4. Run the cmrunpkg -a command:

cmrunpkg -a pkg1 pkg2 pkg3 pkg4 pkg5

Figure 31 (page 134) shows the load distribution across the nodes with CAPACITY_VALUE

parameter set to finite.

Remaining Cap=1

Node 1

pkg4 (wt=10)

Cap=14

Remaining Cap=4

Node 2

pkg5 (wt=6)

Cap=8

Node 3

pkg1 (wt=4)

Cap=7

Remaining Cap=3

Node 4

First, the pkg4 is placed on Node 2, as this is the first node with highest remaining capacity.

Then, pkg3 is placed on Node 1, pkg5 is placed on Node 3, pkg1 is placed on Node 4,

and pkg2 is placed on Node 1.

5. Now, forcefully halt Node 4 using cmhaltnode –f command to test failover of pkg1, which

is currently running on Node 4. Figure 32 (page 135) shows the failover of pkg1 on Node 2.
