It is recommended that you use symbolic links to assign abbreviated standard device names for each raw disk device. If you have symbolic links, you can replace a disk that has failed with a new disk by assigning the symbolic name to the new disk.
To create a link between the character-special device name and another filename, use the UNIX link command (usually ln).
Execute the UNIX command ls -l (ls -lg on BSD) on your device directory to verify that both the devices and the links exist. The following example shows links to raw devices. If your operating system does not support symbolic links, you can use hard links.
% 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 on UNIX. Use standard naming conventions for the chunk paths.
