Re: [Linux-cluster] 2-node cluster and fence_drac

The one I am using is ERA, which is almost the same as DRAC III/XT, except it is an embeded DRAC card on motherboard, compared to DRAC III/XT, which is a seperate added DRAC card. But the telnet prompt does not have the matching pattern in /sbin/fence_drac file, so I just added the following to the file, which works now. Thanks,

Hai,

So, you are saying that if you are using a DRAC ERA card, and you set the $drac_version in the script to $DRAC_VERSION_III_XT, then the fence agent works? If so, we'll patch the agent accordingly. Please confirm.

if (/Dell Embedded Remote Access Controller \(ERA\)\nFirmware Version/m)
        {
                $drac_version = $DRAC_VERSION_III_XT;
        } else {
        if (/.*\((DRAC[^)]*)\)/m)
        {
                print "detected drac version '$1'\n" if $verbose;
                $drac_version = $1 unless defined $drac_version;

                print "WARNING: detected drac version '$1' but using "
                        . "user defined version '$drac_version'\n"
                        if ($drac_version ne $1);
        }
        else
        {
                print "WARNING: unable to detect DRAC version '$_'\n";
                $drac_version = $DRAC_VERSION_UNKNOWN;
        }
        }

    Oops. Sorry. Unsupported version. If you want, you could hack the
    agent
    script (it is in perl) and get it to accept that version and just
    *see*
    if it works -- it might. I tried looking for documentation for that
    firmware rev and couldn't google any. If you know of some, drop me a
    line and maybe we can get something working - or at least know if it
    *will ever* work. :)

    BTW, the agent supports DRAC III/XT, DRAC MC, and DRAC 4/I.
