One reason I'd suspect you may be moving to directory rather than PROFILE
EXEC is that if you have a common PROFILE EXEC -- then everybody ends up
getting the same number, size of VDISKs which usually isn't ideal.
You might think about using some common file that lists the guests and what
resources they should have -- and then have the common PROFILE EXEC smart
enough to read this file and do the right thing for the right guest.
A few years ago, at one location, we adopted a NAMES file format and then
used NAMEFIND to get desired entries.. a sample entry:
:nick.linux01 :user.linux01 :node.vmlinux1 :ip.192.168.20.3
:vdisk.2/256 :cpu.1 :vswitch.vswitch1 :nic.500 ...............
Essentially - a control file that each Linux guest can read in the PROFILE
EXEC and issue the corresponding commands (DEFINE, COUPLE, SWAPGEN,
whatever) to fit the definition for itself.
Some people might see this as an unnecessary layer/point of failure and want
to use the directory to define everything <shrug> Don't really want to
start that religious war ;-) IPLing CMS gives you the opportunity to apply
logic to the setup of your virtual machine before IPLing Linux -- even pass
data to it (using the punch for example). So I prefer that flexibility..
