Migration Of Lpar Enabling Vc (Virtual Com) Console - Hitachi HVM Navigator V03-06 User Manual

Migration of LPAR enabling VC (Virtual COM) console

VC(Virtual COM) console is a console used by multiple LPARs simultaneously.
VC console accesses each LPAR via an HVM where the LPAR is created, using a
TCP port number assigned to each LPAR. So, when an LPAR, which the VC
console is enabled, migrates, the allocation data of the VC console is
transferred. However, the IP address to access the LPAR and the TCP port
number isn't transferred and is changed to the HVM IP address of the
destination HVM and the port number assigned to the destination LPAR.
However, the maximum definable LPAR number is expanded on HVM version
58-80 or higher and HVM version 78-40 or higher. So, when an LPAR migrates
onto an HVM which VC consoles are already allocated to 16 LPARs, a VC
console isn't allocated to the LPAR. The above event is caused by the
restriction which the maximum available VC number is 16. So, when you
secure one or more available VCs, a VC is allocated to the LPAR.
Migration of LPAR with assigned virtual NICs
An LPAR with assigned virtual NICs(Va-Vd) cannot communicate with the other
LPARs on the source HVM which has communicated with after the LPAR
migrates. When such an LPAR migrates, check the network settings. For
virtual NICs, see Hitachi Compute Blade CB2000 User's Guide, Hitachi
Compute Blade CB320 User's Guide, Hitachi Compute Blade 500 Series Logical
partitioning manager User's Guide, or Hitachi Compute Blade 2500 Series
Logical partitioning manager User Guide.
Ports with Inter-LPAR Packet Filterings set to "Enable" are
assigned to the LPAR to migrate
The LPAR to migrate with Inter-LPAR Packet Filterings set to "Enable" cannot
communicate with the other LPARs on the destination HVM. When the LPAR to
migrate communicates with the other LPARs on the destination HVM, it is
necessary that the Inter-LPAR Packet Filtering is set to "Disable". For Inter-
LPAR Packet Filterings, see Hitachi Compute Blade CB2000 User's Guide,
Hitachi Compute Blade CB320 User's Guide, Hitachi Compute Blade 500 Series
Logical partitioning manager User's Guide, or Hitachi Compute Blade 2500
Series Logical partitioning manager User Guide.
