Hi,
I have mounted one cd (approx. 200mb) to install some softwares.
/dev/dsk/c1t0d0 7846572 7846572 0 100% /cdrom
# cd /cdrom
# ls -l |wc -l
1207
#
# fstyp /dev/dsk/c1t0d0
cdfs
#
But when i am trying to install packages from that mounted /directory (/cdrom), getting below error.
#swinstall -s /cdrom
"mymachine:/cdrom": An I/O error occurred while performing this task.
Any idea, why it is giving me I/O error ?
Am i doing something wrong ?
Thanks in advance.

Solution
Run the below command to check the software available on the CD.
# swlist -l product -s /cdrom
If the above command fails, then there might be issue in reading the software installation files and you would need to try a different software media.

Re: ":/cdrom": An I/O error occurred while performing this task.
Hi Pradeep,
thanks for quick reply.
As per you have mentioned above, I have executed the command.
/dev/dsk/c1t0d0 7846572 7846572 0 100% /cdrom
# swlist -l product -s /cdrom
# Initializing...
# Contacting target "mymachine"...
ERROR: The depot "mymachine:/cdrom" exists but is currently empty.
#
I also have iso of these softwares. After mounting the iso, still facing the issue.
# lvcreate -L 1024 -n iso /dev/vg00
Logical volume "/dev/vg00/iso" has been successfully created with
character device "/dev/vg00/riso".
Logical volume "/dev/vg00/iso" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
#
# dd if=/opt/hp-ivm/image.iso of=/dev/vg00/riso bs=1024k
I/O error
167+1 records in
167+1 records out
#
# mount /dev/vg00/iso /mnt
# swlist -l product -s /mnt
# Initializing...
# Contacting target "mymachine"...
ERROR: The depot "mymachine:/mnt" exists but is currently empty.
#
Could you please help me.
Regards,
tushar

Above dd command failed with io error. I think the iso image file might be corrupted too.. so I would recommend to check with different software media..
Once you have the replaced media, run the "swlist -l product -s /cdrom" if this command succeed then swinstall would work..

What does "ll /cdrom" show? (don't list all 1,200 files)
>After mounting the iso, still facing the issue.
If you are on 11.31, there are easier ways to mount ISO images.
>I/O error
Hmm, was the error on the input or output file?
dd if=/opt/hp-ivm/image.iso of=/dev/null bs=1024k
>ERROR: The depot "mymachine:/mnt" exists but is currently empty.
What does "ll /mnt" show? (The same 1,200 files?) You may have to go deeper.

Re: ":/cdrom": An I/O error occurred while performing this task.
I/O error means media error. You have a smudged CD or your CDROM drive is dusty or simply defective. For a 'normal' CD, there is no software error that will create an I/O error. HOWEVER, if you created the CD on a PC, be very aware that a lot of PC-based software tries to make a CD into floppy that you can append (write) more records at a later time. This packet writing technique is completely incompatible with HP-UX (and even other PCs if you don't properly close the open CD).
So start by putting a standard HP-UX CD in your drive and see if you can mount it. If it also gets an I/O error, replace the CDROM drive. (you could try using a 'cleaner-CD' with little brushes). If it does work, then the recoding software used to burn the CD is incompatible. Get a copy of ImgBurn. Roxio, Nero, even Windows is too far removed from reality to be useful except to save some photos and movies for other PCs.
