    errdisable_recovery.pdf explains why our HP-Blade suddenly has disabled port (turn red light from initial green) when connected to a switch.

    This blade Catalyst 3020 ports must have been in errdisable/error disable state. First, look for something like

    Downloaded several IOS images. But the that truly boots and up-running in console is c3620-io3-mz.120-7.T.bin for c3600 platform model 3620. A quick look at GNS3-0.5-tutorial.pdf shows that GNS3 only supports some platform.

    What I don’t really know is that can we emulate unsupported platform.

    In our specific case of resource groups:

    clrg status -v – gives the status of cluster
    clrg offline mngrg – takes down the management gui.
    clrg offline prirg – takes down the 3 lb’s (ucip, scap1, scap2).
    clrg offline cache2rg cache1rg – takes down the terracotta instances.
