Hi:
Sessions and processes seem to be sinlge threading using a single drive
in a 4 drive library.
the dev is set to mountlimit=drive.
anyone know what else might cause this bottleneck?

As shown below, library with 4 drives only shows a mount waiting on a
volume when another is dismounting.

tsm: BACKUP>q mount
ANR8379I Mount point in device class 3494BTAPE is waiting for the
volume mount
to complete, status: WAITING FOR VOLUME.
ANR8331I 3590 volume 001038 is mounted R/W in drive 3590RMT4
(/dev/rmt4),
status: DISMOUNTING.
ANR8334I         2 matches found.
