48.0. "Failover" by SUPER::MATTHEWS () Mon Feb 04 1985 23:25

I've done a little research on the word "failover." (To a language purist,
"failover" may sound like doublespeak from your worst nightmares. It's commonly
used when talking about VAXclusters, and I present an example for the
uninitiated: when a disk is dual-ported between two HSC50 controllers, and one
controller fails, the other controller takes over. That's failover.) This word
demonstrates some of the things that can happen when jargon suddenly and
ungracefully enters the English language. 

What prompted this research was my writing a sentence using "failover"
(actually, "fail over") as a verb. (The sentence was something like: "The disks
fail over to the other HSC50.") The editors here in Software Course Development
ruled that "failover" is a noun and only a noun (which forces me to write
something clumsier, like "Disk failover to the other HSC50 takes place"). 

Their viewpoint is understandable. The DIGITAL Software Publications Style
Guide defines acceptable and unacceptable jargon. Inventing a word is
acceptable jargon, if there's no existing word that works. Turning a noun
into a verb is unacceptable jargon (our old friends "interface" and "access"
appear as examples in the manual). However, I have no evidence that the use of
"failover" as a noun predates its use as a verb, so I would argue that the rule
doesn't hold in this case. 

Existing publications serve as precedent for using "failover" in all kinds of
ways, and informal writing and conversations even more so. Here are some
examples, with usage marked as noun [n.], transitive verb [v.t.], or
intransitive verb [v.i.]: 

"For each dual-ported HSC disk, you can control failover [n.] to a specific
port using the port select buttons on the front of each drive. By pressing
either port select button (A or B) on a particular drive, you can cause the
device to failover [v.i.] to the specified port... The port select buttons also
enable you to failover [v.t.] all the disks to an alternate port manually when
you anticipate the shutdown of one of the HSC50s." -- Guide to VAXclusters,
page 4-7. 

"If one of the HSC50s fails, the VMS operating system will failover [v.i.] to
the second HSC50, transparently to the user... On a failover [n], the active
path may change to a different controller." -- VAXcluster Software Technical
Summary, page 32.

"If an HSC-50 fails, it may take up to about 30 seconds for the disks to
failover [v.i.] to a second HSC-50." -- Dave Thiel, response 85.3 in the
CLUSTER notesfile.

"The automatic login failover [n.] switches a user's terminal to an alternate
node in the cluster if the user's current node fails." -- VAXcluster Software
Technical Summary, page 33.                         

In addition to HSC50 and LAT failover, the word can also be used for a cluster
state transition in which a node is removed from a cluster. I have also heard
it used to describe what some of our customers wish their processes would do
when a cluster node goes down. (There may be still more situations to which the
word "failover" applies, and I don't know whether the word exists outside DEC,
or even outside VAXcluster-land.) 

According to examples in print, to get failover to occur someone may "perform
failover," "cause failover," "control failover," or "accomplish failover," or
the disks themselves may "perform failover." 

As to the original problem, I am still arguing to be allowed to use "failover"
as a verb, but I think it ought to be intransitive ("cause the disks to
failover," rather than "failover the disks"). 

Of course, if we allow "failover" to be a verb, we have to be able to conjugate
it. I can write "the disks failover", but do I write "the disk failovers" or
"the disk failsover"? I have NEVER seen it written as "fail over," but it
definitely should be. (Now the verb becomes simply "fail," and no one would
argue against its being a verb, right?) 

Perhaps this little word will settle down and become well-behaved someday, and
perhaps not. I for one will enjoy watching what happens.

As far as the verb that may or may not be, if it becomes a verb, the part that
is prepositional should seperate from the verb it self, 'to fail over'.  That
way it is explicit that the conjugation would then follow the conjugation of
the verb 'to fail.'  You have never seen it seperated?  Have you seen things
that others have written that are not proper, 'your' for 'you're,' et cetera?

What used to confuse me was how to handle the verb blow-dry, as in hair.  Had I
blow-dried my hair, or had I blown-dry my hair or had I blown-dried my hair.
Which leads to: 'blew-dry,' 'blew-dried' and 'blow-dried.'

Failover?  Geez, the word gives me an unspeakable pain.  Who 
outside of Digital is even going to know what the word means?  
There are other ways to get the same point across . . . .

Should the noun form be 'over-failure'?

If we (Digital) are going to prescribe rules about how to use the words
we invent, maybe we should copyright the words.

Failover (n.) (c) Digital Equipment Corporation, Maynard, Massachusetts,
what disks do after they fail.  They failover again.  Slightly redundant.

"Over-failure" sounds like a nasty destiny for an "over-achiever."

re .2:

	Geez, the word gives me an unspeakable pain.

But apparently not untypable pain... :-)

	Who outside of Digital is even going to know what the word means?

An awful lot of people do/will. The first time I heard the word was as a
software specialist. I was asked, "When are you guys going to have failover?" I
think you're uncomfortable with the word because you are unfamiliar with it.

	There are other ways to get the same point across . . . .

Name one. More to the point, name one that isn't a circumlocution. I like the
word. It has a certain euphony and rolls off the tongue easily. What "failover"
needs is a rigorous definition. Then we can make noise when it is used
improperly. Let me give a first draft definition:

Fail over, vi. [FAIL, v. + OVER, prep] to transfer control, function, or
responsibility [the disks fail over] -- vt. to cause a redundant system to
assume the function of or responsibility for [fail over the disks]

Failover, n. The process of either of the above. [failover occurs when X
happens]

I don't see the problem with using "fail over" as a transitive verb. If I can
crash a computer, then I should be able to fail over a computer.

I'm not entirely pleased with this definition; I think that it is both too
vague and too specific. Comments, anyone?

Re .1:  << flame >>

Look, you guys.  The name of this Notes file -- look above -- is 
supposed to be "JOY of lex".  .1 above is anything but a joy.  (Yes, I 
know this should go in as a reply to some other note, but it would 
probably be SEVERAL notes, and I don't have the energy or patience to 
look for them -- across the Atlantic, as you might say.)

Here it is:

>As far as the verb that may or may not be, if it becomes a verb, the part that
>is prepositional should seperate from the verb it self, 'to fail over'.  That
>way it is explicit that the conjugation would then follow the conjugation of

>Which leads to: 'blew-dry,' 'blew-dried' and 'blow-dried.'

(a) "As far as" what?  Is there perhaps something missed out -- 
    "... is concerned", possibly?

(b) "SepErate" yet again???!!!

(c) "Separate" what?  It is a TRANSITIVE verb.  Or was it "BE separate"?

(d) "It self"?

(e) "Had I ..." without quotes AND without the tiniest little question 
    mark?

(f) A sentence beginning with "Which"?  (None of these points are 
    sentences either, I must admit.  But this is a flame.)

Ah well.  Once a pedant, always a pedant, I suppose.

This quote, from writer Gilbert Highet, appears in the American Heritage
Dictionary:

        I have great admiration for the American genius for creating
        short vivid words (often dissyllabic) to express complex ideas,
        for example, a collision between a vehicle and another object
        which is not direct but lateral or oblique, "sideswipe." 

"Failover."
48.8NY1MM::SWEENEYThu Feb 21 1985 21:3710
Try thinking of "succeedunder" as the opposite of "failover".

We've got "holdover" as in "His ideas are a holdover from the days when you
could sell computers without marketing them."

We've got Passover.  We've got "hangover" (and "overhang").

Hey!  This is fun! What other "-over" words are there?

Pat Sweeney
48.9NUHAVN::CANTORFri Feb 22 1985 02:1115
East Overshoe.  I believe it's somewhere near the source of Schytz Creek (where
you can be up without a paddle), and just south of Frostbite Falls. 

Oops.  Sorry, Pat.  You asked for "-over" words and I gave you an "over-" word.

Pushover.  
Overring.  (Something a cashier does, and also the wrongly uprung amount.)
Overbearing.
Overcoat.
Oversee, -r, -ing
Overseas.
Left-over.

Turnover as in the apple variety.

Pat Sweeney
48.11SUPER::MATTHEWSFri Feb 22 1985 10:1712
"Turnover," which is not the same as "overturn."
"Takeover," which is not the same as "overtake."

Since writing .0 I've read some of the non-DEC literature on fault-tolerant
computing. Some writers use "takeover" and "switchover" like we use "failover,"
and I bet I could find more words for the same thing if I kept reading. There
are computer scientists who spend their time pinning down definitions of words,
so maybe someday there will be industry-wide agreement on this one. 

(I like "succeedunder," and am looking for a context in which to use it...)

I believe the word you're looking for is one of those listed in .12 --

	REC-OVER

(As distiguished from WRECK-OVER, that is, to wreck again.)

What the disk subsystem does after a failure is recover from the failure 
(with the help of the operating system software).
