Re: FICON-Attached 3590 Tape Drives Not Detected

[Tom Duerbusch]

When I use 3590 tapes here, this is what I do:

vary on 5b1 (vary it off first on the other lpar)
attach 5b1 LINUX72

>From Linux:

lstape
chccwdev -e 0.0.05b1  (set drive online)
lstape
mtst -f /dev/ntibm0 rewind
mtst -f /dev/ntibm0 fsf 1
mtst -f /dev/ntibm0 compression 1

However, you have to install the mtst tar file (part of the IBM code) to use 
the mtst command.
Without mtst, I don't believe that you can turn on/off compression on your 
drives.

Hello,

I have RHEL 6 Linux running as a guest under z/VM 6.1 on our z10 BC. It has the
following 3590-H tape drives assigned in the z/VM directory:

DEDICATE 1500 1500 MULTIUSER
DEDICATE 1501 1501 MULTIUSER
DEDICATE 1502 1502 MULTIUSER
DEDICATE 1503 1503 MULTIUSER

A query command shows the drives are attached to the Linux guest:

q 1500-1503
TAPE 1500 ATTACHED TO ZLINUX1  1500 R/W  NOASSIGN MULTIUSER
TAPE 1501 ATTACHED TO ZLINUX1  1501 R/W  NOASSIGN MULTIUSER
TAPE 1502 ATTACHED TO ZLINUX1  1502 R/W  NOASSIGN MULTIUSER
TAPE 1503 ATTACHED TO ZLINUX1  1503 R/W  NOASSIGN MULTIUSER

However, the lstape command shows no drives:

FICON/ESCON tapes (found 0):
TapeNo  BusID  CuType/Model DevType/Model   BlkSize State   Op  MedState

SCSI tape devices (found 0):
Generic DeviceTarget   Vendor   ModelType State

I found the driver here:

/lib/modules/2.6.32-131.17.1.el6.s390x/kernel/drivers/s390/char/tape_3590.ko

What am I missing? How can I get Linux to recognize these tape drives?

The module is most definitely NOT loaded.


Modprobe loads the module without problems. lsmod then shows tape_3590, tape and
tape_class as new modules:

Module  Size  Used by
tape_3590  31467  0
tape   61843  1 tape_3590
tape_class  2981  1 tape

But the drives themselves are still not detected. I think I need to hit the
books on this driver to see if there's anything special I should be doing.
Thanks for your help...

The 'MedState' column in the 'lstape' output will contain OFFLINE for any
offline device(s). For example:

lstape
FICON/ESCON tapes (found 1):

FICON-Attached 3590 Tape Drives Not Detected

[Edward Jaffe]

Hello,

I have RHEL 6 Linux running as a guest under z/VM 6.1 on our z10 BC. It has the
following 3590-H tape drives assigned in the z/VM directory:

DEDICATE 1500 1500 MULTIUSER
DEDICATE 1501 1501 MULTIUSER
DEDICATE 1502 1502 MULTIUSER
DEDICATE 1503 1503 MULTIUSER

A query command shows the drives are attached to the Linux guest:

q 1500-1503
TAPE 1500 ATTACHED TO ZLINUX1  1500 R/W  NOASSIGN MULTIUSER
TAPE 1501 ATTACHED TO ZLINUX1  1501 R/W  NOASSIGN MULTIUSER
TAPE 1502 ATTACHED TO ZLINUX1  1502 R/W  NOASSIGN MULTIUSER
TAPE 1503 ATTACHED TO ZLINUX1  1503 R/W  NOASSIGN MULTIUSER

However, the lstape command shows no drives:

FICON/ESCON tapes (found 0):
TapeNo  BusID  CuType/Model DevType/Model   BlkSize State   Op  MedState

SCSI tape devices (found 0):
Generic DeviceTarget   Vendor   ModelType State

I found the driver here:

/lib/modules/2.6.32-131.17.1.el6.s390x/kernel/drivers/s390/char/tape_3590.ko

What am I missing? How can I get Linux to recognize these tape drives?
