Cost-Effective High-Availability Solutions with HP Instant Capacity on HP-UX

Example: Manual failover from a complete outage of virtual partitions
Figure 12 shows an example group with two members, but this time the servers are configured with
virtual partitions in the nPartitions db1 and db2. Temporary capacity is not being used in this group.
Figure 12: Initial configuration (virtual partition example)
Now imagine that there is a catastrophic failure on Server 1 leaving vp1, vp2, and db3 inaccessible.
The system administrator needs to start the applications that were previously running on vp1 and vp2
on Server 2. She decides to seize usage rights from vp1. Seizing rights from either virtual partition
leaves db1 with the same number of usage rights: one per cell. (No usage rights are seized from
partition db3; in this example, the applications running there are instead run with reduced capacity
on db4.) The command to seize the usage rights in this example is:
ap1> icapmanage -x vp1
