file copy from DVD fails - hangs system

[Dave Chamberlin]

Hello,
I am working on a new (refurb) RP8400 with a VA7410 disk array, running hpux 11.11. I am loading Oracle app software and doing cp -r of files from the DVD to the VA. Have copied several disks do far without problem. I was using pfs_mount. Yesterday, when copying the Disk3 dir, the copy hung and no copy activity was occurring. The copy command was giving nfs server mars not responding. A subsequent bdf also hung. I tried rebooting the system, which hung on stopping veritas Enterprise Adminstrator Service (vxsvc) - it stayed on that line all night. I had to reset power to interupt and reboot. Now I decided that pfs_mount may have been related to the problem and noted that my system has the rockridge extension patches, so I didn't need to use pfs_mount and used mount instead. Started copying the Disk3 directory and it is hung again. No errors or nfs messages. Cannot kill the cp command. Is there a way to regain control here? Any idea on what may be happening? Thanks

Dave,

It appears that it is waiting for I/O completion, and that means it is un-interruptable. I suspect you have bad media and would suggest you get it replaced before you try this again.

Dave,

Or - perhaps it's the VA/veritas that's at fault - that would account for the hang on shutdown. Try running a dd against the raw logical volume you're copying to and see if that hangs.

Thanks for the replies. The media is new DVD from Oracle and I have used it once on another machine without problems. The dd command ran happily against the disk devices used. Just to be on the safe side I killed the vxsvc process prior to rebooting and the reboot went normally. I am trying a different DVD this time. Could there be an issue with the DVD drive?

[Pete Randall]

It certainly could be the DVD drive, but the fact that your shutdown hung on stopping vxsvc, would incline me to be more suspicious of the VA.
