72 The Virtualization Cookbook for Red Hat Enterprise Linux 5.2
5.1 Applying a PTF
You may determine that you need to apply a specific fix or PTF to your system.
For example, an Authorized Program Analysis Report (APAR), VM63895, was opened to
address the problems reported with virtual NIC support. There are three known symptoms
addressed by this APAR:
Linux guests may lose connectivity after shutdown -r now (or any device reset).
Using an External Security Manager (ESM) to authorize a VLAN list may lead to an
FRF002 abend.
Virtual Hipersockets NIC configured with "VLAN nnn" (exploiting Set Global VLAN ID) did
not really filter inbound frames.
The APAR was assigned the following PTF numbers:
z/VM 5.1.0 VM63895 UM31612
z/VM 5.2.0 VM63895 UM31613
There are more details on:
http://www-1.ibm.com/support/docview.wss?uid=isg1VM63895
So, for z/VM 5.2, apply PTF UM31613 as described in the next section.
5.1.1 Determining whether a PTF has been applied
Check to make sure the PTF has not previously been applied.
1. Logon to MAINT and issue the VMFSETUP command to set up minidisks for TCP/IP and link to
them:
==> vmfsetup zvm cp (link
VMFSET2760I VMFSETUP processing started for ZVM CP
VMFUTL2205I Minidisk|Directory Assignments:
String Mode Stat Vdev Label/Directory
VMFUTL2205I LOCALMOD E R/W 2C4 MNT2C4
VMFUTL2205I LOCALSAM F R/W 2C2 MNT2C2
...
VMFSET2760I VMFSETUP processing completed successfully
2. Use the VMFINFO command to query the Software Inventory files. Move the Tab key to ZVM
and type s to select it on the PPF Fileid window:
==> vmfinfo
PPF Fileid - Help
Product parameter files (PPFs) define the environment and key variables
required to process the queries. The following is a list of all PPFs
found on all accessed disks. Select one to continue. The View function
can be used to examine one or more PPFs.
Type a "V" next to one or more PPFs to view their contents, or type an
"S" next to one PPF to select.
Options: S - select V - view
