This soft copy for use by IBM employees only.
However, this only applies to the Control Workstation. The SP nodes
continue using /dev/hd7 as the primary dump device.
The following are the changes that occur when going from PSSP 1.2 to PSSP 2.1:
•
Installation over DIX
Support for installation over Ethernet type DIX has been added.
•
Customization file
firstboot.cust is now script.cust.
•
Tuning customization
A new tuning customization file called tuning.cust has been added.
•
PSSP image
bos.obj.ssp.325 is now bos.obj.ssp.41.
•
mksysb image
/usr/sys/inst.images/ssp is now /spdata/sys1/install/images.
Under PSSP 1.2, the mksysb image could be a symbolic link. This is no
longer the case. Network Installation Management (NIM) exports the file.
The mksysb image must be a regular file in the
/spdata/sys1/install/images
directory on the Control Workstation.
•
ssp.installp
ssp.installp is now pssp.installp.
•
spbootins
spbootins now has:
−
A diagnosis option,
-r diag
−
New syntax for the
-h option
•
Remote Diagnosis Support has been added in PSSP 2.1.
2.2.14 PSSP Software Strategy
The PSSP updates and fixes are available on a regular basis from IBM as PTF
sets. Some of the PSSP concepts and terminology are described as follows:
•
PSSP PTFs are available as full replacement PTFs or delta replacement
PTFs:
−
Full replacement PTFs
Full replacement PTFs means that all of the associated codes in the
affected component have been shipped in the PTF.
−
Delta replacement PTFs
Delta replacement PTFs means that only the changed files from this PTF
and prior delta replacement PTFs have been shipped in the PTF. These
PTFs will have the last full replacement PTF as a prerequisite.
•
PSSP PTF can be obtained through:
FixDist
You can obtain information about required PTFs from the Web at
http://www.rs6000.ibm.com/software/Pubs/sp_secure/status
. This page also
contains a hyperlink to the US Fixdist server to download the required PTFs.
