hi, I try to get an older JBOD (Infrotrend A16U-G242) working with a 53c1030 PCI-X Controller (from Sun) as spooldisk for Bacula, but it fails: [...] Jun 6 12:02:08 ext-backup kernel: [ 1710.355096] sd 6:0:0:0: [sdc] Unhandled error code Jun 6 12:02:08 ext-backup kernel: [ 1710.355101] sd 6:0:0:0: [sdc] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK Jun 6 12:02:08 ext-backup kernel: [ 1710.355107] sd 6:0:0:0: [sdc] CDB: Write(10): 2a 00 80 00 20 40 00 04 00 00 Jun 6 12:02:08 ext-backup kernel: [ 1710.355120] end_request: I/O error, dev sdc, sector 2147491904 [...] Jun 6 12:02:10 ext-backup kernel: [ 1712.352461] end_request: I/O error, dev sdc, sector 2147500096 Jun 6 12:02:10 ext-backup kernel: [ 1712.352598] Buffer I/O error on device sdc, logical block 268436488 Jun 6 12:02:10 ext-backup kernel: [ 1712.352715] lost page write due to I/O error on sdc Jun 6 12:02:10 ext-backup kernel: [ 1712.352718] Buffer I/O error on device sdc, logical block 268436489 Jun 6 12:02:10 ext-backup kernel: [ 1712.352835] lost page write due to I/O error on sdc Jun 6 12:02:10 ext-backup kernel: [ 1712.352837] Buffer I/O error on device sdc, logical block 268436490 [...] Jun 6 12:02:10 ext-backup kernel: [ 1712.361984] mptbase: ioc0: LogInfo(0x11010000): F/W: bug!

If I let Bacula write over the same controller to our autochanger, there is no problem (using the local SATA disks as spooldrive). I've search also for a newer firmware, but there was no one available on the LSI website.
