I bet you are correct Jeff.  Via the front panel, it says the control paths
are required for all drives and it won't let me change it.  I will work with
IBM tomorrow to find out why.

LTO Lib rary


I have 3 FC connections from my TSM server (AIX) and one from each (3) SDG
into my McData SAN Director (ED-5000).  All of those (6) connections are in
a zone by themselves.  It sounds to me that Jay's problem might be that the
control path to the 3584 library is going across each LTO drive instead of
just the first drive.  But Becky is right...  You should see each device on
each fibre channel adapter.

EXAMPLE:  In my situation (see original reply below) I see 19 devices (15
LTO drives, 3 LTO libraries, and one 8mm tape drive).  Since the 8mm drive
is direct-attached-SCSI, I should see only one.  Since I have 3 FCAs into
the SAN, I should see all the other devices three times (once for each FCA).
I really just have one library with five drives in it.

Jay, if you are seeing one library for each drive, I'd start looking at the
library for issues.  The 3584 library should use the first drive as the
control path between the library and the operating system.  This is fine as
long as that first drive doesn't have SCSI problems...  If THAT happens (or
if you lose the FCA that controls that first drive) you could lose the whole
library (like I did last week).

Am I understanding this correctly...?  You have ONE 2108 running FOUR drives
that live in ONE library... right...?  If so, and you see four libraries AND
four drives, your control path HAS to be going across each drive.

Jeff

P.S. - Are you in the 817 area code?

Zoning for both the San Data Gateways and the Switches will probably help
that.  If there are for example 4 drives on a san data gateway  and 2 paths
from the switch to the san data gateway then you will have 8 drives because
each path sees all 4 drives.  If you then have 2 fibre adapters going to the
switch then you will see 16 because each adapter sees everything on the
switch.  Make sense?

I had that problem when I had too many paths going to the SDG's.  I had two
FC Switches tiered together and both switches each had a path to two
separate SDG's.  I removed the link between the FC Switches and the problem
went away.

In that case, I was seeing 8 libraries and 8 drives.  Now I am down to 4
libraries and 4 drives.  It should be 1 library and 4 drives.

Jay,

Does your NT server see 4 or 16 drives...?

I don't know how much help this is, but I'm running a similar environment
here.  The only major difference is that my TSM server is an IBM RS/6000
(H80) running AIX 4.3.3...   Anyway, within AIX, I see 15 drives and 3
libraries (like this):

rmt15 Available 14-08-00-6,0 Differential SCSI 8mm Tape Drive
rmt0  Available 17-08-01-0,0 IBM 3580 Ultrium Tape Drive (FCP)
smc0  Available 17-08-01-0,1 IBM 3584 Library Medium Changer (FCP)
rmt1  Available 17-08-01-1,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt2  Available 17-08-01-2,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt3  Available 17-08-01-3,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt4  Available 17-08-01-4,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt5  Available 24-08-01-0,0 IBM 3580 Ultrium Tape Drive (FCP)
smc1  Available 24-08-01-0,1 IBM 3584 Library Medium Changer (FCP)
rmt6  Available 24-08-01-1,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt7  Available 24-08-01-2,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt8  Available 24-08-01-3,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt9  Available 24-08-01-4,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt10 Available 2D-08-01-0,0 IBM 3580 Ultrium Tape Drive (FCP)
smc2  Available 2D-08-01-0,1 IBM 3584 Library Medium Changer (FCP)
rmt11 Available 2D-08-01-1,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt12 Available 2D-08-01-2,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt13 Available 2D-08-01-3,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt14 Available 2D-08-01-4,0 IBM 3580 Ultrium Tape Drive (FCP)

That's not a problem though, because when I set up the 3584 in TSM, I set it
up to use "smc0" for the library and "rmt0, 1, 7, 8, & 14" for the
individual drives.  This way, fibre channel adapter 0 runs the first SAN
Data Gateway (IBM 2108 - R03) which controls the first two drives and the
library.  FCA 1 runs the next 2108 (and rmt7,8).  FCA 2 runs the last 2108
(and rmt14).   The only thing left is "rmt15" which is a direct-SCSI
attached 8mm Tape Drive that I use for "mksysb" in AIX.

Although my server that runs TSM is seeing multiple instances of the same
devices, it doesn't affect the way TSM works because of the way I define the
devices within TSM.  I don't know what the difference would be in NT, but
since it's all SCSI over FC I'd like to think that they would at least be
similar among all open systems platforms.

Thank you,

If you REALLY want to see something neat, stop and start the device driver.
Every time you do that, the SCSI ID increments to the next highest number
not used.  Our company installed a similar system for a client and
encountered this behavior as well as many other issues.  Seems that the
"SCSI drive code has not been written to fully function properly with the
dual fibre path configuration that we have between the SAN Fibre Switches
and the servers. They seem to believe that this dual FIBER path is causing
the drives to get multi-initiated."  Weather this has something to do with
multiple libraries showing up, I am not sure but, rest assured, it ain't
helping.  Hope this helps a little.....

Hello all.  I was wondering if anyone had this configuration?  I am running
TSM 4.1.1 on a Netfinity 6000R with NT4SP6a.  The server is connected to a
FC Fabric consisting of an IBM 2109-S16 FC Switch.  This then connects via
longwave fibre to a SDG 2108-G07.  Finally we get to attach the 4 tape
drives to the gateway.

My problem is this:  I have four tape drives and NT sees four libraries.  I
know its a problem with either the SDG or NT driver levels.  Here are some
specifics about firmware/driver levels

3584 Library NT Drivers: 1.1.7.6
3584 Firmware: 1200
Qlogic 2200 Firmware: 2.1.16
Qlogic 2200 NT Driver: 7.05.05 NT4 IP
Qlogic Bios: 1.61
SDG Firmware: 0341.31
FC Switch Firmware: 2.1.7

Please let me know if anyone can help me get my TSM server to see 1 library
with 4 drives.

Thanks much,
