DAT "AUTO"

[Nobody's Hero]

I hate to be a pest.
I created the device file like Shiju said.
It created /dev/rmt/0m_nocomp

When I try to use this device is says. "output file /dev/rmt/0m_nocomp is not in a valid device state"

any ideas, sorry to be a pest, but this is over my head.

What does ..
# lssf /dev/rmt/0m_nocomp
says ?

If it outputs something like ..."DDS3 density unknown" then that's where your problem is. The density "DDS3" is not being understood by the mksf command. I think the patches list that Shiju provide would deal with this.

However why don't you try using "-b DDS1" instead because DDS1 device driver is always in uncompress mode. Even though you defined DDS1 in the driver creation, it's the media that defines which format the drive would write, not the device file. So you're still ok.

The -b DDS1 option worked fine. Now Im using a DDS# tape drive with DDS1 blocking. Exactly what I needed. Thanks everyone..again and again.
