ETERNUS SF XL-DATA/MV V13 User's Guide

D.1 The Error-log Information

The Error-log information on XL-DATA/MV is automatically extracted, when an error occurs in the following offer functions:

• Initialization Commands
• Transfer Commands
• XL-DATA/MV Daemon
• Status Display Commands

However, when the error which needs investigation occurred, error log information is extracted.

The Error-log information is stored to the two Error-log output files on the following directory.

Solaris Server	/var/opt/FJSVmftf/data
HP-UX Server	/var/opt/FHPmftf/data
Linux Server	/var/opt/FJSVmftf/data

The file name of the two Error-log output files is as follows.

For V13.0	mftferrlog02401,mftferrlog02402
For V13.1	mftferrlog13011,mftferrlog13012
For V13.2	mftferrlog13021,mftferrlog13022

The Error-log information is stored in the two Error-log output files using the following cyclic operations:

1. Stores to the first file.
2. When the size of the first file exceeds 1MB, stores to the second file.
   
3. When the size of the second file exceeds the size as mentioned above, overwrites the first file to store.
   These operations are repeated.

The transfer command and daemon/service both use the same Error-log output file in a local system.
The size of one Error-log output file is 1MB.
The amount of Error-log information storable in a single Error-log output file is about 680 pieces.
Since the two Error-log output files are operated cyclically, about 1360 pieces of Error-log information can be stored.

Free Space for Storage Directory

The directory for storing the Error-log output files must have 2MB or more.
If there is insufficient free space, an insufficient area error message is output. Also, all Error-log information cannot be stored.
This storage directory is used also when extracting the trace file. Refer to "The Trace Information" for details on the trace information.
