DDS DRIVE

Nobody's Hero — Thu, 19 Dec 2002 14:25:49 GMT

Looks like I had a faulty terminator if anybody remembers my tape drive problem yesterday. I removed the terminator and now the drive works, go figure. Well during the troubleshooting period I changed the scsi id, now I have a floating 'no_hw' state device. Can I use rmsf to remove this?
See below. I want to remove 2m.

Hi,

rmsf can only help you to remove the special files. You will need to reboot the server to get rid of the NO_HW status of this path in the kernel.

Robert,

Since it's not really there, it sure sounds safe to me. I would also think that the next reboot would clear it.

Hi,

you could use rmsf -a "dev" this should remove the device and and associated files

You can use rmsf to remove the /dev/rmt files, but the only way to get rid of a NO_HW device is to reboot the system.

Really?

So what would be the outcome of

rmsf -H 0/7/0/1.4.0 -k

?
