So My LTO4 drive had dodgy tape heads. I have been refunded and managed to obtain another couple of HP Storageworks 1760 drives. I am still experiencing odd problems though. These are my drives: HP DAT72] HP Storageworks 232 LTO1 HP Storageworks 448 LTO2 HP Storageworks 920 LTO3 HP Storageworks 1760 LTO4 x2 All of them are SCSI LVDS drives. The DAT72 is 40mbps the LTO1 and 2 are 160mbps and the LTO3 and 4 are 320mbps. If I connect the DAT72 / LTO1 / LTO2 all 3 work fine. If I add in the LTO3 or either LTO4 drive, the LTO3 or 4 drives do not work (They start writing then suddenly stop dead and rewind the tape and I cannot terminate the process, tar / mt or HP L&TT, even with kill -9 unless I reboot). If I connect up one LTO4 or just the LTO3 on its own, with no other drives on the SCSI bus, then they work fine and pass all the tests in the HP L&TT program. So I would think that the drives themselves are OK because they all appear to work fine individually. If I connect up an LTO4 drive and the LTO3 drive both do not work (same problem as before). If I connect an LTO4 drive with the LTO2 drive, the LTO4 drive will not work (same problem) but the LTO2 does. The same happens if I connect the LTO3 drive with the LTO2 drive, the LTO3 drive will not work (same problem) but the LTO2 does. The weird thing is that for over a year I used my lto3 drive at the same time as the lto2 drive with no problems. If I connect both LTO4 drives they do not work (again, same problem). I have replaced the controller card and SCSI cable and also the terminator but none of these made a difference to the problem. I have also checked the power supply and all of the voltages are as expected and it is only at 12% load. Anyone have any ideas what is happening?
