18GB drive in a A3311A attached to a D380. drive looks fine at first then when I do a newfs it says that it is not there. see attached. I tried moving to different slots and rebooting the system many times. Any help would be appreciated!!

Hi Daniel,

Plan a wake, cause it's a dead puppy.
Get it replaced.

Rgds,
Jeff

Hi,

It looks like you are doing your 'newfs' command on the raw disk device. Are you using LVM on this system? If so, you would want to do a 'pvcreate' on the raw disk, add it to a volume group, create a logical volume, and then do your 'newfs' on the logical volume.

Your disk doesn't seem to be too happy now that the 'newfs' tried to run on it. I'm not sure what you can do to make it good again.

Looks like you have a bad disk.

I would check by issuing

dd if/dev/dsk/c?t?d? of=/dev/null

If this completes disk is there, if it hangs/ aborts I would get HP to replace

If its a built in hot swap, it can be repalced while the system is running.

These disks don't fail often, but its quite dead.

Other possible causes: drive cage or cable failure. Since however the other drives are okay and this apparently has not happened recently, its probably just the one disk.

Hope you have a hardware contract, because those puppies are expensive.

Try with:

newfs -F hfs /dev/rdsk/cXtXdX

if you don' t specify the -F option the /etc/default/fs is used for determining the file system type.

From man newfs:

Execute the newfs command to create an HFS file system on /dev/rdsk/c1t0d2

newfs -F hfs /dev/rdsk/c1t0d2

I agree that this looks like a bad disk. Or does the NO_HW stay with the slot? If so, bad slot in the A3311A or cable/termination problem.

Ive concluded that the drive is bad. The problem moves to what ever slot I move the drive in question to. basically when the system is rebooted the drive comes up as claimed but as soon as I do a newfs, pvcreate, dd, or whatever to the drive the system says that it does not see it.
Thanks for all of your help!!!
