RE: Ultrium 4 Tape Initialization

Not really. Ask him (the CFO) to put a dollar figure on the inability to
take customer orders, ship products, process payroll, etc. He can easily
translate into real money the cost of being down for a day or two while you
try to get the system up and running.

That requires a CFO with knowledge of technical operations. Is that common?

Perhaps your CFO could impress upon the SA the true cost of downtime
caused
by a faulty backup plan.

Visits from the guy who signs the checks tend to open eyes and ears.

The SA calls the shots. He spouts off about how important a backup is,
but
then decides he knows enough. He played with the idea of using BRMS. Not
used here. Probably won't be. The concept of unique media identification
may have been too "involved".

Lucky for us that the i is a very rugged system.

I still have a cringing sensation from an experience I had 23 years ago
with
a Xenix system. Disk controller got off frequency. Arrived at work to
find
a REALLY messed up computer. But, I had a full backup from the previous
day.

They didn't even care when you showed them the PRTERRLOG? Wow!
Try ordering a tape library system where the tapes HAVE to be barcoded
AND

have different volume id's. Push for BRMS or some similar product.

Really annoys me that procedure where I work is to initialize the tape
every night. Old habits die painfully hard. I have suggested that the
expiration date be changed from *PERM to a value more in line with the
tape rotation. That date could be generated from a CL program.

My biggest issue with continual tape initialization, beyond excessive
wear

and tear (which is a big issue), is that the wrong tape could be pulled
and the data destroyed.

I have also complained that tapes should have unique volume numbers, not

stupid things like DAILY. But, nobody seems to care. I even showed
them
PRTERRLOG output. And people wonder why things fail sometimes.

I worked in a bank thirty years ago that used 9 track tape. Only time
tapes were initialized was when the BOT marker was replaced.

But on a nightly

doing
this for decades.

But why, on a nightly basis, do so many of you run INZTAP anyway? Just

start the save at sequence 1 and let the save overwrite the previous
data. By constantly running INZTAP you:
a) wear out the start of the tape :)
and
b) mess up the read/write error statistics for the
tape.

Sure, initialise and clear a tape prior to disposing of it but
otherwise a tape should be initialised once and just reused.
