True enough, James can handle it, but the "get maintenance on production
systems" is a standard disclaimer that's required to keep out of the eyes of
a courtroom.......

Well, buying an extra drive at $400 buys how many months worth of
maintenance?
I might ensure that the firmware is up to date on both drives so that the
spare doesn't get too far behind over time. Besides that gives you
assurance that it will work when needed. A little drive testing so to
speak.
As plug and play as these are (no torch required) I'm betting James could
handle this.

Rob:

Given the 10% - 15% difference in acquisition costs I would always go with
Fibre (8GB to keep the cost down a bit and that still supports NPIV)

Used is fine, the only thing to consider is the warranty vs. maintenance
on
a tape device is significant. Personally I self-maintain tape libraries
and
drives since they usually need replacements when they fail, so I keep a
spare on hand. Then again on a mission critical system with production
depending on the tape, get maintenance.

Good thinking Jim.
Unload/reloads between systems with incompatible tape drives is always a
challenge. At best you can hope for is some friendly with every tape
drive
known to man attached to their system to dup tapes for you. You can bet
that will be a serious delay in your upgrade. That and you have to time
it
for when they aren't busy.

Is the ability to do SAS attachment pretty much a given with systems
still?
If you had a choice between fiber tape and SAS tape which would you
choose?
Me, fiber. But we have the switch and all which really helps. Not that
it
should make a big diff to a single lpar, single drive in the library shop.
And James might already have the SAS capability.
Even if he later had to dump SAS there are used fiber LTO5's to be had so
he
wouldn't obsolete his tapes.

There have been a lot of announcements about IBM pulling LTO5 drives from
the market but James doesn't strike me as someone reluctant to purchase on
the used market.

Since that system is slated for end of hardware support in early 2019, and
cannot be upgraded to OS V7.3, I would want to find a tape drive that
would
be compatible with both this box and my shiny new Power 9 box I hope to
get
next year (Santa are you listening?) . Otherwise you are going to invoke
the spend money command for a tape drive now, and again for a tape drive
in
the next few months. Now, does such a drive exist? I don't know, but that
would be high on my criteria.

subject: Backup media

With a worn out DAT160 backup tape on our production box, I went looking
for replacement media.

And I discovered that DAT160 is considered an obsolete format, with
availability limited to stock on hand.

Given that we have a rack-mountable E4A, with a DAT160 drive for backup,
can anybody suggest any long-term options?
