PSDL Installation Procedure
During a flash download, the system downloads the contents of a
PSDL/PSWV file to an M3900 set. This PSDL Installation Procedure can be
used to load a new PSDL/PSWV file on the system in place of totally
reinstalling system software. If there are concerns about system downtime in
regards to performing software upgrades in cases where only a new
PSDL/PSWV file is needed, this process allows the replacement of the
PSDL/PSWV file only.
Installation procedures for Options 61C, 81, and 81C
Note: This procedure does not include instructions on general software
installation nor does it cover installing new IODU/C cards. To use this
procedure, you must already be equipped with IODU/C cards that have
the X11 software installed.
Use the parallel reload procedures to convert from one X11 release of PSDL
files to a later release, or to change the PSDL file within the same X11 release.
Parallel reloads can be done from either CPU. For the purposes of this
document, we begin with CPU 0.
