All nodes should be up and ready on the BYNET.
Data disk expansion is not reversible.
  1. [Complete once per deployment] Enable storage expansion.
  2. Stop the database.
    # tpareset -x -f -y stop system
  3. Run the following command on all nodes to confirm the database is down.
    # pdestate -a
    PDE state: DOWN/HARDSTOP
  4. Display all supported storage configurations for your current system.
    # tdc-expand-storage -d
    No changes are applied to the system.
  5. Display supported storage configurations for your current system with a specific size (TBs per base node).
    # tdc-expand-storage TBs_per_base_node -d
    No changes are applied to the system.
    This example shows how your current configuration will change after expanding storage by 4 TBs per base node (or 8 TB on a 2-node configuration):
    database001-01:~ # tdc-expand-storage 4 -d
    
    Current Configuration:
    ===========================================================================
     Nodes:
             Node Count:    2
    ---------------------------------------------------------------------------
     CPU(Core)/Mem(GB):
             CPUs/Node:    16             CPUs Total:    32
              Mem/Node:   115              Mem Total:   230
    ---------------------------------------------------------------------------
     AMPs/PEs:
             AMPs/Node:    24             AMPs Total:    48
              PEs/Node:     2              PEs Total:     4
    							Storage Total: 16384
    ===========================================================================
    
    
    The system after expanding storage size by 8192 would be:

                                       Storage Total: 16384 => 24576

  6. Expand the system storage (TBs per base node) with any optional arguments.
    Data disk expansion is not reversible.
    # tdc-expand-storage TBs_per_base_node [options]
    where [options] might include -a, -p, or -q. See Optional Arguments for Expanding Storage.
