Hi,

I had the same some weeks ago, one of the 4 3590 drives asks for cleaning
after every tape dismount.
After CE checked the drive, it seems improved a bit. Although not asking
for clean after every mount the frequency is still high (~clean per 3 to 10
mounts)

Here is the errpt:

IDENTIFIER TIMESTAMP  T C RESOURCE_NAME  DESCRIPTION
D1A1AE6F   0603092499 I H rmt3           TAPE SIM/MIM RECORD
E507DCF9   0603091899 I H rmt3           TAPE DRIVE NEEDS CLEANING
D1A1AE6F   0603045899 I H rmt3           TAPE SIM/MIM RECORD
E507DCF9   0603045599 I H rmt3           TAPE DRIVE NEEDS CLEANING


From lscfg -v, all 4 drives are at   Device Specific.(FW)........97BF

Thanks
