You can use the management GUI or the
command-line interface to upload support packages to the support center. If
support assistance is configured on your system, you can either automatically or
manually upload new support packages to the support center to help analyze and resolve
errors on the system. To upload support packages, you must have
at least one DNS server and an internal proxy server defined.
You can select individual logs to either download to review or send
directly to the support center for analysis.
You can select from the following types of support packages:
- Type 1: Standard logs
- This option contains many different log files for both the underlying
operating system and the software that includes these critical log files:
- Event log
- Audit logs
- Linux based logs that include
/var/log/messages
These logs are sufficient to diagnose many problems, especially simple
hardware replacement procedures.
- Type 2: Standard logs plus one existing statesave
- This option contains the standard logs for the system and an existing
statesave from any of the nodes in the system. Statesaves can either be a
dump or a livedump. A dump file
is collected when the software restarts for any reason. This file can be
used to understand why the software restarted. A livedump
collects the current state of the software with minimal impact to I/O
operations. The contents of a livedump are similar to the contents of a
dump.
- Type 3: Standard logs plus the most recent statesave from each node
- Contains the standard logs for the system and the most recent statesave from
each of the nodes on the system.
- Type 4: Standard logs plus new statesave
- This option contains the standard logs and a new statesave (livedump) for
all the nodes in the system and packages them with the most recent logs.
When you are deciding what type of package to send, consider the
speed of the upload and if more information is necessary later to resolve the issue. The
standard logs are uploaded more rapidly since the support package is smaller than the
other options. However, the standard logs might not include all the information that is
needed to resolve the problem on the first attempt. Support personnel can require more
data to resolve the problem. If a new statesave (livedump) is not generated shortly
after the standard log, the livedump might not contain the data necessary to resolve the
issue. When you generate the standard logs with the new statesave, you have the greatest
chance of resolving the issue without more information. However, the support package is
larger and can take longer to upload to the support center. You
can also set Common Information Model Object Manager (CIMOM) logging levels. CIMOM
logging provides additional information for advanced error resolution; however,
increasing the level can cause performance issues on the system.
The following table shows the four types of
support packages with the approximate size for a support package for a basic
configuration. The table describes common troubleshooting scenarios that require that
type of support package. Actual sizes of support packages vary based on the number of
volumes and MDisks, the software level, and the compressibility of the logs.

Standard logs plus new statesaves |
90 MB |
790 MB |
- Compressed volumes issues
- Host issues
- External storage issues
- Metro Mirror or Global Mirror issues2
- General performance issues
- Critical performance issues1
|
- Critical performance issues require that both standard logs
and a new statesave are generated and uploaded to the
support center. Generate and upload the standard logs first
and then create the new statesaves.
- Generate a support package on both the source and target
systems in the remote-copy relationship.
