains my 2 internal hard drives along with c0t6d0s0 so I feel better.)

Yes, it works. I can mount it.
Many thanks CA and Annihilannic, Franz, and Marrow.
I appreciate you alls help very much.

Regards,
Gallows

 

[gallows]

Uh oh. I do not have a /dev/sd6. In fact, I did a search on sd6* and can't find it anywhere.
That's ok though because I can now use the cd.

Thanks again CA for all your help.

 

[Annihilannic]

To find the device path for sd6 is not so straightforward, this is the command I use (I actually have a wrapper script to make ie easier to type!):

[tt]awk '$3 =="\"sd\"" && $2 == 6' /etc/path_to_inst[/tt]

Annihilannic.

 

[sunny1504]

Try 'cfgadm -al' thats the best ways to say where CDROM is connected.

ups, I see. Ok, you COULD run the inquire without installing the package on the host but burn the files on a CD and set LD_LIBRARY_PATH to this dir.
But just ask the guys in Langley if it is realy safe...

Thanks for the star!
