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,

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,
