-- Hi: I have a DEC AlphaStation 500/400 runing Tru64 4.0E.I am trying to determine if I have a disk or SCSI controller failure. Here is the background: A couple days ago the machine stopped responding via telnet. I went to the machine to find the following messages on the console log: Deferring I/O errno 5 for block (0x75aa0,0x75aa0 on device 8,17414 Deferring I?O errno 1 for block (0x400x40) on device 817408 Shortly after seeing this message I started hearing a clicking noise and noted the scsi activitly light was on. It also sounded like it was also trying to read from one of the disks. I ended up halting the machine and trying to boot from a CD. I received the following from the console prompt (>>>): ... jumping to bootstrap code (scsi activity light was on) contig-malloc: not enough aligned node memory pmr0: 95 contiguous pages available panic (cpu0): contig-malloc of in-memory sg table failed Dump No primary swap no explicit dumpdev halted CPU0 halt code5 I then tried to boot from the root disk. It sounded like the disk were spinning up but then stoped and restarted continously. The only thing I could do was to halt the machine to get back to the console prompt. Also all the devices show up if I try the "show device" command--including the SCSI controllers. So it probably is the disk(s) that have crashed but how can I verify this. And if it is indeed the disks, any suggestions on where I can purchase another? Thanks for your help Wayne
