Installing and Managing HP-UX Virtual Partitions (A.01.01)

Problem with Adding Unbound CPUs to an Existing Partition

Cause

Appendix B126

In our example, if we want to add an unbound CPU to vpar3, we can

reboot vpar3:

vpar3# vparstatus

vpar3# shutdown -r

When vpar3 boots again, its kernel will create the correct entries for the

unbound CPUs, which are now at x03 and x04. The conﬁguration

becomes:

Because the unbound CPUs are at x03 and x04 and the kernel entries

for vpar3 are x03 and x04, the command to add an unbound CPU to

vpar3

# vparmodify -a vpar3 -a cpu::1

now will be successful.
