Re: iSCSI: Naming and Discovery Draft...

[julian_satran@il.ibm.com]

Strange English.  In computerese committed is associated usually with:

- written successfully to stable media (like in committed to disk)
- transaction unit completed (transaction commit)

Even in informal English it is used as a negation only in statements like
"sorry, I had other (previous) commitments".  When left alone it has
"positive connotation" (like I am committed to do it).

You fellows don't make learning American an easy exercise for us poor
non-native speakers  -:)

On a more serious tone:

with controlers and devices busy is usually meant to convey 2 things:

- I am busy for a short interval
- I will tell you when I get free

If you don't intend to tell when you become free don't use busy.

You can use occupied (like in "lavatories occupied" - I am in an airplane
now -:))
It conveys exactly what you want.

Don't take me too serious - I am not good at naming but don't over-commit
committed.

Sounds like we are left with "Target Committed", which
Renato's new description seems to fit.

Any other ideas, or does that seem to work?
