I've just noticed that a server I support has been logging SCSI errors every Friday at about the same time. It's just a quick blip of error messages, then on to normal business: Nov 29 20:31:25 esd-tls01 kernel: SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 28000002 Nov 29 20:31:25 esd-tls01 kernel: Current sd08:07: sense key Hardware Error Nov 29 20:31:25 esd-tls01 kernel: Additional sense indicates Internal target failure Nov 29 20:31:25 esd-tls01 kernel: I/O error: dev 08:07, sector 92510 Nov 29 20:31:25 esd-tls01 kernel: sym53c896-0-<0,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 15) Nov 29 20:31:29 esd-tls01 kernel: SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 28000002 Nov 29 20:31:29 esd-tls01 kernel: Current sd08:07: sense key Hardware Error Nov 29 20:31:29 esd-tls01 kernel: Additional sense indicates Internal target failure Nov 29 20:31:29 esd-tls01 kernel: I/O error: dev 08:07, sector 92510 Nov 29 20:31:29 esd-tls01 kernel: sym53c896-0-<0,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 15) Here's the output of "cat /proc/scsi/scsi" Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: DGHS09Y CLAR09 Rev: 1A1A Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: SEAGATE Model: ST39102L CLAR09 Rev: AV05 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: ESG-SHV Model: SCA HSBP M8 Rev: 0.05 Type: Processor ANSI SCSI revision: 02 Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: DGC Model: RAID 5 Rev: 0847 Type: Direct-Access ANSI SCSI revision: 04 Host: scsi3 Channel: 00 Id: 00 Lun: 01 Vendor: DGC Model: RAID 5 Rev: 0847 Type: Direct-Access ANSI SCSI revision: 04 I've looked at my cron jobs, and I see anything that runs about that time on Fridays. One other weird thing... The console is unresponsive. I can't log in on tty1. The other tty's seem fine. I tried killing the process on tty1 so it would respawn (which it did), but that did not make tty1 usable. Any ideas? TIA, Bill
