From mboxrd@z Thu Jan 1 00:00:00 1970 From: Marc Duponcheel Date: Tue, 11 Aug 1998 00:31:54 +0000 Subject: kernel: scsi : aborting command due to timeout Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ultralinux@vger.kernel.org Hello, Running UltraPenguin 1.0.9 with CVS kernel 2.1.115 on a Sparc 5 (110Mhz) Exabyte attached to a 2nd scsi controller scsi ID 6. When writing to tape the disk on the 2nd scsi controller scsi ID 5 reports timeout problems (both with tar and dump) and system crashes (I don't find an Oops but I recall I could see one). Here is the kernel log (from linux/drivers/scsi/scsi_obsolete.c) Aug 11 00:45:40 sparc-brew kernel: scsi : aborting command due to timeout: pid 12261, scsi1, channel 0, id 5, lun 0 0x0a 15 c0 22 0 2 00 Aug 11 00:45:40 sparc-brew kernel: esp1: Aborting command Aug 11 00:45:40 sparc-brew kernel: esp1: dumping state Aug 11 00:45:40 sparc-brew kernel: esp1: dma -- cond_reg<40040010> addr Aug 11 00:45:40 sparc-brew kernel: esp1: SW [sreg<00> sstep<04> ireg<20>] Aug 11 00:45:40 sparc-brew kernel: esp1: HW reread [sreg<00> sstep ireg<00>] Aug 11 00:45:40 sparc-brew kernel: Aug 11 00:45:40 sparc-brew kernel: esp1: disconnected [tgt<06> lun<00> pphase cphase] Aug 11 00:45:40 sparc-brew kernel: SCSI disk error : host 1 channel 0 id 5 lun 0 return code = 50000 Aug 11 00:45:40 sparc-brew kernel: scsidisk I/O error: dev 08:51, sector 1425442 Note that: - this happened when I had less disks attached as well (running some 2.1.xxx kernels a while back). [which is why I no longer used the tape steamer but I now tried again] - With the 2.0.3x kernels the tape steamer worked fine. (latest 2.0.3x one I used was 2.0.30 in fact) - the disks work just fine as long as I don't use the tape. Question(s): - maybe there is some parameters I can set in order to avoid timeouts? - anybody else using an Exabyte successfully on UltraPenguin? PS: I'll make a kernel with verbose scsi reporting ... marc@sparc-brew:~ $ [bash] cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 03 Lun: 00 Vendor: QUANTUM Model: FB1080J SUN1.05 Rev: 630D Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: SEAGATE Model: ST410800N Rev: 0018 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: SEAGATE Model: ST11200N SUN1.05 Rev: 9500 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: SEAGATE Model: ST11200N SUN1.05 Rev: 9500 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 02 Lun: 00 Vendor: SEAGATE Model: ST11200N SUN1.05 Rev: 9500 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 05 Lun: 00 Vendor: SEAGATE Model: ST11200N SUN1.05 Rev: 9500 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 06 Lun: 00 Vendor: EXABYTE Model: EXB-8500SMBANXH1 Rev: 0458 Type: Sequential-Access ANSI SCSI revision: 02 marc@sparc-brew:~ $ [bash] cat /proc/scsi/esp/0 Sparc ESP Host Adapter: PROM node ffd3d20c PROM name esp ESP Model FAS100A DMA Revision Rev 2 Live Targets [ 3 6 ] Target # config3 Sync Capabilities Disconnect Wide 3 00000003 [28,04] yes no 6 00000003 [28,04] yes no marc@sparc-brew:~ $ [bash] cat /proc/scsi/esp/1 Sparc ESP Host Adapter: PROM node ffd427e8 PROM name esp ESP Model FAS236 DMA Revision ESC Rev 1 Live Targets [ 0 1 2 5 6 ] Target # config3 Sync Capabilities Disconnect Wide 0 00000018 [6f,04] yes no 1 00000018 [6f,04] yes no 2 00000018 [6f,04] yes no 5 00000018 [6f,04] yes no 6 00000008 [6f,04] yes no -- Marc Duponcheel.
