Changing AIX LUN paths
Hello,

Looking for some guidance to changing how an AIX 6.1 server sees its luns. Presently they're connected via 1GB iscsi but I want to change it to 4GB fiber channel. Anyone done this before and if so is it an easy step?

I'm thinking this can be done in this order:
  1. unmount the filesystems
  2. varyoffvg vg
  3. make the changes on the storage system (EMC)
  4. cfgmgr
  5. varyonvg vg
  6. mount the filesystems

I've never done this before so I'm hoping its that simple but IBM is never that simple.

Any help is much appreciated.

virtual-filesystems

virtual-filesystems(7)					 Miscellaneous Information Manual				    virtual-filesystems(7)

NAME

       virtual-filesystems - event signalling that virtual filesystems have been mounted

SYNOPSIS

       virtual-filesystems [ENV]...

DESCRIPTION

       The  virtual-filesystems  event	is  generated  by  the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
       mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so	in  parallel  with
       other activity.

       This event is typically used by services that must be started in order to mount other filesystems.  When this event occurs, common filesys-
       tems such as /usr may not be mounted.  For most normal services the filesystem(7) event is sufficient.

EXAMPLE

       A service that wishes to be running once virtual filesystems are mounted might use:

	      start on virtual-filesystems
