It seems like we get a lot of VMS questions here, which probably doesn't really fall directly under the list rules. I'm guilty of it too. But there's so much knowledge here, it's hard not to ask. If anyone can point me in the direction of an active VMS mailing list, I'll ask my VMS questions there instead. And if there's not one, I'd consider setting one up if there happens to be any mailing list software that works with Exchange Server 2000. ----- I've got my ARCHIVE Python (model 4326) DDS-2 drive connected to my MV3100. It is connected to that machine only (I don't have it dual-connected, as discussed in another message thread) and it's on my 2nd SCSI controller chain. When I first boot the system, the first restore I do from tape I get this message: $ backup mkb100:rob/save *.* %MOUNT-I-MOUNTED, ROB mounted on _BOB$MKB100: %BACKUP-E-READERRS, excessive error rate reading MKB100:[000000]ROB.; -SYSTEM-F-CTRLERR, fatal controller error %BACKUP-I-OPERSPEC %BACKUP-I-OPERASSIST, operator assistance has been requested I then get "fatal controller error" messages whenever I try to access the drive, until I turn it off and back on. After the above erorr, the device shows 102 errors in SHOW DEVICE. Once the drive is turned off and back on, it works fine from then on, with no problems. If I boot the system, then turn the drive off, and back on, I *still* get this message for the first restore I do. Then I turn the drive off and back on, and all is OK. If the first operation I do after booting is a backup TO tape, it goes fine with no problems. But then when I try to do a restore from tape, I still get the above error. I've updated the drive's firmware to what I believe to be the latest (28388-XXX V5.AQ). Right now I have the drive in an external enclosure to test it. I was going to mount it internally in the MV3100, but if I have to power the drive down to make it work, then internal mounting is not possible. Could it be a SCSI termination problem? The drive works flawlessly on my PC. Thanks, - Bob
