Hello, I've been getting various errors in /var/log/messages indicating that there may be problems with my scsi subsytem. I have 4 devices ( Controller + 3 drives). But until now they have not been service impacting -- last nights failed attempt at an online update was an exercise in fustration. In any case, I need to fix the problem, but am not sure if it is the adaptec controller card, or one the drives that are the root of the problem. Thanks in advance, Laszlo I've included some of the logs of last nights session below: <taken from /var/log/messages> Apr 13 19:37:08 www kernel: VM: killing process rpm Apr 13 19:38:02 www kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) Apr 13 19:38:02 www kernel: VM: killing process rpm Apr 13 19:38:55 www kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) Apr 13 19:38:55 www kernel: VM: killing process rpm Apr 13 19:39:50 www kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) Apr 13 19:39:50 www kernel: VM: killing process rpm Apr 13 19:40:46 www kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) Apr 13 19:40:46 www kernel: VM: killing process rpm Apr 13 19:42:31 www kernel: scsi0:0:0:0: Attempting to queue an ABORT message Apr 13 19:42:31 www kernel: scsi0: Dumping Card State in Data-out phase, at SEQADDR 0x8c Apr 13 19:42:31 www kernel: ACCUM = 0x0, SINDEX = 0x12, DINDEX = 0x1f, ARG_2 = 0x1d Apr 13 19:42:31 www kernel: HCNT = 0x0 SCBPTR = 0x8 Apr 13 19:42:31 www kernel: SCSISEQ = 0x12, SBLKCTL = 0xa Apr 13 19:42:31 www kernel: DFCNTRL = 0x2c, DFSTATUS = 0x88 Apr 13 19:42:31 www kernel: LASTPHASE = 0x0, SCSISIGI = 0x4, SXFRCTL0 = 0x80 Apr 13 19:42:31 www kernel: SSTAT0 = 0x0, SSTAT1 = 0x2 Apr 13 19:42:31 www kernel: STACK == 0x8a, 0x64, 0x165, 0x8a Apr 13 19:42:31 www kernel: SCB count = 92 Apr 13 19:42:31 www kernel: Kernel NEXTQSCB = 90 Apr 13 19:42:31 www kernel: Card NEXTQSCB = 39 Apr 13 19:45:57 www kernel: QINFIFO entries: 39 44 35 85 54 59 61 51 15 14 91 23 40 Apr 13 19:45:57 www kernel: Waiting Queue entries: Apr 13 19:45:57 www kernel: Disconnected Queue entries: 23:53 30:19 29:46 31:37 17:38 12:48 Apr 13 19:45:57 www kernel: QOUTFIFO entries: Apr 13 19:45:57 www kernel: Sequencer Free SCB List: 22 13 18 24 0 15 21 19 27 25 6 26 1 14 7 16 28 5 3 11 10 2 20 9 4 Apr 13 19:45:57 www kernel: Sequencer SCB Info: 0(c 0x60, s 0x87, l 0, t 0xff) 1(c 0x60, s 0x47, l 0, t 0xff) 2(c 0x60, s 0x7, l 0, t 0xff) 3(c 0x60, s 0x7, l 0, t 0xff) 4(c 0x60, s 0x7, l 0, t 0xff) 5(c 0x60, s 0x47, l 0, t 0xff) 6(c 0x60, s 0x47, l 0, t 0xff) 7( c 0x60, s 0x7, l 0, t 0xff) 8(c 0x60, s 0x47, l 0, t 0x2a) 9(c 0x60, s 0x7, l 0, t 0xff) 10(c 0x60, s 0x7, l 0, t 0xff) 11(c 0x60, s 0x7, l 0, t 0xff) 12(c 0x64, s 0x47, l 0, t 0x30) 13(c 0x60, s 0x87, l 0, t 0xff) 14(c 0x60, s 0x47, l 0, t 0xff) 15(c 0x60, s 0x47 , l 0, t 0xff) 16(c 0x60, s 0x47, l 0, t 0xff) 17(c 0x64, s 0x47, l 0, t 0x26) 18(c 0x60, s 0x47, l 0, t 0xff) 19(c 0x60, s 0x7, l 0 , t 0xff) 20(c 0x60, s 0x7, l 0, t 0xff) 21(c 0x60, s 0x87, l 0, t 0xff) 22(c 0x60, s 0x47, l 0, t 0xff) 23(c 0x64, s 0x87, l 0, t 0 x35) 24(c 0x60, s 0x7, l 0, t 0xff) 25(c 0x60, s 0x7, l 0, t 0xff) 26(c 0x60, s 0x7, l 0, t 0xff) 27(c 0x60, s 0x7, l 0, t 0xff) 28( c 0x60, s 0x87, l 0, t 0xff) 29(c 0x64, s 0x47, l 0, t 0x2e) 30(c 0x64, s 0x47, l 0, t 0x13) 31(c 0 Apr 13 19:45:57 www kernel: 64, s 0x47, l 0, t 0x25) Apr 13 19:45:57 www kernel: Pending list: 40(c 0x60, s 0x47, l 0), 23(c 0x60, s 0x47, l 0), 91(c 0x60, s 0x47, l 0), 14(c 0x60, s 0x 47, l 0), 15(c 0x60, s 0x47, l 0), 51(c 0x60, s 0x47, l 0), 61(c 0x60, s 0x47, l 0), 59(c 0x60, s 0x7, l 0), 54(c 0x60, s 0x7, l 0), 85(c 0x60, s 0x7, l 0), 35(c 0x60, s 0x47, l 0), 44(c 0x60, s 0x47, l 0), 39(c 0x60, s 0x47, l 0), 53(c 0x60, s 0x87, l 0), 19(c 0x 60, s 0x47, l 0), 46(c 0x60, s 0x47, l 0), 42(c 0x60, s 0x47, l 0), 37(c 0x60, s 0x47, l 0), 38(c 0x60, s 0x47, l 0), 48(c 0x60, s 0 x47, l 0) Apr 13 19:45:57 www kernel: Kernel Free SCB list: 73 12 66 5 88 52 49 32 30 77 25 67 63 27 62 86 7 79 72 75 22 16 56 50 33 76 81 84 45 55 47 10 2 43 13 41 74 8 9 34 0 28 4 11 17 1 24 18 57 29 36 65 6 60 82 58 20 68 89 31 69 80 70 71 78 64 26 87 83 3 21 Apr 13 19:45:57 www kernel: DevQ(0:0:0): 0 waiting Apr 13 19:45:57 www kernel: DevQ(0:3:0): 0 waiting Apr 13 19:45:57 www kernel: DevQ(0:4:0): 0 waiting Apr 13 19:45:57 www kernel: DevQ(0:8:0): 0 waiting Apr 13 19:45:57 www kernel: scsi0:0:0:0: Cmd aborted from QINFIFO <continues.....>
