Re: Label reading problems 3584 library

Include both lto1 and lto2 in the same tape pool showing the same
capacity. The lto1's will still write at their capacity. In
transitioning to lto2 just manually mark the lto1's read only and later
destroyed. This will allow you to eventually be all lto2's if that is
what you wish to transition to.

Hi David,

In a perfect world I would been able to give the volume range to use.
In
this world some one ordered the LTO2 tapes with labels in the same
range
as our LTO1 tapes. Because we asked for 400 tapes, they ordered 200,
so
we are forced to use our LTO1 tapes in this LTO2 partition.

Quick fix, we use the L1/L2 to be out of harms way.

So, even if this wonder boy will be the one ordering the LTO3 tapes,
it
will not hurt us....

Regards,

Karel

We only use the first 6 chars.  Have no problem knowing what type of
tape it is in TSM because...  I specifically order tapes with certain
prefixes.

Class            Volser start
LTO1              A00000
LTO2              B00000
LTO3              C00000

You can use others for what is most useable to you.

Oh someone may ask, what about WORM LTO3 tapes now?

Volser start WC0000, "W" for WORM!

Just a little idea!

Hi Richard,

Thanx!

For some reason, I'm still rather new to AIX, Smit(ty) didn't let me
change this option. Now it is set to 8.

The reason we like to see the L1/L2/L3 part of the label.

Regards,

Karel

Hi, Karel -

The IBM TotalStorage Tape Device Drivers: Programming Reference manual
defines the low-level ingredients of tape processing, and there the
volser storage field can accommodate 8 chars.

In looking at the Atape.fixlist file, I note level entry:
  9.2.9.0   Add SMIT option to set 3584 TSM barcode length for
Ultrium 1/2 media
You might look into your AIX SMIT and see if yours presents that
capability.

Note, however, that it is best to use six characters, as per the TSM
Implemenation Guide redbook:
"Although IBM Tivoli Storage Manager allows you to use a volume
  identification longer than six characters, we strongly recommend
that
you use
  up to six alphanumeric characters for the label (also known as
VOLSER
or
  Volume ID). This should be compatible with other ANSI styled label
systems.".
(The first 6 chars of the label are the volser/volid, the last 2 are
the
media identifier, per "IBM LTO Ultrium Cartridge Label Specification",
IBM site item S7000429.)
