to readonly or can I let TSM do it for me.  IBM says that the new drives will
not write over a non-scratch tape in the old format.  When TSM calls for an
output tape and the drive detects the old format will it genrate an error that
causes TSM to mark the tape readonly and then mount a scratch tape?  Or should
I set the B tapes to readonly before bringing TSM up with the new drives?

If I remember correctly, the TSM-Sever internally records for each tape,
whether ist has been written by a B-type or E-type drive, and refuses to
_continue_ to write a B-type tape on an E-type drive. You thus only need
to set the FILLING tapes to READONLY, no need to set them all to READONLY
or to define a new storage pool, as someone else mentioned.

It is important, that the TSM server recognizes the new drive types. This
is done by deleting and redefining the drives.
