Hi David and Burak!
My I/O error problems are solved. The drives were not the problem. The
library tried to move a tape from a drive to a storage slot. It failed to do
so (due to a incorrect alignment of the gripper) and thus it re-inserted the
tape into the drive. This renders the drive unavailable to TSM.
I realigned the gripper an everything works fine now.
Thanks again!
Kindest regards,

Eric,
I have a 3575-L32. They key point in your original message is
that a drive was replaced. Power off library and carefully examine
all connections at library on the SCSI cable path to that drive.
Not just the one connection that was involved, maybe connection
on other end of cable that developed problem when "moved".
We have had two occaisions where there was one recessed pin
in SCSI connector and it can give strange results - it won't work!
Might check SCSI on new drive also.

Hi Burak!
No luck...
We have done the following actions:
1) I varied the drives offline in TSM
2) We removed the drives and library from SMIT (keep definition=no)
3) We installed Atape 7.1.5.0
4) We ran a rmdev -l fcs0 -R to refresh the devices AIX sees at the
fiber
channel end.
5) We ran CFGMGR so the drives are redetected.
6) Varied the drives online in TSM
So far so good, but as soon as I started a backup stgpool to the
library I
again receive the same errors for the same two drives...
I hope you, or someone else, has any more suggestions.
Kindest regards,

Subject: random I/O errors since
repairs
Hi *SM-ers!
We have a 3575-L32 library. About a week ago the library was
unavailable due
to a broken drive (drive 1 which is also the library control path).
The
power board was replaced and everything looked fine afterwards.
Since then, every now and then drives go offline after the following
error:
ANR8300E I/O error on library 3575LIB-R1 (OP=00006C03, CC=207, KEY=05,
ASC=2C, ASCQ=00,
SENSE=70.00.05.00.00.00.00.0A.00.00.00.00.2C.00.00.00.00.00.,
Description=Device is not in a state capable of performing request).
Refer
to Appendix D in the 'Messages' manual for recommended action.
ANR8446I Manual intervention required for library 3575LIB-R1.
Unrecoverable drive failures on drive RMT5 (/dev/rmt5); drive is now
taken
offline.
I tried everything. Deleting the drives from AIX, purging the SAN Data
Gateway device database and rescan the SCSI interface, nothing seems
to
work.
I checked Appendix D for ASC=2C, ASCQ=00. The only line I can find is:
0x2C 0x00 Command sequence error.
I'm lost!!!!
Any help will be VERY much appreciated!
Kindest regards,
