newfs I/O error.
sammysammy
Hi,
I want to crecate a new fs for a hard disk, but it generated the
following err msg:
root@unixser2 ~ # newfs /dev/rdsk/c0t2d0s0
/dev/rdsk/c0t2d0s0: I/O error
root@unixser2 ~ #
The following is the prtvtoc output:

Where is partition 0?
You have not formatted that disk yet.
sammysammy
Is the option Format in the command format will do the formating for me?
It is still doing the formating now after 2 hours. Is it normal to take
so long on a 36G hard disk?
What should I do after the format operation finish?

Format is done almost instantly. Your output from prtvtoc must show
that you have created the partition which you are trying to build a new
filesytem on:

mkfs(1M) or newfs(1M)
But that took only a few minutes on a 60GB drive.

You shouldn't run format.format, it's not going to do anything
useful and on many disks it takes a long time to finish. Nowadays,
there's no such thing as an unformatted disk that requires low-level
formatting. If your disk is less than ~8 years old, then the chances
are 99.9% that it's already formatted and physically reformatting
it isn't possible, and logically reformatting it does nothing but waste
time (unless the drive is smart and simply ignores the format command
and claims the format operation completed immediately).
Rather than randomly trying things you should go read the Sys Admin Guide
and learn the right way to set up a new disk:
http://docs.sun.com/?p=/doc/805-7228/6j6q7uetq&a=view
Or search through the google archives for any of the hundreds of
times that the question, "how do I init a new disk on Sx86?" has been
asked and answered.

I finished newfs with the following command:
root@unixser2 ~ # newfs /dev/rdsk/c0t2d0s2
root@unixser2 ~ # mount /dev/rdsk/c0t2d0s2 /Projects
mount: /dev/rdsk/c0t2d0s2 not a block device
root@unixser2 ~ #
I also don't know why c0t2d0s0 failed with newfs.
SW
a sub-format command. I use fdisk created an entire partion for the Solaris
type filesystem, and label it. Then newfs /dev/rdsk/c0t2d0p0 failed with I/O
error. Here is what I stuck with. I don't know why I/O has error with newfs.
Thanks

I think you really don't have a good understanding of what a Solaris slice
is. I suggest you backup to at least Chapter 25 in Vol 1 of the Sys Admin
Guide and get a little background under your belt rather than jumping
right in to the middle of Chapter 31. You also need to learn to stop and
do some research when you encounter a technical term you don't fully
understand (rather than assuming you can guess at its meaning from the
context).
In fact you probably should start at Chapter 1 because your next set of
questions is probably going to be "how do I add a user?", or "how do I
install the latest Kernel Jumbo Patch?", or something else that's already
fully explained in the documentation.
If the Sys Admin Guide is too dry for you and/or if you prefer something
more chatty then maybe your local bookstore might have a Solaris 8 or 9
book that might be more helpful.

The format utility will not create such a partition.

Of course I know groudadd xxx; adduser -u 512 -g xxx -m -d /export/home/xxx

Do you know what those final digits mean?
Well, that should tell you a lot.

directory. Thanks for everyone's comment. Now I remember I did created an
incorrect partition in the first disk c0t0d0p0. I want to increate the p0
disk to full size of the hard disk. I have removed the second partition
(c0t0d0) in the first hard disk, how can I in create the first partition so
that it utilise 100% of the first hard disk?
Thanks

you are still unclear on the concept.
c0t0d0p0 means "Access the raw disk in its entirety",
ignoring fdisk type partitions.
However, without fdisk partitions, it is rather difficult to BOOT.
Sounds like the simplest explaination for you, is:
reinstall solaris, but this time,choose "customise disk", and when the
fdisk partition tool comes up, choose "use entire disk for solaris"

any procedure I can follow to reszie the partition? Sorry I am not too
familiar with Solaris's disk configuration.

in the reinstall, you should have deleted the old fdisk partition, and then
it would have removed the old info, and made a new one for you.
Then you recreate the slices however you want, when it asks you about
filesystems. Again, choose the "customize" option, when it starts asking
about filesystem layout.
its a two-step process. You first set the "fdisk partition" up.
Once that is done, you lay out the solaris "slices" in that partition.
