z/VM 4.4.0 Additional Service for VSWITCH and Guest LAN users
The following APARs are not assigned a unique maintenance level.
These updates are recommended for CP systems where Guest LAN
and Virtual Switch
features are being used.
| RSU |
APAR |
PTF |
Brief Description |
| 0301RSU |
VM63282
|
UM30889
|
Exclude virtual NIC from Q3 algorithm so idle guests
can drop out of Q3
Apply VM63282 if you have several Linux servers running
with Virtual CTCA or Guest LAN connections.
The presence of active I/O (usually the Read CCW) may
keep those users in Q3 where they hold system resources
that they do not really need.
|
| 0403RSU |
VM63416 |
UM31038 |
Reset virtual NIC leads to ABEND PRG001 in HCPNID
Apply this APAR as preventative service.
|
| 0402RSU |
VM63385
|
UM31036
|
Support more efficient initiation by network driver
Apply this APAR if you use OSA Express in QDIO mode
(real network hardware) in your VM system.
This update allows your guests with dedicated OSA interfaces
to take advantage of new OSA Express features for processing
data more efficiently.
|
| 0404RSU |
VM63489
|
UM31069
|
HCPVQS ABEND IOL002 when TCPIP controller forced off
Apply this APAR as preventative service.
|
| 0403RSU |
VM63473 |
UM31105 |
ABEND PRG001 on DETACH NIC command from alternate
processor
Apply this APAR as preventative service.
|
| 0601RSU |
VM63448 |
UM31178 |
QUERY LAN ACCESSLIST does not include access list
Apply this APAR if you use a RESTRICTED LAN in your
VM system (QUERY LAN with ACCESSLIST shows you which
users are authorized to COUPLE to a restricted LAN.)
|
| 0501RSU |
VM63519 |
UM31254 |
Reduces the number of overflow frames CP will keep for a
virtual NIC.
|
| 0501RSU |

console indicating an error parsing an OBEY command.
