    URGENT: PowerCLI Script to Redirect /var/core to External Datastore

    vmmonkey Hot Shot

      Long story short, stateless auto deploy environment, 150+ hosts, hostd is crashing and filling up /var/core on the local partition. VMware support has instructed us to redirect /var/core directory to an external datastore. So..

       

      1 - I have already created all the directories (ie /vmfs/volumes/datastore/coredumps/hostname)

      2 - I need to see if I can script this for each host:

       

      rm /var/core

      ln -s /vmfs/volumes/datastore/coredumps/hostname /var/core

       

       

      Also, if I have to do this manually, last resort, is there a way to script enabling SSH on all hosts?

       

      Thanks in advance
