We are planning a fairly major upgrade tomorrow, starting at 8 am.

1. We will be installing the resilient dCache for the worker pool
   nodes.  This means access to the dCache will be down from roughly
   9:30 to noon.

2. PubDB upgrade.

3. LTS3 upgrades on:    hotdogs    cmswn102    cmswn171-180
   And all these nodes will be inserted into the LCG/grid3 cluster.
   The independent grid3 "hotdog" cluster will be gone.

   This will bring all worker nodes to LTS303 (SL3).

4. The NFS mounted grid3 disk  (cmsstor04) will be exported
   to LCG/grid3 cluster for grid3 compatibility. This, in all
   likelihood, require a reboot of all workers in the LCG/grid3
   cluster.

5. The IBRIX thin client will be installed on the UAF.


Items 3-4 will require most of the day to complete.

Jon
