Posted by tommaco (tommaco), 22 December 2006I'm attempting to create a small GUI using SpecTcl which would simplify mounting and unmounting scsi drives. Currently I am using the command
exec echo "scsi add-single-device 1 0 1 0" > /proc/scsi/scsi
exec echo "scsi remove-single-device 1 0 1 0" > /proc/scsi/scsi
The add part will work like this, but unmounting the drive brings up and error on how the drive does not exist. The line still works, and will unmount but the error causes the rest of the function to quit out.
I've narrowed it down to exec which I seem forced to use while in tcl. Any help on this would be greatly appreciated.
Posted by admin (Graham Ellis), 22 December 2006You can probably catch the error so that the function doesn't quit. There's an example of catch here
