Use symbolic links to assign abbreviated standard device names. To create a link between the character-special device name and another filename, use the link command (usually ln).
To verify that both the devices and the links exist, execute the command ls -l (ls -lg on BSD) on your device directory. The following example shows links to raw devices. If your operating system does not support symbolic links, hard links work as well.
% ls -lg crw-rw--- /dev/rxy0h crw-rw--- /dev/rxy0a lrwxrwxrwx /dev/my_root@->/dev/rxy0h lrwxrwxrwx /dev/raw_dev2@->/dev/rxy0a
Extended Parallel Server requires standard device names across all coservers.
