Operating Systems AIX Changing AIX LUN paths Post 302994008 by rbatte1 on Friday 17th of March 2017 11:37:55 AM

The LUN that AIX recognises will be based on the serial number it is presented with. I no longer have AIX available, but I think you can see it in the Z00 or Z01 line in lscfg -vl hdisk7 or whatever.

You should be able to add the new links in from the SAN and get wider output from lsvpcfg

If you can, then you can delete the old hdisks and remove the old SAN definitions. This way, you don't need to take them offline.
Obviously, don't start removing things until you are certian that the new hdisks (discovered with cfgmgr -S) are merged into the existing vpaths.

Make sure that you remove the old hdisks before you try to remove the LUN at the SAN end or you will get lots of hardware failure messages.


I hope that this helps.

NAME
remove - remove file SYNOPSIS
#include <stdio.h> int remove(const char *path); DESCRIPTION
The remove() function causes the file or empty directory whose name is the string pointed to by path to be no longer accessible by that name. A subsequent attempt to open that file using that name will fail, unless the file is created anew. For files, remove() is identical to unlink(). For directories, remove() is identical to rmdir(). See rmdir(2) and unlink(2) for a detailed list of failure conditions. RETURN VALUES
Upon successful completion, remove() returns 0. Otherwise, it returns -1 and sets errno to indicate an error. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
