Grouping Multiple Cages into one VM

In this example we will group cx24y2c{0,1,2} into one VM (cx24y2)

Setup cx24y2 as one large VM

Set the Software Repository

am --set --cray_bin  /usr/local5/kbferre/REL_1_4_45/install cx24y2

Set the VM

am --set --rs_vm cx24y2/ cx24y2

Make sure all node roles in CIT DB match

am --rs_role --flat cx24y2 | grep -v seastar | grep -v l0

Note: you must ensure that all WAMD's are killed that correspond to the individual configuration

Put it back to 3 individual VM's

First ensure the WAMD corresponding to the grouped VM is killed

am --set --cray_bin cage0_install_tree cx24y2c0
am --set --cray_bin cage1_install_tree cx24y2c1
am --set --cray_bin cage2_install_tree cx24y2c2
am --set --rs_vm cx24y2c0/ cx24y2c0
am --set --rs_vm cx24y2c1/ cx24y2c1
am --set --rs_vm cx24y2c2/ cx24y2c2

Return all of the node roles to what they were before before the change

Configure cx24y2c0 and cx24y2c1 as one VM

In this example we will group cx24y2c{0,1} into one VM cx24y2c0_1

Set the Software Repository

am --set --cray_bin  /usr/local5/kbferre/REL_1_4_45/install cx24y2c{0,1}

Set the VM

am --set --rs_vm cx24y2c0_1/ cx24y2c{0,1}

Start the harness

 harness --init cx24y2c{0,1}

rs_init the VM

 rs_init cx24y2c{0,1}

Start WAMD

  harness --wamd cx24y2c{0,1}

Ensure the proper node roles

Boot the Login Node

Boot the compute nodes

  rs_boot --qk cx24y2c{0,1}
