I’ve a tape device installed on SLES 11 SP4, connected via SCSI. The device works at startup, but after 2-3 weeks it stop working. With previous version of SLES, running rescan-scsi-bus.sh --forcerescan I was able to recover the tape, now the same commad doesn’t restore the tape. Previous I needed to run rescan-scsi-bus two time: [LIST] the first remove the tape (the tepe was seen by rescan-scsi-bus, but not by tape command like mt -f /dev/nst0 status) [\*] [/LIST] rescan-scsi-bus.sh --forcerescan Syncing file systems Scanning SCSI subsystem for new devices and remove devices that have disappeared Scanning host 0 for SCSI target IDs 0 1 2 3 4 5 6 7, all LUNs Scanning host 1 for SCSI target IDs 0 1 2 3 4 5 6 7, all LUNs Scanning for device 1 0 0 0 …sg0 changed: INQUIRY failed REM: Host: scsi1 Channel: 00 Id: 00 Lun: 00 DEL: Vendor: HP Model: Ultrium 2-SCSI Rev: T65D Type: Sequential-Access ANSI SCSI revision: 05 Scanning host 2 for SCSI target IDs 0 1 2 3 4 5 6 7, all LUNs Scanning host 3 for SCSI target IDs 0 1 2 3 4 5 6 7, all LUNs Scanning for device 3 0 0 0 … OLD: Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: HL-DT-ST Model: DVD-RAM GH40L Rev: LA01 Type: CD-ROM ANSI SCSI revision: 05 0 new or changed device(s) found. 0 remapped or resized device(s) found. 1 device(s) removed. [1:0:0:0] [LIST] [\*] the second one restored the device. [/LIST] With SLES11 SP4 no more. The only action I have is restarting the server. Can I have some suggestions in order to solve my problem? Thanks, Fabrizio ---
