Reply-to: erik@naggum.uio.no (Erik Naggum) Hello, fellow ultrix users! At the University of Oslo we have a uVax II which acts a gateway between DECnet and IP, and it's being used to spool print requests from a DECSYSTEM-2065 onto an Imagen 7320 printer. I wrote part of the uVax-side software, and subsequently have operator responsibility on the machine. Well, that was the background. What we experience now, is that when we run /bin/passwd to change passwords, the following appear on the console (ttyv0) and /bin/passwd says "/bin/passwd: I/O error". Forced Error Modifier set LBN 2305 ra0a: hard error sn02304 Section B.2.3.4 of the System Manager's Guide tells me that This error means that the data in the block is corrupted. To clear the forced error modifier, you should restore the data affected by the condition. Restoring the data causes the block to be rewritten; in rewriting the block, the hardware clears the forced error modifier. Now, what? We can copy, restore from tape, write the file through DECnet (dcp) and TCP/IP (rcp), edit the damn file with vi, every possible thing can be done with the file, except change passwords with /bin/passwd! I think I have "restored the data", and thus "caused the block to be rewritten", some 500 times just to see if the error recurred. Nope. The only time we have problems is when running /bin/passwd. If anyone can help me (us), I'd be very happy. If you need more information, feel free to write me at enag@verdande.uio.no (the affected machine) or erik@naggum.uio.no (my own machine). --Erik Naggum -- +----+ +----+ Email: erik@naggum.se --or-- erik@naggum.uio.no === | === / Snail: Naggum Software; POB 1560 VIKA; OSLO 0118; NORWAY === | === / Phone: +47-2-384-400 (office), +47-2-549-163 (home) +----+ +----+ "These are my opinions, and not those of my employees."

Reply-to: avolio@decuac.dec.com (Frederick M. Avolio) Seems to me that your disk needs to be backed up and then reformatted and restored. The section that has the most info about this in my mailual is section 4.3 Forced Error Recovery. (This is 2.2 though.) Fred
