Subject:   tape: can't set blocksize on Wangtek
Message-ID:  <7pk3r1$89o$1@bigeye.rhein-neckar.de>

4.0-CURRENT from a few days ago, QIC-1000 tape drive:
sa0: <WANGTEK 51000  SCSI RVM7 5F5> Removable Sequential Access SCSI-CCS device

Inserting a QIC-150 tape, and

$ mt blocksize 512
(sa0:ncr0:0:6:0): MODE SELECT(06). CDB: 15 0 0 0 c 0
(sa0:ncr0:0:6:0): ILLEGAL REQUEST csi:10,8,0,0

I've also had similar problems in other contexts, both with
SA_QUIRK_FIXED and SA_QUIRK_VARIABLE: "unable to set fixed blocksize to
1024", "unable to set variable blocksize". It seems the drive refuses
any command to change the blocksize from the hardcoded quirk entry in
scsi_sa.c.
