Probably all of your problems could be for this. I Recommend plug a Single Ended SCSI Controller (The simplest you have) and connect the tape.<BR /><BR />Regards<BR /><BR />Jorge Thu, 12 Jun 2003 10:11:44 GMT Jorge Pons 2003-06-12T10:11:44Z https://community.hpe.com/t5/netservers/hp-netserver-lhii-errors-on-scsi-tape-device/m-p/2995611#M4864 I have an HP Netserver LHII with an internal HP Surestore DAT24 tape unit.<BR />The tape is connected to one of the onboard SCSI controllers which are part of the Hot-swap subsystem. This has two SCSI ports each with two 9Gb SCSI drives.<BR /><BR />The systems has been running for over 4 years, though during that time we have had the tape unit replaced almost annually. Recently however the symptom has recurred all too frequently.<BR /><BR />Even when the tape is not in use, the system event log occasionally displays the error Source: aic78xx, Event 9, which gives "The device, \Device\ScsiPort0, did not respond within the timeout period" From time to time this is accompanied by error Source: aic78xx, Event 11, which gives "The driver detected a controller error on \Device\ScsiPort0.<BR /><BR />We also use Arcserve v6.5 for backup. Its activity log also shows errors "E6300, Windows NT SCSI PORT ERROR" but not every time.<BR /><BR />More often than not, this occurs during a backup and so the backup fails, but yesterday and today, the backup seemed to work fine, and the errors occured when the tape unit was not in use.<BR /><BR />We have replaced the tape and the problem goes away for a while. Recently we replaced the ribbon cable and that seemed fine for about a week. Couldit be the SCSI controller?<BR /><BR />The two hard drives that share ScsiPort0 do not appear to be affected and carry on regardless. <BR /><BR />Can anyone suggest what might be the possible cause, please?<BR /> Thu, 12 Jun 2003 09:44:51 GMT https://community.hpe.com/t5/netservers/hp-netserver-lhii-errors-on-scsi-tape-device/m-p/2995611#M4864 Robert Varley 2003-06-12T09:44:51Z https://community.hpe.com/t5/netservers/hp-netserver-lhii-errors-on-scsi-tape-device/m-p/2995612#M4865 Hi<BR /><BR />The Recommendation with Hot-Swap Bus is connect only Hot-Swap devices.<BR />Is NOT RECOMMEND connect other devices, like Tapes.
