CDOM and LDOM config
If your server doesn’t have a CDOM, you could create one by running something like this (create_config.ksh):
ldm add-vdiskserver primary-vds0 primary ldm add-vconscon port-range=5000-5100 primary-vcc0 primary ldm add-vswitch net-dev=igb0 primary-vsw0 primary ldm add-vswitch net-dev=nxge0 primary-vsw1 primary ldm set-vcpu 4 primary ldm set-memory 1g primary ldm add-config initial ldm list-config
Reboot the server.
Now let’s say you want to create an LDOM in that server, login to the cdom and do something like this (create_myldom.ksh):
ldm add-domain myldom ldm set-vcpu 16 myldom ldm set-memory 13G myldom ldm add-vnet vnet1 primary-vsw0 myldom ldm add-vnet vnet2 primary-vsw1 myldom ldm add-vdsdev /dev/dsk/
c0t600601605A203100A44CDC74C08 2E211d0s2 vol2@primary-vds0 ldm add-vdisk vdisk0 vol2@primary-vds0 myldom ldm bind myldom ldm set-var auto-boot?=true myldom ldm start-domain myldom
find missing lines
If you want to find the lines “b” is missing from “a”
# fgrep -vxf b a

fullscreen vs windowed SheepShaver (MacOS classic emulator)
The SheepShaver preferences file is in your user’s home, for instance mine is in /Users/robertodircio/.sheepshaver_prefs
the setting to enable fullscreen is:
screen dga/0/0
to have windowed mode, change that to:
screen win/800/600
Clear linux cached memory
if you want to clear the linux cached memory run “echo 3 > /proc/sys/vm/drop_caches”
