Upgrading 3590 Tape Drives???

2003-08-11 Thread Farren Minns
Hello all TSMers

Present setup as follows :-

TSM 4.2.2.12 running on Solaris 2.7, attached to one IBM 3494 Tape Library.
The library contains two 3590 B1A drives.

We are soon going to be upgrading our 3590 B1A drives to the H1A models so
that we can squeeze loads more on the tapes and free up slots in our
soon-to-be-filled library.

Now, as far as I am aware, this is a relatively simple operation. Am I
right in thinking that all that needs to be done after the drives have been
upgraded is to mark all tapes that are presently in the on-site Tapepool
(in the library) as read only. After this, only scratch tapes will be used
and I will be free to start running some movedata commands to start
consolidating tapes (using the new higher compression).

Am I right in thinking that the tape drives will automatically use the
highest compression available to the unless told otherwise?

Am I missing something here as it sounds all too simple?

And advice is very much appreciated.

Many thanks

Is anyone monitoring the drive internal logs or looking at them.  It sounds
like the drive pressure is out of alignment in all the drives.  This could
be because the CE you have has no idea what they are doing.

We have all four drives chewing up tapes on  regular intervals. To make a
rough estimate I would say that this happens  once or sometimes twice  a
month and all drives are effected in the same way. I have no idea if this is
the normal wear  due to lots of mounts. We always check out the tape which
caused the problem and in most cases we have a technician change parts of
the drive or even the whole drive. The age of our tapes is different. We
exchanged a lot of them to new ones, but also still  have  tapes which are
3, maybe 4 years old.

Just to make it clear: the drives do not fail at the same time, but one
after another in a certain period. Today it can be rmt1 which has a
problem, next week maybe rmt2, another three weeks later rmt0 and so on

I'll 2nd that on the cleaner blocks.  We had many problems with media
errors until we *made* the CE remove the blocks.  He shook his head and
said "Alright, it's your system"..Media errors just about vanished.

In 6 years of 3494 with 3490e and 3590 drives, I have only had 5 that were
destoryed by the drives.   Now if you want to count the number tapes
destroyed by operatorswell, that's a different story!

If tapes are being eaten, I'd say it is probably poorly adjusted pressures

In 7 years across 7 ATL's with 7 year old tapes (for the most part) we are

You can have one drive going wrong. I can even imagine two can have
problems simultaneously. But if all four together have a problem it is
hard to believe. Did your IBM CE verified the robot. Ask for same problem
re-open instead of open as new problem. As Wanda said shout, demand,
escalate the problem. You've paid a pile of money for those drives they
MUST work, period. Upgrade may help and may not, who will have to explain
why you spent another pile of money for upgrade.

Martina,
  I'm surprised to hear you are having 'lots' of hardware problems with
3590 drives. Do you have a maintenance agreement and have you called
support when you are experiencing problems?  You should!
  We have a 3494 library with 6 3590-E1A drives in it. These drives are
work-horses. We have had two service calls this year. But, you must
remember we are backing up 2700+ nodes, are using 700+ extended length
cartridges and keep those drives moving data around the clock.
  As for performance, I have seen transfer rates of 70GB an hour. This
is on tape to tape copies of storage pools (You won't see that when
migrating disk to tape.).
  The bottom line is that the 3590 is industrial strength! But, I must
admit having no experience with the B drive.

The different between the drives is the B1A are 128 track, the E1A are 256
track and the H1A are 384 track drives.
You gain one third capacity for every increment you go up on your drives.

We current have a total of 30 E1A tape drives between the open systems
backup and the MVS systems native drives.
Average at the most maybe two calls per year on the same drive different
problems never the same.
We still have a high percentage use per day.

Hi,

We are working with a 3494 IBM silo with 4  drives - 3590 type B -  which
is connected to a RS/6000. As we are having lots of  hardware problems
with
these drives we think about changing them to 3590 drives type E.
Does anyone have experience with this type of tape drive ? I`m mainly
interested in a kind of comparison concerning performance and availibility
between the both types B -> E.

Thanks a lot

Dave,

I recently upgraded one of my clients from B's (SCSI) to H's (fibre) on an
AIX server.  We had some initial quirks, which seem to have been cured by
firmware.

Aside from that, we have seen an increase in the number of tapes getting
flagged readonly, which we expected due to the increased track density.

We have NOT seen any significant increase in speed, despite the marketing
claims.  We are, however, getting 3X as much data on a tape.

Re: 3590 Tape Drives

2002-11-19 Thread Prather, Wanda
We have 2 3494's with a total of 15 3590 drives attached to a mainframe, and
to Windows TSM.
We started with the B drives, upgraded them 18 mo ago to E drives.

Performance/availability of both drive models has been superb.  (We upgraded
for capacity, not availability issues.)

We occasionally see a tape dismount failure.  We have also had the "brushes"
wear out and have to be replaced. But when the CE fixes that sort of
thing, it stays fixed.  We definitely see less than 1 service call per year,
per drive, not repetitive problems.

The 3590 drives (B or E, I have no experience with H yet), along with the
STK 9840's, are the most robust drives on the market today (well, except
maybe those things in the "black boxes" on airplanes)  You should NOT be
having ANY repetitive hardware problems with them.

Most repetitive problems with this type of drive turn out to be backlevel
microcode, or bad media.

You should manage your media aggressively - make sure you keep a list of
which tape is in the drive when you have a problem, and if the same tape
shows up twice remove it from the 3494, at least until this problem is
resolved.

Yell at your CE, a lot.  Make him/her check the microcode levels.
Call the district CE manager and demand an explanation of why you are
continuing to have problems with IBM's premier enterprise class drive that
works great for other sites.  Make them call in the district technical
specialist.  Keep him/her on site until the problems go away.  Demand that
if they can't fix the drives, they replace the whole thing (that usually
gets their attention).

Sometimes, you have to yell if you aren't getting sufficient service.  And
sometimes, your CE just needs some help getting the problem escalated in his
management chain.  BUT, these drives should work.  You shouldn't have to
upgrade to get rid of hardware problems.

Had IBM come in and upgrade the microcode and the software levels on

  I'm surprised to hear you are having 'lots' of hardware problems with

drives. Do you have a maintenance agreement and have you called support
when
you are experiencing problems?  You should!
  We have a 3494 library with 6 3590-E1A drives in it. These drives are
work-horses. We have had two service calls this year. But, you must
remember
we are backing up 2700+ nodes, are using 700+ extended length cartridges
and
keep those drives moving data around the clock.
  As for performance, I have seen transfer rates of 70GB an hour. This is
on
tape to tape copies of storage pools (You won't see that when migrating

to tape.).
  The bottom line is that the 3590 is industrial strength! But, I must
admit
having no experience with the B drive.

Subject: 3590 Tape Drives


Hi,

We are working with a 3494 IBM silo with 4  drives - 3590 type B -  which is
connected to a RS/6000. As we are having lots of  hardware problems with
these drives we think about changing them to 3590 drives type E. Does anyone
have experience with this type of tape drive ? I`m mainly interested in a
kind of comparison concerning performance and availibility between the both
types B -> E.

Thanks a lot

Re: 3590 Tape Drives

The H1A drive is a 50% capacity increase over the E1A drive.

DriveNative capacity   Extended Length Cartridge Capacity
3590-B1A 10GB  20GB
3590-E1A 20GB  40GB
3590-H1A 30GB  60GB

These numbers are without hardware compression. I believe throughput of
15MB/SEC applies to all 3590 drives thus far.

Glad to hear someone is having good luck with the E1A drives.  This past
year I have had IBM out at LEAST 2 dozen times working on my drives!!!  The
worst part is they bring used parts.  They have had to go back & pickup the
same part again because the replacement parts have been BAD a bunch of
times!!
I have seen posts about H1A drives.  What is the difference?

  I'm surprised to hear you are having 'lots' of hardware problems with 3590
drives. Do you have a maintenance agreement and have you called support when
you are experiencing problems?  You should!
  We have a 3494 library with 6 3590-E1A drives in it. These drives are
work-horses. We have had two service calls this year. But, you must remember
we are backing up 2700+ nodes, are using 700+ extended length cartridges and
keep those drives moving data around the clock.
  As for performance, I have seen transfer rates of 70GB an hour. This is on
tape to tape copies of storage pools (You won't see that when migrating disk
to tape.).
  The bottom line is that the 3590 is industrial strength! But, I must admit
having no experience with the B drive.

There are at least three ways to do phased migration to new media for
primary storage pools. You can make the storage pool containing the
new media the next pool for the old storage pool. You can then lower
migration thresholds when you want migration to start and raise the
thresholds when you want migration to stop. You can run 'move data'
commands with the 'stgpool' option to move the contents of individual
volumes in the old storage pool into the new storage pool. You can
define the new storage pool as the reclamation pool for the old storage
pool and control data movement by adjusting the reclaim percentage for
the old storage pool.

There is no explicit mechanism for moving data from one copy pool to
another. You will have to populate the new copy pool by running 'backup
stgpool' commands. The processes created by these commands can be
cancelled if need be to break the copying process into managable
chunks. Once the new copy pool is synchronized with the relevant
primary pools you can delete the volumes in the old copy storage
pool.

TSM will fill an onsite 3590 tape completely. TSM will fill an offsite
3590 tape until it reaches the end of the tape or until the status of
the tape is updated to mark the tape as unavailable for mounting.



New 3590 tape drives

2002-11-07 Thread Jim Kirkman
We're (finally!) looking at purchasing some native 3590 drives for our
3494 library, which we share between TSM and HSM on OS\390. Currently
we're using 3490 and VTS for our copypools. A couple of questions arise.

1) Will TSM allow us to slowly migrate our tape storage pools to the new

native 3590 tapes or is this a situation where we would have to
move/migrate the data from 3490 (physical or logical) to the 3590 tapes
all at one time?

2) If we make our TSM backup storage pool 3490 (logical) and the
disaster recovery pool 3590 native tapes, would TSM make full
utilization of the 3590 capacity?  Or, would it be a 1-to-1 tape usage?

Any experiences to share, or other concerns to address?

Re: Question about 3590 tape drives

2002-04-03 Thread Christo Heuer

Hi Gerhard,

stop/start processing of the tape drive - the disk pool does not
stream the data fast enough to cause a continues flow of data - hence
when there has been a stop in the flow of data there needs to be some
kind of re-positioning - to continue writing where the last bit of
data was written.
Normal behavior.

Cheers
Christo

Hello,
I observed some strange behaviour of a 3590-E1A tape drive. During a
migrate operation from a disk pool to a sequential pool I watched the
operator panel. There I could see that the device after a write operation
did a locate followed by a read and then resumed writing. I observed this
behaviour several times. Is there an explanation for this?
I run TSM 4.1.2 on AIX 4.3.3

Re: Question about 3590 tape drives

2002-04-02 Thread Seay, Paul

When the tape stops during writing it must backup and get the tape moving
again before it can write to it.  This is normal.  I have seen this also on
NetBackup and TSM.  It is an internal hardware thing.  This is very fast on
a 3590 and very slow on other tape offerings.

Hello Gerhard

I.m not sure, but one could guess that the drive was doing some
[successful] error
recovery operation or perhaps some internal drive calibration ?

Re: 3590 tape drives

The drive can physically tell what type of cartridge is in it.  The
Extended Length upgrade adds the ability to read/write the longer tapes,
but doesn't take away any other capabilities.

If you look at the label end of a 3590 tape, there are two plastic inserts
below the label (if the gear drive side is down).  There are notches taken
out of these inserts which allow the drive to tell what type of tape it is.
CE cartridges, Cleaning tapes, 3590, 3590XL, all have different codes with
the notches.

we have in our tape-library (IBM 3494) Magstar 3590 Modell E drives (E1A).
Because they were bought one year ago, they don' t have the facility to
read/write the extended-length-cartridges, so we use the normal cartridges
with 20 GB uncompressed.

Now we plan to upgrade those drives (IBM-upgrade-Kit) so that they can
