    This problem will be fixed in V2.9.  With the fix in place,
    CONTLOADOPT=0 becomes the best option for unattended backups (using
    AUTOSEL=1) to magazine loaders and libraries (TL8xx, Storagetek silos, 
    etc.).

    Thanks for bringing the problem to our attention.

2168.9SLS to init blank tapes ?TRUCKS::WIMBLEDON_PWed Feb 26 1997 10:016
    Related scenario, if UNATTENDED_BACKUP = 1, CONTLOADOPT= 2 and I 
    have a blank tape (previously UNINITILIASED) then I would expect the tape 
    to be automatically inited by SLS, ie the OPCOM message to be satisfied 
    without needing operator reply. 
    
    Is my assumption correct for 2.8 and does it change in 2.9 ? 
2168.10SLS V2.9 doesn't change behaviour for CONTLOADOPT=2BACHUS::RENTYThu Feb 27 1997 04:3830
    My experience was that SLS will WAIT for an operator reply, even if
    UNATTENDED_BACKUP=1 (see my test in .7).
    
    On the one hand, with UNATTENDED_BACKUP=1 and CONTLOADOPT=2, I would also 
    have expected SLS to initialize these blank volumes, but on the other hand
    it would be a dangeuous idea that SLS starts initializing volume every 
    time it detects a volume label mismatch...   So I think the behaviour is 
    not really that wrong.
    
    For V2.9, only the behaviour for  CONTLOADOPT=0 has changed, so that
    SLS will continue with another volume.
    
    This is the answer from Marty on my CLD (IPMT BRO100919 , CFS.48536) :

2168.11unmatched - operator, blank init ?TRUCKS::WIMBLEDON_PTue Mar 04 1997 06:244
    
    I can see with unmatched labels you would not want to automatically
    relabel even in unattended mode,  I think there is a case for initing
    blank tapes.
