    Hello Admin wizards,

    after almost two years of painless work we suffered from a power failure
    last morning.
    Even though we have a UPS connected the system did not power down
    regularly as it was supposed to do after the 15 minutes period. So what
    I have now is the following problem:

    The server itself boots up normally, but does not find the connected HSZ
    40 (dual redundant) controllers, better: the defined raidsets, formerly
    known as HSZ40#raid -> /dev/rrz17g and so on. I already figured that the
    symlinks in /etc/fdmns are missing; I recreated them by unpacking the
    fdmns dir from a tarfile, but no success. Am I supposed to do a MAKEDEV
    in /dev/ again?

    Having connected the laptop to the device, one of them says
    --------------------------------------------------
    This controller has an invalid cache module
    Controllers misconfigured. Type SHOW THIS_CONTROLLER
    Power Supply failure cleared.
    Invalid cache -- CLI command set reduced. Type SHOW THIS_CONTROLLER.
    Please-
    see user guide to determine corrective action
    --------------------------------------------------
    The other one seems to be ok, and it shows the raids and units as it is
    supposed to be.
    The user guide suggests to use the command
    CLEAR_ERRORS INVALID_CACHE THIS_CONTROLLER

    but the device responds with
    HSZ_UNTEN > CLEAR_ERRO
    Incomplete command

    it wont accept complete commands but breaks after an unpredictable
    length. Same if I try to issue SET FAILOVER COPY=OTHER - breaks after
    SET FAILO and complains about incomplete command ...

    I wonder why, and how I can get out of this mess ....

    would be grateful for any hint

    regards
    CW
