None that I know of
if I install the rscd agent with the silent install with this nsh_install_defaults file:
I see that RSCDHOME gets set to /appl/bsa/bmc/BladeLogic/NSH.
When I use the rpm and use this command to install it:
rpm -Uiv --prefix /appl/bsa/bmc/BladeLogic ??SOURCE??
I see that RSCDHOME gets set /appl/bsa/bmc/BladeLogic/RSCD.
So there seems to be a difference in setup between both methods. Is that for a specific reason?
What's the preferred method for installation according BMC?
There’s no preferred method. And it doesn’t matter what directory it gets installed in.
