Release 4.5, Revision 2
1. Download the patch, kaio-2.4.18-1.tar, from the HPSS website
(
http://www4.clearlake.ibm.com/hpss/support/patches/kaio-2.4.18-
1.tar
).
2. Untar the downloaded file.
% tar -xvf kaio-2.4.18-1.tar
3. Copy kaio-2.4.18-1 (the patch file) to /usr/src.
% cp kaio-2.4.18-1 /usr/src
4. Change directory to /usr/src/linux-2.4.18 (or the root of your 2.4.18 kernel tree).
% cd linux-2.4.18
5. Apply the patch
% patch -p1 < ../kaio-2.4.18-1
6. Run make config and answer yes when questioned about AIO support. The default value
of 4096 should be sufficient for the number of system-wide AIO requests. At this time, you
should also configure the kernel to support your disk or tape devices. If tape device access
is required, be sure to also enable the kernel for SCSI tape support.
7. Remake the dependencies
% make dep
8. Build a new kernel
% make bzImage
9. Copy the bzImage to /boot, add a new stanza to the /etc/lilo.conf file, and run /sbin/lilo.
% cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.18-kaio
% vi /etc/lilo.conf
% /sbin/lilo
10. If you need to rebuild the HPSS Mover, make a link from /usr/src/linux/include/linux/aio.h
to /usr/include/linux/aio.h.
% cd /usr/include/linux
% ln -s /usr/src/linux/include/linux/aio.h
