Hi List,
I have a query. I am using SBS 2003, Veritas 9.1, and a compaq dlt 8000 drv on a scsi ultrawide adapter. Since an attempted install of SP2 for SBS my Backups have been remarkably slow. Along with this, Exchange Broke, WMI was completey busted apart, and the IIS metabase was knackered. However, after fixing IIS, WMI & exchange I had kinda hoped that this would solve my backups, but alas, it hasn't. As an example, I am getting write speeds of 38MB/min, and when backing up 80GB, this is taking forever. I ran Process Monitor and get the following repeatedly in the logs:
5677 58:00.4 bengine.exe 5128 DeviceIoControl \Device\Tape0 SUCCESS Control: IOCTL_SCSI_PASS_THROUGH_DIRECT
5698 58:00.4 bengine.exe 5128 DeviceIoControl \Device\Tape0 FAST IO DISALLOWED Control: IOCTL_SCSI_PASS_THROUGH_DIRECT
5699 58:00.4 bengine.exe 5128 DeviceIoControl \Device\Tape0 SUCCESS Control: IOCTL_SCSI_PASS_THROUGH_DIRECT
5719 58:00.4 bengine.exe 5128 DeviceIoControl \Device\Tape0 FAST IO DISALLOWED
So to summarise, every two lines there is one " FAST IO DISALLOWED", and then "SUCCESS Control: IOCTL_SCSI_PASS_THROUGH_DIRECT".
This is really causing me issues so any help is much appreciated. I hope I have made sense, but if not give me a shout and I can provide more info when requested.
Oh, I forgot to add - my
suspicions are that this could be related to the SCSI controller - does anyone have any pointers?
TIA
J
