How to change terminal device file ?

[Sir T S S]

Dear experts,
we have a clustered environment,
one of our binary is tied to /dev/tty2a8 on node 1. We are trying to failover to node 2, but /dev/tty2a8 is not created, we have /dev/tty4a8 instead. is there any way to change the tty4a8 to tty2a8 or somehow make a linkage?

[Stephen Keane]

# ln -s /dev/tty4a8 /dev/tty2a8
should do it.

HP-UX doesn't care what the name of the device is, provided the major/minor numbers are OK.

Hi,
after you have created the link make sure you have the access priviledges you need.
ls -l /dev/tty2a8
If you have not, remove the link, change your umask and then recreate the link.

The other solution would be to change the instance number of the multi-serial device... Not the easiest solution, but it is the neatest, especially if you add a new device in the nodes which would create a tty4a8 on node 1.

Something else to keep in mind: what's behind the tty2a8 on node 1? Is this also accessable on node 2?

Hi Peter,

Do u mean by changing it all to rwxrwxrwx , ? i try the command cu -l /dev/tty2a8 ( a link created on node 1 ) but it gave error. pls refer to attachment . anyone can advise on this.

sorry all, attachment is here..

Hi Elmar,

Any step to change to instance number as u suggested?

[Elmar P. Kolkman]

Take a look at ioinit. There should be multiple documents on the ITRC or net to use it to re-assign instance numbers to hardware.
