766.0. "failed disk" by DAIVC::TEGUH () Tue Mar 18 1997 21:35

    guys,
    
    My customers is using DECsafe and LSM environment with SW800 as a shared
    storage which is mirrored. I was confused how come error messages showed
    up and interrupted process on both machine everytime there was a failed
    disks on the SW800. And in the worst case when we tried to reboot the
    systems the systems got hung. We had to delete the failed disk from HSZ
    command unless the systems never came up. What I don't understant if we
    have to be present all the time, what the use of mirroring and DECsafe
    as the solution. 
    My question is :  What can we do on the LSM configuration to avoid this
    problem, so the systems would be up with mirroring disks without
    disrupting any process when the systems booting  up or running ?
    
    I need the responds ASAP.
    
    thanks in advance.

    Hi,
    
    I think the problem is in the HSZ which is entering a retry loop and
    thus is delaying the I/O error message. A lot of notes in the ASE
    notefile are also complaining that "LSM" is "hanging" the system and
    every time an HSZ is playing in that config...
    
    So, I suggest you ask the HSZ conference, but maybe you should rephrase
    your note like: " What event(s) can cause the HSZ to delay the I/O
    request of more than one minute... " for example.

    thanks buddy
