It's a Viglen XX server with two 7880 chips on the motherboard. It has three Fujitsu M2934 wide drives on each scsi bus, connected thus: 7880 -> (da0) 2934 : (da1) 2934 : (da2) 2934 : CDROM : TAPE 7880 -> (da3) 2934 : (da4) 2934 : (da5) 2934 I have the system on da0 and want to make a ccd of drives da1 and da3. However, when I try to newfs the newly created ccd... # newfs /dev/rccd0a Warning: 1280 sector(s) in last cylinder unallocated /dev/ccd0a: 17013504 sectors in 4154 cylinders of 1 tracks, 4096 sectors 8307.4MB in 260 cyl groups (16 c/g, 32.00MB/g, 7936 i/g) super-block backups (for fsck -b #) at: n1, n2, n3, n4 etc. Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 125 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 125 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 124 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 124 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 122 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 122 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 121 etc. etc. until Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 64 Nov 10 15:48:55 titan /kernel: (da3:ahc1:0:4:0): tagged openings now 63 Nov 10 15:48:58 titan /kernel: (da2:ahc0:0:1:0): tagged openings now 2 Nov 10 15:48:58 titan /kernel: (da2:ahc0:0:1:0): tagged openings now 2 Then the block numbers stop. First time it happened I thought the machine had hung, so I sshed in and rebooted it. Upon the console appeared: syncing disks x y x ... giving up ahc0: data parity error detected during address or write data phase Next time I tried it, I noticed that it hadn't actually hung, but was still printing a block number every couple of minutes or so. I killed it and after a few minutes got my prompt back. Then the same newfs command worked perfectly? Any ideas what caused that? Cheers.
