    The "Short disk read" error was associated with older SPARC boot PROMs that cannot boot from a root partition larger than 2 GB. Did the size of the root partition change?

    root partition change?

    No -- nothing has changed in years and before this, the box ran for
    years without problems. The filesystem is ZFS.

    Update: Further to my message below, I simply tried booting off the disc
    again. This time, I was told of a memory problem and advised to run
    "fmadm faulty". The latter told me the following:

    ======================================
    Fault class : fault.memory.bank 95%
    Affects : mem:///unum=DIMM0,DIMM1
    faulted but still in service

    Description : One or more uncorrectable memory errors occurred.

    Response : The system will attempt to remove the affected physical
    memory page from service after restart of one or more
    services, or the entire system.

    Impact : This error may cause either a system panic or restart of
    one or more user processes, with resulting interruption in
    service.
    ======================================

    So I will replace those two DIMMs and see what happens.
