problem mounting cdrom

[nandkumar4aix]

hi all

i am using aix 4.3.2 on model c20 .
i am unable to mount the cdrom . i hav tried almost everything .
manually it ejects properly .i hav tried running cfgmgr also .
while issuing comm.
mount /dev/cd0 /cdrom
it gives me error like
mount : 0506-322 Cannot determine log device to use for /dev/cd0 (/cdrom)

and if u know please tell me the way to interpreat these system error massages (like 0506-322).

thanks
nan

Yes, the problem is you need to specify the filesystem to use to mount against.

Try this:

mount -v cdrfs -o ro /dev/cdrom /cdrom

The cdrom needs to have a filesystem associated with it to use for logging purposes. By default it is cdrfs, although sometimes this needs to be manually setup through smit(ty) first.

Oooops.... should be like this instead:

mount -v cdrfs -o ro /dev/cd0 /cdrom

Sorry, I fat fingered that real bad!

Have Fun!

hey.. Chuck

i hav tried this
mount -v cdrfs -o ro /dev/cd0 /cdrom
it gives me error like
mount :0506-324 cannot mount /dev/cd0 on /cdrom: the device is not ready for operation.

Do you have the CD in the cdrom when you mount it?

 

[nandkumar4aix]

no i dont ...
i hav tried both ways.. with cd and without cd..

any how does it affect???

you need to have the cd in the cdrom when you issue:

mount -v cdrfs -o ro /dev/cd0 /cdrom

you ALSO need to verify that the mount point (directory) /cdrom exists.... if that is what you are going to use.

And to reiterate... you need to make sure that you have the filesystem 'cdrfs' configured. To install the cdrfs filesystem if it does NOT exist, type:

smitty cdrfs

Try creating a mount point called temp in / (root).

Then try mounting cdrom.

mount /cdrom /temp

 

[cspilman]

The error:

'mount: 0506-324 Cannot mount /dev/cd0 on /cdrom: The device is not ready for operation.'

IS from the cdrom not seeing a cd.

Possible causes:

- cd need's to be reinserted
- cd is non-readable (no data or damaged maybe???)
- cdrom is bad

to check the latter, try inserting any of the original install media cd's and type:

smitty install_all

but don't install the software, just see if you can list the filesets off of the cd. If you can than the first two causes are probably why you can't mount other cd's in the cdrom.

Have Fun!

hey chuck
i hav tried that
it gives me same "device not ready error"

can u tell me how to interpreate from the code given with the error massage.

thanks

Have you read your errlog lately?

Try [tt]errpt -a| more[/tt] to search for hardware errors in your CD-ROM drive unit or SCSI bus...

I hope it works...

 

[cspilman]

I agree, the next step is to look at the hardware. If you don't see error's in the error report log, try using the diag util to see if there are any errors reported with the cdrom device.

hello,
I have the same exact problem with my cdrom on my AIX
workstation. I have a 7043-140 running AIX 4.3.3.
I didn't have the problem until after I upgraded
to 4.3.3. I have even tried running the diagnostics
thru smit. It didn't give me any info at all.
any help would be appreciated.

thanks,
james

Have you tried several different CDs? Is it possible that you have a bad CD or a CD not supported by cdrfs? Says the Manager to the person that invented the modem: "Tell me again why you need two prototypes?!?"

 

[ElgisRamon]

I have a standard install of 4.3.3 without patches with a 43P/140 and my CD functions properly... them must be a specific problem in your machine/software combination... Can you boot up from the CD (using SMS)?

I hope it works...

Hi Guys,

Try with this

mount /cdfs
