Does anyone have a useful Linux running on zSeries that is less that 24MB with OSA? With LCS? It looks like OSA is a good chunk of code.
I put together a SuSE SLES8 SP2 mimum system (no graphics) and played a bit with memory size. I manipulated mem=??m in /etc/zipl.conf. Some conclusions: 1 - I could not ipl in 8m - I got a kernel panic 2 - I could IPL with 12m, but it did not load the OSA code. 3 - I could IPL at 24m and load the OSA. After starting an ssh login sessions and mounting 2 NFS mounts, there was 3372 bytes, on the swap volume. 4 - at 32m, the swap usage when to zero. At 24m, I could login with ssh and mount 2 nfs volumes. The configuration was for 2 CP. There was not a large variance between LPAR and EC (about an additonal 68 useable bytes under LPAR). SuSE wants to start the following processes: init migration_CP (1 per CP) kmcheck kvventd ksoftirqd_CP kswapd bdflush kupdated kinoded mdrecoveryd kreiserfsd lvm-mpd qethsoft syslogd klogd portmap sshd master pickup qmgr atd cron nscd (7 copies) login Regards, Jim Linux S/390-zSeries Support, SEEL, IBM Silicon Valley Labs t/l 543-4021, 408-463-4021, [EMAIL PROTECTED] *** Grace Happens ***
