HVM Navigator User's Guide - Migration
Setting network segment assigned to activated LPARs as
migration path
When you set any of the network segments such as 1a, 1b, and so on
assigned to one or more activated LPARs as migration paths for the source and
destination HVMs and execute LPAR migration in Concurrent Maintenance
mode, the network load caused by LPAR migration in Concurrent Maintenance
mode affects the network performance on the activated LPARs. So, We
recommend that you set network segments which are not assigned to any
LPARs as migration paths for the source and destination HVMs.
State of NIC or FC HBA ports on destination HVM
When any of NIC or FC HBA ports are down, you cannot execute LPAR
migration in Concurrent Maintenance mode. In this case, an Error icon is
shown in Device Status row in either of the HBA configuration table or the NIC
configuration table in the Migration Config Viewer window. Then, confirm the
network environment on the destination HVM, link NIC and FC HBA ports and
execute LPAR migration in Concurrent Maintenance mode again.
High CPU and network load
When the following items are fulfilled and you execute LPAR migration in
Concurrent Maintenance mode, a timeout for LPAR migration in Concurrent
Maintenance mode may occur.
CPU usage ratio on each of the source and destination HVMs is over 80%.
CPU usage amount by SYS2 is over 0.8 cores.
There are one or more NIC ports which fulfill the following requirement on
the source or destination HVM.
–
A NIC port which is being used over 50% for the bandwidth of the NIC
port
