John,

Why? After booting the vxWorks image, the only disk access that deserves
to be called fast is NFS.

(I assume you're using vxWorks 5.2 for the following ... I don't know if
Tornado works differently.)

This is getting and starting the vxWorks image. How this is done depends on
the flags and ftp password settings in the IOC's nvram. You may use
bootp/tftp, ftp, rsh access.

This is getting the symbol table. Note: The symbol table ist _ALWAYS_
loaded via rsh access, no matter which way the binary is loaded.
It seems that while opening the rsh to apis one of the the shell init
scripts (~/.cshrc ~/.zshenv ~/.profile /etc/cshrc /etc/profile ...) leads
to an error before the shell can execute what the IOC wants it to:
("cat epicsApps/bin/mv167/vxWorks.sym" in this case).
The shell is determined by the /etc/passwd (or NIS) entry of the user name
the IOC uses for the rsh (this user name is taken from the nvram).
In this case there is a "stty <something>" command in one of the init
scripts, where <something> is illegal (if you ask the shell).
> Error opening apis:epicsApps/bin/mv167/vxWorks.sym: status = 0x290010
This is just the message that getting the symbol table failed. I never saw
any explanation of the error codes in the doc. Four out of five Wind River
people don't know them, either.
Hope this helps,
Ralph
