If you've been following the AIX 1.3 saga so far,
you may be wondering, "How big are all of those optional IBM Licensed Program
Products?" Well, I'll try to answer that question.
First, a review: The AIX 1.3 installation process
will create six minidisks in the AIX data partition, and the size of the
AIX data partition is the concatenation of the size of those six minidisks.
An AIX boot partition is also created, and that is a little larger than
3MB. If you accept the default hostname of aixps2, the names of the
filesystems are: /u, /aixps2, /, /aixps2/tmp. The page minidisk
and the
dump minidisk do not have filesystems on them, they are used for virtual
memory paging activity and system core dumps, respectively.
Default Install
Using the SCSI boot diskettes with the Install diskette,
the default sizes of the minidisks are as follows:
Disk
Size in 1K blocks Number of inodes
/u
9824
982
/aixps2 7704
770
/
42000
4200
page
4000
* (used for swapping)
dump
4000
* (no files unless a dump occurs)
/aixps2/tmp 5804
580
With this configuration, you would need at least an 80MB hard drive
(don't forget the space required for the AIX boot partition and your system
partition). The smallest drive I was using was 540MB.
1GB HD Install
After I finished Louis' "master drive", I decided to re-do
my 1GB SCSI drive, and allocated the minidisks as follows:
Disk
Size in 1K blocks Number of FILES
/u
307200
30720
/aixps2 65536
6553
/
307200
30720
page
131072
dump
49152
/aixps2/tmp 102400
10240
This gives 300MB for user files (/u), 64MB for "system"
files (/aixps2), 300MB for programs, system data files (/), 128MB for paging
space (with 32MB of RAM, this should be more than enough), 48MB for dump
space, and 100MB for system temp files (/aixps2/tmp).
After the base installation (all of the Basic Operating
System diskettes loaded, and the system rebooted), here's how the file
system space looked:
Filesystem Total Blocks
Blocks free Inodes used
/u
291832 291828
3
/aixps2 62248
60188 287
/
291832 276172
1149
/aixps2/tmp 97272
97268 5
You can see the effect of system overhead (mostly space
for the inodes) on the total number of blocks available for use in each
filesystem, and you'll note that most of the files (and blocks consumed)
were in the root filesystem.
LPP Filesystem Space Requirements
Here's a picture of the filesystems after I installed all of the optional
LPPs that I had available:
Filesystem Total Blocks
Blocks free Inodes used
/u
291832 291828
3
/aixps2 62248
52856 537
/
291832 188152
9182
/aixps2/tmp 97272
97192 12
At this point, I had five "old" system kernels in the /aixps2
filesystem, each consuming about 1.6MB, so if I deleted all of the "dead"
kernels, I could boost the free space in /aixps2 by almost 8000 blocks.
Hence, the installed LPPs took almost all of their space out of the root
filesystem, to the tune of 86MB. Next, I will list the number of
blocks of the root filesystem consumed by the installation of each LPP:

If you're wondering what happened to the X.25 subsystem
support, it turns out that the 2nd diskette image for X.25 is actually
another copy of the 2nd diskette image for TCP/IP... so I could not successfully
install X.25. The files that loaded from the first diskette consumed
1540 blocks. Also, the Advanced Development Tools actually fit on
5 diskettes, the 6th image in that set is SCCS (Source Code Control System).
