Migrating a Linux source server with very large storage fails when the migration is
initiated
Migrating Linux source servers with very large storage may fail with the following error found in
the
java.lang.OutOfMemoryError: Java heap space
Suggested action
Increase the heap size on the source server, by performing the following:
1.
Change the current working directory on the source server to the smpagent folder (for example,
/tmp/smpagent
if the agent was automatically deployed.)
2.
Increase the initial memory by changing the following parameters in /bin/hpvmmsmp.conf:
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=512
3.
Start the server migration Source Agent by doing one of the following at the command line:
•
Type ./startHPSMPCnt.sh and then press Enter.
•
Navigate to the smpagent/bin directory and then run the startHPSMPCnt.sh script.
Linux migration might fail when X Windows configuration in not properly formatted
Linux migrations might fail when the X Windows configuration file xorg.conf is not properly
formatted. The configuration file must have at least one ServerLayout section. The presence of log
items like the examples shown below in the hpsmpsvc.log file indicates that the xorg.conf
file does not have any ServerLayout sections:

Suggested action
If the migration fails and the X Windows configuration file on the source server does not have at
least one ServerLayout section, then do the following:
1.
Rename /etc/X11/xorg.conf to /etc/X11/xorg.bak on the source server.
2.
If required, boot the server in single user mode.
3.
Re-run the migration.
4.
After migration is complete, rename /etc/X11/xorg.bak back to /etc/X11/xorg.conf on the
source server.
Partitions created with third-party partitioning tools do not show proper file system
type in the server migration wizard
Partitions created with third-party partitioning tools such as Gnome might not show the proper file
system type in the server migration wizard. This does not affect migration.
